[00:37:43] S1: Mhmm. [00:37:43] S0: Domino's was the first to have done this at the time, and we thought that would that would make a bunch of sense. And I was just like, how am I supposed to convince the delivery driver who doesn't have a relationship with us to download this app from Grubhub to actually turn it on to create, you know, anxiety for the consumer of, like, they maybe didn't take the right turn or whatever? I was like, I don't think this makes sense. No one's gonna use it. And, you know, Mike and Matt, like, overruled me and and pushed us to do it. And in the long run, it ended up being quite necessary because of the innovations around DoorDash and Postmates and and later Uber Eats into having their own delivery network and and us needing to counter that, that's, of course, a key piece of technology that needs to lever... Have parity with those new services. So that was an area where perhaps they were thinking a little bit more longer term than I was. And, you know, I was not able to kinda get where they were going on on the longer term time horizon of of how this would be actually ultimately adopted and useful. [00:38:38] S1: This is an awesome segue to the next area. But real quick, how did they get drivers to start using this app? Was there anything really clever they did?

[00:38:45] S0: I I think it was fairly low adoption for a while and leveraging, basically, restaurant authority. So if we were able to push on our restaurant customers effectively to say, like, hey. If you use this, it'll get you more orders. We'll get you prominence in the the UI, things like that, to then push down, you know, to their direct relationships with the drivers to get them to adopt.

Okay. So shifting to our last topic that I was excited to chat about is around network effects and marketplaces and SaaS and kind of how those things connect. I feel like you have the clearest way of thinking about and explaining network effects. So maybe just to start, can you just, like, simply explain what is a network effect and then the different types of network effects that exist?
00:40:20 · Casey Winters
[00:40:20] S0: Yeah. No pressure after you say that. Right? Yeah. So at its core, a network effect is when a product or a business gets better with more users or customers using it. And there's three types that I tend to focus on. So the first and probably the most well known is called direct network effects, and that's when every additional user makes the product better for all the existing users. So when someone joins WhatsApp, other people can talk to them that they... That wouldn't be able to talk to them before, and that makes WhatsApp valuable... More valuable for everyone. And then there are cross side network effects where there's two distinct types of users, and adding an additional user on one side of the network makes it more valuable for all the types of users on the other side of the network and vice versa. So when a restaurant joins Grubhub, it creates more selection for users to order food. And when more users start ordering more food, Grubhub becomes more attractive for restaurants to join so they can make more money from, you know, delivery orders. The the last network effect I focus on is data network effects. And that's when the quality or cost of something improves as more data is collected through the product. So when you save content to Pinterest, to a board, it gives Pinterest signal on the quality of that content, its relevance to other pieces of content since they're shared to the same board, and more signal on your preferences. And this allows Pinterest to better recommend more content to you as well as to other people who look like you and share similar interests. So, one thing that's tricky about these network effects is most people talk about network effects in the context of social network, not marketplaces or, you know, SaaS, like my background. And the thing that's really tricky in understanding social networks is they're traditionally described as these direct network effect businesses. But all of them have to become either cross side and or data network effect businesses over time. The only companies that stay direct network effect businesses are these pure communication tools like Messenger, iMessage, WhatsApp, and there isn't a clear path to make money with those. But you wanna sell ads? You're becoming a cross side network effect business. And, also, creators versus consumers creates a cross site network effect business.

If you wanna get better at personalization, guess what? You're recommending content by leveraging, you know, data network effects. [00:42:44] S1: I love that. No. You you nailed it. I imagine Marketplace founders listening to this may be wondering, hey. How do I... Can I add on these additional network effects? Can I evolve towards one of these? And what you're saying is not only can you, you need to eventually. [00:42:58] S0: I agree. Right? I think, you know, they're a great form of defensibility, first off. Off. So do they make sense for every business? No. But in a lot of cases, in order for you to evolve properly and continue to grow, they can become [00:43:09] S1: a necessity. Are there any other examples of Marketplace companies that come to mind that did a great job evolving or adding one of these network effects or just, like, interesting? [00:43:18] S0: Let's take some inventory. Right? So I think Zillow is really interesting in that a real estate listing site is not particularly an interesting product, but the ability of saying, very rarely do, you know, both sides of this network, people who are buying homes and selling homes, need to connect. But I can find a way for the brand to connect with both of them by giving real time pricing information on the value of homes. And that creates a much stickier product for both sides. I think that was a a pretty genuine, innovation, you know, that other people have tried and and rarely been successful with. So that's that's one that definitely, sticks with me, you know, off the top of my head. Great.

[00:44:05] S1: We've been talking about Grubhub a lot, and Grubhub had some pretty strong network effects and Yep. In large part thanks to the work you did. And one of the benefits of network effects is it creates a barrier to entry. It's hard to replicate and compete with a company where they already have all this network effect. But famously, Grubhub got disrupted by DoorDash and Uber Eats. And I need to talk about how that happened and why that happened. And it'd be cool to hear just, like, what do you think they could have done differently and what happened where their network effect got eaten eaten for lunch, pun intended?
