Our Story

How Kolsetu Began

“

Kolsetu was founded in late 2024 by Virendra and Ben, two operators who had spent years building technology for regulated industries in Europe.

They saw the same pattern everywhere: enterprises drowning in inbound calls, fragmented across channels, and losing revenue every hour their phones went unanswered. Existing automation was too brittle for regulated workflows and too generic for real enterprise needs.

So they built Elba: an AI workforce purpose-built for regulated enterprises. Not a chatbot. Not a call-centre tool. A compliant, multilingual AI agent that handles voice, WhatsApp, SMS, and email with the security posture these industries demand.

We exist to give regulated teams their time back, without compromising on trust.

Today Kolsetu serves emergency assistance providers, insurers, healthcare organisations, and financial institutions across Europe. Elba speaks over 100 languages, runs on ISO 27001-certified infrastructure, and goes live in weeks, not months.

If you've ever felt blocked by a system that didn't listen, Elba is for you.
