Every call has a name
The founder approves each decision personally. The log shows who decided what, and when.
Agents build in the open
Every change the AI agents make lands in the log: what was built, and what it touched.
Nothing ships unchecked
Speed, accessibility and tests run on every change. A failed gate stops the release.

06Who builds it
The person you pitch to is the person who builds it.
No hand-offs, no bench. The person who scopes your product designs it, builds it with AI agents and answers for it — so there is no gap between what was promised and what ships.
Outstanding work on our full UI/UX redesign and new logo. Dmytro is a clear communicator, accountable, and genuinely committed to quality — the redesign transformed our whole product.
