I ship the code and I do the talking. Nine years, five companies, 250,000 users. Most of them are gone now.

The host

David

Engineer and founder. Nine years of building, most of it my own companies, in crypto since 2023.

I build the whole thing: the backend, the frontend, the infrastructure it runs on, and the pitch for it. I work best next to people who have the market and the audience. I build it, they sell it, we both own it.

What I care about: software that is simple, clear, fast, secure and beautiful. Most of it manages one.

Right now: Hardcut, a control room for live shows, and the agents I build everything else with.

Twelve months across China, Hong Kong and Japan. Studying Mandarin.

The graveyard

Five things that reached real numbers and then stopped

Most of that is gone. Now: Hardcut, Ishizue, and the agents I build everything else with.

IslandDAO

First place, IslandDAO

IslandHack V4, June 2026. A month on an island, 33 pitches on demo day, three winners.

The pitch, two minutes
The demo, three minutes
What we built

Proof of Exploit, an automated security audit for Solana contracts. You hand it a contract. It runs the full check, AI alongside the classic security tools, and when it finds something it goes all the way: it builds the exploit and runs it, so every finding comes back verified instead of suspected.

Why

Manual audits are very good, and very expensive: a proper one can cost upwards of $50,000. First-time founders and small teams do not have that, so most of them ship without one.

The gap

Nothing sat between shipping unaudited and paying $50,000. The pitch was the first step up: $300 for a one-time verdict.

After

Three of us came to the island separately and met there. After the hackathon the other two carried on building the product. They have since moved away from the original idea and built a conventional audit firm with tooling to help it. I am not part of it.

If you’re building something, I want to hear about it. I read DMs.
