The construction worker's son who learned to build spacecraft is about to disrupt a $1.4 trillion industry that hasn't changed in 70 years. Nick Callegari spent his childhood summers working construction sites alongside his father, a laborer who still builds walls in Florida using the exact same methods he used 30 years ago. Then Nick went to work as an engineer at SpaceX, where he watched a team challenge every assumption about what's possible and accomplish the extraordinary. That contrast haunted him. 41% of America's construction workforce retires by 2031. We're already millions of homes short. And Nick's own family experienced the crushing pain of housing insecurity, so he understands the problem that faces millions of American families. So he left SpaceX and rockets behind to solve it. In this deeply personal episode of The Optimistic Outlook, Forbes 30 Under 30 founder Nick Callegari reveals how his company Verustruct are using mobile robotics and AI-powered 3D printing to build affordable homes at a scale traditional construction never could, and why this matters to investors, manufacturers, and anyone who believes advanced technology should serve basic human needs first. Host Peng-Sang Cau— a Cambodian refugee, former founder, and now Siemens' startup ecosystem leader — brings her own story of survival and technology's promise to this conversation about who gets access to the future we're building. You'll discover: Why the housing shortage is a skilled labor crisis that automation must solve How the Verustruct mobile 3D printing system works differently and with greater agility than any other 3D printing technology for homes  What $2.1M in pre-seed funding means for construction's digital transformation Why "the future is here, but not evenly distributed" — and what Siemens is doing about it The personal pain that drives mission-focused founders to tackle society's thorniest problems How Siemens for Startups partners with innovators from concept to automation at scale This isn't another startup story. It's about how we're finally applying spacecraft-level innovation to the fundamental right of shelter. For leaders in construction tech, real estate development, automation, venture capital, or manufacturing: this is the conversation about where digital transformation meets demographic crisis.
