From an IIT Bombay Lab to a ₹1,000 Crore IPO | The SEDEMAC Deep-Tech Story

What does it take to build original deep tech in India, get some of the country’s largest companies to adopt it, and eventually take the business to a ₹1,000+ crore IPO?

In 2007, Professor Shashikanth Suryanarayanan started ‪@SEDEMAC-Official‬  Mechatronics out of an IIT Bombay lab. Nearly two decades later, SEDEMAC has become one of India’s standout deep-tech success stories. The company crossed ₹1,000 crore in annual revenue, ships around 1 million motor controllers every quarter, and its ISG (Integrated Starter Generator) technology is now on an estimated 12 to 13 million vehicles on the road.

It also reached a milestone very few Indian deep-tech companies do: the public markets, through a ₹1,087 crore IPO that was entirely an Offer for Sale, with no fresh capital raised by the company.

In this episode of the Prime Venture Partners Podcast, Jerome Manuel sits down with Shashikanth to explore how SEDEMAC went from building proprietary control technologies to creating products adopted by major two-wheeler and generator manufacturers.

Shashikanth explains SEDEMAC’s work in sensorless commutation and Integrated Starter Generators, but the bigger story is how a technology moves from an engineering breakthrough to something millions of people actually use. SEDEMAC had to demonstrate something customers were not asking for, convince large OEMs to test it, validate it over years, and gradually earn adoption across multiple vehicle models.

That leads to one of the central ideas of the conversation: technology creators do not always enter existing markets. Sometimes they create the market itself.

Finally, Shashikanth breaks down SEDEMAC’s growth from ₹36 crore in revenue in 2016 to ₹1,058 crore in FY26, and makes a provocative argument: if a technology company has genuinely created something differentiated and reached scale, that advantage should eventually show up in pricing power, profitability and capital efficiency.

A rare look at what it takes to turn deep-tech innovation into a scaled business in India.
