IITM-incubated deeptech startup Solinas Integrity raises $5.5M

IIT Madras-incubated climate deeptech and robotics startup Solinas Integrity has raised $5.5 million in a Series A1 funding round led by Hero Enterprise Partner Ventures and Mela Ventures. The round also saw participation from Luthra Group.

Existing investor SBI Ventures doubled down on its position, alongside continued backing from Rainmatter and 8X Ventures Fund I, the company said in a statement.

The round follows Solinas's Series A round, which was 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 digitise underground water and wastewater infrastructure, solving the problems of water leakage, contamination, and manual scavenging.

The Chennai-based startup will use the capital to scale, deepen its penetration in existing markets and expand into new states and municipal corporations across India. It will also use the funds to build out its international footprint with a strategic focus on the Middle East and Southeast Asia.

Solinas is targeting Rs 100 crore in revenue by FY28, driven by growth in its core water and sanitation business alongside industrial asset management.

“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 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.

Kumbhat Advisors served as the financial advisor to the transaction.

Sunil Kant Munjal, Chairman, Hero Enterprise, said, “Solinas Integrity 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."
