A single person in Canada sells a $50 replacement board that fits inside a Casio F91W, adding Bluetooth, step tracking, time zone sync, RGB LED, and even blackjack. The project is small enough that the creator ships every order on Fridays — and it's already got Andrew hooked.

The conversation turns technical when the hosts investigate whether flipping the Fitbit Air to the underside of the wrist actually works for fitness tracking. Marques pulls up an AI overview to explain the mechanics: the optical sensor needs a tight light seal against the skin, and the tendons running from the forearm to the fingers constantly flex and introduce light leak. Adam notes that bicep straps gain popularity precisely because muscle tissue provides a cleaner optical read. David recalls Des Fitz's review noting that the Fitbit Air's thin profile already risks light leak at its edges compared to the wider Whoop.
Game apps keep users engaged long enough for ads to pay off. Tool apps don't — so if you're building a utility, ads are almost always the wrong call and subscriptions are your only real lever.
Inside SEO Bot, a single button labelled 'Boost My Domain Rating' routes users directly to Listing Bot. That one interaction converts a user of one tool into a user of two — without any marketing cost.
Directory listings are a powerful but underrated growth channel — but only if your product is genuinely interesting enough to earn the click. AI products have a natural advantage here because they're easy to package in a compelling, clickable way.
The fastest path to Twitter growth isn't volume — it's forming sharp opinions about how the platform works and sharing them immediately. People cluster around those who understand the rules and say so out loud.
Sam had no coding knowledge, so he used ChatGPT voice mode to generate his entire codebase and copy-pasted it into Notepad. A friend later introduced him to Cursor, and he never looked back.
Copy days of Discord chat history, paste it into ChatGPT, and ask it to list recurring pain points. The ones that come up most often are your best product bets.
Sam's top advice: when prompting Cursor, tell it to architect code for 100,000 users from day one. The AI changes its approach, building scalable frameworks instead of brittle one-user code.
With AI coding tools like Cursor, Bhanu replicates an existing free tool for a new keyword in under 5 minutes. What used to be a multi-day build is now a lunch-break task.
Ahrefs, SiteGPT, Cal.com, PostHog, Datafast, Sibyl AI, Bento, Feather, Featurepace, Mintlify, Cloud Code, ChartMogul — Bhanu runs his entire business solo with these 12 tools.
