Portfolio Spotlight: Sunairio

Congratulations to our portfolio company, Sunairio, for successfully closing their latest $6.4M funding round led by Buoyant Ventures alongside Constellation Technology Ventures and MassMutual Ventures Climate Tech Fund.

We co-led Sunairio's first round alongside Thin Line Capital, Intelis Capital and MVP Capital back in 2022. When we invest as early as pre-seed, we look for strong founder expertise and signs of market demand validation. Sunairio’s founder and CEO, Rob Cirincione demonstrated both in spades. A former energy trader with deep energy industry domain expertise, he brings a unique vision to an increasingly urgent problem.

Sunairio is the first software company to leverage high-resolution climate data to simulate energy asset risk and grid variability. Unlike traditional, computationally intense, physics-based climate models that only predict average regional weather, Sunairio incorporates advanced statistics and generative AI to produce site-specific, asset-level climate simulations that integrate with existing energy modeling tools to support commercial decision making.


As more companies transition towards renewable energy – and as climate change makes forecasting more challenging – Sunario becomes more and more critical to reducing risk and uncertainty, improving planning, and driving impact.

We’re excited to support Sunairio’s continued growth.
