Lizard Optimization is a way to gain deep understanding of underserved customers by mixing exploratory testing, observability and product experimentation. This talk is a quick overview of the Lizard Optimization process, with a case study of a product where it helped unlock 500 times (not percent) growth year-on-year.  Learn how to steer your product growth gently without overcomplicating delivery and focusing on value, and how cheap and dirty observability can provide the necessary information to make informed decisions, understand your audience better and improve your products.
