Daylight raises $80M Series B led by Goldman Sachs Alternatives for AI security
An Israeli-founded cybersecurity company with headquarters in New York and Tel Aviv said it closed an $80 million Series B on November 10, 2026. Growth Equity at Goldman Sachs Alternatives led the round. Okta Ventures, the investment arm of identity vendor Okta, joined as a new investor, while Bain Capital, Craft Ventures, Vintage Partners and Maple Capital returned from earlier rounds. Total funding now stands at $120 million, per Calcalist.
The company sells managed security operations rather than standalone software. AI agents monitor systems, investigate suspicious activity and help with response, while security engineers tailor those agents to each client's systems and workflows and make judgment calls. Its Aura platform offers natural-language investigations and a central security data store. Daylight says revenue grew more than 40-fold over the past year, driven by Fortune 500 and AI-native customers, and that it detects threats in seconds and contains them within minutes, up to 10 times faster than traditional managed providers. The company has 80 employees, 43 of them in Israel.
Daylight did not disclose a valuation. Globes reported, citing sources, that the round was raised at a company valuation of about $400 million, and Calcalist described that figure as an estimate. The new capital will fund a larger U.S. presence, entry into markets across Europe, the Middle East, Africa and Asia-Pacific, hiring in security engineering and technology, and faster product development.
Why it matters
For builders, the deal suggests buyers will pay for agent-driven response when a person reviews decisions at defined points. Teams selling autonomous security tools should prepare for questions about how escalations are routed, which actions require analyst sign-off, and who is accountable when an agent acts. Products that show those boundaries clearly may earn buyer trust more easily than products that promise full automation.
For investors, the round shows growth capital flowing into a model that depends on staff as well as software. CFO Tech reported that Goldman Sachs sees cybersecurity spending as resilient as companies manage rising alert volumes. Investors evaluating similar companies should test how service delivery costs rise with customer count, and whether human review becomes a margin drag or a lasting advantage.
