Built For Indian Businesses

A local team that understands your customers — backed by the same enterprise AI platform we build for global clients. Not just WhatsApp: voice, CRM, web and apps too.

Full-Stack, Not Just WhatsApp

WhatsApp is one channel we automate — we also build voice AI agents, CRM integrations, lead generation systems, internal apps and full SaaS products.

Hindi & Bengali Native Support

Your customers type and speak in Hindi, Bengali, English — or a mix of all three. Our AI agents understand and reply naturally in whichever language your customer uses.

Official WhatsApp Business API

Where we do build on WhatsApp, we only use Meta-approved WhatsApp Business API — never unofficial tools that risk getting your number banned.

Same Time Zone, Fast Response

Our team is based in Kolkata. No time-zone delays, no overseas call centres — just direct, fast communication with the people building your AI agent.

Trusted by West Bengal Businesses

From restaurants to nurseries to clinics, West Bengal businesses use Evynta AI agents every day.

Fast Delivery

Simple AI agents go live in about a week. Even our most advanced voice, RAG and CRM builds launch in a matter of weeks, not months.

30 Days Free Support

Every project includes 30 days of free post-launch support, with ongoing maintenance plans available to suit your budget.
