Israeli cybersecurity company Daylight has raised $80 million in a Series B round led by Growth Equity at Goldman Sachs Alternatives, bringing its total funding to $120 million, Calcalist reported on 10 November. Calcalist estimates the valuation at approximately $400 million; the company did not disclose it.
By our arithmetic, the new round is twice everything Daylight raised before it: $120 million in total minus the $80 million Series B leaves $40 million from its seed and Series A rounds.
Business Pill · Run-Rate Revenue
A short Business Engineer explainer on run-rate and recurring revenue. It teaches the general idea only and does not discuss Daylight.
The key insight: Goldman Sachs Alternatives led an $80 million Series B in Daylight, Calcalist reports, and by our arithmetic the round is twice the $40 million the company raised in its seed and Series A combined ($120 million total minus $80 million).
Daylight combines AI agents with human security experts to detect, investigate and respond to cyber threats, Calcalist says. Okta Ventures, the investment arm of Okta, joined as a new investor, alongside existing backers Bain Capital, Craft Ventures, Vintage Partners and Maple Capital.
The company was founded in early 2025 by CEO Hagai Shapira and CTO Eldad Rudich, both formerly of Torq, and employs 80 people, 43 of them in Israel, according to Calcalist. Its customers include Fortune 500 companies and AI businesses such as Lovable, LastPass, Rogo, dLocal and Miro.
Daylight’s funding by round, from Calcalist’s reports. The $40 million earlier total and the 2x ratio are our arithmetic ($120 million total minus the $80 million Series B).
Three Rounds Since 2025
Calcalist’s earlier reports list a $7 million seed round and a $33 million Series A that followed three months later. By our arithmetic, those two add up to the $40 million that the new total implies, and the Series B is about 2.4 times the Series A ($80 million / $33 million).
Daylight said its revenue has grown more than 40-fold over the past year, driven by demand from large enterprises and AI-native companies, and that it expects to generate tens of millions of dollars in revenue by the end of 2027, Calcalist reports. Dealroom notes the figures are self-reported.
Where the Money Goes
Shapira told Calcalist: “We are seeing very substantial revenuegrowth right from the start, and we want to maintain that momentum. Most of the capital will be used to expand our sales team”.
Calcalist says the company plans to use the funding to expand in the U.S., enter markets across Europe, the Middle East, Africa and the Asia-Pacific region, and grow its engineering and technology teams.
Agents Plus Engineers
Daylight’s security engineers develop and customise the agents for each client’s systems, workflows and risk profile, Calcalist says. The agents handle much of the day-to-day work, while human specialists focus on decisions requiring judgment. The company says its response times are up to 10 times faster than those of traditional managed security service providers.
It is also extending detection to risks from AI use inside companies, including prompt injection attacks and Model Context Protocol (MCP) integrations, Calcalist reports. Earlier today we covered Bay’s $50 million launch to secure AI agents, a second funding round aimed at the same agent-security layer.
The Structural Read
As we read the Calcalist report, the round prices growth the company gives only as a multiple: revenue up more than 40-fold over the past year, with no dollar figure disclosed.
As we read it, the money is aimed at distribution more than product: Shapira told Calcalist most of the capital will be used to expand the sales team.

Three Implications
FOR SECURITY BUYERS Calcalist says Daylight claims response times up to 10 times faster than traditional managed security service providers; the figure is the company’s own.
FOR AI-NATIVE COMPANIES Customers named by Calcalist include Lovable, LastPass, Rogo, dLocal and Miro, and the company is adding detection for prompt injection and MCP integrations.
FOR EARLY INVESTORS The Series B is about 2.4 times the $33 million Series A, by our arithmetic.
The framework argues: “SaaS is charged for access to tools. AGaaS charges for the execution of outcomes.”
As we read it, Daylight sells the second model in security: agents plus engineers that detect, investigate and respond for the client, as Calcalist describes it, rather than a tool the client’s own team runs.
What Is Not Established
We did not find a Daylight release when we read the reports; the figures are as reported by Calcalist, and the valuation is Calcalist’s estimate. Daylight has not given a revenue figure, so the 40-fold growth cannot be put in dollar terms, and no valuation for the earlier rounds was disclosed, so the size of the step-up is unknown.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Goldman Sachs Alternatives led an $80 million Series B in Daylight at an estimated $400 million valuation, Calcalist reports. By our arithmetic, the round is twice the $40 million the company raised in its first two rounds, and Shapira said most of it will go to the sales team.
A note on sourcing. Figures are from Calcalist’s report of 10 November 2026; the valuation is Calcalist’s estimate, and no Daylight release was available when we read it. The earlier-funding total and the ratios are our arithmetic.
