Solid insight.Real change.
We build data platforms, analytics and AI solutions in Qlik and Microsoft – and become a partner who challenges you and creates value together with you.

At Tallmaker, we focus entirely on working with numbers. Your numbers. We make them connect and speak, and make them trusted and smarter.
That is how we make sure your data is structured, accessible and ready to deliver insight that creates business value – whether you are a small business with few systems or a large group.

Specialist expertise in data platforms, analytics and AI
Numbers that connect
We collect data from your systems – on-premises and in the cloud – store it and model it for analysis. Collection and business rules are automated, so you get a single source of truth.
- Data warehouse and modern lakehouse
- Automated integration from ERP, CRM and line-of-business systems
- Business rules in one place
Trusted numbers
Key figures that are traceable, up to date and calculated the same way every time. We build the processes that let the whole organisation trust the numbers.
- Data quality with checks and alerts
- Budgeting and forecasting processes
- Governance and shared definitions
Numbers that speak
Interactive apps and dashboards instead of static reports. You can drill down and see why the numbers are what they are – not just what they are.
- Self-service analytics for the whole organisation
- Drill-down to underlying causes
- Design that makes insight easy to understand
Smarter numbers
AI assistants, machine learning and data science that uncover patterns others miss – and let you ask your data questions in plain language.
- AI assistants with access to your data
- Forecasts and predictive models
- Questions and answers in natural language
We make Qlik even better
Qlik is fantastic, but now and then we miss a few ways to visualize data. That's why we have built our own extensions.

We think big together – and deliver in iterations
Our own take on agile, refined over more than 200 projects. It works just as well for a small company with few systems as for a large group.
- Sprint 0 · Kick-off
We learn your business
People, systems and processes. Challenges and pain points. Together we set the first priorities.
- 2–4 weeks
Prioritise
Every sprint starts with agreeing on what must, should and could be delivered.
- 2–4 weeks
Build and test
Implementation and testing, with short stand-ups and a shared Planner board for tasks and status.
- Every sprint
Approved and delivered
Every sprint ends with sign-off – and new data or apps in use. Then the next one begins.
We can come in as advisers before you invest, be a dedicated team that knows your data over time, or give you extra hands when things peak.
We don't aim to be the biggest, but we want to be at the forefront.
Tallmaker was founded in 2020 by people from small specialist teams that got diluted when they were acquired and grew large. We want to be an expert team of the right size, where everyone knows each other.
We are based next to Oslo Central Station – and are just as happy working at the client's site or remotely. We have a learning day every month, and go on a cabin trip and a trip abroad every year.
We deliver what we promise
“Tallmaker is, as the name says, made up of honest, no-nonsense people who can count, who tell you exactly what they can do and who deliver what they have promised, entirely without PowerPoint.”
“Tallmaker, as a good long-term partner, delivers strong expertise and real commitment. This has been important on our journey so far, and it will be just as important for us in the years ahead.”
“Tallmaker is first and foremost an incredibly good, inspiring and reliable sparring partner, whose experienced and dedicated people give us a great deal of confidence and stability day to day. They deliver consulting services in a pleasant setting and are a strategically important partner for us.”
Specialist expertise backed by a Nordic community
Aderian Group has established itself in Norway by acquiring Tallmaker and four other IT companies. We are still the same expert team – now with a larger professional community and more muscle behind us.
