GhostEye
GhostEye is a Y Combinator-backed continuous red-team service that simulates real-world social-engineering attacks — help-desk vishing, deepfaked executive calls, and MFA-fatigue campaigns — to reveal which of an organization's exploitable gaps a real adversary would actually use.

GhostEye runs ongoing, realistic red-team engagements that emulate the social-engineering techniques increasingly used in real breaches: vishing calls impersonating help-desk staff, deepfaked executive voice or video, and MFA-fatigue push-bombing campaigns, rather than only testing technical vulnerabilities in isolation.
The company went through Y Combinator’s Summer 2025 batch and is based in New York City, addressing the gap between traditional penetration testing (which rarely covers voice-based deepfake social engineering) and the reality of how attackers are now using generative AI to impersonate trusted colleagues.
Innovation Matrix Assessment
As a 2025-founded company, GhostEye has already built a functioning continuous red-team service covering vishing, deepfake impersonation, and MFA-fatigue testing, a fast initial build for its stage.
Testing organizations against the specific social-engineering techniques attackers currently use gives security awareness and incident-response teams more actionable, current risk data than generic annual pentests.
As a very early-stage YC company with no disclosed funding round beyond standard YC investment and no named enterprise customers found, independently verifiable market traction is currently limited.
Treating AI-enabled voice/video social engineering as a distinct, continuously-tested discipline is a meaningful departure from how traditional penetration testing firms have historically scoped engagements.
As an extremely early-stage company, no independent efficacy data or third-party case study was found; effectiveness is currently unverified beyond the company's own description.
AI-generated voice and video impersonation is a fast-growing, well-documented attack vector cited across multiple industry fraud reports, giving this specific red-team discipline strong forward-looking relevance.
Why CISOs Should Care
Generative AI has made deepfaked voice and video impersonation cheap and accessible to attackers, and most security awareness programs and penetration tests haven't caught up; GhostEye tests organizations against the specific techniques attackers are actually using today.
What Makes It Different
GhostEye focuses specifically on AI-enabled social engineering — deepfake voice/video impersonation and vishing — as a distinct testing discipline, rather than treating it as a minor add-on to traditional technical penetration testing.
The Matrix Verdict
47/100 — EMERGING / UNRANKED
A very early-stage but well-timed red-team specialist addressing the specific, fast-growing threat of AI-enabled social engineering; scores are conservative given its very recent founding and lack of disclosed funding or customer data.
Editorial Note: Claims vs. Verified Findings
YC batch and headquarters are independently confirmed via GhostEye's Y Combinator company page; specific funding amount, team size, and customer engagement outcomes are not disclosed.
