The promise of AI agents is still unmet in complex, real-world business environments. Ooak Data's mission is to make it possible for agents to reliably accomplish concrete and useful tasks by building Alexandria, the world's largest library of real-world business workflow datasets. Over the next 6 months, the team will acquire and anonymize 300+ full data ecosystems from real-world companies to become the leader in real business workflow data and launch a data research lab in early 2027. This summer, they are building an elite squad to move fast and confirm their leading position on company data.
