Indian Startup Quanfluence Raises $10M to Build a Quantum Machine

Bengaluru-based Quanfluence has raised $10 Mn (~₹92 Cr) in a funding round led by Chiratae Ventures, with participation from Rainmatter by Zerodha and existing backer Pi Ventures.

This is a 5x jump from the $2 Mn seed round the startup raised barely ten months ago in December 2024 an unusually fast follow-on for a deep-tech company still years away from a commercial product.

What makes this round interesting isn't just the pace of the raise it's that Quanfluence is building something almost no one else in India is attempting: a quantum computer that runs on light instead of electricity, at room temperature, while most quantum rivals still need extreme refrigeration just to function.

The Details

• Round size$10 Mn (~₹92 Cr)
• Lead investorChiratae Ventures
• Also participatingRainmatter by Zerodha, Pi Ventures (existing investor)
• ValuationNot disclosed
• Previous round$2 Mn seed (December 2024), led by Pi Ventures with Golden Sparrow and angel investor Reena Dayal
• Implied jumproughly 5x the size of its seed round, in under a year

Quantum Computing Without the Deep Freeze

Founded in 2021 by Sujoy Chakravarty, Ravi Mehta, Biman Chattopadhyay, Anil Prabhakar, Aditi Vaidya and Sandeep Goyal, Quanfluence builds photonic quantum computing technology meant to tackle optimisation problems the kind that show up in logistics routing, financial risk modelling and delivery planning.

The technical bet is what sets it apart. Conventional quantum computers typically need complex cryogenic cooling to function. Quanfluence's system combines optics and hardware to operate at room temperature a meaningfully lower barrier to real-world deployment.

The company's current product, an Optical Ising Machine, already handles up to 20,000 variables, with a next-gen version targeting 100,000. It's also testing a system capable of processing 10-25 million permutations for complex optimisation tasks.

Early Revenue, Still a Long Runway Ahead

Quanfluence has already sold around three machines and is running paid pilots with 10-15 corporations genuine commercial traction for a company this early in the quantum computing curve.

The fresh capital will fund a four-qubit quantum computer in the near term, with a much larger 100-qubit prototype targeted by 2029. The company's stated ambition is a fault-tolerant, general-purpose quantum computer within five to six years.

That's a long horizon by startup standards, but a standard one for quantum computing where even well-funded global players like Canada's Xanadu have taken a decade-plus and $100 Mn+ in cumulative funding to get close to commercial viability.

Riding India's Quantum Push

This raise also lands inside a bigger national push. The government's National Quantum Mission carries a ₹6,000 Cr budget and an eight-year roadmap to build India's quantum capability, with grants of ₹10-50 Cr earmarked for 10-15 quantum startups.

Quanfluence, incubated at the IITM Incubation Centre, is positioned as one of the mission's flagship private-sector bets a signal that this round likely benefits from policy tailwinds as much as pure investor conviction.

What the Timeline Doesn't Show You

A 5x round-size jump in under a year for a pre-revenue-scale deep-tech company is rare, and it usually means investors are betting on the mission, not current traction. Three machines sold and a handful of pilots is a credible start, but it's a long distance from a fault-tolerant, 100-qubit system by 2029. Quantum computing globally is littered with ambitious roadmaps that slipped by years Quanfluence's room-temperature approach is a genuine technical edge, but execution risk over a 5-6 year horizon is the real variable here, not capital.

The Bottom Line

Quanfluence has investor conviction and a national mission behind it what it needs next is proof that its optical approach can scale from three machines to a real installed base before the 2029 deadline arrives.
