WHERE EXPERIMENTATION IS GOING (AND HOW TO GET THERE)

Summary from the TLDR Marketing newsletter

Experimentation is shifting from testing individual content to testing entire systems because AI has made variation cheap and abundant. Teams can now generate thousands of variants at low cost, so the bottleneck is no longer creation, but the infrastructure to evaluate and deploy them. Most companies remain stuck at basic A/B testing even though higher levels involve parameterized testing, automation, and self improving systems. Progress depends less on better tools and more on changing the organization's operating model, since feature-driven structures limit experimentation impact. Companies that align experimentation with decision making and decentralize ownership are more likely to advance and see meaningful gains.
