Trades are durable in the AI economy

The trades and things that interface with the real world, in particular, in ways that are hard to automate, are very durable. OpenAI put out a paper, I think, with ChatGPT-4 that came out about sort of the jobs most at risk and least at risk. And the least at risk was, like, filled with home service jobs. It was, like, oil and gas jobs and, thumbtack jobs, like, things that you gotta be there.

AI automates administrative work for service professionals

Well, I think the magic is that the AI can do the digital interface for these folks in a in a much better way than they've ever done for themselves. Have your website and your social media presences up to date, respond to people quickly, answer questions, submit follow ups, submit estimates. Basically, the, like, admin work that's involved, which is rarely why these people got into the business.

Trust and word-of-mouth dominate home services

Broad marketplaces beat narrow vertical competitors

We actually, by being broad, could invest in liquidity building mechanisms that no narrow vertical ever could.

Even though the experience on the front end may have been less customized, the fulfillment capabilities and the marketplace experience was vastly better.

Home services is a trillion-dollar offline market

Sometimes you'll hear me say a trillion. I just wanna use the t. You know? And from what I understand, like, still less than 10% of it is booked online. It's the same homeowner, it's the same set of thumbs that uses Uber and DoorDash and Airbnb and Amazon. So the laziness and the desire to do things easily and quickly is there, but the purchase is mediated by certainty.
