About
Reaktor Group
Who we are
We are a global technology company specializing in digital innovation, software development, and strategic design. Our story began in Finland in 2000, and today, we are a team of over 700 designers, developers, and strategists worldwide. We have offices in five countries around Europe, North America, and Asia, and are headquartered at the heart of Helsinki.
Our work has three dimensions. We partner with organizations across aero, defence and security, healthcare, industrial, gaming, retail, and the public sector to solve mission-critical technology challenges. We also develop our own software, turning deep domain expertise into products that solve hard problems at the sharp end of industries. And through our ecosystem, we invest in and co-found over 40 independent technology companies, backing founders who are serious about what they're building.

Custom solutions
We work with some of the world's most demanding organizations, from global enterprises to government agencies, on the technology problems that can't afford to go wrong. Our teams embed directly with clients, bringing engineering, design, and strategic thinking to bear on challenges that are too critical or too consequential to outsource to a generalist.
We operate across aero, defence and security, healthcare, industrial, gaming, retail, and the public sector. With a 97% net revenue retention rate and a DORA score 16% above the industry average, the quality of the work speaks for itself.

Productized solutions
We turn the deep domain knowledge we've built over 25 years into software products that solve specific, hard problems in high-stakes industries. Our product business is growing, with software already in the defence and security market and more coming across other industries. Every product is shaped by real industry knowledge and built in close collaboration with the people who use it.

Reaktor Ecosystem
Our ecosystem is a handpicked alliance of 40+ independent technology companies spanning the full breadth of the digital spectrum. Accelerated by Reaktor, they operate as one tightly connected network. We invest in and co-found companies alongside founders who are serious about what they're building, and we bring more than capital: engineering credibility, domain expertise, and a network built over two decades.

How we work
We've been building software long enough to know where the industry is heading. Four principles shape how we stay ahead of it.
Industry specialization
As software complexity grows, so does the value of knowing an industry from the inside. We go deep in the sectors we serve, so our clients get expertise, not generalists who've read the brief.
AI and data capabilities
We integrate AI and data-driven technologies across every stage of how we work and what we build. For our clients, that means faster decisions, sharper products, and delivery that keeps pace with what's possible.
Productized offering
We build modular, reusable software that travels. What we develop for one client or market can be adapted and scaled across others, compounding the value of every build.
Lifecycle partnerships
We don't hand off and disappear. We offer support across the full arc of a product, from identifying the right problem to design, development, and long-term maintenance.
