About

Building products in the open, with AI.

I'm Sergii Bilak, Lead Developer — I head up the engineering behind everything here. The Be family didn't come from a whiteboard; each tool fell out of actually shipping a portfolio of apps, then got sharpened into something other developers can use.

The throughline across everything: ship real things, show how, and let AI carry the repetitive weight.

The team

Backed by a team of developers, designers, and marketers.
