imper.ai is a Brooklyn-based cybersecurity startup founded by cyber-intelligence veterans, led by co-founder and CEO Noam Awadish, to defend organizations against AI-driven impersonation and social-engineering attacks. Its agentless platform provides real-time identity verification and impersonation detection, analyzing device, network, and environmental signals to detect attacker-controlled environments and confirm a person's authenticity without documents or biometric enrollment. It covers major communication channels including Zoom, Teams, Slack, WhatsApp, and Google Workspace, and addresses use cases from help-desk vishing and hiring fraud to deepfake video and voice-clone attacks. imper.ai launched from stealth in December 2025 with a $28M round led by Redpoint Ventures and Battery Ventures, with Maple VC, Vessy VC, and Cerca Partners participating.
