#125 The $350M Startup Creating Perfect Memory (Rewind.ai — CEO Dan Siroker)

Rewind.ai just raised their Series A at a valuation of $350M. Investors include Andreesen Horowitz, Reddit’s Alexis Ohanian and OpenAI’s Sam Altman. Rewind sits on your computer and phone, and watches everything you do. Then you can ask it questions like: What was that really great Mediterranean recipe I looked at last month? Or I’ve got a call with a client next week, can you summarise every interaction I’ve had with them? But here’s where it becomes even weirder, powerful. They’ve announced the Rewind Pendant, a small audio recorder that sits on your chest. Rewind will be able to listen in to every conversation you have. You can ask it: What birthday present should I get for my partner? Did they drop any hints? Or how many arguments did we have last year? Pretty Black Mirror, right? Once you get over the ick however, you realise that this is correcting a lagging human function. Just like the cursed amongst us wear glasses; tools like Rewind will repair our broken memories.
