About
Built from the work. Structured for scale.
6SILO is the venture portfolio and future family office of Don Hett: a practical operating group built around proof, systems, patient capital, and measurable impact.

Melbourne founder, operator, and builder of the first 6SILO venture.
The Origin
Not a pitch-deck-first business.
Don still looks at operating metrics with the same attention he brought to CleanKings in the early days. The portfolio is the result of repeating that discipline across software, sustainability, wellness, commerce, and payments.

“If I can't still explain why this business should exist in twenty years, we shouldn't build it now.”

Operating Philosophy
A venture earns attention only after the fundamentals are real.
01
Demand before brand.
02
Systems before scale.
03
Ownership before exposure.
04
Numbers before opinion.
Our Framework
The Six Pillars of 6SILO.
The same operating checks show up before a venture gets brand, capital, or public attention.
01
Idea & Insight
Validation Before Execution
We only build for real, validated problems. Every venture starts with deep market research and genuine need. No vanity projects. We validate demand before we build, using customer discovery, competitive analysis, and market sizing to ensure every venture solves a meaningful problem.
02
Technology
Built to Scale
Scalable, automated, intelligent products and systems. We leverage cutting-edge tech to create competitive advantages. Modern tech stacks, cloud infrastructure, AI integration, and automation-first thinking. We build platforms that scale globally without breaking.
03
Marketing & Storytelling
Brands That Resonate
Emotion-first narratives that move communities. We build brands that resonate and inspire action. Content-led growth, organic community building, and authentic brand positioning. We don't just sell products — we tell stories that people want to be part of.
04
Investment & Capital
Long-Term Value Creation
Built to compound, not chase short-term gains. Strategic capital allocation for sustainable growth. Patient capital, strategic reinvestment, and disciplined financial modeling. We invest in ventures designed to generate long-term returns and build generational wealth.
05
Legal & IP
Protection From Day One
Protecting every venture from the start. Comprehensive legal frameworks and intellectual property strategy. Trademark protection, contracts that scale, regulatory compliance, and IP ownership. Every venture is legally sound from day one.
06
Finance & Control
Data-Driven Decisions
Financial integrity and clarity in everything we do. Transparent systems that drive accountability. Real-time dashboards, unit economics tracking, and financial discipline at every level. We know our numbers and we make decisions based on data, not guesses.
Get Involved
Three ways into the room.
Investors
Capital that understands operations.
For family offices and private investors who want exposure to practical ventures with clear operators, legal foundations, and weekly numbers.
Collaborators
Skill that earns ownership.
For engineers, brand builders, finance operators, manufacturers, and legal specialists who want to build equity, not just invoice hours.
Following
Watch before you commit.
For people tracking how a multi-venture group is actually built, sector by sector, from the operator's desk.
