Our Origin Story
FOUNDER'S STORY

The Idea That Started It All

"Many children in rural government schools were attending regularly but struggling to truly understand what they were being taught."

— Founder, Kalvi40

In 2019, Prem Kumar Gokuladasan - an engineer and MBA professional with 19 years of global experience - returned from Europe with one mission: to use technology to solve the single biggest barrier holding back rural Tamil Nadu children: the absence of quality, accessible education.

Kalvi40 was born from the simple belief that every child - regardless of where they are born - deserves access to learning that prepares them for life.
