Does Aevin really sound human in conversation?

Yes — and you should hear it before deciding. We run two voice engines: OpenAI Realtime for sub-200ms latency, and an ElevenLabs Indic-native voice pipeline for warmth. Independent listeners can't reliably tell within the first 90 seconds. Book a demo and we'll call your number live.

Will Aevin actually replace my SDR team?

It replaces the high-volume top-of-funnel work — inbound triage, outbound prospecting, qualification, follow-ups, calendar booking, CRM hygiene. Most customers keep 1–2 senior reps for closing and let Aevin handle everything before that. The math: a 12-person SDR floor costs ₹92 lakh / year; Aevin's Growth plan delivers the same output for ₹4.8 lakh / year.

How is this different from Yellow.ai, Skit, Bland, or Retell?

Those are voice-only platforms. Aevin ships the full revenue stack — voice agent, chat concierge, AI sales manager, and lead orchestration — on a single conversation brain, deployable in 7 days, with a per-minute price that fits high-volume operations. None of the alternatives do all four products integrated.

Is the model trained on real conversations or generic LLM data?

Real. Our 47-million-conversation corpus is hand-curated from real revenue floors across 14 verticals, in 8 languages, with native annotators. We do not fine-tune on public scrape. The production model fine-tunes every 72 hours against your own deployment's top-scoring turns.

Is Aevin TRAI and DPDP Act compliant?

Yes. Whitelisted caller IDs, DND-aware dialling windows, AI disclosure on every connect, full recording archive, Indian-datacenter residency. Enterprise tier includes a DPDP compliance pack, signed DPA, and security review. SOC 2 Type II is in audit; ISO 27001 controls are in place.

What CRMs does Aevin connect to?

Native connectors for HubSpot, Salesforce, Zoho, LeadSquared, Kylas, Pipedrive, Freshsales. Anything else, webhook with a clean JSON payload. Every conversation leaves a transcript, summary, sentiment, intent score, and next-action behind in your system of record.

How long does deployment take?

Production pilots are live in 5–7 working days. Day 1–2: knowledge ingestion and voice tuning. Day 3–4: number provisioning and CRM hookup. Day 5: shadow calls with your team. Day 6–7: full production with an Aevin engineer on standby.

What happens when Aevin can't answer something?

Two escape hatches. (1) Live human handoff — Aevin conferences your rep mid-call with the full transcript already in their hand. (2) Promise-to-callback — Aevin schedules the callback on a rep's calendar and confirms on WhatsApp. The lead never gets dropped.

Where are recordings and data stored?

Indian datacenters by default (AWS Mumbai / GCP Mumbai / Azure Pune). 30 days on Launch, 90 days on Growth, configurable on Scale and Enterprise. Recording can be disabled entirely for transcript-only deployments. EU/US residency available for enterprise.

Is there a free pilot?

Yes — a 7-day production pilot with 200 free minutes, no card required. We set up one caller ID, one language, one CRM hookup. If you don't see ROI inside the week, you walk away with no obligation.

01The cost of an unanswered conversation

Every unanswered conversation is a competitor’s signed deal.

Revenue teams answer 38% of inbound interest inside 60 seconds. The remaining 62% — voicemails, late-night messages, abandoned forms, after-hours callbacks — quietly migrate into the funnel of whoever picked up first. Hiring more humans is linear. Conversation infrastructure is exponential.

What Aevin replaces

Replace a 12-person revenue floor. Bill at SaaS rates.

A traditional inbound + outbound revenue operation needs SDRs, BDRs, telecallers, a sales ops analyst, and a manager — minimum. Aevin replaces all of it, runs 24×7, never quits, never has an off-day. Here's the line-item math, before software discounts.

Engineering, not assembly

Why Aevin isn’t another voice bot.

Most voice AI vendors wrap a generic LLM in a phone number and ship. Aevin is purpose-engineered — a proprietary dialogue corpus, a sub-200ms speech architecture, and a continuous-learning loop that fine-tunes every 72 hours.

Proprietary corpus

47 million hand-curated conversations from real revenue floors across 14 verticals, with native annotators in eight languages. Three years of curation, not public-scrape fine-tuning.

Real-time speech

Sub-200ms median end-to-end latency, p99 under 480ms. Competitors run 800–1200ms. We achieve this through edge-deployed inference, streaming TTS, and a custom VAD that interrupts cleanly.

Continuous learning

Every production call is scored by an LLM critic against 10 deterministic metrics. Top-scoring turns auto-promote into a vector RAG that fine-tunes the model overnight. Compound weekly improvement.

Compliance native

DPDP Act, TRAI, ISO 27001. SOC 2 Type II in audit. AI disclosed on every connect, DND-aware, audit-archived. Indian datacenter residency. Full DPA for enterprise.

04 · How Aevin works

From first signal to booked deal, in five honest steps.

No 90-day implementations. No discovery calls that mysteriously add zeroes to the quote. Here’s exactly what happens after you say yes.

01
Every channel routes in
Inbound call, missed-call ping, WhatsApp, Instagram DM, Meta Lead Ad, web form — all of it hits the same Aevin brain. Zero leakage at the funnel mouth.
02
Sub-200ms response
Voice picks up before the second ring. Chat replies in two seconds. Both surfaces speak the customer's language and read the unified memory.
03
Qualify, score, enrich
Fourteen intent signals graded in real time. Budget, timeline, sentiment, named entities, micro-pauses, language choice. No hot/cold guesswork.
04
Route to the right human
Aevin Pipeline lands the lead on the right rep — by language, geography, ticket size, current capacity. Books the meeting. Drops a WhatsApp confirmation.
05
Learn from every turn
Every conversation gets scored. Top-scoring turns auto-promote into next week's playbook. The model fine-tunes every 72 hours. Compound improvement.

08What customers say

Don’t take our word for it.

We obsess over call-quality scores so our customers don’t have to. Three said this unprompted.

We stopped losing 6pm-to-10pm enquiries inside one week. Aevin booked twenty-seven site visits in its first weekend — more than my two best reps combined. Six weeks in, we shut down outbound dialling entirely.

Rohit Khanna·Head of Sales, ODH Developers·Kanpur

Patients can't tell. That is the highest compliment I can pay an AI. Our front desk reclaimed seven hours a day; no-shows dropped a third. We redeployed two staff to actual clinical work.

Dr. Priya Saxena·Medical Director, Yamuna Hospitals·Lucknow

We piloted two enterprise platforms before Aevin. Six-figure quotes, ninety-day implementations, nothing in production. Aevin went live on day six. The cost line on the P&L is a rounding error against what we used to spend on telecallers.
