Ruby on Rails consulting
Building something from scratch or need help with a brownfield Rails project? Evil Martians work in your repo, your Slack, your standups, and ship production code from day one.
Evil Martians method
We have been building Rails applications since 2006. MVPs, APIs, billing systems, admin dashboards, upgrades, migrations, major fixes… We come when needed and tackle your challenges, help you hire and train your own team, so after we leave you are in the best position to succeed.
We built the tools your team uses every day: lemans for agentic coding on Rails, TestProf for slow test suites, AnyCable for WebSockets, Inertia for intricate frontend, Action Policy for authorization, Lefthook for hooks.

Social proof
bolt.new
We built bolt.new’s Rails backend from the early architecture through $40M+ ARR, and we have been their engineering partner since 2021.
Whop
Whop runs $150M+ in yearly payments on a Rails monolith. We cut their CI time in half, twice, and moved 750GB from PostgreSQL to PlanetScale with zero downtime.
