Amplifier Security
Amplifier Security is an AI-native workforce security company that turns the noisy gap between finding and fixing security problems into an automated, employee-friendly workflow. Its agentic platform builds a per-employee Human Risk Graph, then deploys AI agents that engage workers directly in Slack, Teams and the browser to remediate device, app, identity and behavior risks - with humans kept in the loop. Founded in 2023 by Shreyas Sadalgi (CEO) and Tommy Donnelly (CTO), the company has raised roughly $9M and counts security-industry founders and CISOs among its backers and early customers.
Shreyas Sadalgi
Shreyas Sadalgi is the co-founder and CEO of Amplifier Security, an Atlanta- and San Francisco-rooted startup building AI, human-in-the-loop automation that turns employees from security liabilities into active defenders. After two decades in enterprise security strategy and business development at companies like Centrify and BetterCloud, he teamed up with three-time CISO Tommy Donnelly to tackle security's 'last mile' problem: the gap between what security policy says and what busy humans actually do. Amplifier has raised roughly $9 million, including a $5.6M seed round led by TechOperators in 2025.
