Forty years building enterprise technology — from the earliest database platforms through modern cloud-native architectures. Founder, operator, and trusted advisor to organizations where technology decisions carry real consequences.
"Forty years of real delivery — not theory. Every recommendation comes from having built it, broken it, and fixed it."
Andrew R. Treacy is a veteran technology executive and founder with over four decades of hands-on experience spanning software development, database architecture, systems integration, and technology consulting. He has built and led technology companies from the ground up — founding nine ventures across consulting, web development, mobile electronics, healthcare MIS, and enterprise data platforms.
His delivery record spans Fortune 500 clients across aerospace, defense, energy, manufacturing, finance, healthcare, and media — including Boeing, NASA, Raytheon, John Deere, Whirlpool, Fleet Bank, Hearst Publishing, and Best Buy. From legacy database platforms of the 1980s through modern AWS-native cloud architectures and iOS development, Andrew brings rare full-stack depth grounded entirely in production delivery experience.
