Built by someone who's done the work.
I'm Yorik Tisseau, founder of Ignis. For 17 years I've worked on the commercial side of complex energy and infrastructure projects. I started as a project engineer and became a Bid Director, running tenders, supplier negotiations and the path to financial close.

Why Ignis
Good teams shouldn't rebuild every deal from scratch.
On every project I watched good teams rebuild the last one. They spent their weeks reconciling versions instead of negotiating, and found the gaps late. I started Ignis to change that: senior commercial judgement plus AI agents that take on the production, so teams can close more projects, faster.
What I bring
“Technology should strengthen commercial judgement, not replace the name on the commitment.”
