About Mastra

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, GitHub.

Why This Role

Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.

What You'd Sell

  • Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs)
  • Agent Builder (agents without code)
  • Concierge (embedded Mastra engineers working alongside customer teams)

Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.

You Have

  • Closed full-cycle deals in dev tools, OSS, infra, or AI.
  • Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution.
  • Founder or founder mentality.
  • Comfort with a product that ships something new every week.
