Mantle v0.3 · book + plan · 2026

Mantle.

The transaction workspace for top-producing real estate agents. Mantle owns the stretch between accepted offer and closing, the highest-stakes and least-tooled part of a deal: deadline and document tracking, closing-readiness, and client communication drafted in the agent's own voice.

The canonical volume · 2026

Mantle - the book.

The deal-room thesis end to end - the wedge, the three compliances, the GTM, the competitive landscape, and the seven research tracks that prove or kill it. The canonical volume for the project.

Operating plan · internal

The plan, gated.

The execution counterpart to the book: four validation-gated phases, the R1-R7 research backbone, the build order, the land-and-expand motion, and the next 90 days. Model-shape, no invented numbers.

Working pages

  1. 01 Plain terms The Product What Mantle is, part by part: tracking, closing-readiness, and communication in the agent's voice. The boundaries, the document layer, and how it runs across a working day. →
  2. 02 The surface Dealroom design Feature design for the transaction surface: deal dashboard, single-deal timeline, voice-profiled seller updates, compliance pre-flight, and the broker file. Five screens. →
  3. 03 Reference Document matrix Every document in a transaction scored on access, exploitability, and breach risk: the map of where Mantle must be careful, and where the agent's inbox is the weak link. 23 documents, NY/CT. →
  4. 04 Competitive read The landscape Ten players across four rings, rated on the four capabilities that matter. Where Mantle wins today, where it is exposed, who is closest to closing the wedge, and the six-point readiness test. →
  5. 05 Build sequence The roadmap The five-layer build order as Now, Next, and Later - gate-faithful, no calendar commitments. Pre-gate spikes, the wedge MVP epics with hypotheses and success metrics, and the layers that are earned, not scheduled. →
  6. 06 Gated · confidential The data room Passphrase-gated. State of play, honest; every document in the room; who is running this; and what is useful now. If you don't have the passphrase, it isn't meant for you yet. →
