AI-Powered Pentesting Startup Strike Raises $13.5M to Redefine Cybersecurity

Strike, the NYC-based cybersecurity startup pioneering AI-driven continuous penetration testing, just raised $13.5 million in Series A funding. The round was led by FinTech Collective, with participation from Galicia Ventures and strong follow-on backing from existing investors like Greyhound Capital, FJ Labs, Canary, and Carao. This brings Strike’s total funding to $19 million.

Founded in 2022 by Santiago Rosenblatt, a child prodigy hacker who famously breached systems like the NBA and PayPal before turning to cybersecurity, Strike is on a mission to automate 50% of the pentesting process and crack eight figures in ARR by 2025.

Disrupting Traditional Pentesting

Traditional pentesting is outdated—slow, expensive, and reactive. Strike flips the script with AI + elite ethical hackers, offering:

• Pentests in hours, not weeks

• Real-time vulnerability monitoring

• Instant compliance reports for SOC2, HIPAA, PCI DSS, ISO27001

Strike’s approach is already trusted by 100+ enterprises across finance, tech, and healthcare—including Santander, Mercado Libre, Okta, and Delivery Hero—and has driven 3x year-over-year growth.

Enter: Strike360

Now Strike is leveling up with Strike360, its AI-powered pentesting engine. It automates security testing from discovery through to remediation, using machine learning to:

• Detect hidden vulnerabilities in seconds

• Eliminate false positives

• Simplify compliance workflows

• Enable continuous, scalable testing

Scaling in the U.S. and Brazil

With momentum building, Strike is expanding fast. CEO Rosenblatt has relocated to the U.S. to lead growth with a 14-person stateside team. Meanwhile, a new São Paulo HQ with a 7-person squad is set to capture demand in Brazil’s booming cybersecurity market.

What’s Next?

Strike is already operating in over 20 countries and has bold plans to scale even further, with new product innovations on the horizon.
