HULO, a Dutch water-technology startup that uses artificial intelligence to find and prioritise leaks in drinking-water networks, has closed a €2.3 million seed round to accelerate product development and market expansion. The round was led by VP Capital, co-led by LUMO Labs, and included Vanagon, Rabobank, the Frisian Development Fund (FOM) and the NEW-TTT programme.
Why the problem matters: huge volumes of water are lost before customers get it
Water utilities worldwide struggle with “non-revenue water”, treated water that is lost through leaks, bursts, metering errors or theft. Industry assessments estimate that roughly 30% of water produced is lost on average in distribution systems, with some studies quantifying global losses as about 346 million cubic metres per day (around 126 billion cubic metres per year). That level of loss has large environmental and financial costs for utilities and communities.
What HULO’s technology does
Founded in 2021 by Robbert Lodewijks and Frank van der Hulst, HULO’s cloud-native platform analyses existing pressure and flow data from utilities to detect, localise and prioritise leaks in near real time. The company combines machine-learning models with physics-based hydraulic analysis so utilities can use their current telemetry, without deploying large numbers of new sensors or creating district-metered areas, to surface where to send crews first. HULO says what previously took weeks to pinpoint can now take minutes.
Funding, track record and prior backing
The €2.3m seed injection follows an earlier €800k pre-seed round announced in late 2023, led by LUMO Labs and supported by Netherlands enabling water-technology programmes. The new capital will be used to expand HULO’s footprint beyond Europe, with explicit plans to accelerate entry into Latin America, and to beef up AI, network analytics, cybersecurity and customer-success capabilities.

Investor rationale and impact claims
Investors point to the twin pressures of climate change and ageing infrastructure. Erica van Eeghen of VP Capital stressed the urgency of reducing water loss, while LUMO Labs highlighted HULO’s measurable potential impact, citing projections the company could help save the equivalent of millions of Olympic swimming pools by 2030 if adopted widely. Those impact estimates come from HULO’s measured simulations and investor commentary; real-world savings will depend on deployment scale and how quickly utilities act on insights.
Operational advantages and constraints
HULO’s selling points are clear: it leverages existing operational data, integrates as a SaaS product, and promises rapid localisation and prioritisation, which should reduce leak detection time and help utilities optimise repair schedules. However, success depends on data frequency and quality (some utilities sample pressure/flow only infrequently), integration with field operations, and local regulatory or procurement hurdles. Analysts note that while AI and analytics can significantly cut detection time, follow-through, repairs, financing and maintenance, determines actual water-savings.
Market opportunity and competition
The water-loss problem is global and persistent, creating demand across both developed and developing markets. HULO will compete with other meter-analytics and sensor-based vendors, but its differentiation is the claim of deploying without heavy hardware retrofits. Wider adoption will require proven pilot results and clear return-on-investment cases for utilities. Sector data also shows watertech funding and interest have been rising in recent years, creating a supportive investment climate for specialised solutions.
Will AI Finally Plug the Leaks?
HULO’s €2.3m round provides the company with a runway to scale commercially and to extend its AI and analytics for different utility sectors. The tech is one that visibly solves a problem – very high non-revenue water – but the main test will be that of substantial leakage reductions and how fast utilities turn insights into repair work. As a consequence of investors and policymakers demanding more water efficiency, startups such as HULO will be under a microscope for their proven, replicable outcomes.
