Berthume Software is the software brand of Berthume Enterprises, LLC — an independent software company founded by Greg Berthume, a software architect with 40+ years of experience. Data Fortress is our product.
Berthume Enterprises, LLC is the company. Berthume Software is the software brand. Data Fortress is the product. Greg Berthume is the experienced founder and architect behind it.
Berthume Software is an independent, Texas-based software company. It isn't a venture-funded startup chasing growth metrics, and there's no layer of account managers standing between you and the product. It's a bootstrapped company run by an experienced professional whose priority is shipping quality tools that solve real problems at an honest price. When you email , you're writing to the person who designed and built the product.
Data Fortress was created to help individuals, professionals, families, and small organizations organize important information in a secure, flexible, and practical way — without being forced into complicated enterprise systems, scattered spreadsheets, or cloud-only subscription services.
After four decades of building custom software for businesses of every size, one pattern kept repeating: most small and mid-size organizations don't need a six-figure custom application. They don't need an ERP system. They don't even need a database developer. What they need is a structured, reliable place to manage their operational information — something more powerful than spreadsheets but less complex and less expensive than custom software.
Data Fortress fills that gap. It's the "in-between" layer — structured enough to replace the chaos of scattered spreadsheets and documents, flexible enough to adapt to how your business actually works, and affordable because there are no subscriptions, no recurring fees, and no vendor lock-in.
Every one of the 67+ template collections was designed from real industry knowledge — not by surveying templates on the internet, but by understanding how businesses in each sector actually operate, what records they keep, what relationships exist between those records, and what workflows matter most.
Greg Berthume is the founder and chief software architect of Berthume Software. With more than four decades in professional software development, he has designed, built, and shipped production systems across 10+ industries — wholesale distribution, law-firm accounting, payroll and tax filing, travel, retail, food broker/distribution/manufacturing, medical, education, and more — including a state-of-the-art email system engineered from the ground up.
He isn't a manager who used to write code. He is an active, hands-on architect who still ships production software, and that direct experience shapes every part of Data Fortress: each design decision, template structure, and user interaction comes from someone who has spent decades solving real business problems with software he built himself.
Data Fortress is built on a set of principles that come from decades of watching what works and what fails in business software:
Your information lives on your machine, in your files. No cloud dependency, no hostage situations, no "export fees." If you stop using Data Fortress tomorrow, your data is still yours.
You buy it once. You use it forever. Software shouldn't be a monthly bill that goes up every year while the vendor adds features you never asked for.
Every template, field, menu, and label can be changed by the user. No developer required. No support tickets. No waiting. If it doesn't fit your workflow, change it in minutes.
Start with one collection. Add more. Build your own templates from scratch. Combine collections. Activate advanced templates when you're ready. There is no forced upgrade path.
The current library of 67+ template collections spans industries from accounting and construction to veterinary practices and wedding planning — and it's actively expanding. New collections are designed and added regularly. Your $99 license includes all of them — install any or all, and new collections are included as they're released.
Every template collection is AI-generated using deep domain research — analyzing real industry workflows, regulatory requirements, and operational patterns to produce domain-informed starting points. This approach is what lets us include all 67+ collections at a fraction of traditional consulting costs.
Because each collection is a starting point, you have full control to add, modify, or delete any template, field, or menu. We provide software support for Data Fortress itself; template customization is in your hands. See the FAQ for details.
If none of the existing collections fit your needs, we'll build one that does. Contact us to discuss a custom collection designed specifically for your business, your workflows, and your terminology.
