IIT Bombay-incubated SEDEMAC Mechatronics dominates India's ISG ECU market
There is a company in India called SEDEMAC Mechatronics that started at IIT Bombay in 2007.
It makes the small computer brain inside motorcycles and scooters that helps them start smoothly.
Normally, bikes use a small sensor to know where the engine is, but that sensor can break from heat, dust, and vibration.
This company invented special software that figures out the engine position without that sensor.
Because of this, their product is more reliable and cheaper to make.
Today, this company makes more than 8 out of every 10 new starting systems for two- and three-wheelers in India.
Its profits grew a lot last year, and its revenue crossed ₹1,000 crore for the first time.
Now it wants to use the same idea for electric vehicles, power tools, and generators.
Many investors have bought its shares, and the price has gone up a lot.
Some people worry the shares are now too expensive, but the company hopes to keep growing.
SEDEMAC Mechatronics, incubated at IIT Bombay in 2007, holds over 80% of the incremental ISG ECU market in India's two- and three-wheelers.
Its patented sensorless control algorithms replace physical sensors by estimating piston position from engine electrical signals.
In FY26, revenue crossed ₹1,000 crore for the first time, growing 61% year-on-year, with ROCE expanding above 40%.
The company is expanding into EV motor control units, generator controllers, commercial vehicle electronics, and power tools.
Shares have rallied over 100% since the March 2026 IPO to a high of ₹2,978, pushing the trailing PE ratio above 100X.

Bull case: Moats and growth
Bear case: Valuation risk
Valuation
Bull case: Moats and growth
The premium is justified by a 40% ROCE, dominant market share, and software-like economics.
Bear case: Valuation risk
A trailing PE above 100X with a limited listed history leaves little margin for error.
Growth expansion
Bull case: Moats and growth
New segments such as EV motor controllers, power tools, and generators offer a large addressable market runway.
Bear case: Valuation risk
Newer businesses will compete against well-established global Tier-1 suppliers with far larger scale and R&D capabilities.
Near-term headwinds
Bull case: Moats and growth
Strong volume-led growth should continue in FY27 despite cost pressures.
Bear case: Valuation risk
Higher semiconductor prices and commodity costs could put mild pressure on margins.
