Issue 1 | A trivia game, a custom song and a Wikipedia card deck: last month's 3 fastest-growing sites
The 3 listed sites with the largest gain in checkout visits from two months ago to last month Two are browser games lifted by streamers and short videos; one is a gift shop running on paid ads. For each: how the first users arrived, and how the flywheel turns now. Numbers are Similarweb-estimated checkout visits, not revenue.
A solo-made daily trivia game where rarer answers score higher. 1,925 checkout visits three months ago, 652K last month

How the first users arrived
Launched mid-three months ago by a solo developer going by kp, who describes himself on the site as a 22-year-old US computer science graduate.
We found no evidence of where the first 1,000 users came from. There was no official Product Hunt or Hacker News launch. Speculation: a TikTok clip or a Reddit post by the maker or an early player.
From two months ago, a group of TikTok and Instagram creators who record daily puzzle games picked it up as daily material (mikaylapuzzles, puzzletank and others). Checkout visits went from 1,925 three months ago to 152K two months ago
Around September 24, ohnePixel, a top CS2 streamer, recorded an episode. It was already growing by then, so he amplified it rather than started it.
The flywheel now
The scoring rule is the video script: “can I find the rarest answer?” fits a 15-second clip by design.
Everyone gets the same 7 questions each day: creators get fresh material daily, viewers play the same set, then ask creators in the comments to keep going.
Friends compare depth: scores convert to real ocean depth, and friends compete on who dives deeper, so players send each other the day's questions.
Third-party guide sites catch the searches: from late two months ago, “today's answers” sites and clones appeared, capturing queries like “krillion answers” and sending awareness back to the main site.
Revenue: ads, one-time themed pack unlocks (any pack removes ads site-wide), and a merch store.
What you can copy
In a daily puzzle, a scoring rule that produces a moment worth filming does more than a share button.
One global puzzle per day is supply for creators: a new set every day is a new video every day.
59% of its traffic is direct and 90% of its search traffic is brand terms, so growth comes from players returning daily and word of mouth, not SEO.
A French custom-song gift shop. Zero checkout visits through two months ago, 292K last month It runs on paid ads; it is here because it grew the most and because the playbook is easy to copy.

How the first users arrived
Operated by HH Ecom Limited, a Hong Kong company, on Shopify. It calls itself “France's No. 1 custom song” and lists a French phone number.
The site went up in May 2026, just ahead of French Mother's Day at the end of May.
There is no launch story. Meta, TikTok and Reddit ad pixels are installed and organic search is about 2% of traffic. The first users were almost certainly bought through Facebook and Instagram ads (speculation, but the evidence lines up).
The site claims coverage in Le Monde, BFM TV and others. We could not find those articles.
The flywheel now
The ad formula: an invented French singer persona (“Your performer: Antoine, 46, Montpellier”), AI-generated French family scenes, and an emotional hook like “she cried at the first note”.
The deliverable carries the brand: the song arrives as a private listening page on votremelodie.com. Recipients post it to Facebook, the link card shows the domain, and their friends see it too.
Reviews as trust and traffic: 2,592 reviews on Trustpilot, and Similarweb shows Trustpilot itself sending visitors.
Email remarketing is the top channel, paid social second.
Copy by language: an Italian version and Italian ads already exist, with the singer renamed Marco Bellini.
What you can copy
When an emotional gift is delivered as a branded link, every order gets shared once more by the recipient.
One store template plus localized persona ads can be cloned one language at a time.
The risks, plainly: growth depends entirely on ads, so margin depends on ad costs; invented personas and unverified press claims carry consumer-protection risk in markets like France.
A French browser card game where every card is a Wikipedia article. About 14K checkout visits two months ago, about 198K last month

How the first users arrived
The domain was registered on 2026-03-19. The maker is reportedly Naïm Ouellet, an indie developer in Quebec (one source only); the team is now 2 people.
After a quiet March launch it grew to about 10K daily users by two months ago We could not trace the channel for that stretch. Speculation: word of mouth in Quebec and France, plus friend-only battles that push players to bring friends.
During the ZEvent charity stream marathon on September 4–7, major French streamers (press names Domingo and Anyme) played it live. Within days it hit about 200K daily users and the servers buckled.
In late last month Presse-citron, jeuxvideo.com, Switzerland's 24 heures and others covered it, bringing a second wave from the press.
The flywheel now
Opening packs is fun to watch: rarity comes from the article's page views, so “who did you pull?” is a built-in talking point for streams and screenshots.
Battles are friends-only: to play quiz battles you have to bring friends in.
Trading and auctions need other people: more players means a more liquid market and more valuable cards.
Guilds chase leaderboards: guild members recruit on their own.
Controversy brings more coverage: addiction concerns and “don't give this to students” warnings triggered another round of articles.
Revenue: Pro at CA$9.99 a month, and 2,500 in-game coins for CA$4.99.
What you can copy
A product whose core moment is fun to watch is ready-made for streamers. One stream turned a slow 10K daily users into 200K.
Only multiplayer mechanics turn viewers into recruiters: friend battles, trading and guilds all push players to bring friends.
Using public content (Wikipedia) as the card pool costs nothing and comes with its own “who is this card?” conversation.
