How Factorial Built an Agent Across 25+ Products

Factorial is an all-in-one AI platform for business, serving more than 17,000 companies across 9+ markets, and its agent One lives in the center of the product rather than beside it. That means one question can reach across more than 25 products, and every answer has to respect the same permissions as the person asking. Ilya Zayats, CTO at Factorial, shares why the team went looking for a framework in the middle of the spectrum, how their homegrown pieces gave way to native Mastra approaches as both products matured, and where One goes next now that it's live for every Factorial customer.
