Software for companies that have outgrown spreadsheets and off-the-shelf tools.
We build the internal systems, integrations and platform rebuilds that mid-sized businesses and SaaS companies run on. Scoped properly, delivered by a small senior team, and kept running after launch.
Three kinds of work, one way of working
Every project starts with a short, fixed-price discovery sprint so you know the scope and the cost before committing to a build.
Web apps and internal tools
The system your team actually works in: casting management, scheduling, order handling, dashboards. Built for your workflow, not a generic one.
How we build themIntegrations and automation
Connecting the tools you already pay for so data stops being re-typed. ERPs, CRMs, payment and identity providers, partner APIs.
What we connectPlatform modernisation
Moving a legacy platform onto a modern stack without stopping the business. Parallel running, batched migration, old system retired only when nothing depends on it.
How the migration worksTwo systems our clients run their business on
BATS CRM: replacing a live CRM platform with no downtime for customers
From a consulting assessment to a redesigned platform, every tenant migrated in batches, the old system decommissioned, and ongoing technical leadership of the company.

The system the casting crew uses to manage people, offer and track roles across every project, and produce exports for costume teams and billing. In daily use since 2023.
Read the case studyScope first, then build, then keep it running
Discovery sprint
One to two weeks. Workshops with the people who will use the system, a clickable prototype, an architecture outline and a fixed-price estimate for the build.
Fixed-scope build
Six to twelve weeks for a typical system, at a fixed price agreed after discovery. Weekly demos of working software, a small senior team, and code you own from the first commit.
Support retainer
After launch, a monthly engineering bucket sized to the system, from a few hours for a small tool to a full-time team for a platform, with a response-time commitment.

Run by an engineer who has done the whole cycle
Mimir Solutions is led by Davor Mićić, Director of Technology at BATS CRM and a .NET engineer since 2019. He scopes every project, owns the architecture and builds a small team around it, so the person who promised the result is the one responsible for delivering it.
