Best Fit For
SquadStack.ai:
Indian enterprises running outbound voice AI for sales, lead qualification, and conversion at scale
Bolna.ai:
Developers and small teams building voice agents in-house with no-code or API
You're hiring a partner to deliver sales conversion outcomes, not a platform for your team to build on.
You're driving sales conversion at scale for India's consumer brands.
You need voice AI trained on real Indian sales conversations across regional languages.
Your KPIs are conversion lift, CAC reduction, and connectivity.
You want a team of forward-deployed engineers owning your business metrics.
You have an ops or engineering team to build and run voice agents yourselves.
Your use cases are recruitment screening, appointment booking, or customer support.
You're comfortable connecting your own STT, TTS, and LLM providers and managing the integration.
Your KPIs are call completion rate, screening efficiency, and recovery rate.
You want a no-code playground and hosted APIs to ship voice agents in days.

Bolna and SquadStack solve different problems. Bolna sells a voice AI platform for Indian enterprises to build agents on, across recruitment, support, collections, and scheduling. SquadStack delivers sales conversion outcomes for India's leading consumer brands. Both are voice AI for India. The difference is whether you're hiring a platform for your team to build with, or hiring a partner to run your sales floor.
For light, transactional use cases like recruitment screening, appointment booking, and collections reminders, the answer might be yes. Bolna's no-code playground and hosted APIs let an ops or product manager ship a voice agent in days. SquadStack is built for a different buyer: enterprises where sales conversion is a contracted business outcome. The forward-deployed team owns the agent build, the campaign optimization, and the conversion metric on behalf of the customer. The buyer is a CRO or VP Sales, not an ops manager scoping a flexible platform.
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% (23 of 25 structured evaluations) against an industry average of 50-60%. With Bolna, your team builds the voice agent on top of orchestrated third-party APIs and owns the outcome. With SquadStack, the forward-deployed team builds and runs the agent and contracts on the conversion delta. Different commercial models, different KPI orientations.
Three architectural differences. First, model ownership: SquadStack builds its own STT trained on 5M+ hours of real Indian sales calls, its own TTS with 1000+ cloned Indian agent voices, and runs proprietary fine-tuning on the LLM layer. Bolna orchestrates third-party speech and LLM APIs from Deepgram, Azure, OpenAI, ElevenLabs, and others, with customers typically bringing their own provider accounts. Second, who runs the agent: with Bolna, your team builds the workflow, connects providers, writes prompts, monitors calls, and optimizes over time. With SquadStack, a forward-deployed team builds the agent, runs the campaigns, and contracts on the conversion metric on your behalf. Third, target outcome: SquadStack delivers 40% more conversions and 3x lower CAC on sales campaigns. Bolna sells platform consumption priced per minute, with the customer's team owning the conversion outcome.
Both platforms serve Indian enterprises, on different use cases. Bolna's published customer stories center on recruitment (Awign, Hyreo, Futwork), e-commerce ops (GoKwik), and collections (Hypothesis recovered ₹2.5 Cr+). SquadStack lighthouse accounts are sales conversion deployments: IndiaMART (₹74L+ MRR, 6 use cases live, won head-to-head against Sarvam, Origa, Hampam, Gnani), BankBazaar ($1M ARR in 3 months across 3 bank partners, won against Gupshup and Gnani), JustDial (1.5x conversion lift, won against Sarvam, GreyLabs, Convin, Convozen). The deal pattern is land at $100K+ ARR and expand to $500K-$1M+ within 6-12 months, contracted on outcome metrics like conversion rate and CAC.
