Indian chip startups have completed tape-outs, but the real test is converting engineering wins into paying customers. PoCs, funding, and anchor customers loom.

Indian semiconductor startups have crossed a critical engineering milestone: sending chip designs to foundries for manufacturing. The next phase, industry executives and investors say, is harder.
Over the past year, companies including C2i Semiconductors, AGNIT Semiconductors, Sophrosyne Technologies, Aheesa, Netrasemi and Mindgrove Technologies have completed tape-outs. That means their blueprints are now being turned into physical chips at fabrication plants. A working design does not equal a paying customer.
“A functional product and a tape-out are definitely milestones. It means nothing,” said Sateesh Andra, managing partner at Endiya Partners, an early-stage venture capital fund. “There's a lot more stuff that you need to do. Celebrate it. Then get into revenue mode.”
After tape-out comes testing, benchmarking and sending samples to potential customers. Those proof-of-concept projects, or PoCs, can turn into contracts. The timeline from tape-out to full-scale production ranges from six to 12 months, depending on chip complexity and whether the startup worked with a customer during the design phase.
India has been pushing for self-reliance in semiconductors through the Design Linked Incentive scheme, the Research, Development and Innovation fund and the broader India Semiconductor Mission. The government wants a domestic design ecosystem to cut imports of components used in defence, telecom and computing systems.
Many startups are targeting niche local markets where they believe they can displace existing suppliers.
AGNIT Semiconductors develops gallium nitride chips used in radar and telecom systems. GaN chips are smaller and more energy-efficient than conventional silicon, harder to manufacture at scale. The technology is also subject to export controls in several countries, which co-founder and chief executive Hareesh Chandrashekhar said works in the company's favour.
“If you don't have a component ecosystem feeding into these systems, how are you going to build your systems in the long term?” he said. “That's the question we've started to answer.”
AGNIT currently has five paid PoC projects running. It expects at least two to convert into long-term contracts in the next nine to 12 months.
Sophrosyne Technologies creates chips for medical devices such as diabetes patches and ECG patches. It eventually plans to move into health-tracking devices like smart rings. Founder and chief executive Manish Srivastava said the company's feature set will set it apart.
“When we talk to any customer, price is the last thing we discuss,” he said. “First thing we want to discuss with them is the features of our chip which don't exist across the globe right now.”
Sophrosyne expects to receive its fabricated chips from the foundry within the next month. It plans to begin PoCs in the first quarter of 2027 with one Indian and one UK-based customer. The Bengaluru- and UK-headquartered company has raised $2 million in seed money. Srivastava said the company would need $6 million to $8 million in funding over the next two years.
C2i Semiconductors is focusing on chips that improve heat efficiency for data centres. Its customers are the companies that build those data centres.
Even as these startups move toward revenue, the broader ecosystem lacks anchor customers, Andra said. “Unlike matured ecosystems like the US and China, India is missing anchor customers who come in early in a company's lifecycle so that they can control their destiny a little bit.”
Other hurdles include securing priority access at foundries and matching hardware refresh cycles. Consumer electronics and data centres follow cycles of two to seven years. Foundries back-calculate whether a startup's design will sell millions of chips before giving it priority.
“It's why they'll do it for a startup in the first place, in the hope that they get their business,” said Chinnu Senthilkumar, managing partner at deeptech-focused Exfinity Ventures. “It's why it's important to hire locals in places like Taiwan who have those relationships and know the right people there. Getting priority isn't easy.”
According to Tracxn, 213 semiconductor companies in India have raised funds in 2025. The sector raised $361 million across 44 rounds. So far this year, it has raised $200 million across 27 deals.
