Albert Cheng: evaluation

5 Oct 2025 Lenny's Podcast How to find hidden growth opportunities in your product | Albert Cheng (Duolingo, Grammarly, Chess.com)

“One exception is that Grammarly was a different type of product and that you install it and you don't proactively open it every day.

One exception is that Grammarly was a different type of product and that you install it and you don't proactively open it every day. So that was interesting to me because I assumed that you should always just focus on existing user retention, but for a product like Grammarly, it's actually the activation installation aha moment that's really, really critical and will carry the user for a very, very long time. That makes sense. Yeah, the stats would show someone's a daily active user because they're typing things and that's not an accurate step for Grammarly. The other interesting trend I've noticed across successful consumer subscription products is they always start very scrappy and very cost-efficient and spend efficient because I think it's because it takes them a long time to find something that's working and they're surviving on that margin of retention to growth cost essentially.…
