Product.ai is building the verification layer for AI commerce. We are not a startup pitch. We are a profitable company that has been verifying commerce data at scale for over a decade. No venture capital. No board. 100% founder-owned. Product.ai operates more like a special forces team than a traditional company. Every team member is an Axiomatic Engineer — an autonomous operator who extracts their mission from the company strategy, not from a manager's task list. We do not hire for well-roundedness. We hire for spikes: the innate talents that produce non-linear output when amplified by the right systems.
