Ramp Engineer Sam Kronick Says Laminar Took Six Weeks and Runs Every Agentic Product
Summary
Ramp built Laminar, its own agent harness, rather than depending on a single model provider's managed agent API, engineer Sam Kronick says. The v1 took six weeks and now runs every agentic product at Ramp. It stores sessions in PostgreSQL and orchestrates work with Temporal, keeping agents model-agnostic.
Key Points
- Sam Kronick says building in-house keeps Laminar model- and provider-agnostic instead of locking Ramp into one LLM vendor's models.
- Ramp's CTO prints agent traces on paper to expose wasted tool calls, excess turns, and bloated context.
- Laminar decouples agent session state from sandbox lifetimes, provisioning a virtualized computer only when a tool call needs one.
