Agents that own the ticket.
Assign a ticket and Build plans the change, writes the code, runs the tests, and opens the pull request — then stays around to answer your reviewer.
Build-2 is generally available
Software that builds itself.
Build is the autonomous engineering agent that plans, codes, reviews, and ships production software — end to end, in your stack, under your control.

Product
Four agents. One pipeline.
Build is a system of specialized agents that hand off to each other — planning, implementing, verifying, and shipping as a single unit.
Review before humans do.
A review agent watches every branch: flags risky diffs, suggests patches, and blocks regressions before CI burns its first hour.
Mission control is your terminal.
The build CLI runs agents locally with your real tools, real environment, and real secrets — with a full audit trail of every command.
Sandboxed, scaled, yours.
Every run executes in an isolated VM wired to your repo, your policies, and your keys. VPC peering and on-prem runners included.
Workflow
From ticket to pull request.
One command. No context-switching, no babysitting, no stale branches.

01
Describe
Paste a ticket or describe the outcome in plain language. Build reads the codebase before it writes a line.
02
Delegate
The plan executes across sandboxed environments while you keep working. Watch progress or walk away.
03
Ship
Review the diff, merge the pull request, and Build watches the deploy. Rollback is one command.
Benchmarks
Measured, not marketed.
Every release is gated on the same public harnesses our competitors cite. Same scaffold, same tests, temperature zero.

Yours stays yours.
Built for the teams whose code is the business. Compliance is a checkbox, not a conversation.

Audited annually. Report available under NDA.
SSO & SCIM
SAML, OIDC, and automated provisioning out of the box.
VPC & on-prem
Run agents inside your perimeter with self-hosted runners.
Zero retention
Your code is never trained on. Encrypted in transit and at rest.
“Build closed 340 tickets last quarter. My seniors spend their time on architecture — not on grinding through scaffolding.”
Pricing
Priced per seat. Not per prompt.
Every plan includes the full agent pipeline. Upgrade when the team grows, not when the meter does.
