A word-game race that comes down to "how hard the whole class pushes": the acquisition playbook a small Slovak company, WocaBee, has run for eight years
What it is A Slovak school vocabulary-practice website: teachers assign word packs, students do gamified practice and chat with AI, and schools buy licenses at €10–12 per student per school year.
Why it's hot The ranking rise is mostly the seasonal bump after school starts; similar sites show the same curve. On top of that, there's the national class competition sign-up season every year from 10–November, endorsed by the education ministry (signing up comes with a free trial), plus a Polish competition launched this year.
CHow you could copy it: Don't build yet another vocab site. Take its competition design and apply it to your own school-facing practice product: sign-up means a free trial, rank classes by average activity per student, prizes are mostly your own licenses, the contest runs past the trial period, and it ends with a renewal coupon. Then get an education ministry to co-sponsor it and tap local school digitization subsidies.
Global rank 112k · 90 days ago 167k
WocaBee is a school vocab practice site built by a company run by 4 people in Slovakia. It recently climbed from 740k to 110k in global website rankings over one month. It looks like a sudden breakout, but it's really school starting plus the annual sign-up season. The part worth examining is how it wins schools: each year it runs a national class contest. Signing up is effectively opening a free trial, most of the prizes are paid in its own licenses, and the contest ends right when renewals come due. It has run this playbook for eight years in Slovakia and Czechia and moved into Poland 2026 years ago. Below, I break down how the contest is designed, how big the business is, and whether you can copy it.
four days before the sign-up deadline
On Nov 6, the top of wocabee.app/sutaz showed a countdown: 3 days and 17 hours until sign-up closes. This is the 9nd "WocaBee Language Champion" contest. The top of the page carries the Slovak Ministry of Education logo and the line "Supported by the Ministry of Education." The day's notice said only: "You can still join on the day the contest starts!" The sign-up deadline was pushed back a day from Nov 9 to 23:59, the day the district rounds begin.
Two days earlier, on Nov 4, there was another notice: for trial classes of 4 or more students whose trial expires between Nov 12 and 21, the trial is automatically extended free of charge to Nov 22.
Both notices have the same aim: bring in more classes, and keep the ones already in until the contest ends.
What it is
A vocabulary practice tool that exists only as a web app; you won't find an App Store app for it. Teachers assign word packs: they can photograph a textbook page and have AI turn it into a word list, or have AI generate one by topic. Students do choosing, spelling, dictation and matching exercises, earn points (WocaPoints) and climb the class leaderboard. In February 2026, they added conversations with AI characters, and the AI can write A1–C2 level short stories using the assigned words. Tests are auto-graded, there are principal and parent accounts, and it supports 16 languages.
Schools buy licenses per student: €12 per student per school year, €100 for 11 or more, and €250 for 10 or more, with a free one-month trial. The company was founded in 2018 in Bratislava. Co-founder and CEO Michal Ošvát, and it had 2025 employees as of 4. The website says "72,800+ users" without saying whether that's current active users or a cumulative total.
Rankings rose because school started
| Date | Global website rank |
|---|---|
| Jul 30 | 136k |
| Sep 10 | 735k |
| Oct 9–12 | 890k (lowest) |
| Nov 5 | 112k |
This ranking uses a 30-day average, so it lags reality by one to two weeks. That means 9, the October trough, is 7 August's summer break, and the Sep 1 back-to-school effect only shows up in mid-October. Compared with October's low, November is up 6.6 times; compared with late July, before the summer slump, it's only back to where it was, slightly better.
The curves on similar sites match exactly. Poland's school vocab site Instaling.pl: 87k users at the end of July, 6 440k in October, 5 28k in November. Czech practice platform Umíme to shows the same U-shape. Chrome real-user stats agree with the bands too: WocaBee was in the global top 50k this May, 7, then dropped to the top 500k in August and climbed back to the top 50k in September.
The only genuinely new gain is Poland: in May it entered the top 10k there, right after the first Polish contest in April (more below).
