Portal Space Systems is a Seattle-based space start-up solving the need for mobility in space. Our flagship product, the Supernova satellite bus, is engineered for rapid and long-range in-space maneuverability. Our payload-agnostic, 500 kg spacecraft features a novel solar-thermal propulsion system, which enables an ultra-high delta-v, a 50X improvement over existing products on the market. The company was founded in 2021 by industry leader Jeff Thornburg, alongside COO Ian Vorbach and VP of Engineering Prashaanth Ravindran. We are on a mission to empower the next generation of space operators to maintain space superiority.

At Multiscale AI, we’re revolutionizing semiconductor manufacturing with advanced, agentic AI and digital twins. We partner with leading semiconductor manufacturers to tackle their most complex Semiconductor Manufacturing Technology Optimization (SMTO) challenges. Our platform combines Bayesian digital twins, purpose-built ML models, and AI agents to extract actionable insights from limited silicon data and physics simulations. By unifying fragmented data, delivering domain-optimized ML, and enabling scalable, fab-ready applications, we help customers reduce costly silicon trials, speed up innovation cycles, and optimize fab processes at scale. Our team brings together experienced scientists, AI/ML engineers, software developers, and materials experts, united by a commitment to build comprehensive, reliable, and scalable solutions that make semiconductor manufacturing more efficient, intelligent, and competitive.

We invest in early-stage companies solving the world’s problems through deep tech across the climate, energy, manufacturing, robotics, and space domains 🤖 🦾. The sci-fi future will be automated. We are based in Boston and NYC and are part of the team at AlleyCorp.

Going deep on the technologies shaping the next 30 years. Hosted by Brannon Jones and Abe Murray at AlleyCorp.
