How I work with you.

Pick the engagement that fits — or book a call and I'll tell you.

AI Kickstart

1 Week · Fixed Fee

Audit your workflows, find the highest-impact AI opportunity, and build the first one. You walk away with something working and a prioritized roadmap.

Best for: You know AI matters but don't know where to start. You want a quick win and a plan in one week.

Start a 1-Week Sprint east

Fractional Co-Founder

~8 Hrs/Wk · Monthly Retainer

Product meetings, AI integrations, team training, roadmap gut-checks. The experienced technical co-founder you can't justify hiring full-time.

Best for: You need ongoing technical leadership. Your team needs a senior voice in the room every week.

Explore a Partnership east

Product Sprint

Scoped · Fixed Price

Scope it tight, build it fast, ship in weeks. New features, internal tools, workflow rebuilds.

Best for: You have a specific feature, tool, or rebuild that needs to ship fast with senior oversight.

Scope a Project east

Custom Engagement

Flexible · Scoped Together

Every company is different. Tech audits, architecture reviews, due diligence prep, hiring support, one-off deep dives — if it doesn't fit above, I'll scope something that does.

Best for: You have a specific technical challenge or need that doesn't fit a standard engagement model.

Let's Figure It Out east

No decks. No frameworks. No long-term contracts. If I'm not adding obvious value, fire me.

You might be wondering.

“Can someone who's only here 8 hours a week actually move the needle?”

Yes — because the job isn't writing code. It's making the 3-4 high-leverage decisions per week that determine whether your product succeeds or wastes 6 months. A focused CTO for 8 hours beats an unfocused one for 40. I've been doing this for 15 years across 50+ products. I pattern-match fast.

“How is this different from a consultant who gives me a strategy deck?”

I don't give decks. I sit in your product meetings, review your PRs, pair with your engineers, and build things. If the AI strategy says "build an internal tool to automate lead qualification" — I'm the one scoping it, architecting it, and making sure it ships. You get a co-founder in the room, not a PowerPoint.

“What does this actually cost?”

A fraction of a full-time CTO hire. The AI Kickstart is a fixed project fee for one week. The Fractional Co-Founder is a monthly retainer. Both cost significantly less than a $300K+ full-time salary. Book a call and I'll give you exact numbers for your situation.

“I've been burned by contractors before.”

I hear this a lot. The difference: I'm not a contractor you hand a spec to and hope for the best. I help define the spec, challenge bad assumptions, and own the outcome with you. No long-term contracts either — if I'm not adding obvious value, you can walk away anytime.
