About Roger Hill
Roger Hill is the founder and CEO of Hillstrong Group Security, based in Atlanta, Georgia. He created Resilion.io, an AI-powered SaaS platform that helps CISOs run operational technology (OT) cybersecurity programs across industrial sites. Hillstrong's own site describes him as bringing 30 years of OT cybersecurity expertise to global manufacturers.
Public directory listings show earlier roles at Siemens, Rockwell Automation and Kudelski Security, where he was a global senior director of OT security from 2022 to 2024. His profile also mentions work at GE and Fortinet. These listings are secondary sources, so check titles and dates on his LinkedIn page. He is described as a patent-holding innovator in industrial control systems.
Hillstrong launched Resilion.io publicly on July 15, 2025. Crunchbase lists Hill as one of four founders, alongside Cara Pritchard, Charles Tommey and William Noto. It records two companies founded by him.
Crunchbase shows one investment, one portfolio company, no lead investments and no exits. The investment appears to be Hillstrong Group Security, the company he founded, which Crunchbase labels as seed stage. No year, amount or other angel deals are public. He does not appear to publish an angel investing thesis.
No AI investments outside Hillstrong are public. Resilion.io is an AI product: it reads a customer's standards, policies and audit findings to baseline security maturity and identify gaps, and then helps teams carry out the program.
Hill has not published a stage, sector, geography or check size for angel investing. His operating focus is OT and industrial cybersecurity, governance, risk and compliance, and AI for manufacturers, utilities and critical infrastructure. Founders in those areas may find his experience relevant. That is a reading of his background and not a stated investment thesis.
