Invest-NL
Invest-NL is the Dutch government's national impact-investment bank, based in Amsterdam. It backs sustainable and innovative companies that private investors find too risky or too slow, and in water it has funded three Dutch firms: Hydraloop, Paques Biomaterials and AQUABATTERY. As of January 2026 it is also a cornerstone investor in PureTerra's dedicated water-tech fund.

The take
Invest-NL is a development bank owned by the Dutch State, set up in 2019 to put public money exactly where private capital will not go: high-risk, slow-burning, mission-driven companies that struggle to raise from anyone else. The fund sums up its own deal with the world in one line, "impact is our goal, return is our means", and it means the second half literally, waiting longer for a return than a commercial investor ever would.
Water is a small but deliberate slice of that mandate. Invest-NL has directly backed three Dutch water companies, and it tends to lead those early rounds rather than follow: Hydraloop, which recycles greywater inside the home; Paques Biomaterials, which grows bio-based plastics out of wastewater; and AQUABATTERY, which stores energy in salt water. The pattern is consistent, hardware-heavy Dutch climate tech with long development timelines, the kind of bet patient public money is built to carry through the years before private funds get comfortable.
The clearest recent signal came in January 2026, when Invest-NL went one layer up the stack. Rather than back another single company, it committed ten million euros as a cornerstone investor in PureTerra Ventures' new water-tech fund, the only fund in the Netherlands dedicated entirely to water. Anchoring a specialist fund is how a development bank multiplies its reach, and it marks water shifting from a one-off theme into a named domain inside Invest-NL's 2026 strategy.
For a newcomer trying to place this name, the read is simple. Invest-NL is the patient, government-backed capital that de-risks Dutch water innovation early, so the private market can follow with confidence. It is rarely the loudest name in a funding round, but on the slow, infrastructural side of water it is one of the most reliable first cheques in the country.

Frequently asked
- What does Invest-NL invest in?
- Invest-NL backs sustainable and innovative Dutch companies across deep tech, the energy transition, agrifood and, increasingly, water. It targets businesses that private investors avoid because of high risk or long payback, usually taking minority stakes and often leading the early round. As of 2026 it has backed three water companies directly.
- Who runs Invest-NL?
- Invest-NL is led by CEO Rinke Zonneveld, who founded the regional investor InnovationQuarter before joining in 2022. Its Executive Board also includes Chief Business Officer Jellie Banga and Chief Financial & Risk Officer Jan Pieter Postma, both of whom previously sat on the board of Triodos Bank.
- Is Invest-NL a government fund?
- Yes. Invest-NL is a state-owned impact-investment bank, capitalised by the Dutch government to finance the country's energy and innovation transitions.

- What water companies has Invest-NL backed?
- Invest-NL has directly backed three Dutch water-tech firms: Hydraloop, which recycles household greywater; Paques Biomaterials, which makes bio-based materials from wastewater; and AQUABATTERY, a salt-water energy-storage startup. In January 2026 it also became a cornerstone investor in PureTerra Ventures' dedicated water fund.
- Is Invest-NL the same as Invest International?
- No. Invest-NL is the Netherlands' domestic development and impact-investment bank, funding companies inside the country. Invest International is a separate Dutch institution focused on helping businesses operate and invest abroad. The two were set up around the same time and share government roots, but they run independently.
