“The Resource Innovations team is passionate about building a company that creates impact, and that can only come with the growth and scale that this Inc. 5000 list represents.” — Lauren Casentini, Founder and CEO

San Francisco, CA - Inc. magazine announced that Resource Innovations, a women-led energy and environmental consulting company, is No. 15 on its annual Inc. 5000 list. The list represents the most prestigious ranking of the United States’ fastest-growing private companies and is a unique look into the American economy’s most dynamic segment – its independent small businesses. Intuit, Zappos, Under Armour, Microsoft, Patagonia, and many other well-known names gained their first national exposure as honorees on the Inc. 5000.

Based on its strong three-year revenue growth from 2016 to 2019, Resource Innovations also ranked No. 2 in women-led companies, No. 3 in the Energy category, and No. 5 in companies based in California. The firm has multiple locations and staff from coast to coast across the United States, with headquarters in the San Francisco Bay Area and Chicago.

“Ranking at the top of this prestigious list reflects the value that our strategic approach to advancing the clean energy economy is creating,” stated Resource Innovations CEO and founder, Lauren Casentini. “The Resource Innovations team is passionate about building a company that creates impact, and that can only come with the growth and scale that this Inc. 5000 list represents.”

Founded in 2016, Resource Innovations delivers strategic energy optimization programs through utilities and partners to communities and businesses across the United States. With deep roots in designing and implementing utility energy efficiency programs, particularly for hard-to-reach market segments, the company is innovating solutions to address the needs of the evolving energy industry.

Leading the company’s strategy, vision, and growth, CEO Lauren Casentini is a seasoned executive in the energy efficiency industry, with over 30 years of consulting and policy expertise. This is her second company to appear on an Inc. 5000 list; her first energy consulting firm, Resource Solutions Group, ranked 402 in 2011 just prior to its acquisition by a private equity-backed firm, where she served on the Board of Directors and executive team that accelerated the company’s growth to over 3,000 employees. Casentini’s entrepreneurial energy and track record attracted many of the original Resource Solutions Group leadership team to join her in building Resource Innovations.

“We have been fortunate to collaborate with supportive colleagues, clients, and partners who share our vision for transforming the energy industry and for bringing the economic, social, and environmental benefits of the clean energy economy equitably to communities and businesses,” noted Casentini. “The momentum we’ve built over these past three years is generating exciting results to come.”
