WEAREFABBRIK · CUSTOM SOFTWARE DEVELOPMENT

Custom software that ships, and that you fully own. Built for European founders and SME owners.

You get the web platforms, SaaS, and AI tools your business runs on, built by WeAreFabbrik, a team that ships its own products too. Callen AI, our AI receptionist, answers and books real clinic calls live today. So you hire people who have already taken a product from idea to paying customers.

THE FIRST STEP
Start with a plan
A fixed quote and a build plan, yours to keep, whoever builds it.
THE PROBLEM

Custom software is easy to start and hard to finish.

Projects stall halfway. Bills drift past the estimate. The system meant to run your business turns into code your team is afraid to touch. You are left further from launch than when you started, with less budget to get there.

The difference is rarely the technology. It is having senior people who agree the scope up front, build in milestones you sign off one at a time, and stay on the job until it is live. That is how we work, and how we shipped our own product before we sold the approach to anyone.

Fixed price

Agreed before we start.

You own it

Full source code and IP.

One team

The same engineers, start to finish.

WHAT WE BUILD

Production software, built end to end.

One senior team owns the whole build, from architecture to launch, so the work never falls through the gaps between design, engineering, and ship.

  1. 01

    Web Platforms & SaaS

    Multi-tenant web apps and SaaS, accounts, billing, dashboards, and admin, architected to grow with your user base rather than get rebuilt at the first scale-up.

  2. 02

    AI-Enabled Applications

    Software with AI in the core, voice agents, chat, and document processing, from the team that built and runs Callen AI in production.

  3. 03

    MVPs for Funded Startups

    A working product your users and investors can use, shipped in 8–12 weeks, with code your own team can pick up and extend.

  4. 04

    Internal Tools & Automation

    Portals and workflow tools that replace the spreadsheets and manual re-keying your team loses hours to every week.

  5. 05

    APIs & Integrations

    APIs and integrations that connect your CRM, billing, phone system, and third-party tools into one system that shares data cleanly.

  6. 06

    Legacy & Prototype Rebuilds

    We rebuild fragile legacy systems and early-stage prototypes, including Lovable and Replit builds, on foundations you can ship and maintain.

HOW WE WORK

Three phases. Milestones you sign off. A price you agreed.

  1. Phase 1

    Technical Blueprint

    We map the plan, settle the scope, and give you a fixed price for the build. The plan is yours to keep, build it with us or take it to another team.

  2. Phase 2

    Build

    Senior engineers build in fixed-price milestones you approve one by one. You see working software at every milestone, all the way to launch.

  3. Phase 3

    Ship & Scale

    We put it live and stay on for as long as you need, maintenance, new features, and extra engineering capacity on tap.

WHO THIS IS FOR

For teams who need software that reaches launch.

Funded Startups

You raised to build a product, not to manage an agency. You get a launch-ready product and code your own team can own later.

DACH & EU SMEs

You are replacing manual work or ageing systems. Our Estonian company (WeAreFabbrik OÜ) makes EU contracts and invoicing simple across the DACH region and the wider EU.

Regulated & Fintech

You work under financial or regulatory rules where mistakes are expensive. We have shipped compliance software that runs inside banks and financial platforms accountants rely on.

Founders Adding AI

You have a product and want AI built into it properly, voice, agents, or automation, by a team that runs its own AI product.

INVESTMENT

Fixed price, agreed before we start, not an open-ended hourly bill.

From €3,000
  • The architecture and technical scope
  • A fixed price for the full build
  • A plan yours to keep or take elsewhere
  • Credited to your build if you proceed

Best for: teams who want a firm plan and price before they commit

Recommended
Build
€30k–€180k
  • Fixed-price milestones you sign off
  • A senior team, first call to launch
  • Working software early and often
  • Full source-code and IP ownership
  • Built in your stack

Best for: companies building a real product or platform they need to own

Ship & Scale

  • Maintenance and monitoring
  • New features on reserved capacity
  • Dedicated team extension
  • The same senior engineers, retained

Best for: teams with live software that needs a senior team behind it

Every project is fixed-scope and quoted before we start. You own the full source code and IP and can move it to any team, no lock-in. As an Estonian company, our EU contracting and invoicing are simple.

WHY US

We ship our own products, not only yours.

You get a small team of senior engineers who build and run production software, and who took their own product all the way to paying customers. You are hiring people who have already done the thing you need done.

  • Callen AI, our own AI voice receptionist answers inbound calls and books them into the calendar, live in 30 minutes and self-serve. We built the product, the billing, and the go-to-market.
  • IMTF, we built a document management and archiving module for this Swiss firm, whose anti-financial-crime software runs inside banks worldwide.
  • Finalysis, we built the SaaS platform that turns raw financial data into reports, forecasts, and company valuations for accountants and their SME clients.
  • 50+ projects delivered across 8 countries since 2018.
  • Led by Konstantinos Tsolakidis, a fractional CTO with 20+ years of engineering leadership.
  • A small senior team writes every line, the same people from your first call to launch.
FREQUENT QUESTIONS

The quick answers.

How much does custom software development cost?

It starts with a Technical Blueprint from €3,000, which gives you the architecture and a fixed price for the build, and is credited to the build if you go ahead. Builds themselves run €30,000–€180,000 depending on scope, quoted in fixed-price milestones you approve as you go.

Do we own the code and IP?

Yes. You own the full source code and intellectual property, documented and handed over. We build in your stack and your accounts, so you can move the work to any team whenever you want.

How long does a custom software project take?

A production-grade MVP is typically 8–12 weeks. Larger platforms run across fixed milestones you sign off as we go, so you see working software throughout. The Technical Blueprint gives you a firm timeline before you commit.

Can you take over an existing or early-stage codebase?

Yes. We regularly rebuild fragile legacy systems and early prototypes, including Lovable and Replit builds. We review what exists, tell you plainly what to keep and what to rebuild, and put it on foundations you can maintain.

What makes you different from a bigger agency?

The same small senior team builds your software from the first call to launch, and we ship our own products alongside client work. You get people who have taken software to production for themselves, working directly on yours.

Do you work with DACH and EU companies?

Yes, it is a primary market. WeAreFabbrik is Estonian-registered (OÜ), so EU contracting and invoicing are simple. We deliver remotely across the DACH region and the wider EU from our team in Athens and Tallinn.
