About

Hi there, I'm Ron, CTO of Guardbase — a startup currently in stealth mode. We are building the security and control plane for coding agents and MCP servers. Full visibility and control over every coding agent in all your teams. Backed by top-tier angel investors from organizations like Darktrace and Deutsche Bank. Before Guardbase, I co-founded Flipbase, which provided seamlessly integratable video experiences for recruitment professionals and ATS vendors.

  • Co-Founder & CTO at Stealth Startup
    May 2025 - Present · 1 yr 2 mos

    Building the security plane for coding agents and MCP servers. Full visibility and control over every coding agent in all your teams. We started out by red teaming AI applications for enterprises. We kept finding the same thing: through prompt injections we could exploit agents because of too many permissions and no oversight. So we decided to fix that. Backed by top-tier angels that made exits to companies like Darktrace.
