Enterprise productivity across Europe is under pressure. As complexity increases through geopolitical shifts, labour constraints, and tighter operational interdependencies, many organisations observe that AI and optimization efforts improve local efficiency but fail to deliver structural, enterprise-level gains.
At Superlinear, we work on this gap through enterprise orchestration: enabling better system-level decision-making across people, processes, and machines in environments where siloed optimization no longer works.
In our earliest pilots with leading European enterprises, we observe that moving from local optimization to coordinated, enterprise-wide decisions can unlock significant latent capacity. Productivity gains in the range of 10–30% are achievable by reducing systemic friction rather than adding infrastructure.
The 500 largest European enterprises represent roughly €14 trillion in economic output. Enabling even a fraction of them to structurally improve productivity would have impact beyond individual companies.
This is a long-term effort that requires rigor, restraint, and people who care deeply about their craft, take responsibility for outcomes, and are comfortable working on complex, high-stakes systems. This role offers the opportunity to contribute meaningfully to the foundations of enterprise orchestration in Europe’s most critical organisations
