AI Lead Qualification That Qualifies and Routes Every Lead

5.0

Stars

Retell AI takes the complexity out of lead qualification by automating the process, engaging prospects in natural conversations, and determining their readiness and interest level quickly and effectively — then routing hot leads to the right rep so your team spends its time closing, not screening.

Trusted by over 3,000 businesses powering 30+ million calls per month.

How It Works

Go from build to a live call in a day, on your existing number.

Build the agent

Point the agent at your offers, pricing, and qualification criteria through a knowledge base that syncs as that content changes. Define the call flow with a drag-and-drop builder — greeting, intent detection, qualification questions, routing rules, and transfer conditions — then connect your calendar and CRM. No engineering team is required for a standard agent.

Test against qualification scenarios

Run the agent through simulation against common scenarios before it touches a real prospect: a strong-fit lead, a poor-fit lead, a caller who won’t share budget, and an ambiguous inquiry. Each run scores accuracy and shows where the agent guesses instead of looking up, so you fix the flow, rerun, and validate at volume.

Connect your line and go live

Connect your line through SIP trunking and forward calls to the agent — all of them, only the ones you miss, or only after hours — and set the routing and human-escalation rules. Go live, confirm your qualification and transfer rates, then expand. Your existing carrier and phone number stay in place.

Monitor and retrain

Every call is transcribed, summarized, and tagged by outcome, and every qualified lead lands in your CRM. Watch qualification rate, transfer rate, and speed-to-lead in a dashboard, catch the questions the agent fumbles, and retrain the flow, with quality review across 100% of calls rather than a small sample.

Use Cases

How AI lead qualification works across your call flow

Qualify inbound leads on every call

The agent picks up the moment a lead calls, identifies why they’re phoning, and qualifies them in natural conversation against your criteria, so no inbound lead sits in a queue or rolls to voicemail — even at nights, weekends, and peak volume.

Route hot leads with a warm transfer

The agent gathers the details you need and routes hot leads to the right person with a warm call transfer that attaches the full transcript, so sales reps pick up a qualified, context-rich conversation instead of starting cold.

Sync qualified leads to your CRM

Retell AI integrates with popular CRM platforms and sales tools, transferring qualified leads directly into your existing workflows and keeping all lead information organized in one place.

Qualify across phone, text, and email

Retell AI interacts with leads across multiple channels, including phone, text messages, and email, so you can capture and qualify leads wherever they reach out and expand your reach.

Follow up and re-engage by phone

The agent runs follow-up, nurture, and re-engagement calls through batch call campaigns, reaching aged or unworked leads at scale and logging every outcome to your CRM with the transcript attached.

Capture leads after-hours and on overflow

When your team is busy or offline, the agent fields overflow and after-hours inquiries so a lead that arrives at 9 PM on a Saturday is qualified and routed instead of lost to a competitor who answered first.

Compliance

Regulated businesses route real calls through the agent, so the security baseline comes standard.

SOC 2 Type II

Call data runs on SOC 2 certified infrastructure, ensuring that all interactions and stored lead data meet rigorous security, availability, and confidentiality requirements.

HIPAA

Retell is HIPAA-compliant, making it safe for regulated teams, with a self-service BAA portal available from the dashboard. Sensitive information is always encrypted and protected.

GDPR

For global businesses, Retell AI guarantees full GDPR compliance, covering consent and access rights so personal data handled by the agent is managed transparently and securely.

PII Redaction

Built-in PII redaction ensures sensitive customer information never gets exposed, automatically masking personally identifiable data in transcripts and recordings, alongside single sign-on and role-based access.

FAQ

Frequently asked questions.

What is AI lead qualification?

AI lead qualification uses a voice agent to call or answer leads, run a real qualification conversation, and decide whether each one fits your criteria — then capture the details and route the qualified ones to a rep. Unlike a static web form or a touch-tone menu, it understands intent, asks follow-up questions, and takes action during the call, applying the same discovery framework to every lead, 24/7.

How does Retell AI know if a lead is qualified?

Retell AI uses your specified criteria to evaluate each lead’s responses, such as budget, project scope, and timeline. It tailors its questions to gather relevant information and only qualifies leads that match your ideal profile.

Will Retell AI work with our CRM or sales tools?

Yes, Retell AI can integrate with popular CRM platforms and sales tools, making it easy to transfer qualified leads directly into your existing workflows. This seamless integration saves your team time and keeps all lead information organized in one place.

Can Retell AI support multi-channel lead qualification?

Yes, Retell AI is designed to interact with leads across multiple channels, including phone, text messages, and email. This flexibility means you can capture and qualify leads wherever they reach out, improving the customer experience and expanding your reach.

How much time does Retell AI save for sales teams?

Retell AI reduces the need for manual lead screening, often saving sales teams hours per week. By handling repetitive tasks and providing qualified leads, it allows your sales team to focus more on closing and nurturing relationships with serious prospects.

How much does it cost?

Retell is pay-as-you-go at $0.07 per minute with no platform fee or contract, plus free credit to start. You pay for minutes worked, not seats, which is why a busy line still costs less than a part-time SDR. For companies with large volumes, or data, deployment, or support requirements, an Enterprise plan adds white-glove service, a dedicated solution engineer team, and custom pricing and concurrency.
