Independent software studio

Thoughtful ideas.Useful software.

We build digital products that bring people closer to what they love. From the next chapter to the next matchday.

The products

Two products, live and growing.

We only build what we would use ourselves, and we stay with it after launch. These are the two products we run today.

The studio · Under the Tree

A name that is a place, not a brand.

Under33 is short for Under the Tree. It is where the good thinking happens: sitting in the shade, unhurried, sketching things that matter. U33 exists to take those sketches seriously — to implement ideas and turn them into software products for the common good. The tree is the studio; the products are what grows in it.

01

Common good

Every product has to make everyday life genuinely better for someone — a fan, a club, a person looking for their next job. If it only makes a dashboard look busier, we don't build it.

02

Craft

We are a small group and we like it that way. Fewer products, built carefully, kept simple, and maintained with the patience of a gardener.

03

Independence

The bohemian part is real. We grow ideas at their own pace, free of hype cycles — under the tree there is no rush, only roots.

How we work

A grove on one side, a build lab on the other.

U33 is how an unhurried idea becomes running software. Three stages, always in this order:

01u33 sit

Under the tree

Every product starts away from a screen: a slow idea, noticed and noted. The shade is where we ask whether it serves anyone at all.

02u33 sketch

Into the hub

The idea moves to the workbench — prototypes, AI agents, quick honest experiments. Most seedlings stop here; the ones that matter keep growing.

03u33 ship

Out to people

What survives becomes a product we run and tend for years — software for the common good, maintained like a garden, not a backlog.
