Where I'm stuck, honestlyBuilding Gero was the easy part. Getting it into people's hands is harder: launch and marketing are my weakest skills right now, so I'm learning them in public. If you've taken an app to market, I'd love to buy you a coffee and ask a lot of questions.

Retail innovationI've been spending my evenings at retail innovation events and competitions, such as the Retail Innovation Competition (RIC), to see how stores, shoppers and data meet in real life.
