Four Doors

Work With Me

Most people start with a free call or the assessment. Everything else is what comes after.

No "tiers." No "programs." No 90-day discovery decks. Just four doors and what's behind each one.

Quick Answer

There are four ways to work with Justin McKelvey: a free 30-minute strategy call (fit check, no pitch), a 2-week AI Readiness Assessment (written roadmap, fixed fee), done-with-you AI builds (custom implementation, scoped per project), and ongoing fractional CTO engagements. Most clients start with the free call or the Assessment, then expand into builds or fractional work afterward.

Common Questions

How long does an engagement with Justin McKelvey take?
Engagements range from a free 30-minute call to ongoing fractional CTO retainers. The AI Readiness Assessment is fixed at two weeks. Build engagements typically run 4-12 weeks depending on scope. Fractional CTO is ongoing — most clients work with me for 6-18 months.
What does it cost to work with Justin McKelvey?
The 30-minute strategy call is free. The AI Readiness Assessment is a fixed fee (discussed on the call). Build engagements and fractional CTO work are scoped per project — most engagements land between $5K-$50K total. No hourly billing, no surprise invoices, no 6-month minimum contracts.
Do you sign NDAs?
Yes — happy to sign your standard NDA before kickoff on any engagement. I send a mutual one if you don't have your own. The 30-minute strategy call is informal and doesn't require an NDA unless you'd like one signed first.
Can I switch engagement types mid-stream?
Yes. Most engagements naturally evolve — a strategy call leads to an Assessment, an Assessment leads to a Build, a Build leads to ongoing fractional work. There's no contract lock-in. If something isn't working, we change it or end it without ceremony.
Are you available right now?
Booking depends on capacity. Strategy calls are usually available within 1-2 weeks. Assessment slots are capped at 2-3 per month, so 2-6 week lead time is typical. For fractional engagements, lead time is 2-4 weeks. Book a call to check current availability.
