Nexum isn't a startup pitch. It's a system that manages a real household, built by a family that got tired of giving their data to corporations.
We're not a team of ex-FAANG engineers who saw a market opportunity. We're a family — with kids, a mortgage, a vacuum robot, a few cameras outside, and a deeply held belief that the smart home industry is selling convenience at the price of privacy.
The original system was a Raspberry Pi running a stock tracker and a Ring camera feed. It wasn't pretty. But it was ours — running in our house, on our hardware, showing our data to nobody.
Nexum grew from that first prototype into a full home intelligence platform: FastAPI backend, React dashboard, AI agents, real-time markets, device control, security scanning, and a multi-user family system. All running on a cluster of small computers that fits in a closet.
LUDDAN SERVICES LLC was formed to formalize this work — to build it into something that could serve other families who want the same thing we wanted: a home that's smart on your terms.
Fleet coordinator by day. Builder by night. Designed the Nexum architecture, hardware stack, and product vision. Studying Series 65 (Investment Advisor). Obsessed with local-first technology.
Nexum's AI core. Handles natural language device control, portfolio analysis, security scanning, research tasks, and daily briefings. Powered by Claude — runs locally within the home network.
Continuous scanner running every 15 minutes across all nodes. Checks open ports, SSH hardening, fail2ban, log integrity, authorized keys, and PostgreSQL exposure. Alerts via Telegram on any regression.
Monitors markets, news, Telegram signals, job trends, and ShopGoodwill deals. Synthesizes findings into morning briefs, trade ideas, and opportunity alerts. Runs on a schedule and on-demand.
Your home data belongs to you. Not to a platform, not to an advertiser, not to a terms-of-service agreement that changes next quarter.
A $150 single-board computer running your home is more reliable, faster, and cheaper long-term than a subscription to someone else's infrastructure.
Not just the person who set it up. Nexum is multi-user by design, with profiles and permissions that make sense for how real families live.
We integrate with whatever you have — Ring, Tuya, Alexa, Narwal, Vizio, Honeywell — because lock-in benefits the platform, not the homeowner.
Continuous automated security scanning, TOTP 2FA, SSH hardening, and zero exposed ports. We eat our own dog food — this runs in our home.
Markets, portfolio tracking, prediction markets, trade journaling — your home dashboard should be as useful for building wealth as it is for turning off the lights.
