Wilmington indoor climate tech start-up gets $3 million in seed funding

The Carbon Capsule diverts and purifies return air from commercial buildings, removing CO2, volatile organic compounds, particulates, and pathogens, so the air can be safely recirculated to occupants. By reducing the amount of outside air needed, installing the Carbon Capsule can provide significant energy savings from existing HVAC units.

Carbon Reform, Wilmington, closed on a a $3 million seed investment. The round was led by Azolla Ventures, a climate tech venture capital fund created by Prime Coalition.

Other participants in the round include Virya LLC, Revolution’s Rise of the Rest Seed FundPlug and Play VenturesGaingels, and Sussex County real estate developer  Preston Schell.

According to a release, commercial building HVAC systems require an enormous amount of energy, much of which is spent heating, cooling, or otherwise conditioning outside air. Any additional air purification done inside the building often adds additional energy usage, hurting both the building’s carbon footprint while adding to expenses. Carbon Reform’s Carbon Capsule system aims to change that equation.

“Azolla Ventures is proud to lead Carbon Reform’s seed round and support the company’s efforts to tackle greenhouse gas emissions from buildings,” said Amy Duffuor, general partner at Azolla Ventures and member of Carbon Reform’s board. “Carbon Reform’s modular carbon capture system is a game-changer. It retrofits into existing HVAC infrastructure to scrub CO2 from air, allowing carbon capture and sequestration in one device, alongside energy savings and indoor air quality improvement. We’re looking forward to supporting the Carbon Reform team during their next stage of growth.”

By combining traditional air purification techniques with novel permanent carbon capture technology, buildings with Carbon Reform’s products installed can get the best of both worlds: clean, healthy air low in CO2, volatile organic compounds, and pathogens, and energy savings from reduced outside air conditioning. The startup plans to use the seed funding to grow the team, expand facilities, and install the first full-scale pilot units in commercial buildings.


Jo Norris and Nick Martin, co-founders of Carbon Reform, said they are looking forward to realizing their technology and business model.

“As a women-led and LGBT-owned enterprise, we’re grateful and refreshed to have the support of investors who not only believe strongly in our climate and health mission but also embody the fundamental values we have as founders around diversity, equity, inclusion, and belonging, at every level of our organization,” said Jo Norris, co-founder, and CEO of Carbon Reform. “The security we feel in this support provides an invaluable framework for the groundbreaking work we are setting out to do.”

“We are excited to have the support of world-class investors that are helping us realize our mission of democratizing access to carbon capture technology,” said Nick Martin, co-founder and COO of Carbon Reform. “They each bring a unique skill set to our team, be it industry connections, culture-building strategy, or subject matter expertise.”
