The People Behind the Machine
Behind every system we build is a team that believes in purpose over ego, collaboration over chaos, and impact over noise.
The Vision Behind It All
Don Hett is a founder, investor, and builder of systems. From turning a small cleaning startup into an 8-figure business with over 650 staff, to launching purpose-led brands across sustainability, tech, and wellness. Don's journey represents what 6SILO stands for: soul, scale, and structure. He built 6SILO as a venture ecosystem and future family office, creating companies that not only grow fast, but grow right.
"I don't build to exit. I build to leave something behind."
