ARCA vs SquadStack: Which Voice AI Platform Fits Your Business?

SquadStack is the most visible voice AI platform in India right now. If you are evaluating voice AI for your enterprise, SquadStack has probably come up in your research. ARCA by Tenori Labs is a different platform, built for a different set of problems. This is an honest comparison. We will tell you where SquadStack is stronger, where ARCA is stronger, and where your specific needs should drive the decision.

The fundamental difference

SquadStack is an outbound sales and support platform that combines AI voice agents with human telecallers. Their model is hybrid: AI handles what it can, humans handle the rest, and the platform manages the entire workflow. Their STT model Arth is trained on 600 million plus minutes of real Indian telephony audio. ARCA is a pure AI voice agent platform. No human telecaller layer. The agent handles calls end to end in 22 Indian languages with sub 500ms response time and native code switching. It deploys through 2 week pilots. This is not a subtle difference. It shapes everything: pricing, scaling, use cases, and what kind of enterprise each platform serves best.

Language coverage

SquadStack handles multiple Indian languages through their Arth STT model, which is trained on massive telephony data. The language coverage is strong for major Indian languages. ARCA handles 22 Indian languages and 20 international languages with native code switching. Code switching means a caller can mix Tamil and English mid sentence (which is how most Indians actually speak) and the agent follows naturally without delays or misunderstanding. If your customer base is primarily English and Hindi, both platforms handle it well. If your customers speak Tamil, Telugu, Kannada, Bengali, Marathi, Gujarati, Malayalam, or other regional languages and frequently mix them with English, ARCA's native code switching is a meaningful advantage.

Deployment model

SquadStack deployments typically involve campaign setup, telecaller team provisioning, script development, and quality assurance setup. The hybrid nature means there is both an AI and a human operations component to stand up. ARCA deploys through a 2 week pilot model: one workflow, configured and live on real customer calls in 14 days. No human telecaller provisioning. No campaign team staffing. The pilot proves ROI before broader commitment. If speed to deployment matters (and for most enterprises evaluating voice AI, it does), ARCA's model is faster to first live call.

Pricing

SquadStack's pricing reflects the hybrid model. You are paying for AI infrastructure and human telecaller capacity. This makes it more expensive per call than pure AI, but you get human handling for calls the AI cannot manage. ARCA's pricing is usage based (per minute of AI call time). No human layer cost. The cost per resolved interaction is lower, but calls the AI cannot handle escalate to your existing team rather than to SquadStack's telecallers. The right economic comparison is total cost per resolved interaction, not per call price. If your call mix is 60 to 70% automatable, ARCA's pure AI model is more cost effective. If your call mix requires significant human handling (complex sales, negotiation, relationship building), SquadStack's hybrid model may deliver better outcomes despite higher per call cost.

Use case fit

SquadStack is strongest in: High volume outbound sales campaigns (insurance, lending, ecommerce) Lead qualification at scale where some calls need human closers Scenarios where the AI plus human handoff is frequent and valuable ARCA is strongest in: Multilingual enterprise communication (education admissions in 6 languages, BFSI collections across India, healthcare in regional languages) Inbound customer support and appointment scheduling Outbound campaigns that are highly structured (reminders, follow ups, confirmations) Enterprises that want pure AI with no external telecaller dependency

Scale

SquadStack processes 50 lakh plus calls per day across their platform. This is proven massive scale with named enterprise clients. ARCA handles 170,000 plus calls with a 99.9% autonomous rate. The absolute scale is smaller (Tenori Labs is a younger company), but the autonomous handling rate is exceptionally high. If your immediate need is millions of calls per day and you need proven scale, SquadStack has the track record. If your need is thousands to hundreds of thousands of calls per month with maximum automation and language coverage, ARCA delivers.

Compliance

Both platforms support enterprise compliance requirements. SquadStack has enterprise grade security and compliance for regulated industries. ARCA is built with DPDP and RBI compliance from the ground up, with tamper proof audit trails and policy bound conversation flows. For BFSI specifically, both platforms are credible. ARCA's policy bound flows (where the agent cannot deviate from approved scripts) may be an advantage for highly regulated conversations.

The honest summary

There is no universally better platform. The right choice depends on your situation: Choose SquadStack if: You need massive outbound scale, your calls frequently need human handling, you want a hybrid AI plus human model, and you are in insurance, lending, or high volume ecommerce sales. Choose ARCA if: You need deep Indian language coverage with code switching, you want pure AI without a telecaller layer, you need fast deployment (2 weeks), and you are in education, healthcare, real estate, government, or BFSI collections. Choose both if: You have different workflows with different needs. Some enterprises use one platform for outbound sales and another for inbound support.

How to decide

Do not decide based on this comparison alone. Run a pilot on both platforms with your actual customer calls, in your actual languages, on your actual workflows. Compare the results. At Tenori Labs, we offer 2 week pilots specifically so you can test before committing. If SquadStack offers the same (or a proof of concept), take them up on it too.
