Case study Built by Decent4 for a CRE brokerage

A workflow platform for commercial real estate brokers.

A B2B workflow platform Kyle designed and shipped end-to-end — front end, API, auth, data model.

LeaseLineage handles prospect outreach, campaign management, and tenant pipelines in one place. Designed for how CRE actually runs — not bolted onto a generic CRM. If you have a B2B workflow problem in an industry that generic tools don't fit, this is the kind of build Decent4 ships.

What LeaseLineage handles

Prospect outreach

Targeted lists, multi-touch sequences, and follow-ups that don't get dropped when the week gets busy.

Campaign management

Run leasing and tenant-rep campaigns with clear owners, current status, and full history in one place.

Tenant workflows

Move tenants through the stages CRE actually uses — tour, LOI, negotiation, close.

Pipeline visibility

One view of who's working what, where it stalled, and what's next.

Why this exists

Commercial real estate is one of the last industries running on spreadsheets and email threads. Brokers are paid to broker deals, not to wrestle with a CRM designed for a SaaS sales team selling seats.

The generic tools all have the same problem: they model a deal as a single contact moving down a single pipeline. CRE doesn't work like that. A single tenant rep engagement can touch dozens of landlords, multiple submarkets, and span quarters. Outreach campaigns target buildings, not people. Status changes mean different things in leasing than they do in capital markets.

LeaseLineage is built around how CRE actually works. The data model, the screens, and the daily workflows all match how a broker moves through a week — which is why the team actually uses it.

Generic stack vs purpose-built

What you get with a Generic CRM + spreadsheets + email

  • Pipelines modeled on B2B SaaS sales, not CRE deal flow
  • Prospect lists live in someone's laptop
  • Campaign status is "ask the broker"
  • Tenant workflows don't map to LOI, tour, negotiation
  • Reporting means rebuilding a spreadsheet every time

What you get with LeaseLineage

  • Built around buildings, tenants, and reps — not generic contacts
  • Prospect lists are shared, queryable, and current
  • Campaigns have owners, stages, and a real history
  • Tenant pipeline reflects actual CRE stages
  • Pipeline visibility is a live screen anyone on the team can open

What shipping it proved

LeaseLineage is client work, not a Decent4-owned product. It's on this site because it answers a different question than the consumer apps: can Decent4 walk into an industry it didn't grow up in, learn the domain, and ship a working B2B platform end-to-end — front end, API, auth, data model, and all the messy parts in between.

Most B2B workflow software fails because the team building it doesn't sit close enough to the work. Building LeaseLineage meant learning how brokers actually run their week and designing the data and screens around that — not bolting custom fields onto a generic tool and calling it done.
