Our own products

Software we funded and shipped ourselves.

We put our own capital, pods and on-call rota behind these four. They exist because we hit the problem ourselves first, then productised the fix.

Why it matters

No studio should ask you to trust software it has never shipped. The engineers who build these are the engineers we embed with you.

Venture studio portfolio

From our own products to client software ventures.

The exact same senior engineering pods that architected Sparrow, JustInterview.ai, and Aether Voice co-found and build software for funded startups and enterprises.

Start a conversation

Whether it's co-founding a venture from a blank repo, embedding a senior pod, or automating the back office — bring us the architecture problem and we'll tell you honestly whether we're the right team for it.

What you get either way
  • You talk to a senior architect, not an account manager
  • 24-hour response on any scoped request
  • Mutual NDA and IP assignment as standard
