Autonomous enterprise software platform orchestrating thousands of agents against a knowledge graph of your codebase, running for days to return compiled and tested code, deployable six ways including black box on premises.

Blitzy is an autonomous software development platform built for large enterprise codebases, founded in 2023 at the Harvard Innovation Lab by Brian Elliott, a former US Army Ranger with West Point and Harvard Business School behind him, and Sid Pardeshi, an ex NVIDIA engineer holding 27 patents in generative AI. It raised $200 million at a $1.4 billion valuation in 2026 in a round led by Northzone.

The architecture is the opposite of a coding copilot. Blitzy reverse engineers an entire codebase into a dynamic, daily refreshed knowledge graph that serves as a shared source of truth for humans and agents alike, then orchestrates thousands of specialized agents across multiple frontier models to plan, build and validate production code. A run is submitted as a specification rather than a prompt, and the platform works uninterrupted for days or weeks before returning compiled code, end to end tests and a precise scope of what remains. The company reports a record score on SWE-Bench Pro.

The delivery model is explicit about its own boundary, which is unusual and worth taking seriously. Blitzy targets roughly 80 percent of a roadmap or new product and states plainly that a human engineering guide completes the remaining 20 percent needed for production. Multiple QA agents check each other's work before any code reaches the customer, and the company still tells buyers their own team should perform QA and security testing. That is a vendor describing the limits of its autonomy rather than obscuring them.

Security and deployment are the core of its pitch. It is SOC 2 Type II compliant and ISO 27001 certified with a public trust center, never trains on customer code, and never stores the code at all, retaining only embeddings. The code generation platform is completely isolated with no publicly exposed endpoints, and runs as an inbound only VPC based system that never initiates outbound requests. Six deployment shapes are offered: cloud, hybrid cloud, VPC, black box VPC, on premises and black box on premises, aimed squarely at banks, defense contractors and other organizations with absolute data sovereignty requirements.

Integrations

Deliberately narrow by design. The platform ingests an entire enterprise codebase, from one million to more than 100 million lines, and returns a compiled repository with end-to-end tests and a scope report. No integration catalog, IDE plugin, source control connector, ticketing, chat, CI or MCP connection is documented, and this follows from the architecture rather than being an omission: the code generation platform has no publicly exposed endpoints, runs inbound-only within a VPC and never initiates outbound requests. Models are orchestrated internally across Google, Anthropic and OpenAI, invoked more than 100,000 times per run across over 3,000 specialized agents, with no customer-facing model selection.

In practice

You have a six month modernization of a legacy system and no appetite to staff it. Blitzy runs uninterrupted for days or weeks and returns compiled, tested code plus a precise scope of what your team still has to finish.

Your IP cannot leave your infrastructure under any circumstances. Black box on premises deployment, embeddings only storage and an inbound only architecture with no public endpoints are built for exactly that constraint.

Single agent tools stall on a codebase this size. Blitzy reverse engineers the whole repository into a knowledge graph it improves with every merge, so thousands of agents work from the same understanding of your code.

Pricing

Reverse Engineer free up to 100,000 lines; Proof of Concept $50,000 over 2 months; Structured Pilot $250,000 over 6 months; Commercial a typical $500,000 a year; usage at $0.10 per line onboarded and $0.20 per line generated

Lines of code: $0.10 per line onboarded for reverse engineering and $0.20 per line generated, within tier volumes.

Free tierTrial available

What is public

Every tier, term, included volume and per line rate is published: Reverse Engineer free up to 100,000 lines, Proof of Concept $50,000 over two months, Structured Pilot $250,000 over six months with 5 million lines onboarded and 1.25 million generated, Commercial at a typical $500,000 a year with the first 20 million lines onboarded, Enterprise at a typical $5 million and Transformation at a typical $50 million a year.

Billing mechanics

A staged model: evaluation through Reverse Engineer, Proof of Concept or Structured Pilot, then an annual Commercial, Enterprise or Transformation deployment. Every tier uses the same rates, $0.10 per line onboarded and $0.20 per line generated, with the annual figures given as typical investment.

Cost watchouts

Generation is metered per line on top of onboarding, and the customer's engineers still own final validation before production.

Variable cost rationale

Cost is metered on lines onboarded and generated, and an autonomous platform built to produce millions of lines drives that volume.

Additional watchouts

Deployment tiers start at a typical $500,000 a year, and the customer's engineers approve the specification and keep final validation before production, so internal engineering cost does not fall to zero.

Overage / add-ons

Beyond included volumes, onboarding is billed at $0.10 per line and generation at $0.20 per line.

Sales call required

Mixed (some tiers require a call)

Free / trial

Reverse Engineer tier at no cost: complete codebase reverse engineering and understanding for up to 100,000 lines.

Lowest paid plan

Proof of Concept at $50,000 for a two month term.

Commercial notes

The staged evaluation path lets a buyer test the platform on its own code before an annual deployment, and the per line rates tie usage cost to the volume of code onboarded and generated.

Key ambiguities

How the per line charges relate to the typical annual investment figures is not spelled out.

Missing data

How per line charges combine with the annual figures, and pricing for the black box and on premises deployment shapes.
