Built on the Stateful platform, BrightAI empowers operators of critical infrastructure to collect and connect sensor data in real time, uncover hidden insights, and make smarter decisions. From predictive diagnostics and autonomous robotics to digital twins and AI-enabled workflows, BrightAI solutions serve industries including water, power, gas compression, pest control, HVAC, and manufacturing. By turning complex physical signals into actionable intelligence, BrightAI is redefining how essential services are delivered and sustained.

Apex was founded to solve one of the space industry’s biggest challenges: the satellite production bottleneck. While reusable launch vehicles have solved many orbital access challenges, scaled satellite manufacturing remains a critical bottleneck to constellation deployment. Apex’s solution: productized, configurable spacecraft designed for manufacturing and delivered at scale.

 Our three product lines — Aries, Nova, and Comet — serve a broad range of customer missions through configurable designs optimized for operations from LEO to GEO. These platforms will ensure the U.S. and its allies maintain a strategic advantage in the New Space Race, providing the foundation for today’s most critical constellations and tomorrow’s next-generation architectures. ‍ Today, Apex is delivering standardized satellite buses at scale by blending traditional aerospace techniques with new space mentalities and lessons from high-rate terrestrial manufacturing. Since our founding, our focus remains the same: short lead times, constellation-scale production, and highly reliable spacecraft. We can’t wait to see what you build on Apex’s platforms. Lets get to orbit.

Stealth startup working to revolutionize clean energy.

Efficient is building the world’s most energy-efficient general-purpose processor by combining ultra-efficient hardware with an intuitive, developer-friendly compiler and software stack that unlocks 10–100× efficiency gains across every part of an application, including AI. Efficient was founded in 2022 to commercialize a breakthrough in efficient computation developed over nearly a decade by a team of world-leading computer architects. Efficients world-class team has produced two silicon implementations of the Fabric architecture: the Electron E0, a prototype system-on-chip, and the Electron E1, the first silicon product. With Efficients cutting-edge effcc Compiler and software stack, the Electron E1 processor has been delivered to customers as of mid-2025, ramping to large-scale volume and distribution in 2026. Efficient already has customer traction in areas such as physical AI for infrastructure and automation, space and defense, automotive, and consumer products. Efficients technology scales from tiny “beyond the edge” devices to large-scale robotics, autonomy, edge cloud, and datacenter applications—enabling widespread adoption across multiple industries and positioning Efficient as the solution to the energy problem across all of computing.

We believe travel has a uniquely powerful ability to bring people together and change the way we see the world - something we believe the world needs more of right now. To quote Terry Pratchett in a Hat Full of Sky: "Why do you go away? So that you can come back. So that you can see the place you came from with new eyes and extra colors. And the people there see you differently, too. Coming back to where you started is not the same as never leaving." The challenge is that travel is hard. The pandemic has made it even more challenging. It can feel like you need a degree in logistics to plan more than a simple trip. Travel is also deeply personal and human. Review sites and booking engines make the actual process of booking easy, but are case studies in the paradox of choice. Information overload results in countless hours of research and a lingering feeling of uncertainty: how similar to me are these reviewers? If you havent worked with a travel agent, you might think of them as a relic of the past. Its true, that agents today are no longer a requirement to book a ticket like they once were. Instead, travel advisors (as theyre now called) act more as a trusted advisor combining local knowledge and experience with their understanding of your values and priorities to craft the perfect trip. The technology that powers the modern travel advisor hasnt kept up with the tools available to consumers. Advisors are left juggling multiple antiquated and fragmented systems. Not only is this frustrating, but it comes at a real cost of business. Disconnected systems can result in lost commissions and a compromised traveler experience. Tern exists to change this by building an integrated platform that connects the modern travel advisor to their travelers and suppliers.
