Our Story
I’m Nathaniel Golyan. As a kid in my grandparents’ electronics shop, I spent weekends tearing down broken pagers and bringing them back to life. By elementary school I’d built my first PC, and code felt like the biggest puzzle I could solve.
In middle school I helped digitize my family’s medical practice; in high school I built 30+ high-end gaming rigs and ran GPU mining farms.
Today, finishing my degree in the era of AI, I’m combining deep hardware experience with software to deliver custom, local AI—so your critical data and workflows stay in your environment, under your control.
Team

Nathaniel Golyan — Founder & Builder
Hardware-native engineer focused on private LLM systems. Built 30+ performance rigs, GPU mining farms, and workflow-first AI pipelines for regulated teams. Obsessed with practicality, latency, and keeping data in-house.
Fixes pagers for fun since grade school. Built way too many gaming rigs. Now turns that obsession into private LLM setups that live in your office—fast, practical, and actually useful.
Why Local Matters
- Data never leaves your environment (privacy & compliance)
- Lower latency + predictable costs at scale
- Custom pipelines that mirror your real workflows
