Exfinity Venture Partners records 13x return after partial exit from cybersecurity firm CloudSEK

Deeptech venture capital firm Exfinity Venture Partners has announced a partial exit from its investment in cybersecurity platform CloudSEK. The early-stage investor said the deal delivered a 13x return on invested capital and an internal rate of return (IRR) of over 40%.

The transaction was carried out in January as a secondary sale to existing investors. However, Exfinity clarified that it continues to hold a meaningful stake in the company.

Exfinity had first backed CloudSEK during its pre-Series A stage, at a time when cybersecurity solutions were largely focused on reacting to threats after they occurred. The firm supported the company’s early vision of building a predictive, intelligence-led cybersecurity platform.

Over the years, CloudSEK has evolved into an AI-driven threat intelligence platform. It now helps enterprises identify and stop cyber threats in advance across areas such as digital risk, attack surfaces and supply chains. The platform focuses on mapping connected attack paths instead of treating threats as isolated alerts.

The company recently crossed $15 million in annual recurring revenue (ARR) and has maintained consistent year-on-year growth. More than 60% of its new revenue now comes from international markets, with the United States emerging as its fastest-growing region.

In early 2025, the company raised over $20 million in its Series B funding roundr.

“CloudSEK is one of the clearest examples of what Indian deep-tech can achieve on the global stage. Our early conviction in Rahul and his team has been validated by the company’s ARR trajectory, enterprise client quality, and now, by the confidence of a global strategic player like Commvault. This is a calibrated partial exit - we remain invested and excited about what comes next,” said Chinnu Senthilkumar, Managing Partner at Exfinity Venture Partners.

“Exfinity was our first institutional investor and backed us at a time when few were willing to take a bet on a cybersecurity platform emerging from India. Beyond capital, they have been a true partner, supporting us across early customer introductions, follow-on fundraising, and strategic direction as we scaled globally,” added Rahul Sasi, Founder & CEO at CloudSEK.

The latest transaction adds to a series of exits by Exfinity from its 2016 Fund II.

The firm has previously exited investments in Kinara.ai and Locus, and also made a partial exit from Pixis.
