Built for ticket deflection, FAQ resolution, and inbound query handling.
Holds 30+ turns of objection handling without losing the thread or repeating itself.

Optimized for resolution and containment metrics, not conversion or persuasion.
Reads the lead's CRM history in the first second, opens calibrated to who they are.
Generic enterprise voice library, not trained on the energy of a sales pitch.

You're driving sales conversion at scale for India's consumer brands.
You need voice AI trained on real Indian sales conversations across Hinglish, Tanglish, and regional code-mixing.
Your KPIs are conversion lift, CAC reduction, and connectivity.
You need an agent that holds long calls, remembers leads, and works across channels.
You want a forward-deployed team of engineers owning your business metrics.
You're automating customer service across voice, chat, and email for a global enterprise.
Your KPIs are ticket deflection, resolution time, and CSAT.
Your contact center spans multiple geographies and languages outside India.
You want a no-code platform your CX team configures without an engineering team.

For voice AI driving sales conversion in India, yes. For global customer service automation across voice, chat, and email, Yellow.ai's platform is built for that broader job. The honest question is which job the platform is being hired for. Yellow.ai automates customer service across global enterprises with ticket deflection and CSAT as the contracted metrics. SquadStack drives revenue at 3x lower CAC for India's leading consumer brands across BFSI, EdTech, E-Commerce, Travel, Healthcare, Automotive, and Logistics.
Common pattern. Several enterprises run Yellow.ai for inbound customer service automation across web chat, voice, and email, and SquadStack for voice AI agents that augment or replace human callers on high-volume sales campaigns. The two products solve different problems and don't conflict. Yellow.ai automates your customer service operations. SquadStack runs your sales floor at 3x lower CAC than human teams.
The POC runs against actual sales KPIs: connectivity, qualified leads, conversion rate, and CAC. SquadStack runs on the customer's real campaign data and current baseline, with conversion as the contracted KPI. POC success rate has been 93% against an industry average of 25%, on voice campaigns where conversion is the contracted KPI. The deciding factor is usually architectural: a platform optimized for global customer service automation cannot match the conversion performance of a platform built specifically for Indian sales conversations. Different training data, different model tuning, different KPI orientation.
Both companies have proven scale, on different jobs. Yellow.ai runs 1.3 billion+ conversations across 1,100+ global enterprises, primarily on customer service automation. SquadStack runs 40 lakh+ AI sales calls daily for India's leading consumer brands including IndiaMART, JustDial, BankBazaar, KreditBee, IIFL Finance, AngelOne, Eureka Forbes, and TATA AIG. The deciding factor for a sales conversion buyer is which platform has more sales call volume to learn from. SquadStack's voice models are trained specifically on Indian sales conversations, with conversion lift and CAC reduction as the contracted KPIs.
Not for Indian deployments. SquadStack is ISO 27001, ISO 27701, SOC 2 Type II, DPDP, and TRAI compliant, with a stack purpose-built for Indian enterprise BFSI, lending, and consumer brands. For an enterprise running sales campaigns in India, this compliance set covers what regulators require. Yellow.ai's HIPAA, GDPR, and PCI DSS coverage is built for global multi-region deployments where customer data crosses jurisdictions. Different deployment shapes, different compliance requirements.
