Inexcel helps companies turn ideas into working prototypes in weeks, and prototypes into products. We bring the product mindset that decides what is worth building, and the AI-assisted development that builds it fast: coding agents in your team, AI agents in your workflows, and agents built into the product itself. And when an idea needs to be held, we 3D-print it.
Some of it we do for our own products, most of it together with you. The method is the same: start from what customers need, put something real in their hands early, and let AI do the heavy lifting.
See your idea work before you bet on it. We build working prototypes, real code on real data rather than slides, so you can put them in front of users and investors within weeks and decide on evidence.
Most products fail on what they build, not on how well they build it. We help teams start from the customer's problem, shape the features that matter and measure what happens, the way we run our own products.
Coding agents change how software gets built, and they are only as good as the context they get. We help your developers work with them well: specifications agents can follow, skills and guardrails for your codebase, and reviews that keep quality up as the pace goes up.
Much of the work in an organisation is the same steps, again and again. We find it and hand it to AI agents, and we build agents into your product so your users get the same leverage.
Some ideas are easier to judge in your hand than on a screen. We have our own 3D printer and print parts, enclosures and models on demand, in a range of materials, and connect them to software when the prototype needs to do something.
Parts, enclosures, fixtures and models, printed in-house in the material that suits them, and reprinted quickly when the design changes.
Sensors, microcontrollers and displays for a prototype that has to sense, move or show something.
An app or a dashboard that talks to the device, so the prototype works as a whole.
We start with the problem and the people who have it, not the solution. A short workshop is often enough to know what to build first.
A clickable flow, a working app built in days with AI, or a 3D print on the table. Something to show users and investors while it is still cheap to change.
We turn what works into a product built to last: specified, tested and secure, with coding agents doing the heavy lifting and people owning the decisions.
We ship, measure what happens and improve. Or hand it over to your team, documented, together with the agent setup that built it.
Building and running our own products is how we learn what it takes, and it is where our advice comes from. Here is what we are building now, and what came before.
Every adventure, told by everyone who was there.
Trips, weddings, birthdays and reunions: the best photos and stories are spread across everyone's phones. Mystory brings them together in one shared story. Photos, videos, voice notes, routes and words from the whole group, on one map and day by day. Play it as a slideshow, share it with the people at home, or turn it into a photo book.
Everyone on the trip adds their own photos, notes and recordings to the same story.
At a wedding or a party, guests scan a card on the table and add their photos.
Each day gets its map, places and weather, without typing a word.
Talk instead of typing, and let AI tidy the text or sum up the day.
Every story is laid out as a book you can read on screen or print.
Nothing is shared until you choose to share it.
Product development for the agentic AI era.
When coding agents write much of the code, the hard part is knowing what to build, and keeping people and agents pointed the same way. ProductMind captures what customers need, turns it into living feature specifications, and hands the work to coding agents with the right context. Every shipped change traces back to the customer who asked for it.
Unit testing for mainframe developers.
Banks, insurers and governments still run on COBOL and PL/I programs on the mainframe, and changing them safely is hard. XaTester gave mainframe developers what other developers take for granted: automated unit and functional tests for their programs, built and run from a modern Eclipse IDE, without writing test code.
XaTester was built together with the Danish IBM business partner Xact Consulting. In 2018 Compuware acquired it and merged it into Topaz for Total Test. It lives on today in BMC AMI DevX Total Test.

Founder of Inexcel AB · Co-founder of ProductMind
“AI has made building cheap. Knowing what is worth building is now the hard part, and the part I enjoy most.”
Steen has spent his career building software products, many of them tools for other developers. He built XaTester, which brought automated unit testing to mainframe developers, together with the Danish IBM business partner Xact Consulting. IBM resold it, and in 2018 Compuware acquired it.
He joined Compuware as senior product manager for the combined product, Topaz for Total Test, which lives on at BMC. He has taken a product from idea to acquisition, and knows the work it takes at every step.
He co-founded ProductMind, a platform where customer feedback, specifications and coding agents share one context. Building it means living what Inexcel advises: product thinking first, and AI agents doing more of the building every month.
Today he runs Inexcel from the Malmö area, builds Mystory, and helps companies build their products faster with AI.
