Solinas Integrity, an IIT Madras-incubated climate deep-tech and robotics company, today announced a USD 5.5 million Series A1 funding round led by Hero Enterprise Partner Ventures and co-led by Mela Ventures, with participation from Luthra Group. Existing investor SBI Ventures, through the SVL-SME Fund, doubled down on its position, alongside continued backing from Rainmatter and 8X Ventures Fund I. The round follows Solinas's Series A, led by SBI Ventures through the SVL-SME Fund (Neev II) in May 2024, and underscores the deepening alignment between India's climate-tech innovation ecosystem and global sustainability-focused capital.

Founded by Divanshu Kumar and Moinak Banerjee, Solinas builds robotics and AI systems that inspect, clean, and digitize underground water and wastewater infrastructure, solving problems of water leakages, contamination & elimination of manual scavenging . Its technology is deployed across 35+ cities and 15+ states in India, with expanding operations in the Middle East, helping utilities run safer, smarter 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.

Solinas will use the fresh capital to scale aggressively — deepening penetration in existing markets while expanding into new states and municipal corporations across India, and building out its international footprint with a strategic focus on the Middle East and Southeast Asia. The company will also accelerate development of next-generation robotic inspection and cleaning technologies, strengthen its AI-powered software and asset management platforms, and expand its industrial solutions portfolio — positioning Solinas as India's first end-to-end value creator for underground infrastructure, engineered to global technology standards. Solinas is targeting Rs. 100 crore in revenue by FY28, driven by growth in its core water and sanitation business alongside continued momentum in industrial asset management.

Commenting on the fundraise, Sunil Kant Munjal (Chairman, Hero Enterprise), “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.”

Commenting on the fundraise, Krishnakumar Natarajan (Managing Partner, Mela Ventures): 
“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,“ — Krishnakumar Natarajan, Managing Partner, Mela Ventures.

Commenting on the fundraise, 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 Exclusive Financial Advisor to the transaction.
