Our Story
Born from Vision. Built on Trust. Driven by Purpose.
Vault was created by two industry leaders who believed that the remodeling and design experience could—and should—be better.
On one side, Maor Greenberg, the founder of Greenberg Design Gallery in Palo Alto, had spent years refining the high-end design showroom experience, curating elevated materials and delivering personalized guidance to homeowners and professionals across the Bay Area.
On the other, Theo Doussineau, founder of RD Homes in Santa Barbara, had built a thriving remodeling and construction brand grounded in a deep commitment to client care, efficient execution, and complete material sourcing for beautiful, functional spaces.
As their paths crossed, so did their visions.
What began as mutual admiration quickly became a shared mission:
To take the best of what each had built—personalized service, curated products, streamlined systems, and true accountability—and combine them into something more powerful.
Vault was born.
Theo's Mission: Redefining the Marketplace
For Theo Doussineau, Vault is more than a business—it’s a calling.
After years of seeing homeowners struggle with scattered advice, overpriced materials, and hidden markups, his mission became clear:
To transform how materials are sourced in this industry.
Vault exists to build a transparent and fair marketplace—where guidance is accessible, information is shared freely, and costly mistakes are avoided before they happen.
It’s about leveling the playing field, so every homeowner, designer, and builder can make informed choices, not just expensive ones.
