Husayn Kassai is the founder and CEO of ollo (Askollo.com), an agentic platform paired with hands-on co-build sprints that turns non-technical teams into AI agent builders. The company grew out of a problem Husayn saw repeatedly: most organisations are too big for generic AI tools yet too small for enterprise implementations, leaving the majority of companies underserved.

Before ollo, Husayn co-founded and led Onfido as CEO, scaling the identity-verification company from $0 to $100M ARR in seven years. Onfido’s 2024 acquisition became the largest UK AI exit since DeepMind in 2014. Building biometric verification for banks taught him that security and utility are not opposing forces – a principle that now shapes how ollo handles sensitive company data.

Based at London’s AI Hub, Husayn writes widely on AI adoption, organisational knowledge, and the startup ecosystem more widely. He holds a BA in Economics and Management from Keble College, Oxford, where he also served as President of Oxford Entrepreneurs.
