You need persistent memory across Call, WhatsApp, SMS, and in-app.

You want voice AI built by a team that owns your business metrics.
Acceptable voice quality, but conversations feel mechanical under stress.

For voice AI on outbound consumer sales in India, yes. For contact center QA, agent coaching, and conversation analytics on a human agent operation, particularly in the US market, Convin's platform is built for that specific job. The honest question is which job you're hiring the platform to do, and which market you're hiring it for. Convin makes your contact center better. SquadStack makes the contact center optional, with voice AI that runs every call at human-level quality.
Both companies offer voice AI agents. The architectural difference shows up in three places. First, training data: SquadStack is trained on 600 million minutes of real Indian outbound sales calls, Convin trains on 10K+ live calls weekly across its broader contact center base. Second, voice stack: SquadStack runs proprietary models end-to-end, Convin uses ElevenLabs for TTS as publicly confirmed, with STT not disclosed. Third, target use case: SquadStack handles 30+ turn complex sales calls, Convin's AI Phone Calls are positioned for transactional interactions like payment reminders and appointment confirmations.
Common pattern. Several Indian enterprises run conversation intelligence platforms for analytics on their human agent operations and SquadStack for outbound voice AI agents that augment or replace human callers on high-volume sales campaigns. The two products solve different problems and don't conflict. Convin watches and improves your human agents. SquadStack runs the calls without them, at 3x lower CAC than human teams.
The POC runs against your actual sales KPIs: connectivity, qualified leads, conversion rate, CAC. SquadStack runs on your real campaign data and your current baseline. POC success rate has been 93% against an industry average of 25%, on outbound voice campaigns where conversion is the contracted KPI.
