The Opportunity

Problem

Climatetech SaaS founders struggle to build remote teams due to a shortage of domain experts in sustainability metrics capable of asynchronous work across timezones.

Solution

SustainSync streamlines remote hiring with async coding challenges, metrics simulations, and peer reviews tailored to sustainability expertise. Founders assess candidates across timezones via recorded responses and AI scoring. Build confident remote teams faster with zero-sync interviews.
