Autonomous software development startup Blitzy Inc. said today it has raised $200 million in new funding on a valuation of $1.4 billion to expand its enterprise coding platform.

The company was founded in 2023 by Brian Elliott, a serial entrepreneur and former Army Ranger, and Sid Pardeshi, an Nvidia Corp. master inventor who holds more than 27 patents covering neural networks and image generation. It sells what it calls an autonomous software development platform aimed at large enterprises wrestling with sprawling legacy codebases.

Blitzy argues that frontier large language models alone cannot deliver production-ready code at enterprise scale. Instead, its platform reverse-engineers existing environments and builds a dynamic knowledge graph of an enterprise codebase. Then it uses an orchestration layer to coordinate thousands of agents in parallel for days or weeks of uninterrupted inference, the process of running the models to produce results.

The company’s system is designed to handle codebases ranging from 1 million to more than 100 million lines and can call on artificial intelligence models from Google LLC, Anthropic PBC and OpenAI Group PBC more than 100,000 times during a single run.

Blitzy says its approach delivers months of completed software development work, including automated testing and validation. It says it has driven a fivefold improvement in engineering velocity for some customers. The platform is now in use across dozens of Global 2000 enterprises in 10 industries.

The company also points to independent benchmark results to support its claims. It scored 66.5% on SWE-Bench Pro, a coding benchmark used to compare autonomous development tools, which it claims surpasses the latest releases from other major incumbents.

“This financing is strong validation of our platform and underscores the pressing need for a more autonomous and rigorous approach to autonomous software development in the enterprise,” Chief Executive Brian Elliott said in a statement. “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.”

Blitzy has more than doubled its headcount over the past six months and plans to use the new capital to expand its research team and scale up its go-to-market operations. The company said it will also push deeper into regulated sectors, including government, financial services and insurance, where modernization of older systems is a growing priority.

The funding round was led by Northzone. New backers PSG, Battery Ventures LP, Jump Capital, Morgan Creek Digital Assets and Defiant joined existing investors Flybridge, Link Ventures, NFX, Picus Capital GmbH and Venture Guides. Strategic investments came from Liberty Mutual Strategic Ventures, Erie Strategic Ventures and BAL Ventures.

“Blitzy has created a truly paradigm-shifting product in one of the largest markets in the world: autonomous AI coding,” said Sanjot Malhi, a partner at Northzone. “They have meaningfully shifted outcomes for several Fortune 500 enterprises and are well on their way to creating a category-defining platform.”