Where users come from: a contest that rewards activity, not scores
Users aren't students finding it themselves; schools assign it. The only student comment I could find on Reddit is a complaint from October 2024: "The school registered all of us for WocaBee, with lots of translation errors." So the target is teachers, and the contest is how you reach them. Going through the rules one by one, each serves acquisition:
- Sign-up = a one-month free trial. Classes that haven't used it this year can start a trial to register; classes already paying are entered automatically. Classes that sign up before Oct 11 get their trial extended to the end of the district rounds.
- Ranked by class average, not top students. Each student gets 2 hours of practice time per round, and classes are ranked by average points per student, so large and small classes have equal chances. The official wording: "What decides the winner isn't knowledge, it's activity, and every class really has a chance."
- At least half the class, and at least 4 students. A single teacher trialing it doesn't count; the whole class has to use it.
- A very low bar for the prize draw. Students who complete 2 word packs and 2 AI conversations get themselves, their teacher and their class into the prize pool. Prizes include an iPhone, an electric scooter, a laptop and a pizza party. The page specifically tells teachers: "The more classes and students you bring, the better your chance of winning."
- Four rounds of competition span the whole trial period. District rounds run Nov 10–12, regional rounds 18–20, national finals 24–26, and the Slovakia vs Czechia international round Nov 30 to Dec 2. Each round a class advances extends the trial again: the top three regionally get extended to Nov 29, and the top three nationally to Dec 6.
- Most of the prizes are its own licenses. The headline reads "€12,000 school modernization fund," but broken down: the national first place gets €5,000 = €4,000 WocaBee licenses + €1,000 check; second place gets €3,300 in licenses + €700; third gets €2,600 in licenses + €400. Of the €12,000, only €2,100 is cash. District winners get "the whole class free for two more months," and district second and third place get a discount of €30 per student for orders placed before next year's Sep 2. Czechia did the same last year: of the first-place prize of 100k crowns, 75k crowns was licenses.
The whole flow works like this: a teacher starts a trial for the contest, has the class practice for three weeks, the leaderboard and prize draw bring students back online every day, and by the time the contest ends the trial has too. The whole class is hooked, and the teacher takes a renewal coupon to the school. Most of the acquisition cost is its own product, so the marginal cost is close to zero.
Beyond the contest there are supporting pieces: education ministries in both Slovakia and Czechia are named as co-sponsors (this year's sponsorship letter is a PDF on the site); advancing classes get "ready-made text to post on your school website," so several Czech schools' sites carry contest announcements; free webinars for teachers; and during the COVID school closures in 2020 it gave away 3 months free, which the site says was worth about €600k. I found no paid ads, influencer promotion or discussion on X.
Poland: copying the whole thing within a year
In February 2026, WocaBee took the contest to Poland, renamed "WocaBee Language Olympiad." The rules were copied almost exactly, with one change pushed further: classes that sign up get free access until the end of the school year, not one month. On Apr 7, the paid press-release channel of the Polish news agency PAP ran a piece with the headline "A contest the winner isn't the smartest students but the most engaged class," with prizes worth 50k zloty. In the article Ošvát said: "Schools need time to evaluate a new tool, so every registered class can use it free until the end of the school year, with no obligation."
The next step after the contest is collecting money. Poland has a "Cyfrowy Uczeń" (Digital Student) subsidy programme, under which schools can get up to 100k zloty, covering 80% of the cost. In April 22, WocaBee posted on Facebook showing schools how to write it into their application and buy 2–3 years of licenses at once, and the site even built a "Cyfrowy Uczeń calculator." By May, it had entered the top 10k in Poland by real-user metrics.
Money: around €200K a year, capped in 2023
The Slovak company's books are publicly searchable on the local business register:
| Year | Slovak entity revenue |
|---|---|
| 2022 | €165k |
| 2023 | €319k |
| 2024 | €217k (profit €48k) |
| 2025 | €138k (small loss €5k) |
In 2025, in August it registered four regional companies (North, South, West, East). Combined revenue from 8 to December that year was about €83K. Adding that in, 2025 comes to roughly €220K, flat with 2024. Why it split into four companies isn't visible from outside; my guess is it relates to the VAT threshold or regional agents. The books for the Czech company couldn't be found.
