Mathias Thomsen has spent more than twenty years in the rooms where owners make their most important decisions. His career bridges the worlds of principal investing, complex M&A, global operations, advanced technology and impact— giving him a rare perspective on how value is created, protected and grown over long horizons.

He started unusually early. At 22, still in business school, Mathias initiated what became the largest M&A deal of its time for the largest family owned mega conglomerate in Denmark: a $3bn acquisition for Maersk that reshaped the company’s global position. It was his introduction to high-stakes decision-making, board-level judgment, and the responsibility of advising people who actually own and run companies.

He was then engaged by the oldest private equity firm in Europe, 3i, working on a $1.5bn buyout in marine infrastructure — a deal that became one of the firm’s most rewarding investments. For nearly a decade, he continued as a discreet advisor to the owners through restructurings, recapitalisations and spin-offs. This long arc of work taught him how families, founders and long-term investors think — and what they expect from someone they trust.

Mathias earned his MBA with Distinction at London Business School as a Dean’s List Scholar and advanced finance TA, with a semester on quantitative investment at Chicago Booth. This sharpened the analytical discipline behind his judgment, but his instincts were shaped long before — working directly with principals whose decisions carried generational consequences.

After years advising on investments, Mathias made a deliberate shift: from advising capital to building. He joined Uber at the height of its global expansion. As the founding leader in Denmark, he grew the business from zero to $40M ARR in nine months, navigating regulation, public controversy and the operational chaos of a hyper scaler, before it became the $200bn mobility platform it is today. It taught him how to lead through complexity, pressure and real consequence.

This led to Airbus. Working directly with the CTO and CEO, Mathias was entrusted with a $100M+ annual mandate to build the company’s eVTOL and urban air mobility business — full-scale aircraft prototypes in Silicon Valley and Germany, operations in São Paulo, and technology accelerators in Shenzhen. It was a rare vantage point into how global industrial champions build the future.

After relocating to Los Angeles — now the capital of advanced mobility and clean tech — he founded Hive, designing a model to use electricity cost arbitrage to make EV access free or affordable for high-mileage drivers. He later led Akute Networks, a nonprofit organisation, advancing drones, eVTOLs and autonomous ambulances to fundamentally improve emergency medical response and save lives.

Across every chapter, Mathias has worked closest to where the owner feels the weight: moments of uncertainty, moments of opportunity, moments when the next decision truly matters.

Today, as co-founder of Nima Partners, he works with family offices and business owners as a trusted advisor — bringing the uncommon combination of principal-investing experience, global M&A judgment, deep operational leadership and advanced-technology understanding. Clients turn to him when they need clarity, when stakes are high, and when they require someone who has been through complex decisions from every side of the table.

Originally from Copenhagen and shaped by years in London, Paris, Chicago, New York and now Los Angeles, Mathias brings a global perspective grounded in Nordic trust, discretion and calm.
