Solinas Integrity Raises $5.5 Million in Series A1 Led by Hero Enterprise and Mela Ventures
Solinas Integrity raises $5.5 million in Series A1 funding led by Hero Enterprise and Mela Ventures to scale robotics and AI for water infrastructure.
Solinas Integrity has secured $5.5 million in Series A1 funding, marking a significant milestone for the IIT Madras-incubated deep-tech company working to transform the way cities inspect, clean and manage underground water and wastewater infrastructure. The round was led by Hero Enterprise Partner Ventures and Mela Ventures, with participation from the Luthra Group and existing investors including SBI Ventures, Rainmatter and 8X Ventures Fund I.
Solinas Scaling
For a company operating in an area that is rarely visible to the public, the significance of Solinas Integrity’s work is hard to overlook. Beneath every growing city lies an enormous network of pipelines, drains, sewers and wastewater assets that require constant inspection and maintenance. Solinas is bringing robotics, artificial intelligence and digital asset management into this largely manual ecosystem.
The fresh capital now gives the company an opportunity to take that technology to more cities, expand internationally and build the next generation of robotic inspection and cleaning solutions. With its sights set on India, the Middle East, Southeast Asia and eventually adjacent sectors such as oil and gas and defence, Solinas is positioning itself as more than a sanitation technology company.
Solinas Integrity Raises $5.5 Million in Series A1
Founded by IIT Madras alumni Divanshu Kumar and Moinak Banerjee, Solinas Integrity has spent years developing technology for one of the most difficult areas of urban infrastructure: underground water and wastewater networks. The company has now raised approximately ₹48 crore through its Series A1 round, giving it fresh momentum at an important stage of expansion.
The funding comes after an earlier investment round led by SBI Ventures in 2024, which also included Rainmatter. Solinas has gradually built its position by developing solutions that combine robotics and artificial intelligence rather than relying only on conventional infrastructure maintenance methods.
Its technology is currently deployed across more than 35 cities and 15 states in India, while the company has also begun expanding its presence in the Middle East. This existing footprint is important because it shows that Solinas is moving beyond the prototype stage and into real-world deployment.
The Vision Behind Solinas Integrity
The story of Solinas Integrity began in 2018 with a straightforward but ambitious objective: use technology to solve persistent problems in water management and sanitation. Instead of treating underground infrastructure as an unavoidable maintenance burden, the company began looking at it as an opportunity for innovation.
Its approach combines robotics, AI and data to make infrastructure inspection more accurate and less dependent on hazardous manual processes. Solinas has developed technologies designed to identify defects, leakages, blockages and other problems inside underground networks. Its work also focuses on reducing manual scavenging by mechanising difficult cleaning operations.
That mission gives the company a wider significance than a conventional robotics startup. Water loss, ageing pipelines and unsafe sanitation practices affect public health, urban efficiency and environmental sustainability. By bringing technology into these areas, Solinas is attempting to solve an infrastructure problem while also addressing worker safety and resource conservation.
How Solinas Integrity Uses Robotics
At the heart of Solinas Integrity’s business is its combination of robotic hardware and AI-powered software. One of its major technologies, Endobot, is designed to travel inside underground pipelines to inspect their condition and detect potential defects. The company has also developed platforms such as Swasth AI and HomoSEP as part of its broader technology portfolio.
The technology can provide operators with information about what is happening inside infrastructure that would otherwise be difficult, expensive or dangerous to inspect manually. Cameras, sensors and AI-based analysis can help utilities identify problems and prioritise maintenance.
This shift from reactive maintenance to technology-assisted inspection could become increasingly important as cities grow. Rather than waiting for a major leakage, blockage or infrastructure failure, authorities can use data and robotic inspection to understand the condition of underground assets and make more informed decisions.
Solinas Integrity Funding Opens New Markets
The new Solinas Integrity funding is expected to support expansion across India as well as international markets. The company plans to reach more states and municipal corporations while strengthening its presence in the Middle East and Southeast Asia.
This expansion is significant because the challenges Solinas addresses are not limited to Indian cities. Water leakage, ageing pipelines, wastewater management and underground infrastructure maintenance are global issues. Cities everywhere need better ways to inspect and maintain assets that are difficult to access.
The company also plans to invest in advanced robotic inspection and cleaning technologies, alongside improvements to its AI-powered software and asset management platforms. This combination could allow Solinas to create a more integrated infrastructure-management ecosystem rather than offering isolated robotic machines.
