@ericbahn What's the brand of minivan?

@Hadley Gavin Nelson who re vibe coded holograph so he doesn't need to hear some BS like "The audio is working. You could use that."

[Si Zhang @RonghanZhang]

@raphaelschaad You absolutely got a point. I wouldn't trust any 2C product whose UI is like this.

[Si Zhang @RonghanZhang]

@ColinGardiner I would add secondhand marketplaces too. It’s an old category, but AI changes the product enough that it may be worth rebuilding from the ground up. AI can remove a lot of the friction around listing, discovery, trust, and most importantly, coordinating the transaction.

@kimmaicutler Because you will never be able to find cats that won't destroy your new couch, lol.

[Si Zhang @RonghanZhang]

omg...lol. You deserve to be proud of this. Our youngest couldn't sit tight for more than 1 hour before 3yo, or would start crying. We trained him a little bit before going to airport. And he actually enjoyed being out of airplane because he likes watching plane taking off and landing.

[Si Zhang @RonghanZhang]

@raphaelschaad @jenny_wen We wait until our youngest turned 3, lol.

[Si Zhang @RonghanZhang]

We’re enabling transactions that usually never happen:

* Large furniture that sellers would otherwise throw away because buyers don’t have a truck.
* Busy students who skip buying used because transportation is too difficult.
* First-time buyers and sellers who avoid local marketplaces because they don’t trust strangers.

@andrewchen Paper fireworks compass printing, lol. How did you find these?

@raphaelschaad @ycombinator Hello Raphael, can you please check DM? We just submitted application to YC.

[Si Zhang @RonghanZhang]

Yes, that's what we did in this summer for our secondhand marketplace, too. We found some unexpected behavior of our users, which is they shared the link showing their identify and trust score across platforms/groups such as WhatsApp, WeChat, Discord, etc. because they know where to find most potential buyers. So we optimized our sharing card and experience.

[Si Zhang @RonghanZhang]

@garrytan He is so proud.
