"Put a price on your team's worst player": a 350k-view video sends an amateur team fantasy app to #1 in Spain's Sports chart

OnzeGol is a Spanish-language app: it sets up a private fantasy league for the pickup team you play with each week. Players are you and your teammates, and after games everyone rates each other anonymously. It launched in Oct 31, built by one person, completely free. Spain has only 21 ratings, yet since Nov 1 it has been on Spain's App Store Sports Free chart almost every day, at #1. It spent no money on paid acquisition. Growth came from a TikTok video that made people want to forward it to their team chats, plus a product structure where "you can't play alone, you need the whole team." It's small, and almost no one has noticed it.

Oct 26, "eres ese?"

The account @onzegol.app started posting TikTok videos daily in Oct 21. On day six, Oct 26, it posted a short clip with only the caption "eres ese? tu solución 😉" (Is that you? Here's the fix), tagged #ligamunicipal #futbol7 #pachanga #vestuario, meaning municipal league, seven-a-side, pickup football, locker room. By Nov 6 the video had 352k views and 13k likes, with 9,351 shares (TikHub, 11-06).

The share count is the key: shares were 2.7% of views, far above a typical video. The account's other captions follow the same pattern: "etiqueta al que menos valdría de tu equipo" (tag the teammate worth the least on your team), "mándalo al grupo con tus amigos" (send it to your group chat). The video itself is a meme calling out a teammate, and viewers forward it to their team's WhatsApp group.

The most-liked comment (118 likes) reads: "Was looking for it in the Play Store... just found out it's a web app, I'll try it." The second most-liked (45 likes) says: "Can you make one for volleyball or basketball? Great idea." Several others say "can't find it in the App Store," "not on the Play Store," or "it says I'm a bot."

What it is

The first line of the store description: "OnzeGol is fantasy for your amateur team. Not the pro-player kind, the kind for the people you play with every week."

• Set up a league in a minute, send the link to teammates, and each person claims which name on the roster is theirs;
• Each round, pick your starting lineup with a virtual budget, choose a formation, and the captain's points are doubled;
• Before the game, sign up for who's playing; after the game, everyone anonymously rates the teammates who played and picks an MVP;
• Scoring is based on ratings, goals, assists, MVP, and clean sheets, with overall and per-round rankings. The store copy says it plainly: "como los fantasy de la tele" (like the fantasy games on TV).

Free, no money changes hands, no in-app purchases; the terms state "free, no real money involved." The iOS package is only about 3 MB, Spanish only. The Android version says "muy pronto" (coming soon).

How much it actually grew is small

App Store Spain storefront, 11-01 to 11-06. 11-06 total ratings, all 21 stars... 5

"#1 in Sports" sounds big, but the bar in Spain's Sports category is low. On the overall free chart it sits in the low hundreds, and a day likely means only a few hundred downloads (estimated, Apple doesn't publish download counts). It also charted in Sports across 15 Latin American stores, including Mexico (best #10, 11-04), Uruguay, Costa Rica, and Argentina, but those stores have almost only 0 or 1 ratings, just a few downloads. Actual installs are probably under a few thousand (inferred). The TikTok account has 558 followers, Instagram 1,213 (11-06).

Where users come from: whole teams arriving at once

Web first. The viral video was posted by 10-26, back when there was no app yet, and it sent viewers to onzegol.com. Around Oct 28, amateur teams were already posting their invite links on Instagram: the seven-a-side team Santos FC posted onzegol.com/unirse/... and thanked @onzegol for "making such a nice app"; Blue Bokerones CF posted "Fantasy Bokerón is here! This morning we created our team fantasy on @onzegol"; another team, perrosdelanochefc, put the invite link in its profile bio.

Then the app, and existing squads move over as groups. It launched on iOS in Oct 31. A review that day read: "My friends and I played on the web before, it was good, and now the app is even easier." The next day it was #1 in Sports. In Nov 1, the account posted "send it to the group, create it now" and got 86k views.

The unit of acquisition is a group, not an individual. One person creates a team and shares it in WhatsApp, and teammates can't pick lineups or rate each other unless they join. One conversion means 7 to 20 people, and they're strongly connected teammates. When the team announces it on its own Instagram, that's another round of exposure.