Hero Enterprise and Mela Ventures Back Deep Tech like Solinas
The participation of Hero Enterprise Partner Ventures and Mela Ventures highlights growing investor interest in Indian deep-tech companies solving fundamental infrastructure problems. Unlike software businesses that can often scale rapidly through digital distribution, robotics companies require engineering, manufacturing, field deployment and long-term customer adoption.
Hero Enterprise Chairman Sunil Kant Munjal said Solinas had taken on the difficult challenge of underground water and wastewater networks and approached it through robotics, linking the company’s work to water security, worker safety and urban resilience. Mela Ventures Managing Partner Krishnakumar Natarajan similarly highlighted the limitations of existing manual approaches and Solinas’ vertically integrated robotics platform.
For Solinas, the backing therefore represents more than additional capital. It signals investor confidence in a business model built around technology, infrastructure and measurable real-world impact.
Solinas Integrity Targets Water Infrastructure
Solinas Integrity is targeting ₹100 crore in revenue by FY28, with growth expected across its water, sanitation and industrial asset-management businesses.
Reaching that target will require the company to scale both its technology and its commercial operations. Municipal corporations and infrastructure operators often work within complex procurement systems, making deployment different from selling conventional consumer technology.
Yet Solinas’ existing presence across more than 35 cities and 15 states provides a foundation for further expansion. Its experience in working with real infrastructure networks can also help the company refine its products for different operating conditions.
The next phase will be about turning successful deployments into a repeatable model. If Solinas can demonstrate that robotic inspection reduces maintenance costs, improves safety and helps cities protect water resources, the potential market could extend well beyond its current operations.
The Road Ahead for Solinas Integrity
Solinas is not stopping at water and sanitation. The company has indicated plans to explore adjacent industries, particularly oil and gas and defence, where inspection of critical and often inaccessible infrastructure can require specialised technology.
The move could significantly broaden its addressable market. The underlying principle remains similar: use robotics and intelligent systems to inspect environments that may be difficult or dangerous for humans to access.
At the same time, the company will continue strengthening its core water infrastructure business. Its expansion into the Middle East and Southeast Asia could provide new opportunities in regions where urbanisation and infrastructure development are creating strong demand for smarter maintenance systems.
The challenge will be balancing expansion with product reliability, operational efficiency and customer adoption. Deep-tech businesses often require patience, but successful deployments can create strong long-term advantages.
What Solinas Integrity’s Growth Means
The rise of Solinas Integrity reflects a broader change in India’s technology ecosystem. Deep-tech innovation is increasingly moving beyond laboratories and research institutions into areas where technology can solve physical, large-scale problems.
Water infrastructure is a particularly important example. Cities cannot function efficiently without reliable water and wastewater systems, yet much of this infrastructure remains hidden underground and difficult to monitor. Solinas is attempting to make that invisible infrastructure more measurable, accessible and manageable through robotics and AI.
The company’s journey also demonstrates the importance of building technology around a genuine operational problem. Its solutions were not created simply because robotics and AI are fashionable technologies. They emerged from the need to inspect pipelines, detect failures, improve sanitation and reduce hazardous manual work.
That practical focus may ultimately become one of Solinas Integrity’s strongest advantages as it enters its next phase of growth.
Lessons from Solinas Integrity’s Journey
The Solinas Integrity story offers several lessons for India’s growing deep-tech ecosystem. First, solving a difficult real-world problem can create opportunities that extend far beyond a single market. Second, advanced technology becomes more valuable when it is connected to measurable outcomes such as water conservation, worker safety and infrastructure resilience.
Third, deep-tech companies need both technological expertise and commercial patience. Solinas has spent years developing its products, testing them in real environments and expanding city by city. Its latest funding round suggests that investors now see the potential to take that model to a much larger scale.
Most importantly, Solinas Integrity’s $5.5 million Series A1 funding represents a growing belief that India’s next generation of technology companies can address some of the country’s hardest infrastructure challenges. From underground pipelines to industrial assets, the company is building technology for places where humans cannot easily see, reach or work safely.
As Solinas moves toward its ₹100 crore FY28 revenue ambition and expands across India and international markets, its journey will be closely watched. The company’s success could demonstrate that Indian deep-tech startups can combine commercial growth with meaningful infrastructure and social impact.
