Prime Security, which offers an AI-powered platform to help security teams detect, prioritize, and mitigate risks at the software design phase, today announced a $20 million Series A funding round.
Founded in 2023 and headquartered in New York with offices in Tel Aviv, the company has developed what it calls an “Agentic Security Architect” that autonomously conducts security design reviews and proactively identifies design flaws across development work.
Winner of the Black Hat 2025 Startup Spotlight this summer, Prime says it is already working with high profile companies, including PayPal, Qualtrics, Bumble, ThoughtSpot, Redis Labs, and others.
“Prime Security’s autonomous, design-stage reviews give us continuous and adaptive visibility across our engineering ecosystem, enabling us to identify and address risks earlier in the software development lifecycle,” said Shaun Khalfan, CISO at PayPal. “This capability helps us move with speed and confidence to deliver for our customers and strengthen trust in our business globally.”
Prime explains that, by providing continuous, automated security assessment of all planned work, its platform empowers security teams to focus on strategic architecture while ensuring comprehensive coverage of every feature, enhancement, and change flowing through the development pipeline.
The round was led by Scale Venture Partners, and included participation from Foundation Capital and Flybridge Ventures.