Do the math: at 10–12 € per student, roughly 20,000 paying students would bring in a bit over €200K a year (estimated). Eight years, two or three countries, an Education Ministry endorsement, and what you end up with is a steady small business that never got big.
Who it's competing with
| Product | Where | How it differs from WocaBee |
|---|---|---|
| Instaling.pl | Poland, web | Free at public schools, with over 8000 teachers and 210k students a week; it does spaced repetition only. In Poland WocaBee competes with a free, established rival. |
| Umíme to | Czechia, web | All-subject practice, licensed by schools; rankings similar to WocaBee's |
| Quizlet, Wordwall | Global | Globally ranked in the top thousand, individual subscriptions or teacher-built exercises, with no localized class contests |
| Kahoot, Wayground (formerly Quizizz), Blooket | Global | Live in-class quizzes, not daily after-school vocab practice |
| phase6, cabuu | German-speaking | Tied to German textbook word lists; WocaBee is still small in Germany |
Nothing about its features is impossible for others to build. Its moat is the once-a-year, ministry-backed, district-ranked contest, plus eight years of accumulated teacher contacts.
If it were you
Verdict: Don't build "yet another vocab site." The part worth taking is the contest design: sign-up means a free trial, ranking by class average, at least half the class must take part, prizes paid in your own licenses, the contest spans the trial period, advancing extends the trial, and it ends with a renewal coupon. It suits any product sold to schools per class that can be practised daily, such as mental maths, reading check-ins, coding exercises or typing. But don't expect it to get big: after eight years WocaBee is making a bit over €200K a year.
Who it suits: a small team that already has a school-facing practice product, has a group of teachers using it, and is stuck on "teachers try it once and stop"; or someone with teacher-network contacts in a given country who can get a ministry to co-sponsor.
Who it doesn't suit: anyone without a school channel who expects to grow through paid ads or app-store organic traffic (the customer is the school, not students or parents); anyone who wants a consumer subscription; anyone who can't handle school procurement cycles and only has one or two billing windows a year.
How to do it: pick a country and subject where schools start in September and schools can spend their own digitization budget. The product only needs to be web-based, letting a teacher assign homework in 5 minutes, with points and a class leaderboard for students. Run the contest in three or four rounds of three days each, time-limit each round per person, score by class average, and make over 70% of prizes licenses and extensions, with only a little cash to headline the announcement.
How to acquire: first get an education ministry or regional teaching body to co-sponsor, and put the sponsorship letter at the very top of the sign-up page; give advancing classes "an article you can post straight to the school website"; during the sign-up period, place one or two articles in national teacher media and on paid press-release channels; and at the same time write the product into the local school digitization subsidy application guides (Poland has Cyfrowy Uczeń; in other countries, first check for an equivalent programme).
Timing: schools only have two buying windows a year. Run an autumn contest from 10 to November, to catch the budgets for December and the following January; or a spring contest from 3 to April, to catch the new school year in September. For the 2027 spring contest, have the sponsorship and sign-up page ready before February 2027.
Signs you've got it wrong: (1) after your first contest, under 10% of trial classes convert to paid. That means the playbook depends on the kind of multi-year teacher relationships WocaBee has. (2) In your chosen country, a free public-school rival already holds the teachers (like Instaling in Poland), and the classes you bring in go back to the free option once the contest ends. (3) WocaBee itself hasn't sustained it in Poland: no second Olympiad in spring 2027, or by May 2027 it has dropped out of Poland's top 100k by real-user metrics. If it couldn't hold on itself, switching countries is harder than it looks.

