WINT raises $36M Series D co-led by LIP Ventures and Inven Capital to expand its AI leak-detection platform globally after saving 1.15B gallons for 600 enterprise customers.
Key Takeaways
- WINT's platform prevented more than 1,300 water-damage incidents in 2025 alone, representing an estimated $100M in avoided losses across 1,500-plus facilities.
- The $36M round brings total disclosed funding past $70M, with returning lead Inven Capital signaling confidence in execution since the 2023 Series C.
- Wint's enterprise customer base grew more than 40% in 2025 to nearly 600 customers, with 30,000-plus systems now installed worldwide.
Lead
Israel-based WINT Water Intelligence closed a $36 million Series D on September 9, 2026, co-led by LIP Ventures and Inven Capital. The round follows a year in which the company's platform saved 1.15 billion gallons of water and prevented an estimated $100 million in property damage - figures that explain why two climate-focused investors decided the market story was worth pressing into.
What Does WINT Actually Do?
WINT deploys AI-enabled sensors and software at water entry points inside commercial and industrial buildings. The system monitors flow in real time, learns each facility's baseline consumption pattern, and flags anomalies consistent with a leak. In automated mode, it can shut off water supply at the source before a burst pipe reaches interior walls. The company calls the offering water intelligence to distinguish it from simpler flow meters that record usage without acting on it.
By late 2025, WINT had installed more than 30,000 systems across clients including HP, Suffolk Construction, and the Empire State Building. Those reference names span technology campuses, large-scale construction sites, and historic commercial properties - a deliberate spread that signals the platform is not a niche solution for one segment.
Why Is Inven Capital Back for a Second Round?
Inven Capital, the EUR 500 million European climate-tech fund backed by Czech energy group CEZ and the European Investment Bank, co-led WINT's $35 million Series C in 2023 alongside Insight Partners. Returning for the Series D is a substantive endorsement. The fund manages a portfolio aligned to the energy transition, and water efficiency sits inside that mandate. Re-participating communicates that the 2023 underwrite is tracking to plan rather than requiring a revised story to justify continued support.
LIP Ventures, a Latin America-based VC managing more than $220 million in assets under management, rounds out the co-lead. The geographic pairing is notable: Inven anchors European distribution while LIP opens a corridor into Latin American markets where water scarcity is acute and enterprise building infrastructure is increasingly receiving institutional capital.
What Does the Valuation Imply About the Last Round?
WINT did not disclose a post-money valuation. Comparison with the 2023 Series C is therefore imprecise. That said, the return of an existing lead investor at a higher absolute dollar amount, combined with 40%-plus growth in the enterprise customer base, is consistent with an up round. In December 2025, global property group Grosvenor made a separate strategic investment and committed to deploying WINT's platform across its real estate portfolio - a reference deployment that compresses enterprise sales cycles for any account a Grosvenor building touches.
Why Water Damage Now?
Water damage is the second most common source of commercial property loss after fire, and the insurance market has sharpened its underwriting accordingly. Carriers active in high-risk geographies have moved toward risk-based pricing that rewards mitigation - creating alignment between facility operators, landlords, and underwriters that did not historically exist. That structural shift is producing budget line items for water-tech that have to compete less with discretionary capex and more with mandatory risk management spending.
WINT's competitive field includes legacy building management systems vendors adding water monitoring modules, and specialized startups targeting municipal distribution networks rather than commercial buildings. WINT occupies the middle: enterprise facilities where the decision sits with risk officers and facilities managers, not engineers, and where speed of response matters more than granular utility data.
How Will the $36M Be Deployed?
The company stated it will accelerate product development and deepen market reach. Given Inven's European mandate and LIP's Latin American presence, geographic expansion appears central to the plan. WINT's current base sits predominantly in North America and Europe. Latin America, the Middle East, and parts of Asia-Pacific remain underpenetrated markets where building owners face water stress without viable mitigation tools.
Outlook
WINT enters this phase with a more defensible position than most water-tech companies can demonstrate at Series D: a specific damage-prevention record, institutional clients with public name recognition, and a returning lead investor. The next test is whether the unit economics hold in markets with weaker regulatory infrastructure and less-standardized building systems. The $36 million provides 18 to 24 months of runway for that experiment. Valuation discipline will matter more in the Series E conversation than it did in this one.
