Blitzy has raised $200 million at a $1.4 billion valuation as enterprises look for more autonomous ways to modernize large software systems. The Cambridge-based startup, which builds an autonomous software development platform, said the growth round was led by Northzone, with participation from PSG, Battery Ventures, Liberty Mutual Strategic Ventures, Erie Strategic Ventures, and other investors.
The company said its platform is already being used across dozens of Global 2000 enterprises and is designed to move beyond human-guided copilots or single-agent coding tools. Blitzy’s system reverse engineers existing enterprise environments, builds a dynamic knowledge graph of a company’s codebase, and coordinates thousands of AI agents to complete larger software development projects.
Blitzy said the funding will help expand its research team, scale go-to-market functions, and grow its partnership ecosystem, with a focus on regulated industries such as government, financial services, and insurance. The company has more than doubled its headcount over the past six months.
Co-Founder and CEO Brian Elliott said the financing validates Blitzy’s view that frontier models alone are not enough to solve enterprise software development. “We believed that delivering production-ready code for the enterprise would come from fusing hyperscaled agent orchestration and a system that deeply understands the legacy codebases it is working within,” Elliott said.
The raise comes as companies face pressure to modernize aging systems while improving engineering productivity. Blitzy said its platform can complete months of development work autonomously, including testing and validation, and has driven five-times engineering velocity for some enterprise customers.
