The problem

Indian customers don't read your retargeting email. They don't open WhatsApp from unknown numbers. They pick up the phone — if you call them well, in their language, at the right time. Most voice tools were not built for that call.

The cast · छह आवाज़ें

Six voices, one platform. Pick the one that fits your call.

Each agent is a template. You set the script, KB, and tools — Sargam tunes the voice, timing, and turn-taking for the use case.

What Sargam does

Three notebook pages, in plain English.

  1. I≈ 90 seconds

    Pick a template — Cart Recovery, Lead Qualifier, IVR Greeter. Drop in three lines of brief, pick a voice, plug a number.

  2. II1 dashboard

    Launch

    Upload a CSV, schedule a campaign, or wire to your existing webhook. Sargam handles concurrency, retries, DND windows, and consent.

  3. IIIEvery call

    Listen

    Every call is recorded, transcribed, sentiment-scored, and routed back to your CRM as structured outcomes — recovered, callback, DNC, wrong number.

Under the hood · तीन तले

Three planes. One process boundary. Zero rewrite to scale.

Sargam runs as three independent services on day one — control, media, analysis. They talk only through Postgres and Redis, so when you outgrow a single VM, each plane peels off without a code change.

Control plane

Django 5 · DRF · Celery

  • Auth · multi-tenancy · billing
  • Agent + workspace CRUD
  • Webhook OUT delivery
  • Batch scheduling

Media plane

FastAPI · Pipecat · WebSocket

  • Per-call WS from Plivo/Meta
  • STT → LLM → TTS pipeline
  • Transcript streaming
  • 780ms p50 turn

Analysis plane

FastAPI · Celery workers

  • Standalone audio/transcript API
  • Sentiment · intents · entities
  • Separate billing meter
  • Sold to non-Sargam dialers too

Postgres 16

source of truth · pgvector for KB · RLS per tenant

Redis 7

Celery broker · pub/sub `call.ended` · rate limits

Scale-up: 15 concurrent calls → upsize VM · 30 → managed PG/Redis · 60 → split media plane · 200 → AKS. Documented, not improvised.

For marketing agencies · संस्थाओं के लिए

Resell Sargam.
Keep your margin. White-label everything.

Sargam was designed so a marketing agency can ship voice to a client in an afternoon — onboard the client as a workspace, brand it as your own, set the retail price, and we'll bill you at wholesale.

Rollup dashboard
Every workspace under your agency — revenue, calls, agent health, low-balance alerts — in one view. Drill down with one click.
Your domain
Run Sargam from app.your-agency.com with your logo, colors, support address. Clients never see Sargam's brand unless you want them to.
Your invoice
Charge clients off-platform at your retail price; Sargam bills you wholesale monthly. Or pass-through, take a commission — your call.

The honest comparison · सच

Sargam vs Bland vs Vapi vs DIY.

We built Sargam because the US-built platforms speak Indian English with an American accent. Here's where the numbers land.

From the pilots

We replaced two telecallers with one Sargam agent and our recovery rate went up. Customers told us they thought it was a real person — that's the bar that mattered.

The Hindi voice is the only one I've heard that doesn't sound like an English speaker reading transliteration. That alone is the product.

Why we built this

India's best businesses still cannot reach their own customers in their own language at scale. Email open rates are flat. WhatsApp marketing is a queue you wait in. Phone calls work — but no one has built a voice tool that an Indian customer actually wants to take.

So we did. Self-hosted Hindi voices that don't sound like transliteration. Agency-first delivery so the people closest to the customer can resell it. Billed per second so an 8-second call costs eight seconds. Built in Bangalore by people who answer Sargam calls themselves to know they work.

We're not a labs project. We're a product. We answer calls all day.
