What ROM InWest does

ROM InWest B.V. is a Dutch regional development company (Regionale Ontwikkelingsmaatschappij) founded in 2021 and headquartered in Haarlem, North Holland. It is owned jointly by the Dutch national government (49.9%) and the Province of North Holland together with 21 municipalities (50.1%), operating under an explicit public mandate to address innovation financing market failures in the region. The company serves ambitious startups, scale-ups, and innovative SMEs in North Holland developing solutions with both financial return and societal impact.

Its core offering consists of three investment funds complemented by advisory services: the Transitiefonds (€100M target) for circular economy, sustainable energy, and food transitions; the MKB Fonds (€60M target) for digitalisation, AI, and Life Sciences & Health SMEs; and PDENH (Participatiefonds Duurzame Economie Noord-Holland), a closed-end legacy fund with over €70M deployed since 2014. Investment tickets range from €300,000 to €5,000,000, capped at 49.9% per round, with a mandatory minimum 25% private co-financing requirement. ROM InWest supplements capital with business development support via its proprietary GRIDT methodology and operates programmes such as the Smart Energy Hubs initiative (21 hubs coordinated) and, from January 2026, the PIM innovation programme.

The revenue model is that of a public fund manager: recurring management fees and transaction-related income on deployed capital, supplemented by carried interest or returns from successful exits in the portfolio. Returns are recycled through revolverende (revolving) fund structures rather than distributed to shareholders, and the company is part of a nationwide network of nine ROMs that share deal flow and cross-regional referrals. Key portfolio bets span MedTech (Healthplus.ai, HeartEye, Amplio Pharma, Confocal.nl), energy (Thorizon, Solarix, LIFEPOWR, Sympower, Dexter Energy), and circular economy (DOPS Recycling, Droppie, Root Sustainability, MUD Jeans, ThePhoneLab).
