A presidents game that makes U.S. history stick. Right answers train your fighter, what you learn about each president tells you how to beat them, and every win goes in your binder.

The Monthly Mission
"We learn by building and shipping. Every 30 days, we take an idea from zero to something real and live. What’s the value? Can we build it? What should it look like? Could it make money... and does that even matter? Then we decide: keep going or move on to the next idea."
Joel, Cassandra, and the monsters.
About us
We’re the Pettigrews. Cassandra, me (Joel), and four kids we call the monsters. We lived in Florida for years and moved to Colorado last year for a new job. We miss Disney and the beaches, but we have loved the mountains.
I’m a product manager that has mostly focused on Data, Analytics, and UX. At home I like to experiment and build things, mostly because I want the kids to grow up that way: ask the question, go find out, build the thing yourself. Cassandra recently went back and finished a degree in software development while raising four kids, so this is genuinely something we are all involved in.
