Retell builds voice agents. Rootle delivers outcomes.
Rootle is a KPI-first Voice AI built on Conversational OS, not a developer toolkit you have to engineer into a business result. Every call drives cost-per-hire down, first-call resolution up, and revenue forward, with nothing to build from scratch.

Voice AI built around business outcomes.
Retell gives you the building blocks for a voice agent. Rootle's Conversational OS goes a layer deeper, arriving with the workflows, integrations, and outcome tracking already built in.
KPI-first by design
Every call is measured against business metrics including cost-per-hire, first-call resolution, and conversion rate, outcomes your leadership team actually cares about, not just latency and turn-taking benchmarks.
No prompt engineering required
Pre-built conversation flows for recruitment, support, sales, and collections, tuned and ready to deploy, rather than a blank agent you have to prompt, test, and retune call by call.
Pre-built integrations, zero code
Native connectors for leading ATS, CRM, and helpdesk platforms. Data flows bidirectionally, with no custom webhook logic, no middleware, and no ongoing engineering maintenance required.
Outcome tracking from day one
Most agent-builder platforms give you call transcripts and latency logs. Rootle gives you a KPI dashboard tracking what each call produced against your business goals, live from launch.
Rootle vs. Retell AI, a clear-eyed look
Both platforms operate in the voice AI space. Here's how they compare across the dimensions enterprise teams care about most.
| Rootle — KPI-First Voice AI | Retell AI — Voice Agent Builder | |
|---|---|---|
| Primary focus | Outcome-driven Voice AI, built to move business metrics forward | Developer platform and API for building custom voice agents |
| Getting started | ✓ Pre-built workflow templates, configured to your KPI targets | Requires prompt engineering, flow design, and testing per use case |
| KPI dashboard | ✓ First-call resolution, cost-per-hire, conversion rate, all built into the platform | Call logs, latency, and transcripts; business KPIs typically via external tools |
| Conversational memory | ✓ Context retained across turns, sessions, and channels | Session-level memory configurable by the developer per agent |
| CRM / ATS sync | ✓ Pre-built, bidirectional connectors, zero custom code | Webhook and function-calling based; integration built by your team |
| Languages | ✓ 31+ languages with deep Indian regional voice support | Primarily English and major global languages via underlying LLM/TTS stack |
| Compliance (India) | ✓ TRAI-compliant by default, DLT and consent handling included | Not India-specific; regulatory compliance is the implementing team's responsibility |
| Pricing model | Usage-based pricing that is transparent and outcome-linked | Per-minute API pricing plus your own hosting, LLM, and telephony costs |
| Best suited for | Enterprises measuring voice ROI across recruitment, support, sales, and collections | Engineering teams building bespoke voice products from the ground up |

Book a DemoWhat does "KPI-first" actually mean?
It means every call is designed, measured, and optimized around business outcomes rather than raw call volume or model latency. Rootle's Conversational OS connects your voice channel to the metrics leadership actually reports on.
How Rootle delivers outcomes
A purpose-built stack connecting voice conversations to business results, without requiring an engineering team to assemble the pieces yourself.
Set your KPI targets
Tell Rootle what success looks like: cost per qualified candidate, first-call resolution rate, conversion percentage. The system is configured around your goals, rather than a prompt you write from a blank canvas.
Connect your stack
Choose from pre-built workflow templates for recruitment, support, or collections. One-click connectors sync with your CRM and ATS, with no webhook wiring, no custom code, and no integration backlog to manage.

Rootle packages everything an enterprise needs to run outcome-driven voice AI, so your teams focus on results, not agent tuning.
Conversational OS
A proprietary orchestration layer connecting intent detection, memory, task execution, and CRM sync into a single coherent voice agent, rather than a set of building blocks you assemble yourself.
Outcome-linked call design
Workflows structured around business goals. Each dialogue path is optimized for resolution, conversion, or qualification, rather than just successful call completion.
Emotion-aware voice
Voice agents that detect caller mood in real time, adapt their tone and pacing, and seamlessly escalate to a human agent when the situation demands empathy over automation.
Bidirectional CRM sync
Every call outcome, candidate status, issue resolution, and lead score writes back to your ATS, CRM, or helpdesk automatically, with no manual data entry, no lag, and no export-import cycles.
Real-time KPI dashboard
A single screen showing first-call resolution, cost-per-hire, campaign conversion, and agent handoff rates, updated live, rather than logs you have to build your own reporting layer around.
TRAI-compliant by default
Built for the Indian regulatory environment, covering DLT registration, outbound compliance, and data handling under Indian privacy frameworks. Compliance documentation included at onboarding.
Switch to Rootle if you're in any of these situations
Purpose-built for high-stakes enterprise use cases. Here is where it consistently delivers outsized ROI.
Screening 500+ candidates a week?
Your recruiters are spending 60% of their time on calls that could be automated, including pre-screening, availability checks, scheduling, follow-up. Rootle handles all of it at scale, in multiple languages, with full ATS sync. You get a cost-per-hire dashboard that finally tells you what screening is actually costing you per qualified candidate, without a custom-built agent to maintain.
Learn moreFirst-call resolution rate below target?
Most support call failures happen because context is lost in transfer. The customer repeats themselves three times and still doesn't get resolved. Rootle's voice agent resolves Tier-1 queries autonomously, routes complex issues with full conversation context, and tracks resolution rate per product category in real time, with no in-house prompt tuning required.
Learn moreLeads going cold before a rep touches them?
The window between a form submit and a live sales conversation is shrinking. Rootle's outbound voice agent qualifies inbound leads within minutes of submission, updates your CRM with intent scores, and hands off warm, context-rich leads to your sales team so they focus on closing, not on maintaining an in-house agent build.
Learn moreNeed empathetic, compliant outbound at scale?
Debt communication requires tone awareness, regulatory precision, and consistent follow-through, three things that are hard to guarantee from a self-built agent. Rootle's TRAI-compliant voice agents handle collections outreach with configurable escalation logic, outcome tracking per contact, and the kind of consistency that reduces compliance risk while improving recovery rates.
Learn moreReal outcomes from real deployments
Rootle replaced our entire screening flow with a voice agent that screens, scores, and schedules, and we finally have a dashboard that tells us what it's costing us per qualified candidate. We never had to write a single prompt.
Rootle resolves calls and tells you which resolution paths work best. We went from reporting call volume to reporting outcomes, and that is the real shift in how we run our support operation.
We evaluated building on a raw voice agent API. The engineering cost and timeline killed that option. Rootle had us live in seven days with pre-built workflows and the integrations we needed already there.
