Robotics startup Solinas Integrity bags $5.5 million from Hero Enterprise, Mela Ventures

Robotics startup Solinas Integrity has raised $5.5 million (around Rs 48 crore) in a round led by Hero Enterprise Partner Ventures and Mela Ventures, with participation from the Luthra Group. Existing investors SBI Ventures (through the SVL-SME Fund), Rainmatter, and 8X Ventures Fund I also participated.

Founded by IIT Madras alumni Divanshu Kumar and Moinak Banerjee, Solinas develops robotics and artificial intelligence systems to inspect, clean, and digitise underground water and wastewater infrastructure. Its technology is currently deployed across more than 35 cities and 15 states in India; the company has also expanded to the Middle East.

"Solinas has come this far by proving that the technology and the model works, city after city, contract after contract, at a sizeable scale," said Kumar, who’s also the chief executive.


He added that the startup is looking to expand in adjacent sectors, starting with oil & gas and defence, where the same discipline around critical, unseen infrastructure applies.

The company will use the fresh capital to expand into more states and municipal corporations across India, while growing its presence in the Middle East and Southeast Asia. It will also invest in robotic inspection and cleaning technologies and improve its AI-powered software and asset management platforms.

Solinas said it is targeting revenues of Rs 100 crore by FY28, driven by growth in its water, sanitation, and industrial asset management businesses.

Sunil Kant Munjal, chairman, Hero Enterprise, said Solinas has taken the hardest problem in urban infrastructure — underground water and wastewater networks — and reimagined it from the ground up with robotics.

"Their work 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, 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."

The funding comes after Solinas' undisclosed round led by SBI Ventures in May 2024. The company also won The Economic Times Startup Awards 2022 in the Best on Campus category.
