Process
Get an instant price estimate, whether you're building a new feature or need ongoing maintenance.
We give you a custom delivery plan with a refined scope and price on a 15-minute call.
Our AI agents work directly in your workflow, opening PRs in your repo, writing tests, and closing out tickets.
A dedicated human engineer reviews agent output, handles edge cases, and keeps you updated via Slack.
You get merged code, passing tests, documentation, and a clean handoff for everything that ships.
Agents run 24/7 in your repo. You go home, they keep shipping. Wake up to merged PRs, not standups.
Tests included. Your conventions followed. CI green before a human ever looks at it.
A senior engineer reviews every PR. Slack updates, not status meetings.
Everything ships through your PRs. Nothing leaves your repo. No lock-in, no surprises.
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.
