Stephen Klein
Stephen Klein is the co-founder and CEO of Hyphen, a San Jose food-robotics company that builds the automated Makeline - a hybrid manual-and-robotic assembly system that runs beneath the counter to build bowls and plates at up to 350 meals per hour. A self-described foodservice fanatic since childhood, Klein started a text-to-order frozen yogurt business in college, helped scale Instacart in its early days, and ran operations at robotic coffee bar Cafe X before launching Hyphen in 2020 with co-founder Daniel Fukuba. Hyphen has since drawn investment from Tiger Global, Chipotle and Cava and deployed systems with chains and foodservice operators across the country.
Tarique Mustafa
Tarique Mustafa is a Silicon Valley cybersecurity founder, engineer and AI researcher who serves as CEO, CTO and founder of Chorology, Inc., a San Jose company applying deep AI to automate data discovery, classification, mapping and compliance enforcement for enterprises. A serial entrepreneur with two prior startups that ended in acquisitions, he previously founded GhangorCloud, a pioneer of fourth-generation data leak prevention, and held senior roles at Symantec, MCI WorldCom and others. He holds dual master's degrees and did PhD research in AI at USC, and holds multiple patents in deep AI.
Willy Halim
Willy Halim is a chemical engineer and the founder of BANIQL, a San Jose climate-tech startup he started in his backyard in 2021 to refine nickel and cobalt without the heat, pressure, and toxic waste of conventional mining. Trained at UC Berkeley and Cornell and seasoned as a battery engineer in Silicon Valley, he built a low-temperature, atmospheric-pressure chemical process that BANIQL says uses about 80% less energy than industry-standard high-pressure acid leaching, produces net-zero toxic waste, and turns leftovers into fertilizer and construction material. The company raised a $1.6M seed round led by BEENEXT in 2024 and added 500 Global and Genesia Ventures in 2025, aiming first at Indonesia, which holds roughly a quarter of the world's nickel.
