YL Ventures
YL Ventures operates from Mill Valley and Tel Aviv as a venture capital firm exclusively dedicated to cybersecurity. The firm focuses on Israeli founders from the earliest stages, providing a bridge to the US enterprise market. Its model is built on a combination of deep domain expertise, an in-house CTO, and an advisory board of leading chief information security officers who help shape product roadmaps, validate technology, and accelerate customer acquisition for portfolio companies. The firm's strategy spans seed, early-stage, and growth investments, with a portfolio concentrated on enterprise security infrastructure, cloud security, data protection, and the emerging layer of AI-native security. YL Ventures writes initial checks at inception and reserves significant capital for follow-on rounds, often leading or co-leading financings. Confirmed positions include Native, an AI runtime security and application detection and response platform that raised $42 million, and an active portfolio covering cloud security control planes, AI pentesting, agentic development security, and non-human identity management. The firm deploys primarily into Israel but structures investments to support go-to-market execution in North America. YL Ventures manages $800 million in total capital. The firm was recognized by PitchBook as a top-10 cybersecurity venture capital investor in 2022, 2023, and 2024. In 2025, it published its State of the Cyber Nation report, an annual analysis of the Israeli cybersecurity ecosystem, reinforcing its role as an information node for enterprise buyers and co-investors. YL Ventures does not operate a separate philanthropic foundation or multi-family office structure. What distinguishes YL Ventures structurally is its deep coupling of investment capital with an operational advisory apparatus that functions like an outsourced early go-to-market team. Rather than relying on generalist networks, the firm embeds its portfolio companies with a dedicated network of practicing CISOs who serve as design partners and reference accounts — a sourcing and validation moat that is difficult for broader venture platforms or corporate venture arms to replicate in a specialist security context.

Frequently asked questions
Does YL Ventures invest exclusively in cybersecurity?
Yes. The firm's entire mandate is dedicated to cybersecurity, covering sectors such as cloud security, AI security, data loss prevention, identity management, and application security. YL Ventures has maintained this specialist focus for nearly two decades and does not invest in other technology verticals.
How does YL Ventures support its portfolio companies beyond capital?
YL Ventures deploys an operational model that includes an in-house CTO and an advisory board of Fortune 500 CISOs. This network acts as a product validation channel, providing early design partnership, reference calls, and introductions to enterprise buyers. The firm also guides go-to-market strategy, executive hiring, and follow-on fundraising.
Where does YL Ventures source its investments?
The firm concentrates its origination efforts in Israel, where it has a physical office in Tel Aviv and decades of relationships within the cybersecurity founder community. Investments are structured to help these Israeli companies build a commercial presence in the US, leveraging YL Ventures' network of North American security executives.
What is the advisory board model at YL Ventures?
YL Ventures maintains a formal advisory board composed of senior cybersecurity leaders, primarily sitting CISOs from large enterprises. These advisors do not simply consult at quarterly meetings; they engage with portfolio companies from the seed stage, acting as active design partners who pressure-test product assumptions and accelerate the enterprise sales cycle.
Does YL Ventures manage any fund-of-funds or co-investment vehicles for outside LPs?
The firm operates as a direct venture capital investor and does not publicly disclose a fund-of-funds program or a formal co-investment club structure for non-institutional limited partners. Its vehicles are designed for primary commitments into early-stage cybersecurity startups.
