JE Horizon LLC is a small holding company that designs, ships, and operates a focused portfolio of independently-developed software products. We don't raise venture money. We don't borrow foundation models. We ship things our own customers actually use.
We work on one product at a time until it has its own oxygen. These are the two we're actively shipping today. New products only get added here when they have real users, real revenue, or a real public beta.
An autonomous AI stock-options trader that runs entirely on the user's CPU. Built from scratch on our own data and tokenizer — no borrowed foundation weights.
Lead recovery for small business. Details coming as the public beta gets closer; placeholder live with a waitlist.
A small set of rules we apply to every product the company ships. Each one is a constraint we picked on purpose.
The code, the model weights, the data, and the audit trail belong to us — and to the people who run it. No remote inference for IP-sensitive workloads, no borrowed foundation models for core decisions.
If it can't run on a laptop without a GPU, we redesign until it can. CPU-first isn't a feature; it's a constraint we use to keep the architecture honest.
We publish the framing, the eval discipline, the failure writeups. We don't publish thresholds, training tricks, or anything that would let a competitor clone a year of work in a weekend.
Every decision a product makes is gated by a deterministic verifier — a function, not another model. The verifier can't drift. Models learn what the verifier will accept.
We collect what's needed to fix bugs and improve the product. We don't sell data, we don't profile users, and trade payloads / customer records never leave the operator's machine.
We don't run five half-finished things in parallel. Each product gets a focused build cycle until it has its own users, then it operates on its own air.
I started JE Horizon because I was tired of two extremes: products built on someone else's stack that can be killed with one API change, and products that look like AI but are actually a thin wrapper around a hosted model. There had to be a middle ground — software that the people who use it actually own, software that keeps working when the API you don't control changes its mind. So we build that. One product at a time, on hardware our customers already have, with a public devlog that doesn't give away the recipe.
