Custom web apps, built by senior engineers, and proven before you commit.
We design and build business-critical web applications in Ruby on Rails and React. Not brochure sites, not templates, real software that runs your business. And we let you see the core working before you commit to the whole build.

Software that does real work
Your operations, your data, your customers, your money. The kind of system where reliability is not a nice-to-have, where it has to keep running for years, and where a fragile build gets expensive fast. That is the only kind of work we take on.
Not the team for a brochure site
If you need a quick marketing page, we are honestly not your best option, and we will say so. We are the team for the app your business depends on, the one that would hurt if it went down or got something wrong.
Built for people who can't afford a wrong bet.
Founders with a real product
You need a business-critical product built and can't afford to get the first big spend wrong. We make the first step small and provable.
Teams outgrowing the workaround
The spreadsheet, the manual process, or the aging internal tool has hit its limit. You need real software in its place.
Anyone burned before
You've hired an agency that over-promised, ran late, and over-billed. Our whole model exists so that doesn't happen to you again.
The right tool for your product, not a house favourite.
Ruby on Rails, the backbone
- A robust, maintainable backend, API-only or full-stack with Hotwire.
- Test-driven with RSpec and code review, so changes stay safe as it grows.
- Deep version experience, Rails 4.2 through 8, including the upgrades between.
React & Inertia, when the UX earns it
- SPA-grade interfaces for dashboards, editors, and real-time work.
- Inertia keeps it on one Rails codebase, without a duplicated API layer.
- We'll tell you honestly when plain Hotwire is the simpler, better call.
And when your app needs to talk to other systems, a CRM, an ERP, a payment processor, that's a core strength, not an afterthought. See Integration & Automation →
Chances are, we've built your hard part before.
Since 2007 we've modelled the business logic that business-critical apps depend on, again and again. That means less to discover on your project, and less to go wrong.
Business logic we've already solved
Everything a business-critical app needs
How we work: proof before commitment
- Discovery call. A free, honest read on whether your project is a fit.
- Validation Sprint. Fixed scope, fixed price. We build the core for real and give you a fixed quote for the full build.
- Full Build. The complete app, with a written post-launch guarantee.
- Scale & Support. Ongoing work, or a dedicated team you can absorb in-house.
Why teams choose us
- Senior engineers, no handoffs. You talk to the people writing the code.
- Built to last. Test-driven, reviewed Rails meant to run for years.
- Low risk by design. A working core you see before the big commitment.
- Nearshore cost, EU timezone. Specialist work at a price that makes starting easy.
Do you build the frontend and backend together?
Yes. We own the Rails backend and the React or Hotwire frontend, so they are designed to fit instead of fighting across a team boundary. No finger-pointing, no integration surprises.
Can you take over a half-built project?
Often yes. We start with a short, fixed-price review of what exists, tell you honestly what is worth keeping, and give you a clear plan before any big commitment.
What does a business-critical web app cost?
It depends on scope, but you never start with a big blind commitment. You begin with a fixed-price Validation Sprint, and you get a fixed quote for the full build before you commit to it.
How do we start?
With a free discovery call, then a fixed-scope Validation Sprint that proves the core of your product before you commit to the full build.
Start by proving it.
