How SEDEMAC Is Revolutionizing India's Auto Industry

Founded in 2007 by Shashikanth Suryanarayanan, SEDEMAC was built to fill a major gap in the automotive component manufacturing industry, where most parts had to be imported. The goal was clear: to develop advanced electronic control units (ECUs), motor controllers, and powertrain solutions specifically for Indian automakers. However, back then, deeptech was a hard sell. Investors were skeptical about complex engineering-led businesses, and deeptech funding barely made a dent in the overall investment landscape.

Despite these early challenges, SEDEMAC's tech became an indigenous solution for the automotive industry, offering real-time decision-making for machines like engines, motors, and power generators. Fast forward 19 years, and SEDEMAC's IPO has proven that patience and persistence in deeptech can pay off.

Unlike companies that solely rely on hardware or software, SEDEMAC brings a perfect blend of machine intelligence to the table. Their tech doesn't just control engines—it decides how systems should respond in real-time. The company's solutions focus on autonomous systems and integrate sensor data to enhance product performance, making it an irreplaceable partner for OEMs like TVS, Bajaj Auto, and Hero MotoCorp.

SEDEMAC's advantage lies in working closely with OEMs to deeply integrate its proprietary technologies, making it difficult for competitors, including global players like Bosch and Continental, to replace them without a complete platform overhaul.

In a sector that typically sees low margins, SEDEMAC has managed to achieve impressive profitability with a 20% EBITDA margin in FY26. Their focus on high-volume embedded systems used in two-wheelers and three-wheelers has paid off handsomely, growing revenue from ₹540 Cr in FY24 to ₹640 Cr in FY25, and approaching ₹770 Cr in FY26.

However, SEDEMAC's revenue profile is concentrated, with 75–80% coming from a few key customers. While this approach has led to rapid growth, it also means that the company's future is tied to a limited number of customers in the two-wheeler and three-wheeler segments.

Unlike most startups that go public to raise capital, SEDEMAC's IPO was an offer-for-sale allowing early investors to exit with substantial returns. Key investors, like A91 Partners and Nandan Nilekani's family office, cashed in on the IPO, further cementing SEDEMAC's place as a leader in the deeptech space.

The company's market cap now stands at ₹6,798 Cr, signaling the potential of deeptech companies to deliver substantial returns, challenging the narrative that such firms can't build commercial success.

While SEDEMAC's expertise in control systems has made it indispensable in internal combustion engines, the shift to electric vehicles (EVs) presents new challenges and opportunities. The EV revolution will introduce new technologies, competitors, and dynamics. SEDEMAC must adapt its IP-driven approach to meet the evolving demands of the electric mobility space.

The company is also venturing into adjacent sectors like industrial applications and power tools, expanding its expertise to other areas of control systems.

With nearly two decades of experience in deeptech, SEDEMAC must stay at the cutting edge of innovation. The real question now is: Can it replicate its success in the fast-evolving EV and industrial sectors?

As SEDEMAC steps into its next phase as a listed company, it will need to balance its strong relationships with OEMs and continuous tech iterations to thrive in an increasingly competitive landscape. The stakes are high, but with its proven track record, the company is poised to lead the way in India's growing automotive tech ecosystem.
