About Us

Built in a
real home.

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.

"The smartest home is the one that knows you and keeps your secrets."

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.

The team.
Small. Focused. Building from the inside out.

What we believe.
🔒

Privacy is non-negotiable

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.

Hardware you own beats cloud you rent

A $150 single-board computer running your home is more reliable, faster, and cheaper long-term than a subscription to someone else's infrastructure.

🏠

Home intelligence should serve the whole family

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.

🤝

Open beats walled

We integrate with whatever you have — Ring, Tuya, Alexa, Narwal, Vizio, Honeywell — because lock-in benefits the platform, not the homeowner.

🛡️

Security is a feature, not a checkbox

Continuous automated security scanning, TOTP 2FA, SSH hardening, and zero exposed ports. We eat our own dog food — this runs in our home.

📈

Wealth intelligence belongs at home too

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.
