Twilio Co-Founder’s Fusion Startup Secures $450M Funding Boost
Inertia Enterprises, a fusion power startup co-founded by Twilio's Jeff Lawson, has raised $450 million in a Series A funding round led by Bessemer Venture Partners, with participation from GV, Modern Capital, and Threshold Ventures. The company aims to build a grid-scale power plant using advanced laser technology developed at Lawrence Livermore National Laboratory's National Ignition Facility (NIF). Inertia's laser technology differs from NIF's by being more cost-efficient and scalable. This investment is part of a growing trend in fusion energy funding, with companies like Commonwealth Fusion Systems and TAE Technologies also raising significant amounts recently.
Significant investment in fusion energy startups suggests strong momentum and investor confidence in the potential of fusion technology to revolutionize energy production.

Invertix joins Y Combinator for AI energy infrastructure
Munich-based startup Invertix, which develops AI to operate energy infrastructure, has been accepted into Y Combinator's Fall 2026 batch just seven months after its founding. Founded in February by CEO Joseph Perrotta and CTO Kaan Durmaz, the company addresses the energy transition's bottleneck of skilled staff shortages by building on large AI models with its own layer trained on energy operations. Invertix has four pilot projects, including with TotalEnergies On, and has contracted over 50 GW of renewable capacity with a sales pipeline exceeding 100 GW. The startup raised a €1.7 million pre-seed round in May led by Vireo Ventures. As part of YC's standard deal, it receives $500,000, joining a select group of European energy AI firms in the accelerator.
Helion's Fusion Reactor Hits 150 Million Degrees Celsius!
Helion, a fusion energy startup based in Everett, Washington, reported that plasmas in its Polaris prototype reactor reached 150 million degrees Celsius, about three-quarters of the temperature it says is needed for a commercial plant. Polaris is operating on deuterium-tritium fuel; Helion says this makes it the first fusion company to do so. The company uses a field-reversed configuration and a direct electricity-recovery approach that harvests current induced by fusion magnetic fields rather than extracting heat. Helion raised $425 million last year and has a contract with Microsoft to sell electricity starting in 2028 from a larger 50‑megawatt reactor, Orion, currently under construction. The company aims to reach 200 million degrees Celsius and plans a long-term fuel cycle that incorporates deuterium–helium-3.
