ConstructionYardSale is the only verified P2P marketplace for used and surplus construction materials and equipment. The US construction industry generates roughly 600 million tons of construction and demolition waste every year, more than twice all municipal solid waste. Nearly 145 million tons goes straight to landfill. It's estimated that nearly a third of that is reusable. Contractors over-order on every job, and what's left over gets thrown away, not for lack of a buyer, but for lack of a trusted place to sell it. Craigslist and Facebook Marketplace are anonymous, cash-based, and weren't built for trades - No identity verification, no payment protection, no recourse when materials don't match the listing.

ConstructionYardSale solves that. It's a verified, construction-only marketplace where every user completes Stripe identity verification, payment is held until a release code is exchanged at pickup, and both sides rate each other after every transaction. It's the first platform built specifically for this category, with no dominant national competitor.

A Turnkey, Fully Built Platform

This is a complete, professionally engineered SaaS marketplace that has already launched - not a concept or MVP:

Sharetribe marketplace engine with a custom Node.js backend running ~60 API endpoints
Supabase database with edge functions for pickup codes, boost scheduling, AI moderation, and reviews
Live Stripe Connect: identity verification, delayed-capture payments, subscription billing, ACH
Approved Twilio SMS campaign, transactional email, helpdesk, monitoring, and analytics
Delaware C-Corp with attorney-drafted Terms of Service, Privacy Policy, and dispute policy
A premium exact-match domain and complete brand system

Replacing this would cost an estimated $78,000–$135,000 and take 6–9 months. A buyer starts from a live, working business, not a blueprint.

Software Economics - Built to Be Profitable Fast

No inventory, no lease, no payroll, no logistics. Every transaction is local pickup, and the seller - never the platform - holds the goods. The fully-loaded tech stack costs approximately $800/month, or about $9,600/year.

Any one of the following covers that entire monthly cost on its own:

64 sales/month at a $200 average sale (about 3 per business day)
17 sellers on the $49/month Pro tier
6 businesses on the $149/month Business tier
176 paid listing boosts at $5 each

These stack in practice, meaning roughly 25-30 active sellers makes this business profitable. Past that point, the same platform serves 1,000 sellers at no meaningful added cost - nearly every additional dollar drops to the bottom line.

A Real Environmental and Economic Tailwind

Connecticut lost roughly a third of its in-state disposal capacity when the Hartford trash-to-energy plant closed in 2022, and now ships close to 40% of its waste out of state - a problem the state is actively funding diversion programs to solve. Every completed sale here diverts material from a landfill, recovers cash for a seller, and gives a buyer a bargain. That impact opens doors a plain resale site can't reach: municipal partnerships, sustainability grants, and green-building suppliers.

Why It's For Sale

The founder accepted cannot give this business the daily attention a young marketplace needs. The sale is about availability, not about anything discovered regarding the platform or the market.

What's Included

All source code and documentation, live Stripe and banking infrastructure, the Delaware C-Corp and legal documents, the branded domain and marketing assets, and full transition support - training, vendor handoffs, and introductions to the developer and legal counsel. Asset or stock sale structures are open, and seller financing will be considered for a qualified buyer.

A rare opportunity to acquire a fully engineered marketplace platform in a massive, underserved category, for a fraction of the replacement costs to build.
