Sources: Onavo co-founder Roi Tiger is closing a $55M Series A led by Greenoaks for his stealth cybersecurity startup at a valuation in the hundreds of millions

Context & Ripple Effects
The reported round follows a run of sizable cybersecurity financings tied to Israel: Oligo Security's $50M Series B was disclosed in January, while enterprise-browser company Island emerged from stealth with roughly $100M earlier in the cycle. Tiger's new company would enter that funding environment before publicly detailing its product.
The significance is less a disclosed product milestone than the ability of a founder with prior company-building experience to secure a large, high-valuation first institutional round while remaining in stealth.
First-order effects
- The unnamed startup would gain the reported $55M to build its cybersecurity product, recruit, and establish go-to-market capacity without an immediate public launch.
- Greenoaks would become the reported lead investor in a company valued in the hundreds of millions, giving the firm early exposure to Tiger's next venture.
Second-order effects
- The financing raises the competitive benchmark for other stealth and early-stage cybersecurity companies seeking capital, particularly those pitching investors before broad product visibility.
- A well-capitalized entrant can intensify competition for specialized security talent and enterprise design partners, even though its product category has not been disclosed.
Third-order effects
- If comparable rounds continue, cybersecurity venture funding may become more concentrated in repeat founders and a smaller set of investors able to support large early rounds.
- The pattern could widen the gap between heavily financed stealth companies and startups that must validate products and revenue before accessing similar capital.
The trend: Cybersecurity investing is increasingly rewarding founder pedigree and strategic optionality with substantial capital before a company's product is publicly defined.
