Has a website recently asked you to "prove that you're not a robot" by choosing all of the images that contain a traffic light? Congratulations, you've just helped Google train their artificial intelligence (AI) systems! Data-driven products are only as good as the data they're built on. And that data comes from ecosystems: early adopters, power users, hobbyists, and even people who have never heard of your product. In this session, we'll explore how to build and grow ecosystems around data-driven products. We'll discuss how to identify and engage key ecosystem participants, how to motivate and keep them coming back, and how to turn them into your product's biggest advocates
