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.
