New brand, veteran team

Stemming from the success of prior funds, we launched Mazarine Ventures in 2018 with a focus on hardware and software technologies that address water/wastewater challenges. Our Founding Partners bring the finance, science & engineering, technology, marketing strategy, and operational experience to drive success.  

"If you can't measure it,

you can't improve it"

People have been measuring and analyzing things for hundreds of years; however, the tools have significantly changed - especially in the last few years. We are intensely focused on innovations around data science, computer engineering, and information technology & communications as they relate to water/wastewater.

Our vision is straightforward

The broad and diversified global market for hardware and software technologies that address water/wastewater challenges is underserved by seed and venture investment. Mazarine is leveraging our 3 platforms to build a portfolio of the most promising hardware, software, and business model innovations to address water/wastewater challenges.

Human capital drives performance

Mazarine's leadership is Anders Hallsby, John Robinson, and Tami Fratis, who work in close collaboration with a bench of subject matter experts, venture partners, and advisors.
