In a conversational interview, Speaker B explains why marketplace businesses remain compelling opportunities. Drawing on personal experience across many industries—from early work with oDesk/Upwork to later exposure to Stitch Fix, Airbnb, and Uber—he frames marketplaces as a unique bridge between the digital and physical worlds. He highlights education as an emerging marketplace vertical where universities match courses to students, and points out a significant gap between rapid AI advances and slower robotics progress. This gap leaves many everyday physical services—such as prepared‑food delivery, pet‑care (e.g., Rover), and ride‑hailing—still reliant on human providers, creating fertile ground for new marketplace platforms. Throughout, he emphasizes that while AI is transforming knowledge work, the need for two‑sided service marketplaces persists wherever physical interaction is required.

Are you seeing any specific opportunities maybe that you're excited about for marketplaces?
Yeah, it's sort of interesting, right? I think the opportunities haven't changed and it's kind of one thing I'm up close and personal with at Stanford is that what I always found exciting about, you know, that, so once I started working with oDesk and Upwork, that as many of you know, kind of led into the opportunity to work with a lot of different marketplaces. And if you look at my sort of LinkedIn profile, you'll see there wasn't really a lot of, you know, specificity in one vertical or another. I've actually had a chance to work with a wide range of industries over that time. And one of the reasons I find that really exciting is marketplaces as a tech business are sort of an interesting bridge between the digital world and the physical world. You know, Stitch Fix is retail, Airbnb is lodging, Uber is rides. And I continue to be fascinated by that bridge. And that's where I think marketplaces as businesses are really exciting. So another one that we didn't, you know, I haven't touched in my, in industrial work, but I have in my research work is education, where basically, you know, universities are marketplaces. We're matching courses with students. And of course, there's many marketplace platforms that are trying to do the same thing. I think that's a really interesting way to think about verticals for marketplaces because so much of the push in AI is away from that human physical interface. I think one of my colleagues, for example, has pointed out There's a big gap between robotics and AI right now. AI has just completely taken off. It's a massive steep vertical. Robotics has not advanced, you know, to the same degree. You can't go out and buy a $10 robot that's going to fold your laundry for you. That remains a very hard problem, right? But you can, you know, go interact with L1 and prove theorems that you couldn't prove yesterday. So why that gap? And well, that gap is super interesting because that gap means There's still this interface to the physical reality of sort of what humans deal with every day that's not being addressed. And I think every vertical I find interesting, you know, kind of falls in that space. I'm talking now to a company that's kind of working on food delivery, sort of prepared food delivery. You know, that's of course a super interesting space like that. I think other marketplaces, like we have a dog and, you know, there's obviously marketplaces like Rover and so on for Sort of pet support. So that's like another vertical like that, right? I think those are all so interesting because that remains a place where you need 2 sides. You really need somebody to provide that service on the opposite side. AI is not here yet to replace your dog walker, to replace your, you know, sort of food delivery, to replace the rides that you're getting. We're getting there on that last one, but, you know, not, I think there's so many ways in which we're not quite there yet. And I think that's how I think about the distinction right now.
