Summary
👤
Senior🎓
Top SchoolGuillaume Crespel is an entrepreneurial software leader and founder with 10 years of experience building full‑stack SaaS products and technical teams from the ground up. As CEO of Kojimo and co‑founder of uni rakun he blends hands‑on development (React, TypeScript, Node) with product vision, data pipelines and go‑to‑market execution to simplify complex processes like real‑estate transactions. He has a track record of shipping pragmatic, secure architectures—often in regulated or hardware‑adjacent contexts—from Decathlon’s global POS to an OCR/AI pipeline for agricultural finance. Comfortable switching between coding, recruiting and customer discovery, he translates user needs into maintainable systems and measurable business outcomes. Based in Nantes, he pairs a pragmatic engineering style with long‑term thinking and a knack for making data actionable for non‑technical users. Notably, his background includes training engineers and bootstrapping teams who can run products autonomously.
