One · Our story

Big things can start small.

McK & Jack is a family-built brand led by young entrepreneurs McKenzie (8) and Jackson (5) — better known as The Boss and The Genius.

What began with a lemonade stand has grown into community events, school visits, books, and more — McKenzie and Jackson learning firsthand what it takes to build something real.

When life gives you lemons, start a business with your children.
