66%
of sellers found their real estate agent through a referral
Real estate is already a referral market. Sphere of Six digitizes the asset that already exists.
A GROWTH PROPOSAL · JUNE 2026
You've launched the trust layer. Now let's build the demand.
Sphere of Six has the rarest asset in marketplace startups: an authentic trust mechanism, validated providers, and a founder who is the ICP. What's missing is a system to acquire the demand side.
THE THESIS
Trust is the moat. Marketing should be designed around it — not in spite of it.
Most home services marketplaces compete on price-per-lead. Sphere of Six competes on something the market actually wants but no platform delivers: a recommendation from someone you know.
Per Nielsen's global trust study, 88% of consumers trust recommendations from people they know more than any other form of marketing — across 56 countries and 40,000 respondents (Nielsen, 2021). McKinsey estimates word-of-mouth drives 20–50% of all purchasing decisions (via Buyapowa).
This is what Sphere of Six already does. The product is right. What I'd build is the system to make that trust scale — without breaking the thing that makes it trustworthy in the first place.
THE OPPORTUNITY
Three numbers worth knowing
$520B
US homeowner improvement and repair (2026)
Most of this spending still flows through offline, trust-based channels — the exact territory Sphere of Six occupies.
$1,400+
what contractors pay Angi for each closed customer (est. 2024)
Incumbents bleed margin paying for leads. A referral-driven model removes that tax — and that gap is where Sphere of Six's unit economics live.
