What we do

AI product development

We design and build AI-native products end to end, from matching engines and scoring systems to open agent protocols. Kitsuno is the proof: a full platform conceived, designed, and shipped in five weeks, with Claude as engineering partner.

Learning & development

More than a decade designing how people learn. We build digital learning ecosystems, advise on AI-enhanced education, and help institutions move to competency-based frameworks. Clients have ranged from UNICEF partners to Swiss universities.

Organizational transformation

We help organizations evolve their L&D strategy and adopt AI with intent. Digital transformation and systems change grounded in real practice, not slideware.

Flagship products

Kitsuno

An intelligent job search platform that finds, scores, and matches opportunities based on your actual skills and experience, then writes tailored applications for you. No spray and pray. Evidence-backed, quality over volume.

Kitsuno is also agentic at its core. Through the Kitsuno Handshake, an open agent-to-agent protocol, a candidate's agent and an employer's negotiate a match through staged, consent-first disclosure. The spec is public and Apache 2.0.

Yako

A procurement intelligence platform for organisations that sell to the public sector. Yako reads open tenders, grants and consultancy calls across Europe every night, in every language it finds them, and matches them to your organisation's profile. You get a short list of what you could actually win, each with the reason shown, and a saved search keeps watching after that. Built in Europe, GDPR by design, consent-first like everything we make.
