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.

Don Hett
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
Problem First
Prove It Before You Build It
Nothing gets built here because it's fashionable. Before a line of code or a supplier contract exists, we run customer interviews, size the market, and check who else has tried and failed.
02
Engineering
Built So It Doesn't Break
Every product runs on infrastructure chosen for what it costs to maintain in year three, not how fast it was to ship in week one — cloud-native by default, automation wherever repetition creeps in.
03
Brand & Voice
Say Less, Mean More
A venture's story has to survive contact with a skeptical customer, not just a pitch deck. We build positioning around what a brand actually does for the person buying it.
04
Capital Discipline
Patient Money, Not Fast Money
6SILO ventures aren't optimized for a quick flip. Capital gets deployed in stages tied to proof points, reinvested rather than extracted early, modeled against a decade horizon.
05
Legal Foundations
Boring on Purpose
Trademarks filed, contracts reviewed, and ownership structures settled before a venture takes its first paying customer — not after a dispute forces the issue.
06
Numbers, Weekly
If We Can't Measure It, We Don't Trust It
Each venture reports unit economics on a set cadence, not whenever someone remembers to check. Decisions get made off that data, not gut feel or the loudest voice in the room.
Get involved
Three ways into the room.
01
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.
02
Collaborators
Skill that earns ownership.
For engineers, brand builders, finance operators, manufacturers, and legal specialists who want to build equity, not just invoice hours.
03
Following
Watch before you commit.
For people tracking how a multi-venture group is actually built, sector by sector, from the operator's desk.
