Velum Labs
Velum Labs is a Y Combinator-backed San Francisco startup building an operating system for data quality. Its platform continuously watches a company's data stack, catches when metrics and definitions diverge, traces the root cause through query lineage, proposes automated fixes, and then writes enforceable data contracts so the same break does not recur. Founded in 2025 by Chilean-born childhood friends Benjamin Munoz-Cerro (CEO) and Alen Rubilar-Munoz (CTO), the company is already in production at regulated fintechs monitoring 200+ tables tied to more than $1B in assets.
Vinay Goel
Vinay Goel is the CEO and co-founder of Wald.ai, a Palo Alto startup building contextual data-loss protection for the age of generative AI. After more than 30 years in product and technology - a decade at Google leading Maps and Local, then top product roles at JLL, Kiavi, Check Point and Webroot - he co-founded Wald.ai in 2024 to solve the 'shadow AI' problem: employees feeding sensitive company data into ChatGPT, Claude and Gemini. Wald.ai redacts sensitive data inline, lets the AI answer, then restores the original context before the user sees it. He raised a $4M seed round in December 2024 and sits on the Forbes Technology Council.
Luke Arrigoni
Luke Arrigoni is the founder and CEO of Loti, a Seattle startup that hunts the internet for deepfakes, impersonators, and unauthorized images of its users and gets them taken down - usually within 17 hours. A mathematics graduate turned data scientist, he spent over a decade running the AI consultancy Arricor for clients like Getty Images and AT&T before co-founding Loti in 2022 with his wife Rebekah Arrigoni. The company scans roughly 100 million images and videos a day, has captured a large share of the A-list celebrity market, raised a $16.2M Series A led by Khosla Ventures, and now offers free likeness protection to everyday people.
Alon Webman
Alon Webman is the co-founder and CEO of Chain Reaction, an Israeli semiconductor company building purpose-built chips for encrypted computation, Bitcoin mining, and privacy-preserving AI. Before Chain Reaction, he co-founded Mellanox Technologies in 1999 and spent nearly two decades there, rising to VP-level roles before NVIDIA acquired Mellanox for $7 billion in 2020. A Technion graduate, Webman is now betting his second act on making fully homomorphic encryption practical at scale - a technology that would let clouds compute on data they can never see.
