Why work with us

We're not consultants who talk—we're developers who ship. When Autobutler's costs hit 3M DKK annually, we rebuilt their infrastructure and cut it by over 60%. When UNOIT needed to serve every Danish citizen, we architected a system that scaled to 2M+ users and later sold to EG.

Most agencies give you junior developers managed by someone who hasn't coded in years. We stay close to the code. Our team has been through the scaling pain, the cost blowouts, and the 3am production incidents. We know Rails deeply because we've been shipping with it since 2014.

What we do

Three ways we can help

We focus on what we're exceptionally good at.

→ Concept to MVP

We'll build your MVP in one week

Have an idea you want to validate with real users? We'll scope it ruthlessly, build it with Rails, and deploy it to production. This works when you have one clear workflow you want to test.

Day 1: We scope to exactly one user flow
Days 2-6: We build it with Rails, PostgreSQL, and modern tooling
Day 7: Live on production, ready for real users

Recent example: competitor email monitoring tool. Built in 7 days, three paying customers by day 15.

How we work

Straightforward process, clear communication

No estimates, no sprints, no ceremony. You tell us what needs building, we scope it, build it, and ship it. Regular updates in Slack, working software every week.

Our core stack

Ruby on Rails, PostgreSQL, Redis, Hotwire. We deploy to Heroku or Render unless you need something specific. We use GitHub for code, Sentry for errors, and modern monitoring tools for performance.

That said, we're pragmatic. Need TypeScript? We'll use it. Existing Python codebase? We can work with that. But we believe in keeping things simple—no rocket ships, no over-engineering. Rails monoliths can take you further than you think.

Pricing

MVPs are fixed-price (typically €15k-25k). Optimization work is usually 2-4 weeks at €8k/week. Retainers start at €6k/month. No hourly billing, no surprises.
