LUMBY · The construction materials marketplace

About Lumby

Lumby is rebuilding how contractors source construction materials with transparent quotes, direct communication, and a single source of truth from RFQ to delivery.

Contractors and suppliers both deserve a single source of truth.

Every RFQ, quote, message, and delivery in one place. Nothing gets lost in email, and nothing is re-asked over the phone.

Every conversation belongs with the project.

RFQs, quotes, messages, and updates all stay attached to the job. No more digging through email chains or wondering what was promised.

Suppliers deserve to get paid fast.

No chasing invoices. Payment flows directly through Stripe to the supplier's account.

How it works

Contractors create their material list, or upload plans for an AI-assisted material takeoff, and choose exactly which suppliers to send the request for quote to. Suppliers respond with line-item pricing. Contractors compare, award in one click, pay by card or bank account (right away, or on COD or Net terms when the supplier offers them), and track the delivery from yard to job site, all inside Lumby.
