Why we backed AeroNero
Two billion people on this planet do not have reliable access to drinking water. AeroNero is one of a small handful of companies trying to solve that problem with technology that actually works at scale — and they are doing it from Chennai, for the markets where the problem is most acute.

Why does AeroNero fit the Callapina thesis?
AeroNero is Climate-for-the-Global-South: a hard-technology company solving water resilience for markets where affordability, infrastructure gaps, and climate stress all compound.
How does Callapina add value here?
Callapina focuses on three levers beyond capital: market access through US-India customer and partner introductions, fundraising support for the next institutional round, and strategy support around GTM, pricing, positioning, and operating cadence.
Why is this venture-scale?
Water reliability is a structural need across India, the Middle East, Africa, and disaster-response markets. The company’s challenge is making the technology economical and deployable at scale.
