Sovereign data pipeline. Automated operations. 80%+ of the seller journey handled before a human touches it.
SA's intelligence layer is built entirely from public government records and commercial valuation APIs. No MLS membership. No brokerage contracts. No data source that can be revoked.
The Maine Real Estate Commission publishes license status, type (Broker, Associate Broker, Sales Agent, Designated Broker), brokerage affiliation, disciplinary history, and license expiration for every active agent in the state. SA maintains a live database of 3,730 agents across Cumberland and York counties, updated from MREC exports.

Town assessor databases (Vision Government Solutions) provide the ground truth: what properties actually sold for, when, and to whom. SA's scraper pulls sale prices, assessed values, ownership chains, deed references, year built, use codes, and property characteristics directly from the Gorham assessor portal. 220 verified sales currently in the database, with full parcel details.

ATTOM Data Solutions provides automated valuation models (AVMs) with confidence scoring for 150M+ U.S. properties. SA's Gorham dataset includes 915 properties with AVMs — average value $568,285, average confidence score 83/100. The AVM gives the seller a market-based estimate independent of what any agent tells them.
Source: ATTOM API. Commercial. Currently on 30-day trial; production access ~$500-2,000/mo depending on volume.
The critical link: which agent handled which sale. V1 uses public MLS listing data (via Redfin sold records) cross-referenced against MREC licenses. SA has verified agent attribution for 30 Gorham transactions with a 79% MREC match rate — enough to compute real, per-agent sale-to-assessed ratios.
V2 path: ATTOM's On Market Listings product (Nexus tier) provides agent name, email, phone, office, MLS ID, listing price, and days on market for active and recently sold properties. This automates Layer 4 entirely and scales to any market. Estimated cost: included in ATTOM production subscription.
V1: Public MLS records + manual verification. V2: ATTOM Nexus (automated, scalable).
Designed for a solo operator at launch, scaling to a small team. Every component is replaceable. No vendor lock-in.

| # | Step | How | Human? |
|---|---|---|---|
| 1 | Seller sees postcard | Personalized direct mail with AVM-derived valuation | No |
| 2a | Seller calls or texts | GHL AI voice agent answers 24/7, qualifies, books consult | No |
| 2b | Seller requests a person | Caller is routed to Carson (V1) or a team member for live scheduling | Yes |
| 3 | Intelligence Report generated | n8n workflow: ATTOM AVM + assessor data + agent scorecard | No |
| 4 | Report delivered | Email + SMS with PDF link | No |
| 5 | Consultation call | Carson walks seller through report, answers questions | Yes |
| 6 | Seller opts into RTA | Digital agreement, one page, terminable anytime | No |
| 7 | Agent matching | Scorecard-ranked agents in seller's area notified | No |
| 8 | Agent pays intro fee | Stripe charge at time of introduction delivery | No |

Three human touchpoints: the live scheduling option (step 2b), the consultation call (step 5), and the warm handoff (step 9). Everything else runs on automation. The AI handles volume; the human option is always available. The handoff stays human by design.
V1 proves the model with sovereign data and manual attribution. V2 automates and scales into a full marketplace platform.
Full agent-to-transaction attribution, automated. Every listing, every agent, every sale — cross-referenced and scored without manual lookup. The scorecard generates itself.
A sponsoring broker provides MLS access, unlocking real-time listing data, days on market, price changes, and expired listings. SA remains unlicensed — the broker provides the data feed, not the license.
The pipeline is market-agnostic. Every state has a real estate commission. Every county has an assessor. ATTOM covers 150M+ properties nationwide. Gorham proves the model. York County is next. Then New Hampshire.
Every Right to Announce engagement captures agent response time, follow-up quality, seller satisfaction, and outcome data. Over 18 months, this proprietary quality index becomes the moat — a dataset no competitor can replicate because no competitor occupies the same position in the transaction.
As the behavioral dataset grows, SA ratings become something agents actively want. Top performers display their SA score the way contractors display Yelp stars or Google LSA badges. The scorecard stops being something agents tolerate and becomes something they compete for — driving better service to sellers, which drives better data, which drives better rankings. The platform becomes self-reinforcing.
This isn't theoretical. Angi (formerly HomeAdvisor) has operated this exact marketplace structure for 26 years — non-contingent fees from an unlicensed platform connecting homeowners to service providers. All 50 states. $1.19B revenue. The FTC investigated and never challenged the core model. SA applies the same architecture to the one home services category Angi doesn't touch.
