FREE THE SMART SIMPLE BUSINESS STARTER HUB

Turn that idea into something you can sell.

Learn to build a small, useful product with AI. Then get it in front of the people who might buy it.

I'll show you how I approach both, with my complete build guide, five build videos and the traffic lessons inside my free Starter Hub.

Take a look inside

FROM MY OWN WORKBENCH

Actual projects you'll find inside.

BUILT & SOLD

A warehouse needed a better way to track stock.

That became a small inventory app for a real business. A specific problem gave the project a reason to exist.

Inside the hub, I share this build alongside the tools I'm developing for my own work.

A NOTE FROM KRESO

I've spent plenty of time building things that went nowhere.

Kresimir KlukovicFounder, Smart Simple Business

I've been working online since 1999, through websites, traffic businesses, affiliate offers and now apps. Some projects sold. Others taught me where I was wasting my time.

One attempt: 400 cold emails, three interested replies and zero sales. Those numbers alone couldn't tell me whether the offer, the audience or my follow-up was the problem.

That's the work I want to share here. How I choose what to build, what I try to sell and what happens when I put it in front of people.

I made the Starter Hub free so you can look at the work and try the approach for yourself. If you later want a structured implementation course or personal help, those options are there.
