Ten years ago, WeAreBrain was founded with a clear intention: to build technology that genuinely matters. This week, that intention takes its most decisive step forward. WeAreBrain and Pulsr are merging to form a single company, operating under the WeAreBrain name, with greater depth, tighter focus, and the ambition to match.
A decade of building has pointed toward exactly this.
How we got here
The software development industry is undergoing a structural shift. Traditional agency models, built around delivery and execution, are under growing pressure as AI-native approaches change what’s technically possible and what clients actually need. AI has already reshaped how software is built. What remains to be seen is which organisations are positioned to lead in that new reality, and which are still catching up.
WeAreBrain and Pulsr have each been building toward this moment from different angles. WeAreBrain brings market presence, brand credibility, an established client base, and a decade of proven work in AI and product development. Pulsr brings a forward-looking vision and deep specialisation in AI-native architecture and data science. Together, the capability sharpens and the scope of what is possible expands considerably.
As Mario Grunitz, co-founder of WeAreBrain, put it: “Ten years ago we set out to build technology that genuinely matters. Every project, every client, every hire has moved us further toward the kind of company we always intended to become. This merger is the decisive step. We are not repositioning. We are sharpening something that has been in motion for a long time. WeAreBrain is now exactly what we built it to be, and we are only getting started.”
What the combined company stands for
The ambition is explicit: to build the definitive European AI-native technology powerhouse. That means moving beyond software delivery toward helping organisations reimagine how they build, own, and scale their technology from the ground up.
Three pillars define that direction.
- Sharper AI capability. The merger combines established delivery expertise with Pulsr’s technical depth in AI-native systems and strong data foundations, producing solutions designed for lasting structural value rather than AI bolted onto existing architecture. As Enrico Karsten, incoming co-CEO, described it: “AI-native architectures and solid data foundations are the baseline. What Pulsr has been building is precisely the technical foundation that makes this possible at scale. Bringing that into WeAreBrain means we can deliver AI-native systems that give organisations real control over their technology, reducing vendor dependency, building on open infrastructure, and creating something that lasts.”
- The venture edge. WeAreBrain has always carried a founder’s instinct into client work, shaped by years of building startups alongside client engagements. That instinct now comes with a growing pipeline of new ventures, adding real builder perspective to every engagement, and a deeper understanding of what it actually takes to make something succeed.
- European sovereignty. This is perhaps the most important pillar, and the one that most clearly reflects what both organisations have believed from the beginning. The combined company holds a firm commitment to European values: data privacy, open-source infrastructure, and genuine ownership built into the architecture of everything delivered. In a world where vendor lock-in is the default, we are building the alternative.
Sinas and One: the first tangible outputs
A defining marker of any merger is what it actually produces. The combined organisation will launch two products that signal this new direction concretely.
Sinas is an agentic orchestration and control layer that connects data, agents, and tools into secure, traceable workflows. It accelerates the delivery of value while reducing vendor lock-in, grounded in open source as a long-term commitment to the market rather than a tactical feature. Sinas is purpose-built tooling that reflects how the combined organisation thinks about solving problems: with the infrastructure to make AI actually work at scale, not just in demos.
One is a business operating system that unifies data and systems into a single, queryable interface. Where organisations currently manage sprawling stacks of disconnected tools, One creates a coherent layer through which data becomes genuinely usable.
Together, Sinas and One are the first chapter of what the combined organisation is building. From 2027 onwards, they will play an increasingly central role in how WeAreBrain delivers on its AI-native ambition.
A new leadership team
Joining Mario in leading WeAreBrain are Enrico Karsten, Kjeld Oostra, and Jeroen Thijs, a team built specifically for the direction the company is heading, combining delivery experience, data engineering expertise, and product vision.
Enrico joins as co-CEO and will work closely with Mario over the coming months to architect the company’s new organisational structure. Kjeld leads the AI and Data Science practice and, as the owner of Sinas, drives the technical innovation at the core of what WeAreBrain is building. Jeroen joins at strategic management level, contributing long-term direction to the organisation.
A new office, a growing footprint
Alongside the merger, WeAreBrain is expanding its physical presence with a new office in Valencia, joining existing locations in Amsterdam, Kyiv, and Lausanne. It is a practical signal of the scale and ambition behind this next chapter.
Ten years of building. A decade of learning. And now, the company WeAreBrain was always intended to become.
