About
PromptArmor is a cybersecurity company specializing in protecting AI systems and large language model (LLM) applications from adversarial attacks — particularly prompt injection, jailbreaking, and data exfiltration through AI interfaces. As enterprises deploy AI assistants, chatbots, and autonomous agents at scale, new attack surfaces emerge: malicious users can craft carefully worded inputs that bypass AI safety guardrails, extract confidential information from AI systems, or manipulate AI agents into taking unintended actions. PromptArmor develops detection and mitigation tools for these AI-specific vulnerabilities.

About
Seal Security is a Tel Aviv, Israel-based open source vulnerability patching platform — backed by Y Combinator (W20) with $20 million in total funding from MORE Investment House, SBI Insurance Group, Crew Capital, Cyber Club London, and PayPal Alumni Fund — providing development and security teams with standalone, production-ready security patches for open source software vulnerabilities that fix critical CVEs without requiring version upgrades or introducing breaking changes to application dependencies, Linux systems, and container-based images. Founded in 2020, Seal Security enables organizations to remediate critical vulnerabilities quickly — decoupling the security fix from the broader version update that typically breaks downstream functionality and triggers weeks of regression testing.
