Practice for Your YC Interviews with Betafi
Hi folks, Betafi is a product feedback platform build around moderated user interviews and usability testing sessions. To help folks applying for the W23 batch with interviews coming up this week, we just launched a project templates feature and catered onboarding for fellow founders to practice and conduct mock YC interviews with each other. You can use Betafi's interview script feature, "instant tags," and timestamped notes to take turns annotating rough spots and practicing rapid-fire responses to questions with your cofounder(s), to try and make the most out of those 10 minutes during…

In the maker’s words, at launch
Hi folks, Betafi is a product feedback platform build around moderated user interviews and usability testing sessions. To help folks applying for the W23 batch with interviews coming up this week, we just launched a project templates feature and catered onboarding for fellow founders to practice and conduct mock YC interviews with each other. You can use Betafi's interview script feature, "instant tags," and timestamped notes to take turns annotating rough spots and practicing rapid-fire responses to questions with your cofounder(s), to try and make the most out of those 10 minutes during your real YC interview. A big part of the joy of building Betafi is getting to support other early-stage founders who wind up using our product in interesting and creative ways. This project came out of several teams applying to the W23 batch, who organically started using Betafi to help prepare for their interviews, so we thought we might as well build "first class" support for it! Do let us know what you think, keen to hear your feedback, especially given this is a slightly different use-case from what we initially designed the product for!

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
