Groundswell Ventures

Groundswell Ventures is a Denver, Colorado-based venture capital firm founded in 2018 by Jeremy Harkey, who serves as Founder and Managing Director. The firm invests at the intersection of climate tech and human wellness, backing tech-enabled solutions that reduce climate impact at its source, remediate environmental damage, and improve access to climate-related health solutions. Harkey and his team operate as experienced entrepreneurs and operators who have built companies themselves, a background that shapes the hands-on engagement Groundswell brings to its 23-company portfolio. Groundswell invests across Seed, Series A, and Series B stages with typical check sizes of $500K to $3 million. Portfolio companies fall across four themes: Environmental Remediation (clean-up of water, soil, and air), Clean Energy (scaling and accessibility), Sustainable Agriculture (resource efficiency and regeneration), and Human Resilience (healthy food systems, accessible health and wellness). Notable holdings include Public (fintech investing app, unicorn in 2021), Babylist (baby registry platform), Claros (advanced materials platform using nanotechnology to capture and destroy PFAS pollutants and recover precious metals such as lithium from waste streams), Circuit (last-mile delivery, $11 million Series A), Cambium Carbon (upcycled urban wood, Series A February 2025), and Camus Energy (grid intelligence platform, 2024). The firm published a 2024 Impact Report documenting measurable positive outcomes across the portfolio. Groundswell applies a positive screen for female founders and diverse teams, and operates a Leadership and Team Dynamics program designed to improve organizational effectiveness across portfolio companies. The firm's mandate combines genuine environmental urgency with the practical rigor of operator-investors who have run businesses themselves.
