Good ideas for your block die
because no one wants to go first.
Quorum.ai fixes that.
A threshold pledge engine for local collective action. Set a minimum. Let neighbors commit conditionally. The AI Organizer handles the rest.
Group Solar Buy
12 needed · Dec 15
The first-mover problem
Great neighborhood ideas die in silence. Someone posts about group solar, three people express interest, then… nothing. Nobody wants to commit time or money until they know enough others will too. It's a coordination failure, not a lack of interest.
The Idea
"What if we all got solar together?"
The Silence
Three people liked it. Nothing happened.
With Quorum.ai
Threshold hit. Organizer activated. Deal done.
How it works
Three steps from idea to action — with AI handling the coordination labor.
Propose with a threshold
Set a minimum number of participants and a deadline. "I'm starting this if 10 neighbors join by Dec 15."
Neighbors pledge conditionally
"I'm in — if enough others are." Nobody goes first alone. Everyone commits together.
Quorum.ai hits → AI takes over
The AI Organizer drafts outreach, researches vendors, splits costs fairly, and generates a plain-language agreement.
Real neighborhood use cases
From bulk buying to co-ownership to tenant organizing — if it needs a quorum, Quorum.ai can help.
Group Solar Buy
Split installer costs 12-ways and unlock bulk pricing neighbors can't access alone.
Block Snow Removal
Share a seasonal contract with a local service — everyone gets plowed, nobody overpays.
Co-owned Cargo Bike
Pool resources to buy a cargo e-bike the whole block can borrow.
Renters Association
Get enough renters together to form a recognized association with real bargaining power.
School Carpool
Match families with kids at the same school into a rotating drop-off schedule.
Heating Oil Group Buy
Order together in bulk at the start of the season when prices are lowest.
✨ The AI Organizer
Once you create a campaign, the AI Organizer handles the coordination labor that historically killed good neighborhood ideas.
Draft Outreach
A warm, honest message to share with neighbors — tailored to your campaign type.
“"Hey neighbors! I'm organizing a group solar buy for our block. We need 12 households to get the bulk rate. No obligation unless we hit the number — want in?"”
Vendor Research
2–3 plausible vendor options with rough price ranges and what to ask them — clearly labeled as estimates.
“SunPower: Residential installer, ~$2,800/panel. Offers group discounts. Ask about: warranty, permitting timeline.”
Fair Cost Split
Per-household or per-person breakdown based on committed count and your cost model.
“At 12 households: $2,083/household. Currently (9 pledged): $2,778/household.”
Participation Agreement
A plain-language, non-legal summary of who commits to what and under what conditions.
“This is a conditional commitment. Nothing is binding unless 12 households commit by Dec 15. If quorum isn't reached, no one owes anything.”
