Stewart Global Ventures

A founder who builds from the ground up.

Robert Stewart, Founder & Principal

Robert Stewart is the founder and principal of Stewart Legacy Holdings. Born in Brooklyn and raised in Weston, Florida — just west of Fort Lauderdale — he started building businesses before he finished school. While earning his Associate degree in Marketing from Broward College, he launched his first company: a publishing, web and app design, and multimedia production studio that he ran through his early twenties.

The pull toward operations came next. He relocated to Sacramento to immerse himself in the region's rapidly growing specialty agriculture market, with the goal of learning the business from the ground up — controlled environment cultivation, advanced plant genetics, and the regulatory compliance that high-value crops demand. Over seven years he combined precision cultivation with strategic supply chain management to drive yield optimization and operational growth, building the operational discipline that anchors everything he does today.

He then relocated to Hollywood, California, and turned that operating foundation into a portfolio. Today, through Stewart Global Ventures, Robert builds and owns companies across global sourcing, brand and product development, technology and digital assets, media, and agriculture — bringing more than 15 years of cross-industry experience and a decade in digital currency to each one.

His approach is consistent across every field: understand the supply chain, control the quality, build the brand, and own the outcome.

Legacy & Family

Stewart Legacy Holdings is named for what it's meant to become: an enterprise that outlasts its founder. Robert builds alongside his wife and business partner, Sophia Mascioni, for the next generation he's building for. The word legacy in the company's name is not branding. It's the mandate.

Leadership Philosophy

Own, don't advise.

We put capital and operating muscle into every venture. We win when our partners win.

Control the chain.

Quality is decided at the source. We build from the supplier up, never the marketing down.

Think in decades.

We measure success in durability, not quarters.
