BFSI-only voice AI specialist vs horizontal platform with BFSI depth.
Two India-focused voice AI vendors — how they compare on BFSI use case depth, RBI/DPDP/IRDAI compliance, language coverage, pricing and deployment cadence.
Caller Digital is an India-first AI voice agent platform that handles outbound and inbound customer calls end-to-end in Hindi, Hinglish and 13 Indian languages. Sub-200ms latency, DPDP-aligned, TRAI DLT-registered and RBI Fair Practices Code-compliant by default. Native integrations with Salesforce, HubSpot, Zoho, LeadSquared and major Indian telephony providers (Plivo, Exotel, Knowlarity, Ozonetel, Tata Tele, Twilio). Built for Indian D2C, BFSI, healthcare, logistics, real estate and edtech teams running between 1,000 and 10,000 daily calls.
Recent production deployments include Finance Buddha (fintech / personal-loan marketplace), College Vidya (online education), Rungta College and JECREC (engineering education), Nuface (D2C beauty), Teru Energy (clean energy), and XORvant (B2B SaaS) — across lead qualification, EMI reminders, COD verification, demo booking and appointment workflows.
vs GreyLabs AI: GreyLabs AI is a vertical specialist focused exclusively on BFSI — banks, NBFCs, insurers and fintechs. Caller Digital is a horizontal voice AI platform with documented BFSI depth (EMI reminders, NBFC collections, insurance renewals, V-CIP nudges) plus optionality for D2C, healthcare, logistics and education when ops teams need to extend later.
This comparison is written and maintained by the Caller Digital team. We have a stake in the outcome — we have tried to keep the GreyLabs AI side accurate and fair, but you should read it as a vendor-authored comparison and verify specifics with GreyLabs AI directly before deciding.
Best strategy for most Indian BFSI buyers: Caller Digital for mid-market NBFCs and fintechs that may extend horizontally, GreyLabs for large banks with strictly BFSI-only mandates.

Indicative ranges. For NBFCs with consistent month-on-month volume, both models converge. For NBFCs with seasonal volume swings, per-outcome pricing avoids paying for unused capacity.
GreyLabs AI is a vertical specialist — its product, content, case studies and go-to-market are built exclusively for BFSI institutions (banks, NBFCs, insurers, fintechs) covering sales, collections and support. Caller Digital is a horizontal voice AI platform with documented depth in BFSI (EMI reminders, NBFC collections, insurance renewals, V-CIP reminders) as well as D2C, healthcare, logistics, real estate and education. If a buyer is BFSI-only and wants a vendor with no horizontal distraction, GreyLabs is a clean choice. If a buyer wants BFSI depth plus the option to extend the same platform to adjacent verticals later, Caller Digital is more flexible.
Both publish BFSI-aligned compliance — RBI Fair Practices Code, DPDP 2023 consent, TRAI DND scrubbing, DLT template management, IRDAI master circular alignment for insurance. GreyLabs as a vertical specialist has BFSI compliance as its only compliance posture, which buyers sometimes interpret as deeper. Caller Digital publishes documented architecture for the same regulations and adds sector overlays for healthcare (clinical data handling) and D2C (consumer-facing scripts) — buyers should evaluate on documented controls rather than positioning.
GreyLabs AI supports core Indian languages aligned to BFSI customer bases — primarily Hindi, English, Tamil, Telugu, Marathi, Bengali, Gujarati. Caller Digital supports Hindi plus 13 Indian languages including Bhojpuri-influenced Hindi, Awadhi, Marwari and Punjabi using in-house models trained on Indian telephony audio. For BFSI buyers with Tier 1 and Tier 2 borrower bases, both cover the languages that matter; for NBFCs collecting in Tier 3 markets with regional dialects, Caller Digital's regional dialect coverage holds up better.
Both target EMI reminders and collections. GreyLabs has BFSI-only focus which means its product team prioritises BFSI features. Caller Digital has a dedicated /use-cases/emi-payment-reminders page, RBI Fair Practices Code overlay built in (call-hour windows of 8 AM-7 PM, no-harassment scripting, promise-to-pay capture), and integrations with major LMS platforms (Finflux, Nucleus FinnOne, LoanTap). Differentiator: ask both vendors for documented architecture on call-hour enforcement, harassment-detection scripting, and LMS write-back patterns — buyers should compare evidence not claims.
GreyLabs AI typically prices on enterprise BFSI contract terms — annual licensing with usage tiers, sometimes with on-premise or VPC deployment add-ons. Caller Digital prices per dispositioned outcome on AI calls (Rs 8-25 per resolved contact, no charge on unconnected attempts) with optional enterprise contracts for BFSI buyers needing VPC isolation. For NBFCs running 50,000+ calls/month with variable connection rates, per-outcome typically lands more predictable than annual licensing tiers.
GreyLabs has positioned exclusively around BFSI. Non-BFSI use cases like D2C COD verification, cart abandonment, hospital appointment reminders, restaurant booking, or logistics NDR are not its product focus. Caller Digital has dedicated industry depth across D2C (COD, cart, NPS), healthcare (appointment reminders, no-show recovery), logistics (NDR, address resolution), real estate (lead qualification, site visits) and education (counselling, fee reminders). For a buyer who is sure they will only ever need BFSI calls, GreyLabs is fine. For buyers who may extend to adjacent ops later, Caller Digital's horizontal coverage avoids vendor lock-in.
Both can pilot a single use case in 2-4 weeks. Caller Digital publishes a documented 2-3 week implementation timeline with a dedicated implementation manager handling LMS integration, DLT template registration, DND scrubbing and pilot KPI tracking. GreyLabs as an enterprise BFSI vendor typically runs a longer pre-pilot procurement cycle (security review, vendor onboarding, MSA) that adds 2-4 weeks before pilot kickoff. For NBFCs that want to start dialling in 3 weeks, Caller Digital's mid-market deployment cadence is faster; for large enterprise banks with mature procurement, GreyLabs' enterprise posture fits established workflows.
Yes. Most BFSI migrations run as a parallel pilot on one workflow (typically EMI reminders or KYC reminders), pointing a slice of the LMS at Caller Digital alongside the existing GreyLabs deployment for 4-6 weeks. Comparison metrics: cost per resolved contact, connection rate, promise-to-pay capture rate, time-to-payment after PTP, and audit-trail completeness for RBI inspection. Caller Digital's implementation manager handles LMS connector setup, DLT template re-registration if needed, and DND scrubbing during pilot. Most NBFCs complete migration of a single workflow within 4-5 weeks of pilot kickoff.
