Casey Bell
Casey Bell is the co-founder and CEO of Aecore, a technology-enabled commercial general contractor based in San Jose, California. A UC Berkeley graduate and former Turner Construction project manager, Bell took a payments startup called Net30 through Y Combinator's Summer 2017 batch, then pivoted the whole thing into a construction company built with software at its core. Aecore delivers office fit-outs, life sciences facilities, R&D centers, and retail buildouts while running its own proprietary tools for scheduling, photo documentation, and rapid pricing.
Jimmy Jung
Jimmy Jung is the founder and CEO of BuildBlock, a cross-border real estate platform that lets Korean and Asian investors buy, build, and manage U.S. property without ever boarding a plane. A licensed professional engineer who once helped project-manage Google's new Silicon Valley headquarters, he turned the messy, intermediary-clogged process of overseas property investment into a single end-to-end pipeline: search, financing, LLC setup, construction, management, and tax. Founded in 2018 and headquartered in Seoul with U.S. offices, BuildBlock has expanded from residential brokerage into industrial plant and AI-infrastructure development.
Yaser Masoudnia
Yaser Masoudnia is the co-founder and CEO of BlueTape, a fintech company that gives the construction industry's suppliers, contractors and distributors the payment tools and working capital they have long been denied. A serial entrepreneur and a licensed general contractor with over a decade swinging a hammer, he previously built and exited the cybersecurity startup NoPassword (acquired by LogMeIn), then ran the LastPass product team. He started coding games on a Commodore 64 at 13 in Iran and now splits his identity between two worlds most people keep apart: software and construction sites.
Salman Ahmad
Salman Ahmad is the co-founder and CEO of Mosaic, a Phoenix-based, tech-enabled general contractor reinventing how build-to-rent homes get planned and built. He grew up in a construction household, then stacked degrees in computer science from Arizona State, Stanford, and a PhD from MIT before deciding the most interesting unsolved software problem was the most analog industry there is: pouring foundations and framing walls. Mosaic's software platform, Mosaic Hub, coordinates contractors, schedules, and payments so homebuilders can offload construction the way startups offloaded servers to AWS.
Greg Cosko
Greg Cosko is the Executive Chairman (and longtime President & CEO) of Hathaway Dinwiddie Construction Company, one of California's oldest builders. He led the Getty Center build, engineered the 1996 management buyout and merger that formed Hathaway Dinwiddie, and spent nearly three decades steering a 510-person, employee-oriented firm with roughly $300M in annual revenue.
Kevin O'Riordan
Kevin O'Riordan is President and CEO of Hathaway Dinwiddie Construction Company, the 117-year-old, employee-owned San Francisco general contractor behind a generation of California's most photographed buildings. He took the top job on April 1, 2025 after four decades in the trade and five years running the Northern California region. In the same window he was elected 2025 President of the Construction Employers' Association.
Matt Rossie
Matt Rossie is the President and CEO of Webcor, the San Francisco-based general contractor behind some of California's most complicated buildings. He climbed the company over 22 years from the client side of construction into the COO seat, then the corner office, on January 1, 2023.
