We're Ooak Data

The promise of AI agents is still unmet in complex, real-world business environments. Our mission is to make it possible for agents to reliably accomplish concrete and useful tasks.

Over the next 6 months, we'll acquire and anonymize 300+ full data ecosystems from real-world companies to become the leader of real business workflow data

This summer we need to build our elite squad to move extremely fast and confirm our leading position on company data.

🤝 Our values

• Trust, the foundation of every relationship, internal and external. We extend it by default and value the ownership that comes with it.
• Ambition, we commit, we move fast, with tenacity and efficiency.
• Collective, team first, low ego.
• Kindness, at the heart of every interaction.

We're building a solid, aligned, and motivated team.