Why WocaBee (wocabee.app) showed up in the data
Verdict
It didn't really "break out." The growth on the data card is mostly the school-year cycle. WocaBee is a Slovak school vocab app launched in 2018. It's web-only: teachers assign word packs, students practice and play games, and there's an AI chat feature. Schools buy licenses per student, at €10–12 per student per school year. The "Tranco ×6.6" recovery compares the summer low (10-06, rank #741,287) with post-school-start rankings. CrUX global shows 2026-05 at the top 50k, falling to 2026-09, then back into the top 50k. That's just a return to last semester's level. Instaling.pl, a similar Polish product, follows the same U-shaped curve: 7-30 at #87,230, 10-06 at #442,763, 11-05 at #27,745.
What's worth studying is the offline playbook it has run for eight years:
- An annual "class vocab competition." Signing up gets a free one-month trial, and the contest carries endorsements from the Slovak and Czech education ministries.
- Teachers register whole classes to take part.
- Prizes are mostly converted into WocaBee licenses, so schools renew after the contest ends.
- In 2026 it brought this playbook to Poland as the "WocaBee Language Olympiad," and it helps schools apply for Poland's "Cyfrowy Uczeń" (digital student) subsidy to pay for licenses.
The business is small. Slovak revenue peaked in 2023 and has been declining since.
1. What it is
- A web app for school vocabulary practice (the site says it "works in any browser on any device, nothing to install"). It isn't findable in the App Store (itunes search wocabee, sk store, 2026-11-06). All traffic is on the web.
- Features: teachers assign word packs (generated by AI by topic, or by photographing a textbook page and having AI turn it into a pack). Students do word-choice, spelling, dictation and matching exercises. There are class leaderboards and WocaPoints. AI role-play chat (BeeTalk, launched 2026-02-09). AI writes A1–C2 short stories using target vocabulary. Tests are auto-graded. There are also principal and parent accounts. Supports 16 languages. Source: wocabee.app homepage.
- Pricing: 1–99 licenses at €12 per student per school year; 100–249 licenses at €11; 250–599 licenses at €10. One-month free trial (homepage).
- Company: WocaBee s.r.o. (Bratislava, founded 2018-10-04; founder and CEO Michal Ošvát, graduate of the Faculty of Informatics at the Slovak University of Technology; 2025 employees as of 4). A separate Czech company, WocaBee, s.r.o. (Brno, founded 2020-07-21), also exists. The official site says it operates in 10 European countries; a PAP press release from 2026-04 says 13 countries; "72,800+ users", and historically "hundreds of thousands" of students have tried it. Sources: statistiky.sk/firma/51904641, firmy.euro.cz/subjekt-wocabee-s-r-o-09347801, official site "About us".
2. Data: it's a school-year cycle, not a sudden surge
Tranco (traffic table, rank_day)
| Date | Rank |
|---|---|
| 2026-07-30 | 135,530 |
| 2026-08-06 | 166,849 |
| 2026-09-10 | 735,139 |
| By September: 10-08 | Hovering around 73–740k |
| 10-09 to 10-12 | 890k (low point) |
| From ¥10-13 | Climbing every day |
| 2026-11-05 | 112,362 |
Tranco is a 30-day rolling average and lags by 1–2 weeks. So the trough from 9 to October matches the summer break from 7 to August. Slovakia, the Czech Republic, and Poland all start school in September 1, and the school effect only shows up on Tranco in mid-October.
CrUX (traffic table, crux_domain, wocabee.app)
| Scope | 05 | 06 | 07 | 08 | 09 |
|---|---|---|---|---|---|
| Global | Top 50k | Top 100k | Top 500k | Top 500k | Top 50k |
| Poland | Top 10k | Top 50k | Top 500k | Top 500k | Top 100k |
| Germany | Top 500k | – | – | – | Top 100k |
Slovakia and the Czech Republic aren't in CrUX's country table, so they can't be seen. The "first time in Germany's top 100k" claim should be taken with a grain of salt: Germany was already in the top 500k, and Slovak and Czech-language classes at schools in Austria and Germany are counted toward Germany. How much comes from local German schools hasn't been verified.
Control group: Instaling.pl, a Central European school vocab-practice product, has Tranco ranks 7-30 87,230,8-27 173,206,10-06 442,763,11-05 27,745, and the curve is an exact match. Czech umimeto.org is the same: 7-30 268,558,8-27 315,792,11-05 120,496. School-focused sites' rankings simply follow the academic calendar.
