Venture Development Studio
by builders, for builders.

For years we have designed and shipped apps, web platforms and systems for companies - and built our own solutions along the way. Today, with development more accessible than ever, we also join early-stage ventures as hands-on operators: experience first, a smaller initial investment when it makes sense, one goal - grow or exit.

Let's build something

One studio, three ways in.

The same senior team behind every mode.

Build for clients

Apps, web platforms and systems for companies that need senior engineering, design and product thinking in one team.

Make our own

We design, build and run studio products, and deliver them to companies. Skin in the game, not just billable hours.

Back early ventures

We join ventures at the earliest stage as operating co-founders - and back them with a smaller initial investment when it fits.

Where we go deep.

Narrow focus across everything we build, make and back.

.founders = start here

Building early in our space?

We are not a fund. We join as operating co-founders: product, engineering, design and go-to-market, plus a smaller initial investment when it makes sense. What a term sheet can't give you, a decade of shipping can.
