Peppermint Robotics bags Rs 100 Cr in pre-Series B funding round

Peppermint Robotics, which makes autonomous cleaning robots, has raised Rs 100 crore (about $10.5 million) in a pre-Series B round led by pi Ventures and Crane Venture Partners. Asiana Fund also participated in the round.

The round involved fresh capital and secondary share transactions.

The money arrives on the back of rapid growth by Peppermint.

The Pune- and Austin-based startup said it doubled its revenue last year and grew nearly sixfold between FY24 and FY26. It last raised Rs 34 crore ($4 million) in a Series A round in April 2025. Peppermint has a presence in nine countries, with the US being its biggest market.

Founded in 2019 at the Society for Innovation and Entrepreneurship at IIT Bombay, the company's autonomous cleaning robots are deployed across a range of commercial and industrial environments, including factories, hospitals, airports, malls, warehouses, hotels and universities. Its machines scrub floors and move materials in factories, hospitals, airports, malls, warehouses, hotels and universities. They are designed to fit into existing routines rather than disrupt workflows.

The company primarily serves facility management companies that oversee cleaning operations, including the selection of equipment, chemicals and cleaning processes.

One of its more challenging deployments is at a global pharmaceutical company, where its cleanroom robots have passed qualification testing in an EU GMP Grade cleanroom, among the most tightly regulated settings a cleaning robot can enter, Peppermint said, in a statement.

Cleanroom robots are specialised manipulators engineered to operate in controlled, contamination-free environments.

The startup builds its hardware, software and perception systems in-house and assembles its robots in Pune. They run on proprietary Peppermint OS, using computer vision and LiDAR to map spaces, plan routes, and avoid obstacles. Operators can monitor them in real time through a cloud dashboard. For security-sensitive sites, the company offers fully offline 'stealth' robots that meet stringent information securtiy requirements.

Runal Dahiwade, Founder and CEO of Peppermint Robotics, said, "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. 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."

The newly raised capital will go towards next-generation robotics and expanding manufacturing capacity. An assembly line in North America is also being planned over the coming months.

Peppermint also intends to step up business development in the United States and Asia, grow its presence in Europe, and hire senior leaders and engineers.

On the product side, it plans to widen its range of floor-cleaning and material-handling robots and develop its cleanroom line.

Investors are optimistic about Peppermint's potential and promise.

Shubham Sandeep, Partner at pi Ventures, pointed to the company's "clear ROI" in demanding settings such as healthcare and hospitality. Anandamoy Roychowdhary of Crane Venture Partners said Peppermint has built a production-grade cleanroom robot for mission-critical businesses. Neha Aggarwal of Asiana Fund called the company the kind of advanced manufacturing business India can build for global markets.
