What Stack does

Real-time intent signal

Tenants tell you whether they plan to stay or might leave — months before lease expiry. It's a live signal, not a survey.

Self-serve renewals

One tap extends the lease and escalates rent. No emails, no chasing, no DocuSign. Zero leasing agent labor per renewal.

Retention without concessions

Tenants stay because leaving means forfeiting a growing balance. Rent goes up every renewal. The bonus compounds — so honesty is the highest-paying strategy.

Straight to NOI

A 300-unit building losing 150 tenants/year spends $750K/year in turnover. Stack prevents those move-outs at a fraction of the cost — 5× return, 5–22% building appreciation.
