Compare the four packages

How we think

Serious products, made with the principles of play

Weft Play

Illustrative: a hand sliding a coral triangle across a wireframe sketch, with sticky notes and play shapes nearby

Woven in, not stuck on.

Play woven into the structure from the first sketch, so people stay because they want to. The same craft we learned making our own small game, applied to banks, utilities and health.

Human-sized AI

Illustrative: two pairs of hands cupping a softly glowing mint orb above a navy table scattered with play shapes

Around people, not in place of them.

From a one-day Kindle workshop to shipped products with guardrails designed in. AI is nothing without creativity, and ours comes from years of making things people enjoy.

Owned by the people who do the work

Together we own 71% of Tumbleweft.

Illustrative: four colleagues in a brick-walled studio mapping ideas on a wall of sticky notes

When the studio belongs to the team, the team shows up differently

Through an employee ownership trust. Everyone who works here is a partner. (A fictional figure for a fictional studio.) The people on your project have a stake in it going well long after the launch party.
