San Francisco-based Sentra raised $5 million in a Seed round led by a16z speedrun and Together Fund, with participation from Precursor Ventures and Inovia Capital.
Led by CEO Jae Gwan Park, Sentra addresses “context decay”—the loss of operational knowledge as teams scale beyond the founder stage. The platform automates decision logs and synthesizes the rationale behind workflows, preventing redundant builds across cross-functional teams. This effort to maintain high-fidelity institutional memory mirrors the explainability frameworks seen in Alaffia’s healthcare auditing stack.
Market Signal
- The Scaling Alpha: Context decay is a primary driver of operational waste in hyper-growth firms. By capturing the “why” behind decisions rather than just the “what,” Sentra transforms tribal knowledge into a dynamic, searchable asset that accelerates onboarding and execution.
- High-Fidelity Backing: Participation from Gokul Rajaram and Siqi Chen, combined with a16z speedrun’s lead, signals strong conviction in the “Productivity Infrastructure” category as firms look for alternatives to static, manual documentation.
- The Behavioral Friction: A primary execution hurdle remains the “Signal-to-Noise” ratio; to maintain trust, the platform must successfully distinguish between ephemeral chat chatter and durable strategic logic without adding administrative burden to the user.
