Cylake raises $245M ahead of cyber platform beta

Cylake has raised an unusually large amount of capital before broadly launching its cybersecurity platform.

What happened

The company raised $245 million through a convertible note from Lightspeed Venture Partners, Picture Capital and Redpoint Ventures, taking total funding to $290 million. Its AI-native cybersecurity platform is expected to enter beta by the end of 2026, with broader availability planned for 2027.

Why it matters

Cybersecurity buyers increasingly need to secure cloud systems, AI workloads and regulated infrastructure at the same time. Investors are betting that a new generation of security companies can redesign the stack around AI-era threats rather than bolt AI onto older products.

The bigger picture

The financing shows how much capital is flowing into cybersecurity before product-market fit is fully visible. In strategic software categories, teams and technical ambition can now attract growth-scale capital much earlier than traditional SaaS businesses.
