Impulse Space

About

Impulse Space develops orbital transfer vehicles that function as last-mile transportation infrastructure for satellites and payloads across Earth orbit and beyond. Founded in 2021 by Tom Mueller - the propulsion engineer behind SpaceX's Falcon engine family - the company operates two primary vehicle platforms: Mira, an agile orbital transfer vehicle for maneuvering payloads between orbits, and Helios, a high-performance kick stage designed for LEO-to-GEO transport. The vehicles support mission profiles ranging from LEO Express rideshare services to cislunar and lunar operations, serving commercial, civil, and government customers.

The engineering organization includes veterans from SpaceX, TRW, and other aerospace programs, now numbering approximately 80 employees. Technical work spans propulsion system development, avionics integration, and autonomous control systems for spacecraft operating across multiple orbital regimes. The company has raised over $525 million from investors including Founders Fund and Lux Capital, funding the development and flight validation of its vehicle platforms.

Impulse Space's approach addresses the orbital mobility gap between launch vehicle separation and final operational orbit - analogous to ground transportation's last-mile problem. The vehicles provide delta-v capability and precision maneuvering to position payloads in specific orbits that rideshare launch profiles cannot directly access, expanding operational flexibility for satellite operators and space stations without requiring dedicated launch vehicles for each destination orbit.

SpaceX

In 2002, Elon Musk recognized a fundamental problem with space exploration: the costs were astronomical and rocket technology had remained stagnant for decades. After attempting to purchase Russian rockets and finding them prohibitively expensive, he realized that dramatic cost reductions through reusable rockets were essential for humanity's future among the stars. This insight led him to found SpaceX with the ambitious goal of revolutionizing space technology and ultimately making life multi-planetary. From its humble beginnings in Hawthorne, California, SpaceX has evolved from a disruptive startup into an industry leader that fundamentally changed how we access space. The company achieved what many deemed impossible: developing rockets that can launch, return to Earth, and fly again. By perfecting reusable rocket technology with Falcon 9 and Falcon Heavy, SpaceX dramatically lowered launch costs while increasing reliability. Today, the company not only delivers cargo and astronauts to the International Space Station but also operates the world's largest satellite constellation with Starlink, all while pushing toward the ultimate goal of establishing a self-sustaining city on Mars.

Lodestar Space

We're building the first autonomous AI fighter-pilot for space to protect the critical infrastructure that orbits our planet. Our flagship product, Mithril, is a hardware-agnostic autonomy software suite that can turn any off-the-shelf spacecraft into an intelligent bodyguard satellite capable of detecting, characterizing, and responding to orbital threats in real-time. The space domain is getting crowded and contested - from anti-satellite weapons to debris collisions - and we believe the best defense is having capable guardians already on station, watching over high-value assets 24/7. Our team combines deep expertise in machine learning, robotics, and aerospace engineering to tackle a genuinely hard problem: making spacecraft that can think and act autonomously in the harsh, unpredictable environment of orbit. We're not just building algorithms - we're developing end-to-end protection services that integrate seamlessly with existing satellite buses and deliver practical defensive capabilities to commercial and government operators. It's challenging, technical work that matters, and we're growing fast to meet the moment.

Genesis AI

In 2025, Zhou Xian and Théophile Gervet recognized a fundamental bottleneck in the robotics field: while digital AI had made extraordinary progress, physical AI - the intelligence enabling machines to perceive, understand, and interact with the real world - lagged dramatically behind. Physical labor contributes an estimated $30-40 trillion to global GDP, yet over 95% remains unautomated because current robotic systems rely on brittle, rigid, and overfitted software stacks that are narrow in scope, costly to deploy, and impossible to scale. They founded Genesis AI to bridge this gap, assembling a team of world-class talent from Mistral AI, NVIDIA, Google, CMU, MIT, Stanford, Columbia, and UMD. Their vision: build a universal robotics foundation model and horizontal robotics platform that would unlock unlimited physical labor. Genesis would achieve this through a scalable data engine fusing real-world robot interaction with high-fidelity physics simulation, an open-source ecosystem to accelerate field-wide progress, and robust robot deployments thriving in messy, unconstrained environments. With $105 million in seed funding from Eclipse Ventures and Khosla Ventures, Genesis emerged from stealth in July 2025 to build what's next in physical AI.
