The person behind the work
Forty years. One thread.
In 1984, before "quant" was a job title, I co-founded Navigator Fund — a multimanager futures fund that landed in the Wall Street Journal's top ten. Around the same time I built RAMCAP, one of the first desktop investment optimizers, spanning 230+ asset classes. It sold in 1987 and is still in use.
In 1994 I built InfoHiway — a distributed search engine with 1.3 million visitors by March 1995. Formally incorporated as Infohiway Inc. in 1996, it featured "Fuzzy Relational Links" years before the concept went mainstream. RMI.net acquired it in 1998. The same fuzzy-logic instinct runs through everything I've built since.
I also hold a Master of Divinity. I've spent as much time thinking about consciousness and meaning as I have about markets and algorithms. Those aren't separate interests — they're the same curiosity aimed at different domains.
Today I run Yodacom — a research, development and consulting company pulling on the latest in finance and AI to help launch great products and personalities, serving financial advisors, events, non-profits, and local businesses. I live in Silverthorne, Colorado. I'm always building.

Introducing Presigate: The Pre-Flight Decision Gate for AI Agents
Autonomous AI agents can now spend your money, close your trades, and trigger your workflows. We built Presigate because none of them had a reliable way to check whether conditions were right before they acted.
The Modern Market Has Changed. Have Your Strategies?
I stopped trying to predict markets and started building systems that respond to them. What five technology cycles taught me about the difference.
