Process

How it works

01

Tell us what you need

Tickets, PRDs, a Loom — whatever you have. We take it from here.

02

We build a custom plan

Timeline. Acceptance criteria. Price. Delivered in days, not weeks.

03

Agents integrate and ship

PRs land in your repo around the clock. Tests included.

04

Expert support guides the work

A senior lead owns the outcome. Slack updates, not surprises.

05

Your backlog clears out

Merged code. Passing tests. Clean handoff. Done.

Powered by the a9s platform.

Autonomous execution

Our agents integrate directly with your repo. They clone, branch, code, test, and open PRs — just like a senior engineer, but they never sleep.

Frontier models

Powered by the latest and most capable AI models for maximum reasoning and code quality.

Human leads

Senior engineers review every line of code before it lands. Agents execute — humans ensure quality.

encryptedisolated

Enterprise security

Secure compute environments and private model instances. Your code stays in your infrastructure. Your IP stays yours.

FAQ

Dev shops sell you hours and a rotating bench. We use fully autonomous AI agents that work 24/7, supervised by US-based senior engineers — no timezone gaps, no language barriers, no ramp time. You get shipped code, not billable hours.

We plug into your existing tools — GitHub, GitLab, Linear, Jira, Slack, whatever you use. Onboarding takes days, not weeks. Work lands as PRs in your repo following your conventions and CI.

Think of us as your 10x teammate that never needs managing. One person to review PRs and answer the occasional question. We handle everything else — you just approve and merge.

Pretty much anything your engineers do — new features, integrations, bug fixes, migrations, test coverage, internal tools. Both one-off projects and ongoing work. If it lives in a codebase, we can ship it.

Your code stays in your infrastructure. We work through your existing access controls, and all work lands via PRs your team reviews. Nothing leaves your repo without your approval.

Those are tools for your engineers — they still need someone driving. We're the whole operation: agents that run autonomously 24/7, a human lead who owns quality, and shipped work your team just reviews and merges. No seats, no prompting, no babysitting.

Scoped engagements or ongoing delivery lanes. We'll figure out the right structure on a call based on what you need.
