# About

## The name

General System Dynamics takes its name from *system dynamics* — the discipline of modeling how complex systems behave over time — and from its founder's lifelong passion for systems theory, the field in which he earned his master's degree. The company's first published research put that training to work: system dynamics simulations modeling media consumption and cost in enterprise backup environments, presented at the Storage Decisions conferences in Chicago, Toronto, New York, and San Francisco. That habit of thinking — model the whole system, not the isolated part — has shaped everything the company has built since.

## The history

Founded in Chicago in 2008, General System Dynamics spent its first decade in enterprise data storage: Data Manager™, a platform for executing legal holds against backup data for eDiscovery, and Storage Forecaster, a modeling tool for storage capacity planning. Alongside the products came a body of published work — white papers, CIO guidance on legal holds, and features in Processor Magazine, Dell TechPageOne, and the InfoSec Institute — preserved in the [Insights archive](https://gsysd.com/insights).

## Today

Today General System Dynamics is Brian Greenberg's technology leadership and security practice: cybersecurity and risk governance, responsible AI adoption, data protection, and IT strategy. Fractional and interim CIO, CTO, and CISO engagements are delivered through Fortium Partners, where Brian is a Senior Partner. See [Services](https://gsysd.com/services).

When the problem calls for software, the company writes it: apps for Apple platforms, web and cloud applications, and open-source tooling for AI-assisted engineering, including the Apache-2.0 [Senior Engineering Partner](https://github.com/bjgreenberg/senior-engineering-partner) skill, an engineering-discipline framework for AI coding agents. The apps are small, focused, and private: data stays on your device or in your own iCloud, with no analytics and no tracking. See the [Software page](https://gsysd.com/software).

## Leadership

General System Dynamics was founded by [Brian Greenberg](https://linkedin.com/in/bjgreenberg), a technology executive and engineer whose work spans data storage, security, and IT strategy. He is a fractional and interim CIO, CTO, and CISO, a Senior Partner at Fortium Partners, and an adjunct professor at DePaul University, where he teaches cybersecurity.
