We build products that work.

Web applications, marketplaces, and custom software. From first idea to launch. Senior EU team since 2003.

Trusted by founders, scaleups, and enterprise teams

Three ways projects usually start

Most clients come to us in one of these situations. The work is different each time, but we always aim to turn uncertainty into progress.

01 · Clarify Best for founders at day 0

Clarify the right MVP

Not sure what to build?

Many founders come to us with an unfinished idea, or several. We help set the direction: what to build first, the MVP scope, the platform, and a build plan.

  • Discovery workshops
  • MVP scoping and roadmap
  • Platform and architecture choice
  • Technical feasibility review
02 · Build Best for products ready to ship

Build and launch with confidence

Ready to build?

We build web apps, marketplaces, and internal tools, and we ship them as working products. Experienced developers write the code, and AI tools help them work faster.

  • Custom web applications
  • Marketplaces and SaaS platforms
  • Integrations and API development
  • Senior product engineering
03 · Rescue Best for stuck products

Stabilize, refactor, move forward

Stuck with what you have?

Maybe the previous team disappeared, every new feature takes longer than the last, or an AI-built prototype is hitting production limits. We help you sort it out fast.

  • Technical audit and diagnosis
  • Architecture refactoring
  • Performance and scaling fixes
  • AI prototype to production support

We have worked with Sharetribe since 2014. We've built the common marketplace features many times, so we know where the edge cases hide.

Built something with AI tools but hit a wall?

You built a prototype with AI tools, and now it almost works, but it still breaks on logins, payments and less common cases. We keep what works, replace what doesn't, and get you to production.

A few of the things we check first in an AI-built app:

  • Who can see what. Whether one user can reach another user's data.
  • Where the money goes. Payments and refunds, so no order is charged twice or lost.
  • Keys and secrets. Passwords and API keys that ended up in the code or the browser.
  • How the data is structured. Whether the database will hold up as you add features, or needs reshaping first.
  • What happens when something fails. Errors that vanish silently instead of being logged and fixed.
  • Code another developer can work on. AI tools often copy the same logic into many places, so one fix has to be made five times.
  • Real traffic. What breaks when a hundred people use it at once instead of one.

What makes us different

We know what it's like to build a product and take it to market. Experienced developers write your code, and you talk to them directly. Clients feel it in the daily work.

01

We think like product owners.

We've built our own products, pitched them, sold them, and felt the pressure of getting traction. We ask what will actually move the product forward. Then we figure out which features get you there.

02

AI where it helps your customers.

We look at your product and find where AI or automation saves your customers time or your team manual work, and build it in. Our developers use AI tools too, so they get more done in less time.

03

Senior team, real ownership.

You work with experienced developers who know your product, and you talk directly to the people doing the work.

04

Reliable by design.

We ship in small increments, keep communication direct, and tell you early when something needs to change. That makes the process calmer, and the delivery stronger.

05

We build our own products too.

Our advice comes from products we've built and shipped ourselves. We know what it feels like when roadmap, growth, and technical debt collide in the same week.

06

We stay with you after launch.

You get documentation, monitoring setup, and a warranty on what we ship. If the product needs ongoing help, we're here. If not, the product is yours to take forward.

About our care plans

Our first-sprint guarantee

If after the first sprint you don't feel like we're the right partner, we stop and don't invoice for that sprint.

Good partnerships start with trust. This is how we earn it.

A founder who still codes

IT House isn't run by account managers. The founder is hands-on in the code, the conversations, and the product decisions.

Gunars Grundstoks, Founder & CEO of IT House

I wrote my first program at 13, a rental management system for a local video rental shop. It worked, the customers were real, and I was hooked.

That feeling (building something that solves an actual problem for actual people) is why I started IT House in 2003.

Along the way, we built our own products, including a car rental marketplace, a wellbeing platform, and a calendar sync tool. We took them through Startupbootcamp and Ignite 100, traveled to different countries to meet customers face to face, and learned the hard parts of finding customers and making a product sustainable.

That experience changed how we build for clients. Code is one piece of it. We think as much about traction, clarity, and what your first version really needs.

Every project we take on, we treat like our own.

Products we've built

A live platform migration. A marketplace built from scratch. A legal product partnership that has lasted for years.

Betty Blocks product interface

Enterprise speed for a no-code platform

Betty Blocks needed millisecond response times to compete at enterprise level. We migrated their full codebase from Ruby on Rails to Elixir while the production system stayed live. The collaboration lasted several years.

  • Ruby on Rails → Elixir, the full codebase
  • Built for enterprise-grade concurrency and fault tolerance

They went above and beyond to meet tight deadlines on a complex migration. The quality of work exceeded our expectations, and they integrated with our team as if they were in-house.

They've been an integral part of our development team, helping to write clean code and automated tests. The daily collaboration was productive, and sometimes we even felt like they were reading our minds.
