ML Systems guides homeowners through a different way to rebuild: Loan Origination → Deconstruction → Construction — one connected journey, tracked in one place. LOAD YOUR HOME Enter your address and basics, and the app builds your home's model — the numbers every part of the platform works from. YOUR EQUITY, EVERY CYCLE Follow the value chain loop: financing funds the work, deconstruction recovers your home's materials, and construction rebuilds bigger. The equity dashboard shows your property value and progress through each cycle. AN AI COLLECTIVE ON YOUR SIDE Ask anything about your home in one conversation. A team of specialized AI minds — finance, deconstruction, design, construction — works your home's real numbers and answers plainly, with the cost of every answer shown. RECOVERED MATERIALS MARKETPLACE Browse Builder's Open House: reclaimed lumber, brick, fixtures, and whole-house bundles recovered through deconstruction — graded, priced, and local. DECON LAB Point your camera at a site or material and get an instant read on what's recoverable — the R&D turning salvage into new building products. NEIGHBORS Rooms where homeowners going through the loop stay connected — swap tips, ask questions, and show your rebuild. Sign in with Apple or Google. Your session stays on your device. ML Systems is a construction and technology company in Rhode Island. It presents loan and equity information for planning purposes and is not a lender; financing runs through participating capital partners. Equity figures shown in examples are modeled projections, not guarantees.
