Monterro opens London office to strengthen support for portfolio company expansion across Europe

The London office will strengthen Monterro’s ability to support portfolio companies with international expansion, both organically and through add-on acquisitions, while deepening its position in the European software ecosystem.

Monterro, the largest Nordic B2B software investor, is opening its first UK office in London, strengthening its local presence in one of Europe’s key financial and technology hubs. The office will support portfolio companies as they expand across Northern Europe, and bring Monterro closer to software companies, advisers, experts and potential add-on opportunities.

The expansion comes as the UK technology sector continues to grow rapidly, with a combined market valuation of $1.6 trillion in 2026 and the UK being the fastest AI adopter in the G7.

 
Situated in Soho, the new London office will have a broader Northern European remit, with the UK as an important part of the regional platform. It will enable Monterro to work even closer with portfolio companies as they expand into new markets, build their organisations and pursue strategic acquisitions across the region. 

“International expansion is a key growth driver for our portfolio companies, both organically and through acquisitions,” said Gustav Lagercrantz, CEO of Monterro. “London is one of Europe’s most important financial and technology hubs and having people on the ground in the region gives us an excellent base from which to support our portfolio companies more closely, while strengthening our Northern European network. Our portfolio companies have ambitious growth agendas, and our role is to help them succeed.”

"The UK has always been a very attractive market for us. It is home to a deep pool of well-run, often founder-led B2B software companies, and the business culture here - entrepreneurial, ambitious but financially sound - fits well with the way we work alongside management teams. We have already completed several acquisitions in the UK, we have a number of dialogues ongoing, and we intend to continue on that path," add Lagercrantz.

Monterro has grown rapidly in recent years, more than doubling AUM to a current €3.1 billion in assets under management, following the €1.725bn close of its latest M5 and G2 funds in September 2025. The firm combines capital with hands-on operational support, helping B2B software companies accelerate growth, expand internationally and develop into market leaders in the AI Era.

Add-on acquisitions have long been an important part of Monterro’s approach to value creation. Since its inception, Monterro has completed more than 100 transactions, including approximately 60 add-on acquisitions. The majority have been cross-border, helping portfolio companies enter new markets, broaden their product offerings and strengthen their competitive positions.

As part of its hands-on model, Monterro also supports portfolio companies across go-to-market, product development, organisation and AI transformation, including through its newly launched sovereign AI infrastructure platform Enclave.

The London office complements Monterro’s existing offices in Stockholm, Oslo, Copenhagen, Helsinki and its software development centre in Hanoi, and marks another step in the firm’s continued expansion across the European software ecosystem.
