Blitzy
Also known as: Blitzy OS, Blitzy AI
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 specialised 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. It holds the 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 where it separates from everything else in this lane. It is SOC 2 Type II compliant and ISO 27001 certified with a public trust centre, 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, defence contractors and other organisations with absolute data sovereignty requirements.

In practice
You have a six month modernisation 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 daily refreshed knowledge graph so thousands of agents share one current source of truth rather than each rediscovering context.

| Integrations & Tool CallingIngests an entire codebase and returns compiled repositories and tests, but no integration catalogue, IDE plugin or collaboration tool connectors are documented, which is consistent with the deliberately isolated architecture. 2026-08-05 | Partial |
|---|---|
| Workflow OrchestrationOrchestrates thousands of specialised agents across multiple frontier models to plan, build and validate production code, running uninterrupted for days or weeks on a single submitted specification. Hyperscale agent orchestration is the entire product. 2026-08-05 | Full |
| Knowledge Grounding & RAGReverse engineers the entire codebase into a dynamic knowledge graph that is refreshed daily and acts as a shared, always current source of truth for both engineers and agents, marketed as infinite code context. This is the core differentiator against single agent tools. 2026-08-05 | Full |
| Human Oversight & GuardrailsThe human boundary is designed and stated rather than implied: Blitzy targets roughly 80 percent of a roadmap with a human engineering guide completing the remaining 20 percent, returns a precise scope of what is left, runs multiple QA agents that check each other before delivery, and tells buyers explicitly that their own team should still perform QA and security testing. 2026-08-05 | Full |
| Security, Identity & GovernanceSOC 2 Type II and ISO 27001 across all tiers with a public trust centre, no training on customer code, and code never stored at all with only embeddings retained. The code generation platform is completely isolated with no publicly exposed endpoints, running inbound only within a VPC and never initiating outbound requests, with SAML SSO and encryption in transit and at rest. 2026-08-05 | Full |
| Observability & AuditabilityOutput arrives compiled, end to end tested and accompanied by a precise scope report of remaining work, which is meaningful visibility into results, but no run tracing, agent level audit trail or intermediate execution transparency is documented across a job that may run for weeks. 2026-08-05 | Partial |
| Memory & State PersistenceThe knowledge graph persists as durable shared state across runs and is refreshed daily rather than rebuilt per task, and agent jobs maintain coherent state across days or weeks of continuous execution. 2026-08-05 | Full |
| Deployment & Data ResidencySix deployment shapes documented: cloud, hybrid cloud, VPC, black box VPC, on premises and black box on premises, aimed at organisations with absolute data sovereignty requirements. The widest deployment range found anywhere in this sweep. 2026-08-05 | Full |
| Prebuilt Agents, Templates & PacksThe platform ships thousands of specialised agent roles including dedicated QA agents as prebuilt internal capability, but there is no customer facing template gallery, agent catalogue or reusable pack to select from. 2026-08-05 | Partial |
| Triggers & Channel CoverageWork is initiated by submitting a specification for a batch build; no scheduled runs, event triggers, chat or ticketing invocation surfaces are documented, unlike agents that are tagged in Linear, Slack or GitHub. 2026-08-05 | Partial |
| Model Flexibility & RoutingAgents are orchestrated across multiple top frontier models rather than bound to a single provider, which is genuine multi model routing at the platform level, but no model list, customer facing selection or bring your own key capability is offered. 2026-08-05 | Partial |
| APIs, SDKs & MCP ExtensibilityNo public API, SDK or MCP surface is documented, and this is architectural rather than incidental: the platform explicitly has NO PUBLICLY EXPOSED ENDPOINTS and never initiates outbound requests. The security posture and the extensibility score are the same design decision seen from two sides. 2026-08-05 | Unable to verify |
| Testing, Debugging & OptimizationMultiple QA agents cross check each other's work before any code reaches the customer, output arrives compiled with end to end tests attached, and the platform holds the record score on SWE-Bench Pro, which is an independent public benchmark rather than a vendor claim. 2026-08-05 | Full |
| Browser & Computer UseNo browser control or computer use capability. Agents operate on the codebase within an isolated environment rather than driving external interfaces. 2026-08-05 | Unable to verify |

Pricing
Explore $0; Concept Validation $50,000 over 2 months; Structured Pilot $250,000 over 6 months; Enterprise $500,000+ per year on a 36 month term; Transformation $10M+ per year on a 48 month term. Usage metered at $0.20 per line generated
lines of code generated, plus onboarding volume by tier
What is public
Every tier, term length, onboarding and generation volume, and the per line rate are published, which is rare at this contract size and notably more transparent than most vendors charging a fraction as much.
Billing mechanics
A deliberate two phase model. Evaluation runs through Explore at no cost, Concept Validation at $50,000 for two months delivering a guided proof of concept, or a Structured Pilot at $250,000 for six months deploying into the customer environment with 5 million lines onboarded and 1.25 million lines generated. Deployment then moves to Enterprise at $500,000 or more a year on a 36 month term covering 50 million lines onboarding and 2.5 to 15 million lines of generation with dedicated infrastructure and SAML SSO, or Transformation at $10 million or more a year on a 48 month term adding infinite code context, custom deployment and embedded forward deployed engineers. All tiers carry SOC 2 Type II, ISO 27001 and the no training guarantee.
Cost watchouts
Contract terms are long at 36 and 48 months, and the platform explicitly delivers about 80 percent of scope, so the remaining 20 percent of engineering effort must be budgeted alongside the licence
Variable cost rationale
Cost is metered on lines generated, and an autonomous platform designed to produce millions of lines controls that variable more than the buyer does, with generation capacity at the Enterprise tier spanning a sixfold range from 2.5 to 15 million lines.
Additional watchouts
This is a large enterprise commitment, with the smallest real deployment starting at half a million dollars a year on a three year term. Blitzy also states plainly that it delivers around 80 percent of a roadmap and that customers should still run their own QA and security testing, so the internal engineering cost does not fall to zero.

Commercial notes
The per line unit at $0.20 is the most legible pricing metric encountered in the coding agent lane, and the staged evaluation path lets a buyer prove return before committing to a multi year contract, which is unusual at this deal size. It also makes the economics comparable: a million generated lines is $200,000 of usage regardless of how many agents produced it.
Key ambiguities
The relationship between the per line rate and the tier fees is not spelled out, specifically whether the $0.20 per line is charged on top of the annual figure or drawn down against it. Generation capacity ranges are also wide, from 2.5 to 15 million lines at the Enterprise tier.
Missing data
How the per line rate interacts with the annual tier fee, what happens above the generation ceiling, and pricing for the black box and on premises deployment shapes.
