Our Mission
To empower businesses across India with end-to-end customer acquisition solutions that turn every lead into a loyal, paying customer — maximizing ROI at every stage of the funnel.
About Quantum Tech
We're on a mission to help Indian businesses acquire, nurture, and convert customers through the perfect blend of AI automation and human expertise.
Our Story
From Kolkata Startup to India's Conversion Leader
Founded in 2018 in Kolkata, Quantum Tech began with a simple observation: most marketing agencies stop at lead generation, leaving businesses with pipelines full of unconverted prospects. We set out to fix that gap.
What started as a small team of performance marketers has grown into a 150+ person organization serving 500+ clients across Finance, Real Estate, EdTech, SaaS, Healthcare, and more. Today, we own the entire customer acquisition funnel — from the first ad impression to the final purchase confirmation.
Our hybrid AI + human model has generated over 2 million qualified leads and helped clients achieve an average 42% conversion rate — transforming how Indian businesses think about customer acquisition.
Built for Indian Businesses
Headquartered in Kolkata with operations across India, we understand the unique challenges of acquiring customers in diverse markets — from metro cities to tier-2 towns, in English and regional languages.
