Summary
The week ending August 1, 2026 delivered significant venture capital deployment across US startup ecosystems, with 28 notable funding rounds generating $2.2B in new equity capital. The activity reflects continued institutional appetite for climate technology, advanced manufacturing, and space-based infrastructure solutions.
Antares Industries, founded in 2023 by Jordan Bramble and Julia DeWahl, secured $370M in fresh funding for its transportable nuclear fission microreactor business. The Los Angeles-based manufacturer designs reactors for both terrestrial and space applications, positioning itself at the intersection of nuclear innovation and emerging space economy demand. With this round, Antares has accumulated $471M in total equity funding from a syndicate including Caffeinated Capital, Industrious Ventures, Paradigm, Point72 Ventures, and Shine Capital—a roster indicating strong conviction from both generalist and sector-focused venture firms.
Antora Energy, a thermal energy storage developer based in San Jose, attracted even larger capital commitments with a $550M funding round. Founded in 2018 by Andrew Ponec, David Bierman, and Justin Briggs, Antora has now raised $750M in total equity. The company's heat-based energy storage systems target industrial renewable energy applications, addressing a critical bottleneck in decarbonization infrastructure. Its investor base—spanning Breakthrough Energy Ventures (the Bill Gates-backed climate fund), Lowercarbon Capital, Salesforce Ventures, and other institutional players—signals strong market validation for thermal storage as a core enabling technology in the energy transition.
Array Labs, a Palo Alto-founded geospatial intelligence company established in 2019, raised $21M during the same period. The firm develops space-based radar systems and delivers 3D Earth imagery services to commercial and government clients. These three deals exemplify the broader capital concentration in deep-tech sectors addressing climate, energy infrastructure, and space applications—categories that have sustained venture funding momentum despite broader market volatility.
