# Blitzy

> Blitzy builds an autonomous software development platform for enterprises with large existing codebases. It maps architecture and dependencies into a knowledge graph, coordinates AI agents to plan and implement changes, and returns code for human review. Its work spans feature development, legacy modernization, testing, documentation, and security remediation.

- **Founded:** 2023
- **Headquarters:** Cambridge, United States
- **Founders:** Brian Elliott (Co-founder and CEO), Sid Pardeshi (Co-founder and CTO)
- **Products:** Blitzy platform / Blitzy OS, Blitzy Sandbox, PR Review, Chat to Prompt, Enterprise implementation and modernization
- **Notable:** Announced $4.4 million in initial funding upon emerging from stealth in September 2024., Raised a $200 million growth round at a $1.4 billion valuation in May 2026., Reported 84.95% on SWE-Bench Pro Public in June 2026, with Quesma validation described in its announcement; benchmark performance does not establish customer-project outcomes.

## Products & services

- **Blitzy Sandbox** — Free evaluation for eligible organizations on their own code. The current launch article describes up to 1 million lines reverse-engineered and 100,000 lines generated; older September material states 25,000 generated lines.
- **PR Review** — Explains pull-request changes, implementation reasoning, and validation evidence for engineers reviewing AI-generated work. Announced September 28.
- **Chat to Prompt** — Uses codebase context to investigate changes, refine requirements, score build prompts, and prepare an Agent Action Plan. Announced October 13.
- **Enterprise implementation and modernization** — Paid engagements for feature additions, refactoring, documentation, testing, security remediation, and legacy modernization, with deployment choices varying by engagement.
