We've been devoting a lot of time to talking about software businesses in recent weeks.

One of the reasons we are so fascinated by them is that despite how difficult it can be to start one, these types of businesses can have tremendous upside.

Jordan Gal is the founder of CartHook, a software company that helps Shopify merchants present offers to shoppers at checkout.

Jordan first reached out to us back in 2015 with an investment opportunity (and we turned him down!).

It really shouldn't come as a surprise then that Carthook has grown exponentially in the years since, with its user base having made more than a billion dollars worth of sales.

Jordan joins us on today's podcast to share the story of CartHook.
