Jason Petitfourg — AI Product Builder
I turn emerging AI infrastructure opportunities into working products, integrations, and verifiable proof systems.
Jason is the founder of Prove Before Act, the accountability pattern for autonomous agents: prove WHY before acting, then prove WHAT happened.
One coherent story
- The founder: Jason builds and ships AI products and agent workflows.
- The product: Prove Before Act creates an accountable, independently verifiable record around consequential agent actions.
- The evidence: public proof IDs and blockchain transaction URLs let people and agents verify the result.
Built in production
The public reference agent uses the same proof workflow available to other builders. The historical xproof_agent_verify name is a legacy compatibility identifier, not a separate product brand.
