Career
Bhagwat's earlier career included a role as Chief Financial Officer of Blueseed, a venture that aimed to create a floating startup community near Silicon Valley as an experiment in seasteading.[1]
He subsequently co-founded Gatsby, a platform that became widely adopted for building websites using modern JavaScript tooling. Gatsby raised $15 million in a Series A round led by CRV in September 2019.[2] According to Crunchbase, Bhagwat held the title of Co-Founder and Chief Strategy Officer at Gatsby and is based in the San Francisco Bay Area.
Bhagwat went on to found Mastra, an open-source, all-in-one TypeScript framework designed for building AI agents and AI-powered applications. Mastra provides developers with tools for creating agents, workflows, retrieval-augmented generation (RAG), memory management, tool integration, and support for the Model Context Protocol (MCP). The framework includes a local development server and a developer studio for iterating on and visualizing agents and workflows. It also offers observability and evaluation features intended to help developers tune agent performance toward human-level accuracy.[3]
Mastra has received attention in the technology press. The New Stack described it as empowering web developers to build AI agents in TypeScript,[4] while VentureBeat reported on the project's "observational memory" feature, which the publication noted could reduce AI agent costs by a factor of ten and outperform RAG on long-context benchmarks.[5]
