Design concept by Goat Scale · Tumbleweft is a fictional studio. This is not a real company: no projects, enquiries or applications are taken.

Human-sized AI

AI built around people, not in place of them.

AI is nothing without creativity. We bring the habits of making products people return to, and apply them to the models, so what ships is useful, explainable and yours.

Three ways in

Start as small as a day, go as far as a product

  • 1 day

    Kindle

    A workshop that takes your team from AI anxiety to a shortlist of ideas worth testing.

  • 2–3 weeks

    Sketch

    Rapid exploration: prototypes real people can react to, and a view on what is worth building.

  • 4+ weeks

    Ship

    Design and build an AI feature or product end to end, with the guardrails to ship it responsibly.

Principles

What every AI feature we ship has to be

Four tests. If an idea fails one, it is not ready, however impressive the demo.

  • Adaptive

    It learns the person, not the other way round.

  • Explainable

    People can see why it did what it did.

  • Focused

    It does one job well before it does three.

  • Responsible

    Guardrails are designed in, not bolted on.

Capabilities

The technical side, in plain words

The team that designs the experience also builds it, so the model choice, the retrieval layer and the guardrails are product decisions, not someone else's problem.

  • Retrieval-augmented generation (RAG)
  • Agentic workflow design
  • Guardrails and evaluation
  • On-device models
