Pay-i is now Ascerta. Our name grew with our mission: giving enterprises certainty at every stage of AI transformation.

Built by People Who Ran AI at Scale

We managed AI economics for one of the world’s largest enterprises. We built Ascerta because every enterprise would soon need the same thing.

Our Mission

The Nature of the AI Enterprise

Ascerta brings clarity to AI strategy. We built this company on a simple conviction: AI is transforming the nature of work, and companies that fully understand how to integrate it into their workforce will manage that transformation best.

Leaders who can see what their AI produces build on it with confidence. They move decisively where others hesitate. They pull ahead and stay ahead, again and again. We exist to put them in that position.
