The Water Innovation Funding Gap
Despite water technology’s critical importance for global sustainability, the sector faces persistent funding challenges that traditional venture capital models have struggled to address. This funding gap represents both a market failure and an opportunity that ZNL Growth Fund recognized early in its formation.
Water technology startups encounter unique obstacles in attracting investment capital. The sector’s long sales cycles, complex regulatory requirements, and capital-intensive infrastructure needs often clash with venture capital’s typical expectations for rapid scaling and exits. While software startups can achieve product-market fit within months, water technology validation frequently requires years of pilot testing and regulatory approvals.
Further complicating the funding landscape is water’s positioning as both a public good and a commodity. This dual nature creates market distortions where the true cost and value of water innovations are often understated. Public utilities, the primary customers for many water startups, typically operate under strict budget constraints and conservative adoption practices that extend sales cycles far beyond what most VCs will tolerate.
ZNL Growth Fund identified these structural challenges as an opportunity to pioneer a new investment approach. Traditional VC metrics like monthly recurring revenue and customer acquisition costs poorly capture the value creation in water technology development. Instead, ZNL recognized the need for patient capital aligned with the sector’s longer commercialization timelines and focused on both financial returns and measurable impact metrics.
The water sector’s funding gap is particularly acute in the growth stage, where companies need significant capital to scale proven technologies. While early-stage grant funding exists for initial R&D, and large corporations may eventually acquire mature companies, the critical middle stage often lacks appropriate financing options. This “valley of death” causes many promising water innovations to stall before reaching meaningful scale.
Recent climate events and growing water scarcity have highlighted the urgent need for water technology innovation, yet investment remains disproportionately low compared to other sustainability sectors. While climate tech broadly saw record venture investment in recent years, water-focused startups received only a fraction of this capital despite water’s fundamental role in climate resilience.

Companies must demonstrate quantifiable improvements in water efficiency, quality, or access. The fund’s proprietary Water Impact Rating System assigns scores across five dimensions: cubic meters of water saved/treated, energy efficiency gains, chemical reduction, accessibility improvements, and circular economy benefits.
Risk assessment follows a comprehensive protocol examining technology validation, market dynamics, regulatory environment, and execution capability. Special attention focuses on validating performance claims through independent technical due diligence and pilot results verification. The fund maintains strict requirements for operational metrics, including minimum revenue thresholds, gross margins above 40%, and customer concentration limits.
Performance tracking employs both traditional financial KPIs and impact metrics. Monthly portfolio reviews analyze revenue growth, gross margins, customer acquisition costs, and capital efficiency. The impact dashboard tracks water-specific metrics like millions of gallons treated/saved, treatment efficiency improvements, and beneficiary reach. This data feeds into quarterly LP reporting and annual impact assessments.
Beyond pure metrics, ZNL evaluates qualitative factors such as management team capabilities, corporate governance, and strategic partnerships. The fund actively supports portfolio companies in developing robust ESG policies and impact measurement frameworks. This comprehensive approach helps ensure accountability while driving both financial returns and measurable water impact.
Risk mitigation strategies include structured investment terms, board representation, and technical assistance support.
