Lasso Security Raises $30M Series A Led by ClearSky Advisors

Lasso Security, an AI security platform providing enterprises with observability, governance, and real-time defense across the AI models they use, the agents they build, and the applications they ship, has raised a $30 million Series A round. The funding was led by ClearSky Advisors.

Round Details

• Round type: Series A
• Amount: $30,000,000 USD
• Date: September 2, 2026
• Lead investor: ClearSky Advisors
• Participating investors: Entree Capital, Singtel Innov8, iAngels, Mindset Ventures, ClearSky Advisors, Swish Data

What Lasso Security Does

Founded in 2023 by Elad Schulman and Ophir Dror, Lasso Security operates from Tel Aviv and New York. The company's platform is designed to give enterprises visibility and control over their AI footprint. It pairs automated red teaming with CPU-based runtime guardrails — LEAP and RAPID — deployed inside customer environments.

This combination addresses two critical enterprise needs: proactively testing AI systems for weaknesses before deployment, and enforcing security policies in real time as models and agents operate in production.

Customer Base

Lasso Security's customers span financial services, insurance, hospitality, automotive, and the US federal government. Named customers include BMW, eToro, Fiverr, Kaufman Rossin, and the Department of Homeland Security.

Why This Matters for Acquirers

The Series A comes as enterprises accelerate AI adoption while grappling with governance, compliance, and security requirements. Lasso Security sits at the intersection of AI infrastructure and cybersecurity — a segment attracting significant strategic interest.

Key considerations for potential acquirers:

• Dual-geography footprint: Operations in Tel Aviv and New York provide access to both deep technical talent and US enterprise relationships.
• Regulated-industry traction: Customers in financial services, insurance, and the federal government indicate the platform meets stringent security and compliance standards.
• Runtime defense differentiation: CPU-based guardrails deployed inside customer environments may offer deployment flexibility compared to GPU-dependent alternatives.
• Founder-led since 2023: A relatively young company with a focused founding team and a clear product thesis.

The new capital is expected to support continued platform development and market expansion as demand for AI security tooling grows.

About the Investors

ClearSky Advisors led the round. Entree Capital, Singtel Innov8, iAngels, Mindset Ventures, and Swish Data also participated. The presence of both venture funds and strategic investors suggests confidence in Lasso Security's approach to securing enterprise AI deployments.

Outlook

As AI models and agents become embedded in critical business processes, the need for observability, governance, and real-time defense will only intensify. Lasso Security's Series A positions it to scale its platform and customer base at a time when AI security is moving from a niche concern to a board-level priority.
