"How much did the people who bought at launch lose a month later?": a Paris card-valuation app cut its own price tables into short videos

Collektik is an app that scans Pokémon cards and values them against European market prices. It launched in Sep 11, and the company behind it is based in Paris, with a CEO aged 22. The product itself isn't new: France already has three or four similar apps that are much bigger. What's worth watching is its acquisition approach. It cuts daily-updated price data into videos about "these cards rose, these fell," with a separate TikTok account for each language. After the German account had run for a week, the German chart started moving. Below: what it is, how big it has gotten, and whether you can copy the approach.

A video about the "30 anniversary cards dropping in price"

On Oct 2026 10, the French TikTok account @collektik posted a video titled:

Ils ont acheté les cartes 30 ans le jour de la sortie, voici le prix 1 mois plus tard 📉 (They bought the 30 anniversary cards on release day. Here's the price one month later)

The caption only added "Collektik, lien en bio" (Collektik, link in bio). By Nov 6, the video had 95k views and 77 comments (TikTok, 11-06). The comments argued over one thing: some said "it'll drop more before Christmas, then it'll stabilize," some said "it's down, so I'm buying more," and others said "these were always meant to be collected, not flipped." The most-liked comment was a single photo with the caption "I have a box."

Five days later, on Oct 15, the same account posted "Everything Pokémon has coming out before Christmas." It was its most popular post, with 128k views and 2,080 shares. The top comment was "6 is going to be a battle that day." It referred to the release date of the Nov 6 new set "Règne Delta" (German name: Delta-Herrschaft), which is today.

2026 is Pokémon's 30th anniversary, and a wave of new collectors just bought in. Their one question: what's my card worth right now? Collektik's video answers it, then tells you the app can check the cards you own.

What it is

Point your phone camera at a card and the app recognizes the card, language, set and variant. In "Turbo" mode you run a stack of cards past the lens one after another and the total value adds up as you scan. Graded cards (PSA, CGC, Beckett and others) get their grade and certificate number read straight off the label. Prices come from Cardmarket (Europe's biggest card trading platform) for raw cards, eBay sold prices and graded-card comps, updated daily. Pokémon is priced separately for each of the 9 language versions, and it also covers One Piece, Lorcana and Riftbound (App Store page, 11-06).

The UI is styled like a finance app: a collection value curve, gains and losses, price alerts, and a weekly report pushed every Monday.

The free tier stores up to 300 cards and 15 sealed products, with 10 scans a week. Pro has weekly, monthly and yearly subscriptions, with a 3-day free trial first. Monthly is €4.99 (the example on the official creator page shows this price).

The company COLLEKTIK SAS was registered in Paris this July, with 0 employees. CEO Swann Grenouilloux was born in 2004, and since 2022 has been registered as a sole trader whose activity is "retail of second-hand goods" (pappers.fr). Whether he resold cards before, unverified.

How big it is now

In one line: still just getting started. Reference is a niche category, and a #135 Top Grossing ranking only shows people are paying, not how much. A third-party estimate puts its monthly downloads and monthly revenue both under $5,000 estimated, not verified.

Same idea, already scaled up in France

If you think "European users, euro prices, valuation by card language" is an empty space, you're wrong. In France, Collektik is the latecomer:

Collektik's French ratings are a tenth of PokéItem's and a hundredth of PokéCardex's. Its product adds a Turbo continuous-scan mode and a finance-style interface, but there's no evidence users came for either.

Where users come from: short videos cut from price tables

What really sets it apart from rivals is distribution.

• French account @collektik: started posting Sep 26; by Nov 5 about 120 videos, roughly 920k total views, median about 3,400 (TikTok, 11-06). The first week's videos had no titles, just "Collektik en bio", yet a few reached 30,000 to 70,000 views. From October it switched to fixed templates and posted several times a day: "Three French cards have dropped since July, only one has risen", "21 ETB Elite Trainer boxes, what each set sold for at release versus 2020 to 2023 year by year", "Same card, raw versus PSA 10, 15 times the difference". Every video ends with the same line: "Tu en as une dans ton classeur ?" (Do you have this one in your binder?).
• German account @collektik.de: opened in Oct 26; by Nov 5 it had 29 videos, roughly 130k total views. A Nov 1 video, "All 191 cards, release price → today, only 6 went up", reached 42k views, and the top-liked comment was "Let them keep printing, card prices only bottom out when they do". German captions end with "Gratis · „Collektik" suchen" (free, search Collektik), pointing viewers straight to the store search.
• The timing lines up: the German Free category chart jumped from the sixties to #11-03 in 27; the German rating count was only 10-28 2, and over the next ten days it added 1 per day (App Store).
• Still building: the Spanish account @collektik.es is registered but hasn't posted any videos yet. The same clips are being mirrored to Instagram, YouTube Shorts and Facebook, but individual posts get only a few likes. The official site runs a creator affiliate program: 12% of net revenue split over 12 months, and users with a creator code get a 3-day Pro trial. No well-known creator promotion was found.
• Ads: no ads from it turned up in the Meta Ad Library, and the official site says "aucune publicité, aucun traceur tiers" (no ads, no third-party trackers). Large-scale paid acquisition looks unlikely inferred.

