The round comes about 19 months after Peppermint raised Rs 34 crore (about $4 million) in a Series A round in April 2025. That round was backed by Indian Angel Network, JDSS, Enrission India Capital and Vinners, and took the startup’s total funding to Rs 49 crore at the time.
Its earlier backers include NKK Group, Venture Catalysts, Voxtur Ventures and SINE, the IIT Bombay incubator where the startup started.
What Peppermint builds
Founded in 2019 by Runal Dahiwade, Peppermint designs and builds autonomous robots for commercial floor cleaning and material transportation.
The startup’s robots work in factories, hospitals, airports, malls, warehouses, hotels and universities. The company mainly sells to facility management companies, which run cleaning operations for their clients and choose the equipment, chemicals and processes used.
Peppermint’s current range includes the SD45 and SD20 floor scrubbers, the VC20 industrial vacuum, the MOP20 mopping robot, the SD20 CR cleanroom scrubber and an autonomous mobile robot for moving materials.
The startup develops its hardware, software and perception systems in-house and assembles its robots in Pune. The robots run on its proprietary Peppermint OS and use computer vision and LiDAR to map spaces, plan cleaning routes and avoid obstacles, while a cloud dashboard lets customers monitor them in real time. For sites with strict information security rules, it also offers robots that run fully offline.
Peppermint said its cleanroom robots have passed qualification testing in an EU GMP Grade cleanroom at a global pharmaceutical company. Cleanrooms used in drug manufacturing are among the most tightly regulated environments a cleaning machine can work in.
“Cleaning teams keep hospitals, factories and airports running. Our robots work alongside them and take on the most repetitive, physically demanding jobs, like floor scrubbing and material transportation,” Dahiwade said.
“Our customers judge us on one thing: a clean floor, every shift. So we build our robots heavy-duty, to last multiple years, and we stay with every machine for its whole lifecycle. This round lets us build more of them, closer to our customers worldwide,” he added.
Peppermint now operates in nine countries across Asia, North America and Europe, up from six at the time of its Series A. It entered the US in 2024, and the US has since become its largest market.
Where the money will go
Peppermint plans to use the primary capital in five areas. It will spend on research and engineering for new robots, and on production infrastructure, tooling and capacity.
It also plans to set up an assembly line in North America over the coming months, alongside its Pune facility, to bring production, service and customer support closer to US customers. The rest will go towards business development in the US and Asia, a bigger presence in Europe, and hiring senior leaders and engineers.
The startup said it will expand its range of autonomous floor-cleaning and material-handling robots and continue work on its next-generation CR line of cleanroom robots.
