Promptfoo Secures $18.4 Million Series A for AI Security Advancements

In a significant move towards bolstering AI security, Promptfoo, the open-source framework designed for AI red-teaming and security testing, has raised an impressive $18.4 million in its Series A funding round. This latest financial support, spearheaded by Insight Partners and accompanied by participation from existing investor Andreessen Horowitz, marks a pivotal step in the company’s mission to establish itself as a leading player in AI security solutions.

Founded in 2024, Promptfoo has quickly gained a reputation as a cornerstone in the realm of AI security testing. With over 100,000 developers utilizing its open-source tools, Promptfoo is already assisting major players in the corporate world, including more than 30 Fortune 500 companies, to secure large language models (LLMs) and generative AI applications. The platform plays a vital role in identifying potential risks such as prompt injection, data leaks, and misuse of insecure tools.

The recent influx of funding comes at a crucial time for organizations embracing AI technologies. As enterprises transition from experimental phases to full-scale deployments, the accompanying complexities and risk profiles have significantly increased. Ian Webster, CEO and co-founder of Promptfoo, acknowledged that AI security has now become a critical barrier preventing companies from efficiently rolling out generative AI applications. He pointed out that evolving architectural frameworks like RAG, agents, and the recent MCP developments have expanded AI capabilities but also heightened vulnerabilities, thereby broadening the attack surface for potential cyber threats.

What sets Promptfoo apart in the competitive landscape of AI security is its comprehensive approach. It uniquely integrates automated red-team tests into the build and release sequence, presenting clear actionable remediation steps alongside. The platform seamlessly feeds results into the existing vulnerability management workflows, offering organizations a cohesive end-to-end automation experience. This integration encompasses attack objective generation, exploit searches, and regression testing, equipping security and engineering teams with a unified and ongoing workflow for fortifying complex AI-driven systems.

Ganesh Bell, Managing Director at Insight Partners, commended Promptfoo for creating what he considers a category-defining product. He noted the layers of security emerging around AI technologies are transcending traditional frameworks, positioning Promptfoo as an essential component in the evolution of intelligence-first design and secure Enterprise AI. He emphasized the necessity for thorough security testing amidst the competitive landscape of AI deployment, asserting Promptfoo's significant traction and technical depth make it ideally suited to seize this expanding market opportunity.

In response to this substantial funding, Promptfoo aims to scale its operations and solidify its position as the industry standard for enterprise AI security. The company intends to grow its team and accelerate the development of its platform to cater to growing demand from Global 2000 companies that seek comprehensive solutions for safeguarding their AI implementations.

Zane Lackey, General Partner at Andreessen Horowitz, reflected on his firm's initial investment in Promptfoo, predicting that AI security would become a vital concern for all enterprises. He noted that in just one year, Promptfoo has validated this prediction and exceeded expectations, asserting that their continued support results from confidence in the company's future impact on the AI security landscape.

Promptfoo stands as the most widely adopted open-source AI security testing platform designed for enterprises, enabling them to identify and rectify vulnerabilities in their AI systems before they go live. With its rapid growth and the substantial backing of renowned investors, Promptfoo is poised to lead the charge in securing AI innovations across sectors including retail, telecommunications, finance, and media.
