Partner
Mathis is an operator first, with eleven years of C-level work across marketplaces, payments and B2B software. Most recently he ran Europe for Kestrel Pay, and before that he was co-CEO of Ledgerline, which he took through its sale to Harburn Growth.
Partner
Ilona has spent thirteen years building and scaling institutional investment platforms. During her decade at Thalheim SE she stood up the firm's investment management function as a third strategic pillar alongside its industrial holdings, and helped turn it into a cross-border platform backing late-stage technology companies. Her approach is built on long-horizon conviction, unglamorous sector depth, and a network she has spent a career earning rather than buying.
Vice President
Rasmus has executed deals since starting in leveraged finance in 2014. Before joining Yarrow he spent five years at Norrland Group, closing 14 investments across every stage, with exits spanning strategic M&A, sponsor roll-ups, two listings and a secondary block sale.
Analyst
Nadia came up through venture internships in Lisbon and Munich, covering early-stage grid software at a climate fund and European deep tech at a family office. She holds a double major in economics and statistics from Utrecht.
