A slightly mad labs portal for everything I’m building.
ARJ Labs is Alex Jefferson’s operator workshop — short-term rentals, property, AI systems, growth experiments, and the useful weird science that keeps real businesses running.
One lab bench. Multiple live experiments.
Each lane is real operating work — not slideware. Open the fronts that matter to you.
Port City Stays
Seacoast short-term rental management across NH, MA, and ME — guest experience, ops systems, and owner partnerships.
Double Diamond Stays
Growth Stack for independent vacation homes — pricing, multi-channel distribution, guest email, presentation, and social — with 56 Main Street in Ludlow as the case study.
Real Estate
Personal property and long-term rental work under RGA and related entities — practical ownership, not hype.
AI Lab
Always-on agents, second-brain systems, and multi-model routing for real businesses — Hermes and friends included.
Marketing & Growth
Brand, content, direct booking, local presence, and the guest journey — growth with taste.
Ops & Tools
Playbooks, automation, and tooling that keep operators sane. Build-in-public energy, private ops stay private.
Playful exterior. Slightly mad scientist core.
The clay globe look is the handshake. Under it: Seacoast hospitality ops, property ownership, and AI systems built like lab equipment — tested on real Tuesdays, not demos.
Built from live businesses, not theory posters.
Alex Jefferson runs hospitality companies and the AI lab gear around them.
Also known as Xander. Based on the New Hampshire Seacoast. Background in tourism planning (UNH), software/customer work, then full-time short-term rental operations and multi-entity property work.
ARJ Labs is the public lab door: one place to see the businesses, the systems practice, and how to collaborate — without dumping private ops onto a homepage.
