What Sierra actually does well
Sierra has the strongest IDX website product in the segment and a proven Smart Targeting reactivation engine. The CRM half is good. The AI half (when bolted on) is significantly slower than purpose-built voice AI.
3 reasons real estate agents pick Streamsynq instead.
- You want voice AI that responds in under 60 seconds — Sierra's reactivation cadence measures in days, not minutes.
- You're tired of paying for Smart Targeting as an extra add-on on top of the base CRM.
- You want to keep Sierra as your CRM AND add Streamsynq as the AI ISA — they coexist via webhook.