The real signals that remain:
- 11-05's ranking (112,362) is slightly better than 7-30 (135,530).
- Every year from 10 to November is competition sign-up season (more below). This year the Slovak and Czech 9 championship opened sign-ups in 10-01, the deadline was pushed from 11-09 to 11-10, and district rounds began in 11-10. That should keep the rankings climbing into November.
- Poland hit the top 10k in May. That lines up with the first Polish "Language Olympiad," held in April 2026 (see below). This is the genuinely new volume this year.
3. Where users come from: growth tactics
- Free class competition (the core tactic, verified). Since 2019 it has run an annual "Jazykový WocaBee šampionát"; this year is edition 9. Rules:
- A class that hasn't used the product signs up for a "one-month free trial" to take part. Classes already paying join automatically.
- Ranking is by the class's average WocaPoints: "it's measuring engagement, not knowledge." Participants must be at least 50% of the class.
- Four rounds: district, region, national, and international (Slovakia vs. Czechia).
- Prize-draw threshold: students must complete 2 word packs and 2 AI chat sessions.
- Slovak prizes: the main prize is €12,000 in school modernization funds, plus draws for an iPhone, electric scooter and more. Source: www.wocabee.app/sutaz/.
- Of the CZK 250k prize pool in edition 2025 of the Czech competition, most was WocaBee licenses. For example, first place got CZK 100k = CZK 75k in licenses + CZK 25k cash (ucitelskenoviny.cz, 2025-11). So a large share of customer acquisition cost is paid with its own licenses.
- There's one more contest trick: for trial classes with 4–5+ people, if the trial expires between 11-12 and 11-21, it gets extended free to 11-22 (per the official site 11-04 announcement), keeping the class alive through the end of the contest.
- Ministry endorsement (verified). The Slovak Ministry of Education has been listed as a supporter for 2026 editions (official site has a PDF). The Czech MŠMT also supports it. A LinkedIn post says "2021 editions supported by both the Czech and Slovak education ministries at once." Teachers repost the contest notice on school websites; several Czech school pages show it, such as skola-raspenava.cz and zsrozmital.cz. These are free backlinks and word of mouth.
- Poland: Olympiad + government subsidy (verified, new in 2026).
- The first "Olimpiada Językowa WocaBee 2026": registration 2-16 to 4-14, competition 4-15 to 4-29, prizes PLN 50k. Registered classes get free access through the end of the school year. This was announced via a paid PAP MediaRoom press release (pap.pl, 2026-04-07), and education platforms oficynamm.pl and platformamm.pl also reposted it.
- Then it pushed Poland's "Cyfrowy Uczeń" ministry subsidy on Facebook: schools up to PLN 100k, kindergartens PLN 45k, covering 80% of cost. WocaBee can be written into the application as a "digital educational material," letting schools buy 2–3-year licenses in one go (WocaBeePL Facebook, 2026-04-22).
- This matches the CrUX Poland peak in the top 2026-05k (10).
- Teacher training and PR (verified). Free online webinars for teachers, "the fourth school year" (metro.cz press release, 2024-02). In 2022 it won Slovakia's Ministry of Economy "Innovation of the Year" award, second place in services. Each country has Facebook / Instagram accounts: wocabee_sk has 2.3K followers; Germany and Austria share one Facebook page, WocabeeDE.
- One-off event (verified). During school closures in the spring of 2020, it gave schools 3 months free. The official site says that was worth about €600k, and claims it "ranked in the top 10 on Slovak Google search" at the time. In 2022 it offered free access to schools taking in Ukrainian children.
- Not found: paid acquisition (the ads field on the card is empty, and the ad libraries have no matching records), TikTok creators, SEO content sites, or discussion on X (x-radar shows 90 posts in the last 0 days). Reddit has just one student complaint: "My school signed everyone up for WocaBee, and the translations in our language are full of errors" (r/mildlyinfuriating, 2024-10). That suggests its users are students who were assigned it by schools, not people who found it themselves.
