Lettie
Lettie is an AI-powered platform that lets letting agents manage tenant maintenance over WhatsApp.

Overview
Lettie helps letting agents manage tenant maintenance over WhatsApp, using AI to triage issues, verify tenants, and automatically sync requests into Street.co.uk.
Key Features
- WhatsApp maintenance requests, synced to Street.co.uk.
When a tenant reports an issue via WhatsApp, Lettie handles the conversation first. If the issue can’t be resolved automatically, a pre-populated maintenance request is created in Street and linked to the correct property and tenancy, no manual input required. - AI-powered issue triage and diagnosis.
Lettie’s AI analyses WhatsApp conversations to diagnose the problem, assess urgency, and provide fault context before the request ever reaches your team. That means maintenance jobs arrive in Street pre-qualified, prioritised, and ready to action. - Daily tenancy and branch sync.
Active tenancies and branch data are pulled from Street daily (or on demand), with Street remaining the single source of truth. This ensures every conversation and request is always tied to the right tenant and property.
Key Benefits
- Save hours on maintenance admin.
No more copying messages, chasing details, or re-keying data. Maintenance requests flow straight from Lettie into Street, freeing your team from repetitive admin and letting them focus on resolution. - Reduce errors and protect data accuracy.
Every request is automatically matched to the correct tenancy and property in Street, eliminating mismatches, missed context, and costly mistakes. - Built-in compliance and audit trails.
All tenant interactions are verified and date-stamped from the very first message. Full conversation history and context are stored alongside the maintenance request in Street, helping you stay compliant without extra effort.
