Industry 5.0 startup Venttup has raised $3 million in a Pre-Series A round led by Rainmatter by Zerodha and Unicorn India Ventures.

The funds will be used to expand the engineering team, invest in a precision manufacturing facility and rapid prototyping infrastructure, and adopt AI to improve B2B sourcing, supplier intelligence and operational efficiency.

The funding will support Venttup’s scale-up journey as it moves from engineering development to scalable production for the energy transition, defence, aerospace and space sectors.

Sandeep Nair, Co-founder and CEO, Venttup, said, “India’s next phase of manufacturing growth requires strong engineering capabilities that can translate complex requirements into validated, production-ready components. At Venttup, we are building an engineering-first manufacturing company that brings together design standardisation, rapid prototyping, testing and scalable production through India’s capable MSME ecosystem.

“This funding round will help us strengthen our team, expand precision manufacturing capabilities and adopt technology to serve both emerging deep-tech companies and established OEMs. Our ambition is to build resilient supply chains for critical sectors while advancing our mission of ‘India for India, India for the World’—developing indigenous capabilities for domestic needs and making India a trusted source of high-value manufacturing for global markets.”

Venttup is also setting up a manufacturing facility in Bengaluru to strengthen its rapid prototyping and precision manufacturing capabilities. The facility will support precision machining, turning and sheet metal production for applications in the energy transition, defence, aerospace and space sectors. It will enable a faster move from component development and validation to production readiness and mass manufacturing.

Abhinav Singh Negi, Lead – Climate and Deeptech, Rainmatter by Zerodha, said, “When we spoke to our existing portfolio companies about their execution challenges, we consistently realised how difficult it is for hardware startups to find reliable partners who can manage the transition from validation to production. At the same time, the push for indigenisation across critical sectors is unlocking a massive wave of industrial demand that simply didn’t exist before. Venttup is uniquely positioned to fulfil this demand by acting as a dependable operational bridge. Its approach of combining an in-house precision facility in Bengaluru with a vast, quality-checked network of local MSMEs provides immense value to the ecosystem. We are glad to support Sandeep and his team as they build this critical manufacturing infrastructure.”

Bhaskar Majumdar, Managing Partner, Unicorn India Ventures, said, “We have been invested in Venttup since the seed round and have seen the speed at which the company is growing. This prompted us to co-lead this round with Rainmatter, as we believe that, as a pure-play deep-tech investor, we are the right partners to help Venttup scale. Precision manufacturing as a segment is going to experience explosive growth as the deep-tech ecosystem matures. Whether the use case is defence or space, such companies will need a strong partner that can source precision equipment, speed up prototyping and provide a reliable supply chain. Venttup has already built for this and more.”

Venttup is expanding across four strategic business verticals: energy transition and data centres; aerospace, defence and space systems; smart infrastructure and future mobility; and electronics, automation and smart manufacturing. These verticals address India’s growing demand for indigenous engineering and manufacturing.

Across them, the company aims to become a long-term development and manufacturing partner for OEMs, technology companies and emerging deep-tech businesses, supporting domestic supply-chain resilience and global sourcing from India.

Venttup raised an undisclosed seed round in 2024. Since then, the company has grown fivefold to Rs 0.1 billion in FY2025–26, reflecting growing customer demand for its engineering-led localisation and manufacturing services.

Over the past 12 months, Venttup has added more than 15 blue-chip companies to its customer base and built a business opportunity pipeline of approximately Rs 0.3 billion across new energy, mobility and smart infrastructure. This traction reflects growing demand for domestic component development, localisation and dependable manufacturing execution.
