Sujeet Kumar
Sujeet Kumar is the co-founder and CEO of Ionblox, a Fremont, California battery company building pre-lithiated silicon-anode lithium-ion cells for electric vehicles and electric aviation. A materials scientist with a Ph.D. from the University of Rochester and more than 60 patents to his name, he previously served as CTO of Envia Systems, where his team developed one of the first 400 Wh/kg lithium-ion cells with a silicon anode. Ionblox, formerly Zenlabs Energy, has raised roughly $32 million in Series B funding from backers including Lilium, Applied Ventures, Temasek and Catalus Capital, and markets cells that promise higher energy density, up to five times more power, and 10-minute fast charging.
Ionblox
Ionblox is a Fremont, California battery company building high-energy, high-power lithium-ion cells around a proprietary pre-lithiated silicon (SiOx) anode. Spun out of the earlier Zenlabs Energy effort and rebranded in 2022, the company targets two demanding markets - electric vehicles and electric aviation (eVTOL) - with cells that it says exceed 330 Wh/kg and can charge to roughly 60% in five minutes while holding up past 1,000 cycles. Backed by eVTOL maker Lilium, Applied Ventures, Temasek and Catalus Capital, Ionblox has raised about $32M in Series B funding and holds more than 40 patents.
Qnovo
Qnovo is a Milpitas, California software company that makes lithium-ion batteries smarter. Its intelligent battery management platform - powering SpectralX adaptive fast charging and SentinelX safety diagnostics - is embedded in more than 150 million smartphones and increasingly in EVs from the world's top automakers, helping prevent fires, extend range, and stretch battery life.
Arc
Arc is a Los Angeles electric boat company building battery-powered watercraft from the ground up - software, motors, battery packs and hulls - rather than retrofitting gas boats. Founded in 2021 by veterans of SpaceX, Rivian and Tesla, Arc started with the high-end Arc One, found its commercial footing with the Arc Sport electric wake boat and the Arc Coast center console, and is now extending its propulsion stack into commercial and defense vessels including electric and hybrid tugboats. The pitch: quiet, fume-free, low-maintenance boats with the torque and software experience of an EV.
Arch Rao
Arch Rao is the Founder and CEO of SPAN, a San Francisco-based clean energy hardware company that reinvented the home electrical panel. A Stanford-trained mechanical engineer and former Tesla Energy leader who helped launch Powerwall, Powerpack, and SolarCity products, Rao founded SPAN in 2018 with a singular mission: rapidly decarbonize American homes by making the century-old electrical panel smart. SPAN's intelligent panels enable circuit-level control, real-time energy monitoring, solar and battery integration, and grid demand response - turning a neglected utility box into the command center for home electrification. With over $522M in total funding and backing from Wellington Management, Fifth Wall, Robert Downey Jr.'s FootPrint Coalition, and Amazon's Alexa Fund, SPAN is building the grid-edge infrastructure layer for the coming decades of home electrification.
Keven Wang
Keven Wang is the Co-Founder and CEO of UnitX, a Santa Clara-based AI robotics company transforming industrial quality control through machine vision. A Stanford computer science alumnus with roots in SalesforceIQ engineering, Wang founded UnitX in 2018 alongside Adam Yang and Weixiong Zheng. The company has since deployed 820+ AI inspection systems across 135+ factories worldwide - inspecting $6.1B worth of products annually - and raised $92M in total funding. UnitX's flagship platforms (FleX, GenX, OptiX) help automotive, EV battery, and electronics manufacturers cut defect escapes by 9x and reduce scrap rates by up to 50%, with a philosophy Wang distills as: 'automate everything and maximize human intellect.'