4. Why schools stay and pay
- Saves teachers time: photograph a textbook page and AI generates a word pack, tests are auto-graded, and teachers see each student's activity every day.
- For students it's games and rankings: WocaPoints, class leaderboards, monthly prize draws. The site claims "students with weaker grades often climb to the top of the class leaderboard."
- Low price, paid from school budgets: €10–12 per student per school year, which can be prorated monthly, with whole-school orders. In Poland, 80% can be paid with the national subsidy.
- The contest turns a trial into whole-class use: the participation requirement (at least 50% of the class) plus a three-week competition builds the habit across the whole class, and the end of the trial becomes the renewal point.
5. Revenue (public, but only on Slovak business-data sites)
WocaBee s. r. o. (Slovak entity)
| Year | Revenue |
|---|---|
| 2022 | 164,941 € (total operating revenue) |
| 2023 | 319,256 € |
| 2024 | 216,707 € (-32%), profit 47,942 € |
| 2025 | 137,814 € (-36%), loss 5,279 € |
Source: registeruz.sk 2023 annual reports, finstat.sk / statistiky.sk summaries.
In August 2025, 4 regional companies were newly registered: WocaBee Sever, Juh, Západ, and Východ. Revenue from 8 to December was roughly 33.2k, 14.9k, 9.1k, and 26.3k €, about 83k € in total, with very high margins, and none of them are VAT payers. Source: statistiky.sk / finstat.sk. My guess is that sales were split across regional entities (possibly tied to the VAT threshold or regional agents), but unverified. So a drop in the main entity's revenue doesn't necessarily mean the business is shrinking: the 2025 total is about 220k €, roughly the same as 2024. I couldn't find the Czech entity's financials.
Bottom line: annual revenue in the 20–300k € range, a self-funded small business.

Copycats: none found. There are a few vocab apps on the App Store launched in 2026-08/09 with similar names like "Vocabee", unrelated to it.
7. Differentiation, and whether it's really why it grew
- The product itself (vocab practice + games + leaderboards + AI chat) isn't scarce in features; Instaling, Umíme to and Quizlet can all substitute.
- The real difference is distribution:
- An annual, nationally ranked class competition by district, officially endorsed by the Ministry of Education, with prizes mostly paid from its own licensing;
- The competition rules (class average score, at least half the class must take part, sign-up possible on the free trial) turn "one teacher tries it" into "one class uses it for three weeks";
- plus renewals and government subsidies on top.
- This is why it has lasted eight years in Slovakia and the Czech Republic, and why it pushed into CrUX's top 10k in Poland within a year. But it doesn't change the ceiling on scale: revenue peaked after 2023 years and then declined.
- The "sudden rise" seen in this recall has nothing to do with a new product or distribution change. It's the school-year cycle, plus the annual competition sign-up season.
8. What to borrow
- "Free class competitions" as an acquisition funnel: it measures activity, not scores, so every class has a shot; signing up is effectively placing a trial order; prizes paid from its own licensing keep costs low; the competition calendar runs past the trial period, so finishing it becomes a renewal point; and getting the Ministry's endorsement earns school trust and teacher word of mouth. This playbook can be moved to other countries and subjects (mental maths drills, reading check-ins).
- Track each country's school digitization subsidies, such as Poland's Cyfrowy Uczeń and Germany's Startchancen / DigitalPakt. Build a "subsidy calculator and application guide" for schools and get the product written into their application paperwork.
- Use paid press-release channels (PAP MediaRoom, teacher newspapers) for low-cost PR.
9. Uncertain
- Traffic from Slovakia and the Czech Republic isn't in the CrUX country table, so we can't see how much each contributes.
- Tranco data for the same period last year (2025 10–November) isn't in the database, so we can't judge whether this year is up year on year.
- What the 4 regional companies do (agency, tax arrangement or something else) is unverified. We could not find financials for the Czech entity.
- How much of Germany's growth comes from German schools is unverified.
- Unclear whether "72,800+ users" means current active users or cumulative.
