AI-powered tools for everyone who takes careers, learning and development seriously.

We build evidence-backed software and learning systems that help people grow. Quality over volume, always.

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.

Learning in public

Zenko Research

Educational work to understand markets and agentic workflows, in the open. SF4L runs a trading system for its own account and publishes how it is tested and how it performs against one benchmark: holding Bitcoin.

Every hypothesis is written down and hashed into Bitcoin before it is tested, and every verdict is published, pass or fail. The trading logic is deterministic: a language model only turns analysts' prose into data, and a human holds every irreversible switch.

Not investment advice. The system is not open to outside capital.

Background

SF4L combines more than a decade of experience in learning design, AI systems, and organizational transformation. From UNICEF-partnered education programs to enterprise L&D strategy, the focus has stayed the same: helping people grow. Now we are applying that to the job search, because finding the right role should not feel like a full-time job.
