Peppermint Robotics' $10.5M Pre-Series B Expands Production

Peppermint Robotics builds a service commitment into equipment that spends its working life getting dirty. The Pune- and Austin-based robot maker's planned North American assembly line brings manufacturing closer to its largest market, while its engineering and production base in India continues to grow.

The company announced an INR100 crore Pre-Series B transaction, approximately $10.5M, on November 4, 2026. pi Ventures and Crane Venture Partners led the round, with Asiana Fund participating; the transaction includes both new capital and secondary share sales. Its commercial significance lies in the work the primary investment is intended to support: building more robots, developing specialized machines and helping customers keep them operating.

For facility management buyers, the machine belongs inside a cleaning operation that already has people, equipment and obligations. Peppermint's expansion connects the engineering decision about what a robot can do with the operating decision about who will support it after installation. That connection becomes more consequential as an Indian manufacturing business serves customers across several continents.

What the Pre-Series B finances

Peppermint's announced transaction amount covers primary capital and secondary share transfers, with no published allocation between them. The approximately $10.5M figure therefore describes the package, rather than a verified amount of fresh money entering the business. The company previously announced an approximately $4M Series A in April 2025, but the new transaction should not be added mechanically to earlier rounds to calculate cumulative primary funding.

The primary proceeds are earmarked for engineering, production infrastructure, North American operations, international business development and hiring. An assembly line in North America is planned, while Pune remains central to manufacturing and research. Those priorities put physical capacity and customer support beside product development in the investment case.

Runal Dahiwade told PTI that the Pune operation has annual capacity of up to 1,500 robots and that Peppermint aims to reach at least 3,000 by the end of FY28. That is a manufacturing target, not a forecast of completed sales. Capacity gives the business room to supply demand; installations still create their own work in commissioning, maintenance and customer service.

How Peppermint chose its customer

Runal Dahiwade's account of the company's origins begins in automotive services, where repetitive work depended heavily on people. In a founder interview with CircuitDigest, he described exploring a car-washing robot before recognizing the broader commercial housekeeping opportunity. Public and industrial floors supply an unusually persistent assignment: they need cleaning again after yesterday's cleaning is finished.

Founded in 2019, Peppermint's historical founding team also included Miraj Vora and Nityanand Prabhutendolkar, as recorded in YourStory's company profile. The current official leadership page identifies Runal Dahiwade as founder and CEO and Harshal Deshpande as CTO. That leadership pairs responsibility for the customer relationship with ownership of the machines and software needed to sustain it.

Peppermint primarily sells into facility management companies that already select equipment, chemicals and cleaning processes. That buyer has to fit the machine into a functioning service, including the people who supervise it. As an operating interpretation, this helps explain why distribution, training and support belong in the same commercial conversation as navigation capability: the purchase changes an existing routine that someone remains responsible for delivering.

The technology has to fit a working facility

Peppermint's SD45 product page describes an autonomous scrubber-dryer using LiDAR and simultaneous localization and mapping, or SLAM, to navigate. Peppermint OS coordinates navigation and obstacle avoidance. The company develops the hardware, software and perception systems internally, giving its engineers responsibility for how those pieces work together at a customer site.

The engineering organization has also described a modular electronics platform that can support different robot types. In a June 2025 interview with Runal Dahiwade and Harshal Deshpande, Peppermint discussed remote diagnostics, monitoring and software updates alongside its hardware architecture. That design approach links the engineering team to machines already installed in facilities, where a diagnosis can determine how quickly useful work resumes.

For a buyer, those capabilities matter through ordinary operating questions: how the robot is configured for the site, how a fault is identified and how the team restores useful cleaning work. That is the commercial logic behind treating service as part of the product. Peppermint can own more of the engineering stack in-house, but the customer encounters the combined result on a floor shared with people and other equipment.

Why the assembly footprint matters

Peppermint says it now operates in 9 countries and that the US is its largest market. YourStory's November 4 reporting also records company-reported revenue growth of nearly 6x between FY24 and FY26. Those are company claims about traction, useful for understanding the expansion priorities without treating them as audited financial disclosure.

The proposed North American assembly line follows customers who are already buying. Locating more work near them could improve the manufacturer's ability to coordinate production and support, although the announcement provides no verified completion date or measured benefit from a line that is still planned. Pune's expansion and the North American project are connected parts of a geographically distributed operating business.

For pi Ventures and Crane Venture Partners, the transaction puts capital behind both the engineering organization and the practical infrastructure around the machines it supplies. Peppermint's planned next cleanroom robotics line would extend that responsibility in a specialized setting. As production expands, each installation leaves a cleaning team with a machine to operate and a manufacturer it expects to keep within reach. The assembly plan brings that ongoing relationship closer to the market already accounting for the largest share of Peppermint's business.
