Formed to align supply with demand
Ourea capitalized in early 2026 and built a catalyzing team that broadened GravityBank's benefits and features, and expanded its product line.
With support from advisors and partners, Ourea is bringing GravityBank to communities, districts, and facilities in need of grid firming, cooling capacity, and water reserves to offset peak energy demand swings, manage heat output from buildings and data centers, and guard against drought and wildfires.

Adam Semel believes that empowering resilient communities means reaching across sectors and disciplines to drive new solutions. As a Partner at Skidmore, Owings & Merrill (SOM), Adam helps deliver transformative built environment projects around the globe. As CEO and co-founder of Ourea Energy—SOM's first spinout company—he leads the development of novel infrastructure that combines energy storage, thermal management, and water resilience to power the next century.
Steve Ray specializes in charting a path to yes where others see no. An MIT Mechanical Engineering lifer (BS, MS, and PhD), Steve blends rigorous technical expertise with deeply human finesse to empower teams that deliver world-class results in architecture, sustainability, and manufacturing. Previously, he led manufacturing engineering at Rivian and co-led the sustainability practice at SOM, where he pushed the boundaries of sustainability, structures, and architecture for the world's tallest towers.
Brook Rosini has a gift for asking the right questions to bridge the gap between bold ideas and seamless execution. A dual-brained systems thinker, Brook's ability to synthesize information, knack for overcoming organizational inertia, and talent for galvanizing multidisciplinary teams around a shared vision has enabled her to transform work at large institutions like Apple and the Obama Presidential Center.
Bill Baker has redefined the limits of what is possible in the built environment. Widely regarded as one of the most accomplished structural engineers in the world, he led the development of the “buttressed core” structural system for the Burj Khalifa, the world's tallest manmade structure. From honorary doctorates to his role as an Emeritus Professor at the University of Cambridge, Bill's work bridges the gap between classical engineering theory and the most advanced technologies of the 21st century.
Katherine Gajewski believes that complex challenges require engaging as many stakeholders as possible. She built that conviction over six years leading Philadelphia's Mayor's Office of Sustainability, where she helped build one of the earliest integrated approaches to climate, sustainability, and energy management inside city government. She later carried that work forward as a City Scale partner, building cross-sector partnerships and coalitions to advance local climate solutions.
