Y Combinator Startup Podcast · How To Better Understand Your Users · 9 Jul 2026 podcast

Dave, I'm one of the users.

And every other user of your product gets their own row.

And then every column represents a time period.

I think days are usually the right thing to use for your product, but it probably depends a bit on the nature of your product.

So let's just draw in the days.

I'll just do Monday, Tuesday, Wednesday, Thursday, Friday.

And you can make this as big or as small as you want.

For the sake of this example, I'll just do like a week or two of days just to show you what's going on here.

And then the idea, it's called a dot plot, is you put some dots in each of the cells.

You want to pick an event that your user does in the process of using your product that you think represents value in the product.

Maybe it's sharing a photo if you're building a photo app, or listening to a song if you're building a music app, or processing an invoice if you're building a B2B invoice processing product.

And you can just put a dot for each day that each user uses the product.

Let's say we're Spotify and we're building a music streaming app and we want to see how our users are using it.

Let's pick the event that we're going to chart here being listen to a song.

So anytime a user listens to a song during a day, we're going to put a dot.

So for me, let's say I...

listen to Spotify song on Monday and Tuesday and not on Wednesday, but Thursday and Friday again, and then maybe again on Monday and Wednesday.

Another thing you can do to make a record of the first day that a user used the product, the day that they onboarded, you can put another symbol.

Like let's say on a user's first day, we'll just draw a little ring around the dot like that just to give us a little bit more signal.

And what you'll eventually start seeing
