What they do

Supersei is an AI sales engine that automates lead qualification and booking

The company launched the product, built by founders with sales experience, as an internal tool

Early deployment showed response time drop from 6 hours to under 1 minute

Supersei launched as an AI growth engine by The Next Door AI Pvt Ltd.
The product is an AI sales engine, not a CRM (customer relationship management system).
Its core AI, named Sei, acts as an AI sales rep that responds in seconds.
Sei qualifies leads, books meetings, and shares payment links automatically.
Supersei pulls enquiries from websites, Meta Ads, Google Ads, WhatsApp, and inbound calls into one workflow.
It integrates with Gmail, Google Calendar, Google Meet, Razorpay, and Stripe.
The founders built Supersei as an internal tool to solve their own scaling problems.

The product is positioned as an action-driving tool, unlike traditional record-keeping CRMs.
Founders have a decade of sales and growth experience and previously built their own B2C business.
Early deployment results showed significant improvements in sales efficiency.
