Sentinel

The operating system for multifamily marketing and acquisitions.

What it is

Sentinel is the software a multifamily operator runs the day on — pricing intelligence, leasing CRM, campaigns, reputation and acquisitions underwriting in one place, instead of five tools that do not talk to each other.

The problem it was built for

Multifamily marketing teams were stitching together a CRM, a pricing spreadsheet, an email tool, a review dashboard and an underwriting model — then re-keying the same numbers between them. Nobody could answer "what should this unit rent for, and why" without a meeting.

What Zorm built

  • Pricing intelligence that reads the market — HUD, Census, BLS and rent indices resolved down to the county, turned into a plain-language read a leasing agent can act on.
  • A leasing CRM with lead attribution, automated nurture and the reporting layer above it.
  • Campaign tooling and a reputation surface that keeps every community consistent.
  • An acquisitions module with a pure-PHP finance engine and versioned, lockable underwritings.
Zorm's roleBrand, product design, full-stack engineering, and the ongoing operation — Zorm still runs it.

Why it counts as proof

Sentinel runs a real portfolio every day, not a demo dataset. This is not a case study — Sentinel is a Zorm product, still operated by the team that built it. The same practice is available for client work.
