What is retention for startups?
Retention measures how well your startup keeps customers coming back and getting value over time. In this SparkLaunch Let's Learn episode, we break down what retention means, why it matters, and why it is one of the clearest signals that you are solving a real problem.
If people leave after the first week or month, growth gets expensive fast. Strong retention can improve revenue, lower pressure on marketing, and give founders a better view into whether people actually want what they are building.
