6SILO
We Build Brands with Soul, Scale & Systems.
6SILO is the venture portfolio and future family office of Don Hett — building purpose-led brands across Commercial Services, MarTech, Sustainability, and Wellness. We don't just build companies. We build movements that give back.
Why We Exist
From a garage in 2012 to a global venture ecosystem: 6SILO began with one belief: purpose and profit can co-exist.
Founded by Don Hett, 6SILO was built on the lessons of real entrepreneurship:
- •Growing CleanKings from zero to 650+ jobs
- •Turning ideas like Crittiks and Earthy Tabs into scalable impact models
- •Proving that when business serves communities, growth follows naturally
We're not here to chase hype. We're here to build companies that make the world run better — and do it profitably.
