Mandelbrot.ai — an AI-native land bank
The pricing system for urban infill land.
Purpose-built to find turning neighborhoods, underwrite every lot against real builder plans, and clear buy boxes with the one number that matters — the max land bid.
One engine, two doors. Owners start the conversation; builders take down the lots.
For sellers
See what a builder would pay for your lot
Enter your address. If your neighborhood is in coverage, a named builder's value indication is already computed — no sign-up, no cold calls, no obligation.
Check your lot estimateFor builders
A land pipeline shaped to your buy box
Keep your buy box, plan library, and spec docs current in the portal; review the site condition and underwriting on every lot we bank for you — then take it down.
Open the builder portalA new species of land company. Residential land is the largest asset class in the country, and nobody owns it at scale — it is still priced by feel.
FIG 0.1
Fast-following
Enter when the first comps print in a turning neighborhood — before the land premium is baked in, not after.
FIG 0.2
Builder economics
Generic AVMs miss by dollars per foot, and infill margins die by dollars per foot. Every lot is priced through real plan libraries.
FIG 0.3
Asset-light
Options and assignment contracts control the upside without the carry, so capital compounds instead of parking.
1.0 Screen
Find the neighborhood before the premium
Market signals read permit velocity, new-build comps, teardown concentration, and school trajectories nightly — so the next turning block is on the map before its comps print.
2.0 Underwrite
Price every lot the way a builder would
The engine runs each parcel through real plan libraries — width, depth, cost per foot, finish tier — and solves the builder's own economics down to a single defensible bid.
3.0 Clear
Send builders only what clears their buy box
Ranked deal feeds match underwritten lots to each builder's order book, replacing the 3% sourcing fee with a price they can sign.
