Sedemac: From IIT Bombay innovation to IPO success and automotive breakthroughs

Sedemac Mechatronics, anchored by TVS Motor and other Indian OEMs, has grown from a university project to an IPO-scale company. The company achieved this by developing unique control algorithms, using frugal hardware, and relying on debt-led growth. Its technology now powers millions of two- and three-wheelers and is expanding into commercial vehicles.

Key Highlights

• Sedemac grew from an IIT Bombay project to an IPO-scale company with TVS Motor as an anchor customer
• Revenue tripled from Rs 200 crore to Rs 650 crore between 2018 and 2024, funded by debt
• IPO raised Rs 1,087.45 crore, with shares debuting at a 13.5 percent premium on NSE
• Sedemac holds 35 percent of the domestic ISG ECU market for two- and three-wheelers
• The company is expanding into commercial vehicle emission control modules and international markets

Origins and Early Innovations

Sedemac’s story began in 2004 at IIT Bombay. Amit Dixit, a master's student, met Prof. Shashikanth Suryanarayanan, a new faculty member with a PhD from the University of California, Berkeley. Along with Manish Sharma and Pushkaraj Panse, they worked on industry-sponsored projects. These included a steer-by-wire vehicle for Sona Koyo Steering Systems and an electronic fuel injection ECU for TVS Motor Company. The combined project budgets were between Rs 30 and 50 lakh.

The team’s prototypes functioned as intended, surprising industry veterans who were used to importing such technology. In 2007–2008, Sedemac was incorporated, with Suryanarayanan, Dixit, and Sharma as the core founders. Early investment came from Naren Gupta of Nexus Venture Partners, who acquired 26% equity for Rs 2 crore. The founders soon realized they could not compete directly with established global players like Bosch and Astemo. Instead, they focused on genuine innovation.

Breakthroughs and Market Expansion

In 2013, Dixit proposed a new method for ignition timing control in carbureted two-wheelers. Traditionally, this required two sensors. Sedemac’s approach eliminated one sensor by using algorithms to estimate engine load from the crank signal. This innovation reduced costs and improved performance, gaining acceptance from OEMs such as TVS Motor.

Sedemac initially licensed its software to run on existing vendor hardware, generating revenue with each vehicle sold. TVS Motor became the anchor customer, supporting Sedemac’s entry into the market. The company’s financial strategy was unconventional. From December 2018 to July 2024, Sedemac did not raise fresh equity. Revenue grew from Rs 200 crore to Rs 650 crore, funded by debt.

IPO and Future Directions

Sedemac’s IPO opened on March 4 and closed on March 6, 2024. The offering comprised 8,043,300 shares, raising ₹1,087.45 crore through an offer for sale. The issue was subscribed to 2.68 times, with institutional buyers oversubscribing their quota 8.46 times. Shares debuted on the NSE at ₹1,535, a 13.5% premium over the issue price of ₹1,352, even as the broader market declined.

Today, Sedemac holds about 35% of the domestic market for ISG ECUs in two- and three-wheelers. Clients include TVS Motor, Hero MotoCorp, Mahindra, Tata Motors, Kirloskar, and Ashok Leyland. The company is expanding internationally, with early revenues from the US and Europe and patents filed in Japan and China. Notable investors include Nandan Nilekani, N.R. Narayana Murthy, and N.S. Parthasarathy.

Sedemac is now developing Aftertreatment Control Modules (ACMs) for heavy-duty commercial vehicles. These systems manage emissions and ensure compliance with standards like India’s BS-VI. The company’s ACM for an Indian CV maker is under validation for series production, marking a new phase in Sedemac’s growth.

Conclusion

Sedemac’s rise from an IIT Bombay laboratory to an Rs 1,087 crore IPO underscores how research-led deep tech can outpace legacy global suppliers in critical automotive electronics. By scaling intelligent control solutions for ICE, hybrids, and EVs, the company not only strengthens India’s auto-ancillary ecosystem but also sets a compelling template for future faculty-led innovation.
