About Us

The Anti-Crisis Squad that steps in when others step back.

Who We Are

Senior-only. Crisis-ready. Remote-first.

We are a senior-only team that steps in when timelines slip, teams burn out, or products stall. No juniors. No overhead. Just experienced engineers who ship. Every person on our team has 13–16 years of hands-on engineering experience — and most of those years were spent delivering under pressure for EU, UK, and US clients who couldn't afford to fail.

We're remote-first by design, not by circumstance. We've worked async across timezones for over a decade — which means clear communication, daily visibility, and zero surprises.

The Team

5 people. No bloat. All senior.

We deliberately stay small so every client gets direct access to the engineers doing the actual work.

Our Approach

Three principles we actually live by.

Senior-only

No juniors. Every engineer has 13+ years.

We made a deliberate choice to stay small and senior. Every person on your project has over a decade of real-world shipping experience. You pay for expertise, not for mentoring someone on the job.

Crisis-ready

We join failing projects and turn them around.

Most agencies avoid messy situations. We seek them out. A stalled codebase, a missed deadline, a team that burned out — these are the conditions where we do our best work.

Results-first

We measure success in shipped features, not hours logged.

We don't bill time — we deliver outcomes. Milestones, demos, and working software are what we're accountable to. If it's not shipped, it doesn't count.

By the Numbers

The track record speaks.
