In due dilligence on

Fund II's first investments 

Investment thesis

Fund II invests in early-stage technology companies who are already seeing commercial traction, nearing $1M in annual sales, and have IP that improves efficiencies and/or mitigates risks relating to water or wastewater in agriculture, aquaculture, buildings, climate, conservation, financial services, industry, power generation, and/or utilities.


Making an impact

Mazarine views water as a risk. Whether public or private sector, rich countries or poor countries, farmers, miners, builders, lenders, and the water at my kitchen tap, the management and use of water is a problem, a headache, ..... a risk. It's factual to say 'water is our most precious resource' or 'water is life', but when looking to make a social and/or environmental impact, Mazarine finds the most effective strategy is to back companies with innovations that help their customer reduce or eliminate water quality or quantity-related risks.


How does Fund II invest?

For seed-stage opportunities Fund II prefers to set the terms for convertible/safe notes, and we will likely make more than one investment over a period of 1-2 years as our confidence in the founder(s) grows. In Fund I, a majority of the companies received 2 or more checks from Mazarine. For priced rounds we tend to follow whomever the lead investor is.



Mazarine maintains an investor syndicate of early-stage investors including retired executives, angels, and other venture and impact funds.


In addition to their financial capital, companies in Mazarine Fund II benefit from the experience, expertise, and connections our syndicate brings to the table.  In Fund I, we led syndication for many of the portfolio company investment rounds, bringing in 14 other checkbooks who followed our due diligence and convictions on the company.   Syndication inquiries


We are technology investors, not 'water investors'

We don't invest in 'water', we invest in companies with IP rooted in Chemistry, Data Science, Diagnostics, Computer Engineering, Information & Communication Technology (ICT), Materials Science, Metagenomics, Microbiology, and Process Engineering. We are technology investors backing young companies with hardware, software, or business model innovations that address inefficiencies or risks relating to water and/or wastewater.

What problems are Fund II companies solving?

While their innovations address some aspect of water or wastewater, ultimately their customers face a myriad of inefficiencies and risks that might be better framed as Climate Adaptation risks, Environmental Protection risks, Business Continuity risks, and/or Public Health & Safety risks.


What industries are Fund II portfolio companies in?

In addition to utilities, the management and use of water is an operational, financial, or brand risk for many industries spanning agriculture, aquaculture, buildings, climate, conservation, financial services, industry, power generation, and transportation. Mazarine often finds itself in technology verticals where water/wastewater play a central role, including health-tech, climate-tech, fin-tech, prop-tech, reg-tech, insur-tech, and even transportation-tech. ​ 


How is the ESG framework utilized?

Measure impact by applying the ESG framework to score portfolio companies on how their innovation supports their customers’ ESG efforts.



Fund II is backing early-stage technology companies with innovations that support their customers' efforts to meet their ESG goals.
