Owen Barrett

Co-Founder & President

Since earning a bachelor’s degree in finance, cutting his teeth in the financial industry, and earning a master’s degree in environmental science and management, Owen’s been on a professional rampage, pushing complacency and bureaucracy aside and decarbonizing our economy at an impressive rate.
As a Global Energy Manager for a Fortune 500 company for three years, Owen implemented $60 million of clean technology. Combining his experience in fuel cells, solar PV, energy storage, LED lighting, and HVAC optimization, Owen left to launch lumeo, a niche ESCO. Within three years, lumeo hit eight figures in revenue and helped forty school districts implement energy efficiency and renewable energy.

After a successful exit from lumeo, Owen looked for his next opportunity. After nearly a decade in the clean technology industry, Owen concluded there’s too much attention given to developing new clean technologies and not enough focus on rapid deployment of existing technology. It doesn’t matter how efficient a solar module is if only 3% of American buildings have them installed.

Owen started ZNE Capital and pivoted to buying commercial real estate for the purpose of decarbonizing it. In just three years, Owen acquired and partially decarbonized $96M of multifamily properties. While ZNE Capital proves to have a successful business model, the rampant inauthenticity within the institutional impact investing space made it challenging for ZNE Capital to make impact at scale.

Owen founded Rayven to decarbonize existing buildings at scale. Rayven is the world’s first net zero real estate investment platform. Every property we buy is converted to true net zero (no offsets involved). By partnering with thousands of authentic, retail impact investors, Rayven, and every single investor will decarbonize the world, one apartment building at a time.

Grant Bowman

Co-Founder & Senior Vice President

Grant brings a wealth of experience across the sustainable energy and real estate landscapes to ensure Rayven continues to grow a high-impact portfolio that delivers maximum value.
In addition to his leadership role at Rayven, Grant is also Senior Vice President at ZNE (Zero Net Energy) Capital, the first multifamily sponsor to enhance returns on the traditional value add model through the rapid deployment of solar panels on projects across the U.S. During his time with ZNE, Grant scaled portfolio growth and institutional partnerships with capital groups.

Previously, he worked for the energy services and performance contracting firm McKinstry on energy and water efficiency retrofits. He helped clients identify financially viable retrofit measures and capture all available utility rebates and grants.

As a true environmentalist, Grant is only willing to work with firms that have a deep positive impact. This is apparent from his time as an environmental science teacher at Seattle Academy, as well as his time as an environmental volunteer in Peace Corps. During his service, he established a profitable ecotourism business in the Congo River Basin, employing poachers to provide them with a financial incentive to not hunt endangered animals.

Grant holds a B.A. in Economics and Environmental Studies from Western Washington University and a Master in Teaching from the University of Washington.

Earl Mohler

Co-Founder & VP Solar

Earl worked in general construction from 1998 – 2009, when he began working for Absolutely Electric, Inc., and decided to specialize in electrical work. At that point, Earl was introduced to residential solar and realized the importance of energy efficiency and energy independence. By 2010, Earl became a licensed commercial journeyman electrician in California working on everything electrical-related, from residential to industrial.
In 2011, Earl started Mohler Electric and became a C-10 electrical contractor. The following year, Earl added a C-46 solar contractor classification to his license and changed the company name to Mohler Solar. Earl is also CALCTP certified in energy-efficient lighting and lighting controls. At this point in his career, Earl designed and installed over 200 solar installations sizes ranging from 5 kW to 75 kW, and had implemented lighting upgrades for a combined annual savings of over 3,000,000 kWh.

As the residential market became increasingly competitive, Earl decided to pursue commercial installations with lumeo. Earl worked with over 40 school districts across California upgrading lighting and installing solar to help reduce operating expenses. Since then, Earl switched gears again, and for the past two years, has focused on small utility-scale installations in the multifamily sector. For Earl, the jump to small utility-scale projects was his next logical progression in the industry. Earl could apply everything he learned from the non-profit sector to the multi-family space, greatly reducing and sometimes removing the operating expense of electricity. Earl’s multifamily projects have ranged from 75 kW – 700 kW-DC. Earl has overseen the design, engineering, construction, and utility interconnection.
