Fred Van Efferink

Fred van Efferink is an experienced private-equity specialist who co-founded ICOS Capital in 2005, alongside managing partner Nityen Lal (a former AlpInvest and Deloitte consultant/investor) and partner Peter van Gelderen (a former Philips researcher and Deloitte consultant). His own background is rooted in private equity, which he brought to the founding team as the firm's financial/investment specialist. ICOS Capital Management B.V. is an independent Dutch investor that has positioned itself over two decades as a corporate-venturing and cleantech/climatetech fund.

Under van Efferink and his co-founders, ICOS built a model centered on partnering with large industrial corporates. In 2010 the firm announced the first closing of a cleantech fund in partnership with a consortium of listed Dutch industrials — Royal BAM Group, CSM, Imtech — and Delft University of Technology, to back innovative cleantech start-ups. Over its life the firm reports having invested more than €100 million across 40-plus European technology companies, with a team that collectively carries 75–100+ years of venture-capital experience and a track record of internationally syndicated deals, trade sales, and IPOs.

Today ICOS describes itself as a climatetech venture capital fund focused on food systems, chemicals and materials, sustainable industrial processes and digital technologies, and decarbonization. Note that as of mid-2026 Fred van Efferink is no longer listed on the firm's public team page (which currently shows Nityen Lal and Peter van Gelderen as general partners) — suggesting he may have stepped back from day-to-day duties — even though third-party databases (Crunchbase, RocketReach, Tracxn, PitchBook) continue to list him as a partner and his firm email ([hidden]) remains on record. This should be verified directly before treating him as an active deal contact.

• Invests through ICOS Capital, a Netherlands-based climatetech/cleantech VC, not as a solo angel — so check sizes and process reflect an institutional fund rather than personal angel tickets.
• Targets early-growth-stage companies that already have B2B market traction, rather than pre-revenue seed concepts.
• Core sectors: food systems; chemicals & materials; sustainable industrial processes and digital technologies; decarbonization / CO₂ reduction.
• Strong emphasis on a corporate-venturing model — co-investing and syndicating alongside large industrial corporates (e.g., BAM, CSM, Imtech historically) and research institutions like Delft University of Technology, giving portfolio companies industrial validation and route-to-market partners.
• Geared toward deep-tech / hard-science European startups where industrial scale-up and sustainability impact are central to the investment case.
