ThirdLayer

four weeks before YC demo day, we killed what we'd been building. it had a 50% CMO response rate, but we couldn’t stop thinking about an idea that nobody had a name for yet…

10,000+ downloads later, that idea is Dex.

If your writing still sounds like AI slop, the problem isn’t the tool. It's you.

The best founders have trained their AI on exactly how they write. Down to when to use "!!" vs ":)" and different email structures and cal links for hiring vs sales.

Dex builds this automatically from your actual context -- your relationships, history, workflows, and the thousands of decisions across your apps.

Comment "write-like-me" for the prompt.

Telegram integration is live! If you're in crypto, trading, or just running serious comms through Telegram, you know that managing chats used to be completely unscalable.

Now, Dex has 35 tools that allow it to read, search, and act on Telegram. No more leads going cold, questions getting buried, and context getting lost in an endless scroll of messages.
