## The Problem

Tenant renewals in Office & Industrial Leasing portfolios approach without the landlord team noticing — and a non-renewing tenant is 18 months of lost NOI and leasing cost.

## What We Build in CoStar

AI tracks renewals in CoStar, drafts a renewal proposal with market comps, schedules the tenant call, and escalates any non-response — renewal rate climbs and vacancy drops. Purpose-built for teams running CoStar — uses the native API or agent integration so nothing leaves the system of record.

## CoStar Integration Approach

1. **Audit your CoStar configuration.** We map the specific CoStar objects, custom fields, and workflows the automation needs to touch for your office & industrial leasing practice.
2. **Build on the CoStar API or agent.** Integration happens inside CoStar — no data leaves the system, no parallel tool for your team to learn, no license changes.
3. **Human-in-the-loop handoff.** Every automation routes exceptions back to a human in CoStar with full context — AI handles the 80%, your team owns the judgment calls.
