About Grudko Associates
Investigation and intelligence consulting delivering court-ready evidence since 1980.
Founded on Integrity, Evidence and Investigative Discipline
Grudko Associates was founded in 1980 by Andy Grudko and Judy Grudko with a clear and uncompromising objective: to deliver investigative work grounded in verifiable evidence, professional discretion and legal reliability.
From the outset, the firm was built to operate at the intersection of investigation, intelligence and litigation support, where accuracy matters, reputations are at stake, and findings must withstand scrutiny.

Andy Grudko
A Respected Voice in South African Investigation
Andy Grudko was widely recognised within the South African private investigation and security sector as a principled and disciplined investigator whose work helped shape professional standards over several decades.
His career encompassed private investigation practice in South Africa from 1980, preceded by security work in the United Kingdom.
He was a published author and thought leader, contributing books and articles on security-related subjects, and was frequently consulted within the industry for his insight into investigative methodology, technical countermeasures and ethical practice.
Andy’s approach was defined by a belief that investigative credibility is earned through methodical process, careful documentation and adherence to evidentiary standards, not assumption or conjecture.
These principles became foundational to the firm he co-founded and remain embedded in Grudko Associates’ investigative culture.
Andy Grudko passed away in 2025. His legacy continues through the firm’s enduring commitment to integrity, independence and the delivery of court-ready, defensible evidence.
