Nobody remembers the air they were breathing when something important happened. Jennifer Nuckles noticed that. Most people who spend their careers selling cleaning products, gaming apps, telehealth platforms, and fintech services would have trouble explaining what they all have in common. Nuckles doesn't have that problem: they all touch people's lives at scale, and she has spent 25 years finding ways to make those lives measurably better.
She became CEO of R-Zero in October 2022, stepping from the boardroom into the corner office at a company building UV-C light technology, occupancy sensors, and AI-powered analytics to make indoor spaces safe and efficient. Her logic was simple: humans spend 90% of their time indoors. The technology designed to manage those spaces - HVAC systems, basic air filters, chemical disinfectants - was built for a different era. R-Zero is the replacement.
"We spend 90% of our time indoors, but there has been a lack of innovation around improving indoor air health."
- Jennifer Nuckles, announcing R-Zero's $105M Series C, 2023
The career path reads like someone designed it deliberately. Nearly a decade at The Clorox Company, running household brands and launching the first new Clorox brand in decades with a sustainability angle. Then the pivot to digital: CMO at Zynga, the social gaming giant, navigating leadership turbulence while keeping the marketing engine running. A move into digital health as CMO at Doctor on Demand, followed by a high-stakes run at SoFi as EVP and Group Business Leader - responsible for a $1.5B P&L and 4,500 people as a named Section 16 officer.
What makes that path coherent isn't the industries. It's the operating philosophy. Nuckles runs on a principle she describes as "hire the athlete, train the skills" - she looks for adaptability over pre-existing expertise, which is convenient, given that she has spent her own career proving the approach on herself. A Harvard MBA and a UC Berkeley BA give her the credentials; five successful technology exits give her the track record.
"I'm excited to help impact the company's next phase of growth as R-Zero becomes the obvious choice for enterprises looking for validated, efficacious, and efficient solutions to help protect their most valuable asset of all - their people."

At R-Zero, she closed a $105M Series C in February 2023 - an unusually large round for a hardware-plus-software infrastructure play. The investor list tells the story: BMO Financial Group, Qualcomm Ventures, Upfront Ventures, and existing backers DBL Partners, World Innovation Lab, Mayo Clinic, Bedrock Capital, SOSV, and John Doerr. Mayo Clinic's presence is not decorative. R-Zero's UV-C technology neutralizes 99.99% of airborne and surface microorganisms, and healthcare is one of its primary markets. The technology also produces 90% fewer greenhouse gas emissions than traditional HVAC and chemical approaches, which is why the climate investors are there too.
The platform she is building is not just disinfection. R-Zero combines UV-C devices, IoT occupancy sensors, HVAC filtration upgrades, and an AI analytics layer into what she calls a smart building platform - giving building operators a real-time view of indoor air quality, space utilization, energy consumption, and maintenance. The pitch to a building owner: one platform to meet sustainability standards, reduce operating costs, and keep occupants healthy. The pitch to a CFO: a return on investment that shows up in the energy bill and in reduced absenteeism.
She secured R-Zero a seat on the ASHRAE board - the organization that sets indoor air quality standards for North America. That is not a seat companies buy. It is a seat companies earn by demonstrating they are shaping the future of the field. For Nuckles, it is also the kind of move that makes the market: when R-Zero helps write the standards, R-Zero's technology is already built to meet them.
"Our platform is designed to be user-friendly, secure, and scalable, making it accessible to a wide range of users, from building owners to operators to tenants."

On leadership, she draws a line between kindness and niceness - a distinction that matters more than it sounds. A nice manager avoids difficult conversations. A kind manager has them, because protecting someone from feedback is the less caring option. She runs strength-based teams: build on what people do well rather than grinding against what they don't. And on decisions, she moves fast - particularly on talent. The cost of a slow hire decision, in her view, is almost always higher than the cost of the decision itself.
Her personal priorities are three words: education, environment, health. They also happen to be the three main market verticals R-Zero serves - K-12 schools and universities, green buildings and sustainability mandates, hospitals and senior care facilities. Whether the alignment is design or serendipity, it makes the pitch to her team straightforward: what we do at work is what we care about at home. She is the mother of three daughters, each described as working to make the world a better place - which is probably not coincidental.
R-Zero is headquartered in San Francisco, operates across the United States, and targets a customer base that spans corporate campuses, K-12 districts, hospitals, universities, government facilities, and senior care communities. The total addressable market is effectively every building that has people in it. Nuckles is not trying to boil the ocean. She is starting with the buildings where the air quality stakes are highest and working outward from there.
