Bengaluru-based manufacturing startup Venttup has raised $3 million in a pre-Series A funding round co-led by Rainmatter, the investment arm of Zerodha, and Unicorn India Ventures.

The startup, which describes itself as an “Industries 5.0” startup, was incubated at Kerala Startup Mission (KSUM).
Venttup makes critical and precision components and subassemblies for industrial customers, and said its revenue grew fivefold to Rs 10 crore in FY26.
The startup said it will use the capital to expand its engineering team, invest in precision manufacturing and rapid prototyping infrastructure, and adopt AI to improve B2B sourcing, supplier intelligence and operational efficiency.
A large part of that is a new manufacturing facility in Bengaluru. It will handle precision machining, turning and sheet metal production for energy transition, defence, aerospace and space applications.
The startup said the facility should shorten the time it takes a component to go from development and validation to production readiness and mass manufacturing.
“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,” said Sandeep Nair, co-founder and CEO of Venttup.
He said the round would help the startup serve both emerging deeptech companies and established OEMs, and build supply chains for critical sectors under its mission of “India for India, India for the World”.
What Venttup does
Venttup was founded in 2022 by Sandeep Nair, M. Wasim Ankli and Joseph Panakkal. Ankli is COO and Panakkal is CMO. The founders have earlier worked at companies including Hitachi Energy, Siemens Energy, L&T and Kalpataru Power.
The startup runs on a Manufacturing as a Service (MaaS) model. A customer that needs a part brings the requirement, and Venttup handles engineering design, specification standardisation, rapid prototyping, testing, validation and contract manufacturing.
Its work covers precision machining, casting and forging, sheet metal fabrication, box builds, special purpose machines, industrial automation and robotics. It combines in-house engineering with a network of MSME manufacturing partners rather than producing everything itself.
It also offers reverse engineering and indigenisation services, which involve developing locally manufactured alternatives to imported components.
Growth since the seed round
Venttup raised an undisclosed seed round from Unicorn India Ventures in September 2024. At the time, it reported annual recurring revenue of Rs 2 crore and an order pipeline of Rs 20 crore, and said it aimed to grow revenue fivefold within 12 months.
It now reports Rs 10 crore in revenue for FY26. Over the past 12 months, it has added more than 15 large companies as customers and built a business opportunity pipeline of around Rs 30 crore across new energy, mobility and smart infrastructure.
The startup plans to grow across four verticals: energy transition and data centres; aerospace, defence and space systems; smart infrastructure and future mobility; and electronics, automation and smart manufacturing.
Abhinav Singh Negi, who leads climate and deeptech at Rainmatter, said the firm’s own portfolio pointed to the gap Venttup fills.
“When we spoke to our existing portfolio companies about their execution challenges, we consistently realized how difficult it is for hardware startups to find reliable partners who can manage the transition from validation to production,” Negi said.
“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,” he added.
Rainmatter invests in fintech, climate, health and media, and writes cheques between Rs 50 lakh and Rs 100 crore per company, according to its website.
Bhaskar Majumdar, managing partner at Unicorn India Ventures, said the firm has been invested in Venttup since the seed round.
“We 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 for Venttup to help them scale,” Majumdar said.
“Precision manufacturing as a segment is going to experience explosive growth as the deep tech ecosystem matures,” he added.
Unicorn India Ventures said it manages a combined corpus of Rs 2,600 crore across four funds, including the Rs 1,000 crore IITM Frontier Fund co-managed with IIT Madras. Its portfolio includes Genrobotics, EyeROV, Netrasemi and OrbitAID.
The MSME angle
Venttup’s model depends on India’s small manufacturers. In a whitepaper it released at the Kerala Innovation Festival in Kochi in July 2025, the startup said MSMEs contribute 45% of India’s exports but often lack the project management capabilities that global buyers need.
The same paper put India’s aircraft component market at $29.5 billion by 2033, and noted that India spends about 0.7% of GDP on research and development, against 2.4% for China.
