Vertical: residential real estate — don't spec it naively

Real estate looks like generic CRUD (a listing is a record, a lead is a contact, a deal is a checklist). It isn't. The domain has hard-won structure — MLS quirks, status lifecycles, months-long sales cycles, agent-vs-brokerage data boundaries — that a naive build ignores and then rebuilds. This skill front-loads that structure so the spec is right the first time.

Incumbents to know (and what they own): Lone Wolf / Propertybase (brokerage CRM + back office), Follow Up Boss (lead-to-close CRM, the nurture gold standard), CINC (lead-gen

• CRM), Top Producer (legacy CRM), kvCORE / BoldTrail (all-in-one platform). They are expensive, broad, and switching-cost-heavy — which is why the wedge matters (see per-product).
