YL Ventures

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.

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.

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.

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.

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.
