Steve Bisset
Steve Bisset is an Australian-born engineer and serial founder who has built two companies four decades apart in two different industries. In the 1970s he left an 18-month stint at Intel - where his first assignment was finding the first working 8080 chip in a tray of parts - to start Megatest out of his bedroom with $10,000 of vested stock and a housemate from Caltech. Megatest grew into a semiconductor test equipment company, survived the 1985 industry collapse that cut it from 450 people to about 200, listed on NASDAQ in 1993, and was acquired by Teradyne in 1995 for $245 million. In 2009 he co-founded Terrajoule, now Terrajoule Energy Inc. in Palo Alto, on a deliberately unfashionable premise: pair concentrated solar heat with pressurised hot-water storage and a reciprocating steam engine, a machine nobody had manufactured commercially since the 1950s. Terrajoule raised an $11.5 million Series A in 2013 led by New Enterprise Associates with Air Liquide, and Bisset continues to pursue low-cost dispatchable solar as an alternative to PV-plus-battery, with work extending into India.
Tina Boville
Tina Boville is the co-founder and CEO of Aralez Bio, a Berkeley-based biotechnology company using directed evolution to make noncanonical amino acids - the building blocks behind a growing share of modern medicines. A biochemist trained at the University of Colorado and Caltech, where she worked in Nobel laureate Frances Arnold's lab, Boville turned an engineered enzyme platform into a company that can produce over 100 amino acids in single-step reactions, cutting manufacturing waste by up to 99%. She has been named to MIT Technology Review's Innovators Under 35, is an Activate Fellow, and in 2024 raised a $12 million Series A to scale production to tons per year.
Calcarea
Calcarea is a Caltech- and USC-born climate-tech company decarbonizing the shipping industry with onboard reactors that capture CO2 from ship exhaust and convert it into stable ocean bicarbonate. By speeding up the natural reaction between seawater and limestone - a process that normally takes over 10,000 years - down to about a minute, Calcarea aims to permanently and safely store roughly half of a cargo ship's emissions as slightly saltier seawater, at costs competitive with today's best carbon capture options.
James Rebesco
James (Jim) Rebesco is the co-founder and CEO of Striveworks, an Austin-based AI company that helps the U.S. defense and national-security community build, deploy, and monitor machine-learning models at scale through its Chariot platform. A physicist by training (Caltech) and a computational neuroscientist by doctorate (Northwestern), he spent seven years as a partner at high-frequency trading firm Virtu Financial before turning to operational AI. Under his leadership Striveworks has landed a $70M enterprise government agreement, raised a Series B led by Washington Harbour Partners, and become the first company to bridge the U.S. Army's two largest battlefield AI efforts.
Jess Adkins
Jess Adkins is a Caltech chemical oceanographer turned founder-CEO of Calcarea, a climate-tech startup that bolts a limestone-and-seawater reactor onto cargo ships to scrub up to half their CO2 and lock it away as ocean bicarbonate. After two decades studying how the deep ocean naturally buffers carbon, he spun his lab science out of the garage during COVID to attack shipping's gigatonne-a-year emissions problem at a fraction of the cost of atmospheric capture.
Emma Qian
Emma Qian is the co-founder and CEO of Nova Intelligence, a San Francisco startup building an agentic AI platform that analyzes, modernizes, and generates custom code for SAP systems. A former research engineer at Google DeepMind and software engineer at Meta AI, Caltech-trained Qian left frontier AI research to attack one of enterprise software's least glamorous and most expensive problems: the migration of decades of custom SAP code to S/4HANA. Nova has raised over $40 million, including a $31.5 million Series A led by Chemistry with backing from Accel, Conviction, and SAP.io, and counts customers like Festo who report working roughly five times faster. She is a Forbes 30 Under 30 honoree.
Hrant Gharibyan
Hrant Gharibyan is the co-founder and CEO of BlueQubit, a San Francisco quantum-software-as-a-service startup he launched in 2022 with Hayk Tepanyan. A theoretical physicist trained at MIT, Stanford (PhD under Leonard Susskind), and Caltech (in John Preskill's group), he co-authored a wormhole-teleportation algorithm that Google Quantum AI later ran on a real superconducting processor. BlueQubit builds GPU-accelerated emulators and a cloud platform that lets enterprises design and run quantum algorithms, and raised a $10M seed round in December 2024 led by Nyca Partners.
Schuyler Cullen
Schuyler Cullen is the co-founder and CEO of Summer Robotics, a Campbell, California machine-vision company building Kortx, a camera-free perception system that uses lasers and event sensors to give robots animal-like sight at 100Hz, 100-micron precision, and 20ms reaction time. A theoretical physicist by training with a Caltech double major and a Stanford PhD in string theory, Cullen spent two decades turning hard math into shipping technology - co-founding the video-recognition startup Keystream and leading AI and Robotics at Samsung, where he built the autonomous-mobility stack for the company's robots and cars. In 2025 Summer Robotics raised a Series A led by Applied Ventures, the venture arm of Applied Materials.
AJ Abdallat
AJ Abdallat is the founder, chairman and CEO of BeyondAI (formerly Beyond Limits), a Glendale, California enterprise AI company that commercializes cognitive artificial intelligence born inside NASA's Jet Propulsion Laboratory and Caltech. A serial entrepreneur who spent more than a decade incubating Caltech/JPL spinouts, Abdallat built Beyond Limits around the idea that AI which guided the Mars Rovers and Voyager probes through deep space can run mission-critical industrial operations on Earth - in energy, utilities, manufacturing and healthcare - while explaining the reasoning behind every decision.
Dave Licata
Dave Licata is a Stanford-trained mechanical engineer turned biotech operator who co-founded TORL BioTherapeutics with legendary UCLA oncologist Dennis Slamon.
