For example, one of the critical business model hypotheses they could test locally is Product/Market fit – the connection between their Value Proposition (what product or service they were building) and the Customer Segment (who they were building it for.)
Further refinement of Product/Market fit could be done locally by using Value Proposition Design.
But other critical hypotheses such as activities, resources, partners, channels needed testing offshore. For example, many of the Australian sports tech business models shared common elements. They intended to get scale for their business by growing in the U.S. while building their products in China. And their branding and demand creation activities were going to occur primarily outside of Australia. This meant they would need U.S. channel partners and Chinese manufacturers and customer acquisition and activation programs outside their home country. And as good as the Australian angel investors have been, there still is dearth of serious follow-on funding in Australia. This means that most follow-on rounds of tens of millions of dollars, if needed will likely come from outside the country.
