• Private equity veteran joins as Partner and Head of Portfolio Operations
• Appointment strengthens Ambienta’s value creation capabilities across its private equity portfolio
• Hire brings significant expertise in digital transformation, including artificial intelligence and cybersecurity

Milan/London/Paris/Munich/Stockholm, 4 June 2026 - Ambienta SGR S.p.A. ("Ambienta"), one of Europe’s leading asset managers entirely focused on environmental sustainability, is pleased to announce the appointment of Jérôme Losson as Partner and Head of Portfolio Operations, Private Equity. 

Jérôme Losson joins the firm with more than 30 years of experience across consulting, direct management and private equity, with deep expertise in value creation, operational transformation and digital initiatives, including artificial intelligence enablement and cybersecurity. Most notably, he was instrumental in establishing KKR Capstone in Europe - one of the pioneering portfolio operations platforms in the private equity industry - as a member of its leadership team for close to a decade. He later served as a Partner and a Managing Partner at BC Partners having started his professional career outside academia at McKinsey.

Ambienta oversees a highly diversified global private equity platform, with investments comprising more than 130 manufacturing sites, employing over 10,000 people across four continents. The firm’s continued growth has increased the scale, diversity and complexity of its portfolio, which spans businesses with different cycles, priorities and supply chains, all operating in a global context. The global economy is also undergoing a structural shift, with decades of globalisation giving way to a more fragmented and less predictable environment marked by tariffs, geopolitical tensions, protectionism and less resilient supply chains. Combined with transformative trends such as artificial intelligence and the environmental transition, managing companies has become materially more complex.

Against this backdrop, Ambienta is materially strengthening its value creation capabilities, building on its already established and long-standing dedicated value creation function, with the addition of a seasoned leader to guide this next phase of development. This appointment represents a significant step-up in capabilities as the firm evolves towards a “Portfolio Management 2.0” approach: more integrated, data-driven and focused on scaling performance across an increasingly complex and growing platform. This includes strengthening operational excellence, enhancing supply chain resilience, accelerating digital transformation and AI adoption, and supporting portfolio companies in capturing growth opportunities linked to environmental sustainability.

At Ambienta, Jérôme will be responsible for portfolio operations across all companies in which the firm has invested, across asset classes, working closely with investment teams and management to enhance performance, accelerate growth initiatives and further embed operational best practices.

Nino Tronchetti Provera, Founder and Managing Partner of Ambienta, commented: “As Ambienta continues its growth trajectory, we remain committed to investing in top-tier talent to strengthen our platform. Accelerating the adoption of existing environmental solutions requires sophistication and best practices in managing companies; Jérôme and the portfolio management team have a key role in scaling the environmental champions engaged with our platform.”

Mauro Roversi, Founding Partner and Private Equity CIO, added: “Jérôme brings a unique combination of operational expertise and private equity experience, and we are delighted to welcome him to the firm. His leadership will be instrumental in further enhancing our ability to drive value across our portfolio.”

Jérôme Losson, Partner and Head of Portfolio Operations, added: “I am excited to join Ambienta at such a dynamic stage in its development. The firm’s clear focus on environmental sustainability as a driver of value creation strongly resonates with me. I look forward to working alongside the team to support portfolio companies in achieving their full potential.”
