Leads go cold
Kardinal CRM keeps every contact, deal and reply in one place, with follow-ups that stop on their own when someone replies.

I build advanced web-app programs, executive software suites and bespoke custom programs, and I do advanced AI consulting. If something won't earn its keep, I'll tell you before you spend a dollar.

Ways to meet
Pick your way to talk.
Each option opens my live calendar right here. You pick the time and it lands on my calendar. Or send a 1Request and we'll work out the time by text.
How I work
No fluff. No runaround.
- Prices go on the page. Software and Kardinal prices are posted. Custom work gets a written quote before you pay a dollar.
- You see it before you pay. Our software comes with a free 7-day demo with no card. Kardinal CRM has a 14-day trial.
- Money in, or time back. If what you want won't bring in revenue or save you hours, I'll say so and we skip it.
- You own your data. Our offline apps keep your data on your own computer, and Kardinal CRM exports everything, any time.
The ROI part
Where the money leaks. What we plug it with.
Your people are invisible online
Kardinal for teams gives everyone their own page with one-tap call, text and Save to Contacts, all run from one admin.
Quotes take all week
ROI Airstrike measures, prices, proposes and tracks every job from one app that works offline.
Your customers forget you
Send a push notification to everyone who saved your app, so it shows up on their phone like any app update.
Paperwork eats the day
Apps built for one kind of work: real estate, title, law, IT, solar, farms. Each one has a free 7-day demo.
Something nobody sells yet
Tell me what you'd want built. That's the reason most of what's on this page exists.
