Peppermint Robotics Raises Rs 100 Cr to Scale Cleaning Robots Globally

Peppermint Robotics has raised Rs 100 crore — roughly $10.5 million — in a pre-Series B round led by pi Ventures and Crane Venture Partners, with Asiana Fund also participating. The round combines fresh capital with secondary share transactions, the company said.

The money arrives on the heels of steep growth. Peppermint said it doubled its revenue last year and grew nearly sixfold between FY24 and FY26. Its previous raise was Rs 34 crore ($4 million) in a Series A in April 2025. That's roughly tripled funding in under a year — a pace that signals investors want to push hard while the growth curve is steep.

What does Peppermint actually build?

Founded in 2019 at the Society for Innovation and Entrepreneurship at IIT Bombay, the Pune- and Austin-based startup makes autonomous cleaning robots. Its machines scrub floors and move materials across factories, hospitals, airports, malls, warehouses, hotels and universities — nine countries in total, with the US as its biggest market.

The design philosophy matters for buyers. The robots are built to fit into existing routines rather than disrupt workflows, and the company primarily serves facility management companies that oversee cleaning operations, including equipment, chemical and process selection.

Everything is in-house: hardware, software and perception systems, with assembly in Pune. The robots run on proprietary Peppermint OS, using computer vision and LiDAR to map spaces, plan routes and avoid obstacles. Operators monitor fleets in real time through a cloud dashboard. For security-sensitive sites, Peppermint offers fully offline 'stealth' robots that meet stringent information security requirements.

The cleanroom breakthrough

The company's most demanding deployment is at a global pharmaceutical company. Peppermint said its cleanroom robots have passed qualification testing in an EU GMP Grade cleanroom — among the most tightly regulated settings a cleaning robot can enter. Cleanroom robots are specialised manipulators engineered to operate in controlled, contamination-free environments.

That qualification is the real news buried in this funding announcement. Passing EU GMP testing opens a regulated pharma market that most robotics vendors can't touch, and it's the wedge Crane Venture Partners is backing.

What the founders and investors said

Runal Dahiwade, Founder and CEO of Peppermint Robotics, was direct about the business. "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," he said.

"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," Dahiwade added.

The investors lined up behind specific theses. 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.

Where the Rs 100 crore goes

The capital has a clear allocation plan:

• Next-generation robotics development and expanded manufacturing capacity
• A North America assembly line planned over the coming months
• Stepped-up business development in the US and Asia, and growth in Europe
• Senior leadership and engineering hires
• A wider range of floor-cleaning and material-handling robots, plus development of the cleanroom line

What does this change for the industry?

For facility management operators, a US-based assembly line means shorter delivery cycles and local support for a vendor that until now built everything in Pune. For competitors in commercial cleaning robotics, the cleanroom qualification plus a sixfold revenue run raises the bar on regulated-environment deployments. For Peppermint, the test is whether it can convert a validated product and fresh capital into durable share across three continents at once.
