ESG Squad

We have noticed a frustrating paradox: the people hired to drive corporate sustainability spend almost all their time doing compliance paperwork. Our squad exists to fix this. We are building a frictionless reporting engine, linked directly to our core GHG capabilities, that takes the heavy lifting out of ESG data collection.

We want to flip the script. By researching innovative ways to integrate with existing company processes and using AI to its fullest potential, we are stripping away the tedious reporting work. When we do our jobs right, ESG teams get their time back, time they can redirect into creating concrete, high-impact climate action plans. In this squad, the code you write directly translates into fewer hours spent on compliance, and more hours spent decarbonizing the economy.