No sign of paid ads was found: nothing in the Meta Ad Library, and on TikTok only the one viral video stands out while most others have a few hundred to two thousand views, which doesn't look like paid promotion. It has no presence in media, on X, Reddit, or Product Hunt. The early five-star reviews read like friends cheering ("Un 10 sin duda"), and whether they were from friends or family hasn't been verified. The developer on the App Store is listed as LUCAS BELTRAN RUA, with only this app under the name, and the background is unclear.

Why this one, and why now

1. No tutorial needed. LALIGA Fantasy, Biwenger, and Mister Fantasy are hugely popular in Spain, and everyone understands budgets, captain doubling, and value swings. OnzeGol only swaps the pro players for you and your teammates.
2. Built-in topic. "Who's the worst on our team" and "how much is the goalkeeper worth" are already arguments that break out in team chats every week. Anonymous peer rating turns that argument into a leaderboard.
3. Timed to the season start. 10, November is when amateur leagues in Spain start their new season, and team chats are just heating up.
4. Easy to chart. A few teams moving in as whole groups in one day is enough to reach #1 in the Sports category, and a chart spot brings a bit more store exposure.

Who else is doing the same thing

OnzeGol didn't come up with this idea first. In the second half of 2026, at least four or five others were building it, and none took off:

Panka launched two months earlier, is the closest in gameplay, and still shows 0 ratings in Spain. The gap isn't features, it's distribution: OnzeGol's founder posts memes on TikTok every day, and one of them hit. Teammates rating each other (not a coach) makes the joke funnier, and native Spanish plus tags like #ligamunicipal target the right crowd, but that's not enough on its own. Someone has to see it.

What we don't know yet

• No public data on how many teams there are or how many people rate each week. Amateur leagues play once a week, and it's unknown whether it can hold attention past the novelty. Since 10-26, there hasn't been a second hit, and in the last few days new ratings are only single digits a day.
• It has no plans to charge anything. Whether this type of product can make money hasn't been proven by anyone: Squadcard charges organizers, and it also has 0 ratings.
• No Android version yet, and several people in the comments are looking for it on the Play Store.

If it were you

Verdict: Worth a try, but be clear about what you want. Building a "friends-league fantasy" has a low technical bar, and markets outside Spanish-speaking countries and Android are still empty. The hard part is distribution, and nobody has shown how the money works.

Who it fits: One or two people who already play in an amateur league or are part of a sports community, who can film and are willing to post short videos every day. Someone who wants a low-cost product that grows through word of mouth and earns users before money. Native speakers of Italian, Portuguese (Brazil), English (UK Sunday league), French, or German, or those building five-a-side, basketball, or padel, all have room: Italy already has Panka and FantaCalcetto but neither has taken off, and basketball already has Rookies: pachangas de basket (on the App Store 10-20).

Who it doesn't fit: Anyone who wants to rely on subscriptions or in-app purchases from day one, or who won't film videos themselves and expects App Store search or ads to bring users (Panka and Squadcard are examples: full-featured, yet 0 ratings).

How to do it:

1. Start with a web app, and prove that "one person creates a team, the whole team joins" through an invite link before building an app.
2. Copy the gameplay of the professional fantasy games already popular locally (Fantacalcio in Italy, FPL in the UK) and just swap the players for teammates. Anonymous peer ratings plus MVP voting are essential, since that's the source of the buzz.
3. Once you have dozens of active teams, launch the app and let existing teams migrate in a single day, aiming for a low-bar category chart. Launch on both platforms at once, so you don't end up like OnzeGol, with comments constantly asking "where's Android?"
4. Set money aside for now. Later you could test charging team organizers a little (advanced stats, season recap posters, jersey number cards), or sell to venues and league organizers, but nobody has validated this yet (inference).

How to get users: Named-tag short videos. Write captions that make people want to @ a specific teammate ("@ the most expensive guy on your team", "our keeper is only worth 13M"), and watch shares, not views. Then find local amateur clubs on Instagram, help them set up their league, and ask them to announce it.

When to move: Follow the season. European amateur leagues start in 9 and run through November; after the winter break there's a second window from 1 to February. Launch before mid-January of 2027, or you'll have to wait for the next season in September.

Signs you've got it wrong: ① By mid-December, OnzeGol's Spanish ratings are still under 50 and it has dropped out of the top 20 sports chart, meaning this was a one-off video boost and retention couldn't hold. ② It, Panka, or Squadcard publishes a paid plan and months later still no one pays, meaning this category just doesn't make money. ③ Conversely, if OnzeGol launches on Android and ratings start rising across Latin American storefronts, skip Spanish-language and move to another country or sport.
