Orion offers a smart mattress cover that continuously tracks a sleeper’s biometrics and automatically heats or cools specific zones to maintain an optimal temperature cycle throughout the night, aiming to improve both deep sleep and REM quality. The product combines embedded sensors with an AI engine that personalizes temperature adjustments for each individual. Seed funding proceeds will be directed toward expanding operations and widening the company’s market reach. Orion was founded by Harry Gestetner and Daniel Gestetner—entrepreneurs behind Fanfix and Byte—and joined by Blake Johnson and Scott Cohen, also from Byte. While the company has not yet disclosed revenue or user metrics, its founding team’s prior ventures recorded sizeable exits, indicating seasoned execution capability. Los Angeles, CA serves as Orion’s headquarters, giving the company access to both the region’s hardware talent and consumer-tech ecosystem.

Somnee builds an AI-powered neurotech headband that uses proprietary EEG+ and AI technology to map brain activity and deliver personalized, non-invasive stimulation to guide users into deeper, faster sleep. Clinical study results reported faster sleep onset (twice as fast), over 30 minutes longer sleep, and a one-third reduction in tossing and turning; the company says it outperforms melatonin, CBT‑i, and Ambien in those measures. Its therapeutic approach is backed by clinical studies and covered by 24 patents. Somnee is preparing to launch a second-generation headband and a SmartSleep AI operating system that enables personalized brain mapping, real-time monitoring, and AI-powered interventions throughout the sleep cycle. The second-generation product is in beta pilots with select NBA teams and performance staff, and the company has partnerships with Equinox Hotels and NBA programs. Somnee has relocated manufacturing out of China and expanded teams in Berkeley and India as it scales to address the sleep-aid market.

Terradot develops and deploys enhanced rock weathering (ERW) to remove CO₂ by spreading finely ground rock on agricultural land and building MRV tools and a digital platform to scale the approach. The company has run scaled pilots in Brazil, spreading over 48,000 tons of rock across 1,800 hectares and reporting promising early results on tropical weathering rates. Terradot has sold nearly 300,000 tonnes of CO₂ removal through signed agreements, including a 90,000-tonne, $27M purchase facilitated by Frontier and a separate 200,000-tonne purchase by Google for 2029 and beyond. The startup is partnering with EMBRAPA and Brazilian industry, government, and academic partners to develop scalable ERW frameworks and leverage local agricultural and quarry proximity. It is building MRV capabilities using soil-core measurements, reactive transport models, geostatistics, and watershed-level measurements to enable high-quality, lower-cost quantification at scale. The founding science and operations team is drawn from Stanford and national labs, and the company intends to commercialize ERW at gigaton scale within the decade.
