Solinas Integrity Raises USD 5.5 Million to Scale AI Robotics for Water Infrastructure

Founded by Divanshu Kumar and Moinak Banerjee, Solinas develops robotics and artificial intelligence systems for inspecting, cleaning and digitizing underground water and wastewater infrastructure. The company's technology addresses water leakages, contamination and the elimination of manual scavenging. Its solutions are deployed across more than 35 cities and 15 states in India, while its operations continue to expand in the Middle East to help utilities manage safer and smarter underground networks.

"Solinas has come this far by proving that the technology & the model works, city after city, contract after contract, at a sizable scale. As we enter our next phase, we have the leadership team as well as the backing of mission aligned institutional investors in place to build India's largest tech company in the underground asset management space. From here, we're also planning to extend into adjacent, highstakes sectors — starting with Oil & Gas and Defence, where the same discipline around critical, unseen infrastructure applies," said Divanshu Kumar, Co-Founder and CEO of Solinas Integrity.

The company said the newly raised capital will be used to accelerate expansion across existing markets, enter additional states and municipal corporations in India, and strengthen its international presence with a strategic focus on the Middle East and Southeast Asia. The investment will also support the development of next-generation robotic inspection and cleaning technologies, enhance AI-powered software and digital asset management platforms, and expand Solinas' industrial solutions portfolio. The company aims to achieve revenue of Rs. 100 crore by FY28 through growth in its core water and sanitation business alongside continued expansion in industrial asset management.

Commenting on the investment, Sunil Kant Munjal, Chairman of Hero Enterprise, said, "At Hero Enterprise, we have long believed that India's most consequential infrastructure challenges will be solved not by incremental fixes, but by bold, technology-first thinking. Solinas Integrity embodies exactly that conviction, a team that has taken the hardest problem in urban infrastructure, underground water and wastewater networks, and reimagined it from the ground up with robotics. Their work directly addresses water security, worker safety, and the long-term resilience of our cities. This investment reflects our commitment to backing entrepreneurs who are building for India's future with both scale and purpose."

Krishnakumar Natarajan, Managing Partner at Mela Ventures, said, "Current methods of maintaining India's water infrastructure are manual, hazardous, time-consuming, and costly, with virtually no visibility into what lies beneath. Solinas is changing that through a vertically integrated robotics platform that maps underground infrastructure, diagnoses issues, and delivers end-to-end solutions. At Mela Ventures, we have followed Divanshu and the team's journey for four years, and their growth has been remarkable. Backing fearless founders solving globally hard problems from India is core to our investment philosophy, and Solinas is one of the best examples of that."

Akshay Panth, CIO, Neev Funds, SBI Ventures Limited, said, "Solinas Integrity has done what few deep-tech companies manage - translating genuine engineering innovation into repeatable commercial traction at the exact intersection of water security, worker safety, and climate resilience. This follow-on reflects Neev's conviction that technology-led transformation in underserved infrastructure sectors is where India's next decade of impact will be built."

Kumbhat Advisors, led by Akash Sethia, served as the Exclusive Financial Advisor for the transaction.

Founded by Divanshu Kumar and Moinak Banerjee and incubated at IIT Madras, Solinas Integrity focuses on transforming urban water and wastewater infrastructure management through proprietary robotics, AI-powered analytics and digital asset management solutions. The company enables utilities and municipalities to inspect, clean, digitize and manage underground networks more efficiently. Solinas has also expanded its robotics and AI capabilities into the industrial sector, where it works with leading automotive, pharmaceutical and manufacturing companies for asset inspection and management. Its innovations, including robotic inspection platforms and the Manhole Cleaning Robot, are designed to support safer, smarter and more sustainable sanitation operations.

Recognized and honoured by Prime Minister Narendra Modi, Solinas' solutions have been deployed across more than 35 cities and 15 states in India. The company has worked with Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB), Bangalore Water Supply and Sewerage Board (BWSSB), Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB), Sangli, Miraj Municipal Corporation, Chhatrapati Sambhajinagar Municipal Corporation, Tripura Jal Board, Greater Chennai Corporation and Noida Authority.
