CloudSEK, an AI-powered cyber threat prediction and intelligence firm, has raised $19 million across its Series A2 and B1 funding rounds from MassMutual Ventures, Inflexor Ventures, Prana Ventures, Tenacity Ventures, and select strategic investors, including Commvault.
The round also saw participation from existing investors, including the Meeran Family (founders of Eastern Group), StartupXSeed, Neon Fund and Exfinity Ventures.
The newly raised funds will be used for product innovation, global expansion, AI model enhancements and platform integrations.
Founded in 2015 by Rahul Sasi, CloudSEK is an AI-powered Digital Risk Monitoring platform that provides real-time visibility of cyber threats and actionable intel. CloudSEK leverages contextual AI to predict and prevent cyber threats.
“We built CloudSEK to predict the initial attack vector and stop threats before they hit the headlines with the goal of preventing threats before they escalate. Unlike conventional threat intelligence that focuses on indicators of compromise after an attack, our platform detects the earliest signals—leaked credentials, exposed APIs, compromised vendors—weeks before an incident unfolds. That’s our version of threat intelligence: predictive, not forensic,” said Rahul Sasi, Co-founder & CEO of CloudSEK.
“Today, over 60% of our net new revenue comes from international markets, with the U.S. emerging as our fastest-growing region. We’ve achieved this scale while staying cash flow positive. This round—backed by top financial and strategic investors—not only validates our vision but reinforces what we’ve believed from day one: cybersecurity must be proactive, not reactive,” he added.
“CloudSEK has grown 3x in ARR over the last 24 months and continues to grow well above industry standards. The round attracted significant interest from global financial investors, and we will soon be announcing Series B2 as an extension of B1, both to onboard new investors and to facilitate partial exits for some of our early backers,” said Kalyan Kumar Vattipalli, VP of Finance at CloudSEK.
“CloudSEK has created a great product based on cutting-edge AI, appropriate for the security needs of top global companies. Tenacity is excited about backing and working closely with Rahul and his team to help build a great global technology product company from India,” said Rohit Razdan, Partner, Tenacity Ventures.
