QpiAI, the Bengaluru-based company building quantum computers and artificial intelligence software, has raised ₹50 crore in debt from InnoVen Capital, a financing that offers an unusual window into how lenders are beginning to price the risk of India's nascent quantum hardware industry.
According to regulatory filings first reported by Entrackr on 5 October 2026, QpiAI's board approved the issuance of 5,000 non-convertible debentures with a face value of ₹1 lakh each to InnoVen Capital India Fund II. The debentures carry an annual coupon of 13.85% and are scheduled to mature by 1 December 2028. The board resolution was passed on 28 August, and the company has not disclosed how it intends to use the proceeds.
In a sector that globally relies almost entirely on equity and government grants, a fixed-rate debt instrument for a quantum hardware company is a notable development. It suggests that at least one specialist lender believes QpiAI's assets, backers and strategic position are strong enough to support regular interest payments.
A company at the centre of India's quantum plans
QpiAI has become one of the most visible private companies in India's quantum effort. It develops proprietary quantum hardware and software, targeting applications in drug discovery, materials science, manufacturing, finance and logistics, and pairs that work with AI tools for enterprise customers. In 2025 it unveiled what it described as India's first full-stack 25-qubit quantum computer.
Its funding history tracks the country's growing interest in the field. The company raised $6.5 million in a pre-Series A round in June 2024, led by YourNest and SIDBI Venture Capital. It followed that with a $32 million Series A in July 2025, co-led by Avataar Ventures and the National Quantum Mission, the government programme created to build domestic capability in quantum technologies. Entrackr estimated at the time that the round valued QpiAI at around ₹2,050 crore, or about $215 million.
That brings disclosed equity funding to roughly $38.5 million before the new debt. The participation of the National Quantum Mission as an investor, rather than merely a grant-maker, gives QpiAI a quasi-strategic status that lenders are likely to have weighed heavily.
Why debt, and why now
For a company at QpiAI's stage, debt is an unconventional choice. Quantum hardware businesses typically have long development cycles, limited near-term revenue and heavy capital requirements. Equity investors accept those characteristics in exchange for potential upside; lenders usually do not.
The arithmetic illustrates the trade-off. Annual interest on ₹50 crore at 13.85% amounts to roughly ₹6.9 crore. Analysis by StartupFox, citing filings, put QpiAI's FY25 operating revenue at about ₹2 crore, meaning a single year of interest would exceed that revenue several times over. On the other hand, raising the same ₹50 crore through equity at the company's last estimated valuation would have meant giving up about 2.4% of the business.
For founders who expect their company's value to rise substantially as hardware milestones are reached, avoiding dilution can justify a high coupon. Venture debt is also typically quicker to arrange than a new priced equity round and does not require the company to defend a fresh valuation in a market where investors have become more selective about deep technology.
Industry commentators have suggested that the proceeds may support the capital-intensive work of building out QpiAI's own chip fabrication capability, though the company has not confirmed this. Quantum processors require specialised fabrication, cryogenic systems and precision engineering, all of which consume significant capital before generating revenue.
