About the Company

Our client is building an enterprise-grade AI operating system. It post-trains open-source models on a customer's own data, integrates across the enterprise stack (email, Slack, ERPs, CRMs), and lets employees and executives take action through natural language — all deployed in the customer's own cloud, so company data never leaves their servers and model weights become corporate assets over time. It reports $5M ARR in Q1 across 50+ customers, with preemptive Series A interest.
