What Cumulus does for your investment thesis
Cumulus is the monitoring infrastructure behind Blu Diamond Water Certificates. Every certificate is backed by continuous, instrument-verified measurement of water outcomes, independently audited and recorded in a transparent registry. That’s what turns water savings into a verifiable, tradeable asset. Cumulus is the verification layer that makes the asset class investable.
Water is the next frontier for impact infrastructure investment.
US water prices have risen more than 4% per year for the last five years, and scarcity trends suggest that pressure will accelerate. Global water infrastructure requires up to $7 trillion in investment by 2030 to meet demand. Less than 2% of that comes from private capital.
Blu Diamond Water Certificates bridge that gap. By converting verified water savings into structured, tradeable instruments backed by investment-grade insurance, Blu Diamond creates an asset class that combines the rigor of infrastructure finance with the scalability of capital markets.

Infrastructure finance rigor. Capital markets scalability.
Each Blu Diamond Water Certificate represents a verifiable unit of freshwater use avoided, reduced, or made available through conservation, reuse, or desalination projects. Investors purchase certificates pre-construction, providing upfront project capital. When the facility begins operations, certificates convert into tradeable units sold to corporate buyers retiring them against their water footprint.
The Cumulus monitoring platform provides the continuous, deterministic measurement that makes every certificate verifiable, auditable, and tradeable.

From certified project to realized return.
2. Activate
Investors purchase ex-ante certificates, providing upfront capital for construction.
3. Realize
On commissioning, certificates convert to ex-post units sold to corporate buyers, generating returns.
