AI-powered growth. Personally built.

Strategy / Software / Execution

Agencies hand you advice.I hand you a running machine.

You have a business to grow. I build the systems that move it forward — custom apps, revenue engines, and AI that handles the follow-through. Then I keep them running.

One senior operator. From first idea to daily operation.

01 / What I build

More capability.
Less on your plate.

For founders and small organizations ready to turn a good idea into a working business system.

The flagship / Managed AI

Your AI Chief of Staff.

An AI operations agent that works inside your business, in your accounts, under your rules. I set it up, manage it, and keep it working for you.

  • Keep track of the money and moving parts.
  • Stay on top of leads and follow-ups.
  • Turn scattered tasks into action.
  • Report back to you. Stay under your control.
02 / Custom builds

Your next revenue stream.
Built from the ground up.

Membership platforms. Online stores. Client portals. Launch funnels. Custom apps. I connect the strategy, the software, and the marketing — and run the system after launch.

03 / Fractional CTO & CMO

Senior leadership.
Hands on the controls.

A website that needs to work harder. An enrollment push. Ads, automation, or an entire marketing operation. Get technical and marketing leadership from the person doing the work.

03 / How I work

Small team.
Short distance
to done.

You work directly with me. A tight production team and AI help me move the work forward.

Find the move that matters.

We start with your business: what's stuck, where the opportunity is, and what needs to happen next. The goal sets the scope.

Put something real in your hands.

I design and build the system. You see working software early, then we sharpen it with real use and feedback.

Keep it earning its place.

I stay involved after launch. AI handles the volume and follow-through. Strategy, judgment, and accountability stay with me.

Meet your builder

Josh Rosenfeld.
Still making things.

Apple was my first agency client in 1995. ShowingTime and Zillow came later. I went all-in on AI in 2022. The tools have changed. My job is still to turn a good idea into something people can use.

I'm a founder, a builder, and an educator. I'm also neurodivergent, and I care about making technology useful to people who are often overlooked. That care goes into everything I build — including your business.
