TypingMind

What they built

TypingMind is a better front door to AI chat. Instead of being locked into one company's app, you bring your own API keys and talk to ChatGPT, Claude and other models from a single clean interface, with saved prompts, folders, plugins and team features. Tony Dinh spotted that a lot of people wanted more control than the official apps give them, and were happy to pay once for a tool they own rather than rent yet another subscription.

How they did it

Tony builds in public. He ships fast, posts screenshots and revenue updates as he goes, and lets a growing audience pull the product forward. TypingMind started as a personal-license product, a one-time purchase that spread by word of mouth, then grew a B2B Team plan once companies started using it internally. That B2B plan now drives more than half the money, which is the quiet lesson: consumer tools often find their real margin selling to teams.

The numbers

In his October 2025 newsletter, Tony reported TypingMind running at roughly $130K to $160K a month, past $1M a year, with the B2B Team plan now more than half of revenue (source). He also sells DevUtils, an offline macOS toolkit for developers, alongside it. These are founder-reported figures, so treat them as claimed.

What to take from it: you do not have to invent a new model to win. Wrap an existing one in a better experience, sell a license people own, then follow the demand into team plans where the real budget lives.
