Nathaniel Golyan
Founder, ModelSide LLC · New York, New York
Nat is a hardware-native engineer. He fixed pagers for fun in grade school and built his first PC before high school. He grew up around his grandparents' electronics repair shop. As a teen he digitized his family's medical practice. That is where he first saw how much of an office's day goes into paperwork. Since then he has built more than 30 performance rigs and run GPU mining farms. When he specs a workstation, it is built from current parts you can buy in a store today, so upgrades and replacements are easy to find.
What we build and how we work
He has done this work for clients since 2024 and founded ModelSide LLC in 2025. We build AI workstations. A typical spec is an NVIDIA RTX 5090, 128 GB of RAM, a top-tier CPU and fast NVMe storage, running Windows. We install open-source models on them and add ModelSide Chat, a private ChatGPT-style assistant that runs entirely on your machine. We build document tools that search, summarize, extract and draft from your PDFs, scans, emails and records. We automate intake, follow-ups and other repetitive office work, and we build lead-generation and outreach systems. For offices with an IT team, we deploy open-source models privately on your own servers or in your VPC. If you already have a capable PC, we install on that instead. All of it runs on hardware you own, and none of it sends your files to ModelSide or any cloud.
It starts with a free 20-minute call. If a local setup fits, we write a fixed-price scope for the build; if it does not, we say so. The tools work with the PDFs, Word files, scans, email and spreadsheets you already use. Any direct integration is scoped per project. Support after delivery is optional, remote or on-site, with no hourly billing. We reply within one business day, and the person who answers is the person who built your machine.

- 2 AI workstations built and delivered to clients.