The footage for these videos all comes from its own price database: which cards fell, a whole set's release price compared with today, and how many times raw cards differ from graded ones. The data changes every day, so topics never run out, and switching languages only means swapping in that language's card names and prices. Judging by how often it posts and how uniform the templates are, it's likely semi-automated inferred.

Who's coming and who's complaining

The 5-star reviews focus on "accurate scanning, straight into the collection, and a release calendar you can check". One French review of 10-18 says: "Very useful for collectors, some features are paid, but still great."

The negative reviews are also concentrated, half about the paywall and half about the data:

"Only 300 cards before you have to buy a subscription, otherwise you're out of luck." German store, 2 stars, 10-29 "Happy to see a new app that supports German cards, but even English mid-period cards have no prices..." German store, 1 stars, 10-27 "Prices in the app are wrong 80% of the time, and scanning costs money and doesn't work well." French store, 1 stars, 10-19

The German average is 3.22, the French 4.69. The difference comes down to this: wherever its TikTok accounts go, downloads follow; and if that language's price data isn't filled in, the reputation collapses on the spot.

If it were you

B

I wouldn't build another Pokémon valuation app for France or Germany. Those markets are already crowded, and Collektik itself hasn't got a firm foothold yet. What's really worth taking is its acquisition method: use your own price data to automatically cut short videos every day covering "went up, went down, release price versus today", one account per language. The method is cheap and few people know about it, but every step depends on having reliable price data of your own.

Who it suits: a 1–2 person small team that already has, or can get, market data for some collectible (a trading platform API, a sold-price scraper), can batch-produce vertical video, and ideally is already part of that community. Two routes: one is to switch categories and do sports cards, One Piece, Funko, LEGO or sneakers, which all have price data and release dates; the other is to switch languages and go after Pokémon in Italian, Spanish, Polish and Portuguese, where local price coverage currently looks thin inferred, not checked one by one.

Who it doesn't suit: anyone without a data source who plans to rely on AI estimates (the "prices wrong 80%" reviews show where that ends up); anyone wanting to head-to-head PokéCardex, PokéItem or Collectr in France, Germany or the US; anyone who only wants to build an app and won't post content every day.

How to do it: build the data first, then the app. Pick one category and one language, and pull that language version's sold prices every day. The app only needs three things: scanning, a collection value curve, and price alerts. Don't cap the free tier as tightly as Collektik does (charging after 300 cards already earns one star). Price subscriptions in the €4–5 per month range and offer a trial first.

How to get users: open accounts two or three weeks before launch, 2–3 videos a day, using its few templates for topics: "how much this set has dropped since release", "a whole set's total value, card by card", "raw versus graded, how many times the difference", "what's coming next month". The closing line matters; make people want to check their own binders. Put a link in the profile and write "Free, search XX" in the captions. Get one language working before opening the next account, and fill in that language's price data before each new account goes live.

When to move: the heat from Pokémon's 30 anniversary, the 11-06 new expansion and the Christmas releases will likely run until January 2027 inferred. If you're going to take the Pokémon route in another language, open accounts by mid-December. If you switch categories, follow that category's own release calendar; this window doesn't apply.

Signs you've misread it: ① Collektik's German account keeps posting, but German ratings and chart position fall back before late November, which would mean the content only produced a one-off spike; ② after the Spanish account launched, the Spanish charts didn't move; ③ PokéItem and Cardzia start batch-posting price videos per language and grow faster than it does, which would mean anyone can copy this approach, so being first doesn't help; ④ after the holidays card prices stabilize and "how much it dropped" videos drop to a few hundred views, which would mean it was riding the 30 anniversary price swings, not a method that lasts.
