“With AI you're not just sending users into a few buckets — you can actually create almost an in of one experience for every individual user based off of their unique responses to these questions.”

Hyperpersonalization: AI turns onboarding quiz data into an N-of-one product experience

Where apps once bucketed users into 3-5 personas, AI now enables genuinely individual experiences.

He also notes a secondary benefit — onboarding quiz data collected for personalization is invaluable for optimizing paid marketing spend in web-to-app flows.
