Callapina saw water-from-air as a Global South infrastructure problem, not a niche climate product. They helped us think about international credibility, partnerships, and the right market sequencing.

Common diligence questions

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.
