Jon Sibley
Jon Sibley is the Founder and CEO of TrueBuilt Software, an AI-native preconstruction platform headquartered in Huntington Beach, California. A former NCAA Division I water polo player at UC Berkeley and Team USA competitor, Sibley translated elite-sport discipline into enterprise software sales at Quid and Visa before founding TrueBuilt in July 2022. The company raised a $4 million seed round in 2023 led by Bienville Capital with participation from Fifth Wall, and in late 2025 acquired Capabuild — a mobile field documentation platform — driving a 124% revenue increase in three months post-close. TrueBuilt consolidates what was once a fragmented 6-8 tool preconstruction workflow into a single AI-powered platform serving general contractors and subcontractors.
Zack Eakin
Zack Eakin is the co-founder and CEO of Layup Parts, a Huntington Beach startup that wants to make ordering custom carbon-fiber and fiberglass parts as easy as ordering from Amazon. A composites engineer who started in IndyCar bodywork at Chip Ganassi Racing, became the first engineer at Elon Musk's The Boring Company, and led mechanical engineering on Anduril's Roadrunner drone, Eakin launched Layup in 2024 to attack a problem he kept hitting himself: composite parts that take weeks and cost a fortune. With software-driven manufacturing and standardized stock materials, Layup compresses some jobs from weeks to hours. In June 2026 the company raised a $42 million Series A led by Marlinspike, on top of a $9 million seed from Founders Fund.
