Brown and White Ventures Backs Stak Mobility to Rethink Urban Infrastructure

Rochester, N.Y. - Brown and White Ventures has announced a new investment in Stak Mobility, a company focused on reshaping how cities use space, energy, and transportation infrastructure.

The announcement signals continued momentum for the Upstate New York-based venture firm, which is actively investing in companies tackling large-scale, system-level challenges across industries.

Stak Mobility is building what it describes as a new model for urban infrastructure—one that combines real estate optimization, electric vehicle (EV) charging, and energy management into a single platform. At the center of that model is a vertically integrated EV carousel system designed to significantly reduce the physical footprint of traditional parking.

By stacking vehicles vertically, the system can reduce parking space requirements by up to 85%, according to the company. That shift opens up valuable land in dense urban environments for higher-use applications, including housing, retail, and mixed-use development.

The approach comes at a time when cities across the U.S. are facing converging pressures: limited land availability, rising housing demand, aging energy infrastructure, and a growing transition toward electrification.

“Stak Mobility is building a category-defining platform that addresses some of the most pressing challenges facing modern cities,” said Jim Aroune, general partner at Brown and White Ventures. “Their approach combines hardware, software, and energy systems into a unified, capital-efficient model that aligns with how urban environments are evolving.”

Stak operates at the intersection of three rapidly changing sectors, real estate, mobility, and energy. Its platform is designed not only to store vehicles more efficiently, but also to support EV charging and distributed energy services, positioning parking infrastructure as part of a broader urban energy network.

Founder and CEO Diallo Powell said the investment will help accelerate the company’s next phase of growth.

“We are grateful for Brown and White Ventures’ belief in our team and our vision,” Powell said. “It’s great to have this fund on board.”

The company’s business model is structured to reduce upfront capital risk for developers and property owners, while generating recurring revenue through software, services, and energy management. By embedding its systems into both new and existing developments, Stak aims to improve long-term asset value while preparing properties for the adoption of electric and autonomous vehicles.

Stak has already begun deploying its technology across multiple U.S. markets, with projects spanning multifamily housing, retail, hospitality, and mixed-use developments. The company also reports a growing pipeline supported by partnerships across real estate, utilities, and mobility sectors.

“As cities face increasing pressure on land use and energy infrastructure, Stak Mobility is positioned to become a critical layer in the next generation of urban systems,” Powell said.

The new funding will be used to expand into additional high-density metro markets, further develop its software and energy platforms, and scale sales, operations, and project delivery. The company also plans to advance its work in distributed energy and grid integration.

For Brown and White Ventures, the investment aligns with its broader strategy of backing high-growth companies with regional ties and long-term impact potential. The firm focuses on healthcare, manufacturing, and technology-driven startups, with a particular emphasis on supporting founders from underserved communities and companies based in Western New York and the broader Upstate region.

“Brown and White Ventures is proud to partner with Stak Mobility as it builds the future of intelligent and sustainable cities,” Aroune said.

As urban centers continue to evolve, investments like this highlight a growing focus on infrastructure solutions that don’t just solve one problem, but instead rethink how entire systems work together.
