NineDot Energy Selected as a Crain's 2025 Best Places to Work in NYC Company

“It’s an honor to make the list again,” said David Arfin, NineDot Energy CEO and Co-founder. “For us, being selected reflects our deep commitment to building a company culture of meaning, impact and inclusion, and we’re proud of the team we’ve created and the work we do. As Crain’s noted, ‘serious investment in people fuels long-term performance’. With volunteer days and employee stock options, scavenger hunts and 100% paid parental leave, we’ve invested in our employees’ health, wellness and growth from day one.”

The selection process for the Crain’s list is rigorous: a company needs to complete a lengthy application and self-evaluation, and the employees need to complete a fully anonymous extensive engagement survey seeking information about their work and workplace culture, including professional development, work-life balance and benefits. Only then does Crain’s select those companies that make the annual list, in collaboration with the Workforce Research Group.

Fred Polirer, NineDot’s Vice President People and Culture, said “We’re honored to be included on this list again and want to thank Crain’s for recognizing the quality of our team, our culture and our work. When we first applied in 2023, we were a startup with 30 employees. We’ve grown substantially since then, and today have 80 full-time members of our team, so we decided to apply again. Beyond the validation from a respected third-party, what makes this award extra special is that a critical element of being selected was what this larger group of employees said about us. They voiced how they feel about the work they do, the people they work with, and the work environment of NineDot overall. We're proud to have such a strong, engaged and dedicated team executing our mission.”

This is the second workplace award NineDot received this year. In May, NineDot’s People Operations team was recognized as the winner of the New York Battery Energy Storage Technology Consortium’s initial Inclusive Energy Storage Workforce award for its leadership in building an inclusive clean energy workplace. Through initiatives such as equitable hiring practices, cultural heritage celebrations, innovative social programming, and strategic internships, the company has embedded inclusive practices in a variety of ways throughout its daily operations. All these initiatives directly support NineDot’s business, with seven operating projects at four locations in Staten Island and The Bronx totaling 26MW currently, and a goal of having 400MW of battery storage in development, construction or operation by the end of 2026.

NineDot is grateful to its extraordinary employees, dedicated partners, engaged and supportive communities, agencies, regulators, investors and financiers who provide the ecosystem that allows us to do such meaningful work.
