“You have to be crazy to want to make silicon” | Sharan Srinivas J, Mindgrove

Episode Summary

This episode is a must-watch for anyone who uses a mobile phone or has ever made a QR payment. If you have ever wondered about all the little and big parts that go into your phone or tablet, this episode will be a treasure trove of information and facts. 

Watch Amrut speak with Sharan, the co-founder and CTO of Mindgrove Technologies as well as a Research scholar at IIT Madras, about topics from their foray into the semiconductor industry to balancing academic life and work life, Sharan’s views about India’s Semiconductor Mission and how it feels to be a startup with your seed investors coming back to invest in you for the second round and be a part of the DLI scheme by the Government of India.

From explaining how a 12-inch silicon wafer transforms into the powerful chips powering your smartphone to demystifying terms like "fabless," "nanometer nodes," and "SoC," Sharan breaks down the complex semiconductor ecosystem with remarkable clarity. Learn why countries worldwide are investing billions in chip technology, how a single dust particle can destroy an entire chip, and why the machine that creates advanced chips costs a staggering 2,400 crores per unit and requires multiple Boeing 747s just to transport!

If you ever thought that this technology is far away from your daily life, watch as Sharan lists all how this technology plays a starring role in your life on a daily basis.

Amrut’s Comment

“Sharan, the CTO at Mindgrove Technologies has that one quality that almost all South Indian entrepreneurs share - they don't like to make any noise and want their work to do all the talking. But when Sharan gets into a talking mood, he shares the best stories ever. And, explains stuff really well. 

I’ve been listening to him every week for quite some time now as part of the work CoreVoice does for Mindgrove. Once their Series A was completed, I managed to convince him to sit down for a recorded conversation for the Best Place to Build Podcast, and I’m so glad that I can share this with you.”
