Challenge

Multifamily Demand-Handling Voice Agent using CrewAI and VAPI Integration

Multifamily operators struggle with lead conversion due to slow response times and inefficient inquiry handling. Build a multi-agent CrewAI orchestration with VAPI voice interface integration that handles prospective tenant inquiries and schedules property tours with under 2-second response latency.

Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Design a collaborative CrewAI agent ensemble paired with VAPI real-time voice streaming to capture prospect preferences, check lease management DBs, and book automated tours.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
3 scoring checks
Binary
3 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

Qualification Evaluation

Checks if qualification decision matches financial parameters.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

Tour Booking State

Verifies that tour booking succeeded without errors.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 3

intent_extraction_accuracy

Accuracy of unit target and timestamp extraction from call transcript • target: 1 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Configure CrewAI agents with dedicated roles for lead intake, lease database lookup, and tour scheduling.

  • Integrate VAPI Webhooks to stream audio transcriptions to the agent ensemble in real time.

  • Enforce tenant pre-qualification parameters (income-to-rent ratio, move-in timeline).

  • Achieve zero booking conflicts across automated scheduling calendar endpoints.
