Cyberstarts Closes Second $380M Opportunity Fund to Back the Next Stage of Cybersecurity Breakouts

Audio By Carbonatix

TEL AVIV, Israel--(BUSINESS WIRE)--Sep 30, 2025--

Cyberstarts, the leading early-stage cybersecurity venture firm, today announced the close of its second Opportunity Fund (“Opportunity Fund II”), a $380 million investment vehicle dedicated to supporting portfolio companies as they scale from early-stage startups to global, growth-stage businesses.

This new fund reflects the continued success of a distinctive strategy that Cyberstarts has cultivated over the past seven years – backing visionary founders at inception, pressure-testing ideas through its advisory community of CISOs, and remaining deeply involved at every stage of the company-building journey.

“Founders don’t need more noise, they need focused, high-conviction support at the moments that matter most,” said Gili Raanan, Founder of Cyberstarts. “This new fund gives us the ability to scale our involvement precisely when founders ask us to lean in the hardest – whether that’s in leading or anchoring future capital raises, mobilizing our network to accelerate business development, or helping teams recruit key talent for their next phase of growth.”

The success of the Cyberstarts model is evident across its portfolio of category-defining companies. Wiz, a leading cloud security platform and Cyberstarts portfolio company since 2020, has emerged as one of the fastest-growing software businesses in history and, earlier this year, entered into an agreement to be acquired by Google for $32 billion. Fireblocks, a Cyberstarts portfolio company since 2019, recently reached an $8 billion valuation by securing digital assets for the world’s leading financial institutions. Island, the creator of the enterprise browser, has scaled to a nearly $5 billion valuation, and Cyera, an AI-native data security platform, has reached a valuation of $6 billion amid rapid enterprise adoption – both after receiving investments from Cyberstarts in 2022 and 2021, respectively. Beyond these hypergrowth stories, portfolio companies such as Axis Security, Avalor, Bionic, Dazz, Noname, and Trail have all been successfully acquired, reinforcing how Cyberstarts’ early conviction and hands-on partnership can drive market-shaping outcomes.

“Opportunity Fund II is designed to double-down when our portfolio companies are at key inflection points,” said Lior Simon, General Partner at Cyberstarts. “As seed-focused investors, there is nothing that makes us prouder than the success of our early bets and this new fund will give us the opportunity to have even more impact alongside our most valued founders.”

“Cyberstarts was built on the belief that authentic relationships can transform markets,” said Hila Zigman, General Partner at Cyberstarts. “With Opportunity Fund II, we’re deepening our existing relationships with founders who are already reshaping the world and creating new pathways for continued innovation.”

Earlier this year, Cyberstarts also announced the launch of a $300 million Employee Liquidity Fund. Following the close of Opportunity Fund II, Cyberstarts will have raised over $700 million in 2025 alone and will now have over $1.4 billion in total capital commitments across seven funds.

The Team

Cyberstarts is backed by highly-accomplished cybersecurity experts, each with unique experience and insights that allows the firm to identify and invest in companies that are redefining the industry landscape. The team includes general partners Dor Knafo, Hila Zigman, Lior Simon, Gili Raanan, and operating partners Adam Aarons and, newly, Pete Chronis.

“We are pleased to welcome Pete to the Cyberstarts team,” continued Raanan. “His distinguished track record as a CISO brings valuable perspective that will strengthen our partnerships with the visionaries shaping the future of cybersecurity.”

“I have always been a firm believer that security innovation moves fastest when operators and entrepreneurs work together,” said Pete Chronis, Operating Partner at Cyberstarts. “As part of the Cyberstarts team, I’m committed to helping the next generation of cybersecurity companies grow stronger, scale smarter, and secure the digital economy.”

Chronis joins Cyberstarts after a lengthy career as CISO at some of the world’s leading media and telecommunications companies, including Paramount, WarnerMedia, Turner Broadcasting, and EarthLink. He currently serves on the Board of Cyera, one of the world’s fastest growing cybersecurity companies. He has also authored several books, including The Cyber Conundrum (2018), Hidden Lessons from History (2020), and Modern DSMP for Dummies (2024).
