What a founder can learn
Founder takeaway
A polished product can still fail to become a habit. For agent products, design for repeated use in real workflows—not just an impressive first experience.
Why it matters
If users forget to return, product quality and novelty will not translate into retention. The product must earn a clear, recurring role in the customer’s routine.
Put it to work
Ask: What specific trigger should remind users to invoke our product, and how can we embed that trigger into a workflow they already repeat?
