Relativity is building humanity’s multiplanetary future. We invented a new approach to design, build, and fly our own rockets, starting with Terran 1 – the world’s first entirely 3D printed rocket, and Terran R, our next generation medium-heavy lift fully reusable launch vehicle. As a vertically integrated technology platform, Relativity is at the forefront of an inevitable shift toward software-defined manufacturing. By fusing 3D printing, artificial intelligence, and autonomous robotics, we are pioneering the factory of the future. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. We believe in a future where interplanetary life fundamentally expands the possibilities for human experience. Our long-term vision is to upgrade humanity’s industrial base on Earth and on Mars.

At Serif Health, we are taking the complexity out of the cost of healthcare. Our mission is to make healthcare pricing and contracting more transparent, easier to understand, fairer, and ultimately more affordable for all. New price transparency regulations have made a wealth of healthcare pricing and reimbursement data publicly available for the first time, but it is still extremely hard to ingest, organize, and actually use this data to understand the cost of care. That’s where we come in. Serif Health is building healthcare price intelligence data products and APIs to power the future of more transparent healthcare. We are an early-stage, venture-backed startup with a small, collaborative team of healthcare experts, engineers, and designers. We are excited to add new team members motivated by our mission, passionate about making a difference in healthcare, and looking forward to learning and growing from the challenges we will face along the way!

With five issued patents covering our core business lines, and more than a dozen additional patents pending this year and more than $5M in revenue, TransAstra is developing the technologies that will drive the rapidly expanding space economy. Our breakthrough Omnivore propulsion system can propel spacecraft, including our Worker Bee commercial OTV with water or virtually any other fluid as a propellant using only concentrated sunlight as a power source. Omnivore is faster, cheaper, and more practical than electric propulsion while being substantially less expensive, safer, and more operationally flexible than legacy chemical propulsion systems. Our Sutter Telescope System can identify and locate resource-rich asteroids and orbital debris that existing technologies can’t find and works synergistically with our Worker Bee OTV for orbital logistics. For government customers, Sutter can identify dark fast-moving objects between Earth and the Moon which currently evade detection, a critical issue for national defense and a key need of the Space Force. We are already using Sutter in ground-based observatories and will begin commercial sales of Sutter SDA data next month having tracked dozens of faint moving objects in space already. Once launched into space, Sutter will be 300,000 times more cost effective than any other known telescope design and will revolutionize sense making in space.

Turion Space is building spacecraft to move things around in space and image space objects when they’re not, and focused on developing the dual-use technology required to ensure a sustainable future in space.

The founding team originates from SpaceX, and after going through the Y-combinator accelerator in summer 2021 went on to raise a $6.2M seed round and is launching their first DROID satellite in early 2023.

Auto parts retailers get product data from hundreds of manufacturers that is inaccurate and inconsistent, often with big gaps in key values. They currently have a team of "catalog managers" who are required to process and enhance this data line by line, resulting in a week to months long lag between receiving product data and actually being able to start generating revenue from those products. Versable leverages AI to scan the web for tens of millions of auto parts listings, and uses a fine-tuned LLM with RAG to instantly process, enhance, and transform data. With just a part number, Versable is able to generate market-ready titles, product descriptions, and specs, in any format that's needed.
