Rocket engine startup Impulse raises $500 million to hire people, not AI

Curated by Shubham · TechCapsules · Jun 2, 2026

AI-summarised brief · reviewed before publication

Impulse Space, a startup founded by Tom Mueller, has announced a $500 million Series D funding round to hire up to 200 new employees. The company, focused on in-space mobility, will use the funds to build and test more space vehicles, including its Mira and Helios platforms. Impulse is targeting U.S. Space Force buyers and plans to expand its team despite the current demand for aerospace talent. The funding round was led by 137 Ventures and BANNER VC, with participation from other investors. Impulse emphasizes the importance of human engineers in solving real-world problems, rather than relying on AI.

💡 Why It Matters

· Human expertise is still essential in spacecraft design, as AI tools struggle to replicate the complexity of real-world engineering problems.
· Impulse's approach highlights the limitations of AI in hardware design, where training data is scarce.

SpaceX alum nabs $22M to turn rocket engines into geothermal power plants

Critical Energy, a startup founded by SpaceX alum Spencer Jackson, has raised $22 million to develop modular turbines for geothermal power plants. The company aims to fill a gap in the market by providing turbines tailored to geothermal power plants, with the funds earmarked to build its first 2.5 megawatt project. Geothermal energy has significant potential, with at least 42 terawatts of capacity available worldwide, and Critical Energy hopes to play a key role in its development. The startup's modular turbines are designed to be built in a factory, reducing assembly time and costs. The first power plant using Critical Energy's turbines is scheduled for completion by 2027.

💡 Geothermal energy could beat nuclear fission and fusion to commercial deployment, with Critical Energy's modular turbines potentially enabling gigawatt-scale power plants by the early 2030s. Advanced geothermal could also power nearly two-thirds of new data centers by 2030, addressing the tech industry's growing energy needs.

Pramaana Labs raises $27M seed round from Khosla Ventures to bring formal…

Pramaana Labs has announced a $27 million seed funding round led by Khosla Ventures, with participation from several other investors. The startup aims to bring formal verification to AI, focusing on sensitive verticals like law, drug discovery, and tax preparation where errors can be costly. Pramaana's system combines a conventional large language model with a deterministic layer, using the open-source LEAN programming language to verify mathematical proofs. The company will build formal verification systems for each use case, overseen by domain experts, to ensure reliability and accuracy in AI deployments. This approach draws on the tools of mathematical formalization.

💡 By codifying rules and regulations into executable code, Pramaana Labs can provide stronger protections against AI errors and hallucinations. This deterministic approach can ensure that AI decisions are reliable and trustworthy, especially in high-stakes domains.
