My interview with Alex Grant, the Founder of Magrathea. His company has achieved a breakthrough in refining brines and seawater to create metals and rare earth materials. Magrathea has just signed an agreement with Tetra Industries in Arkansas to create a new US Magnesium supply from one of their bromine brines. This is a HUGE deal, not only a more sustainable way to make metal, but also reshoring a critical industry that we have outsourced to Russia and China. I'm a proud investor in Magrathea through my VC firm HyperGuap, and think this is one of the coolest startups to watch right now. Thanks for coming on the show Alex! This company should be on every tech nerds radar :)

![First Tesla Robotaxi Ride 🤠⚡ [RAW FOOTAGE]](https://i.ytimg.com/vi/ayx2g934NO0/mqdefault.jpg "First Tesla Robotaxi Ride 🤠⚡ [RAW FOOTAGE]
After getting access to Teslas new Robotaxi app last night, I immediately bought plane tickets and flew to Texas. This moment has been almost a decade in the making for Tesla who first announced Autopilot features in 2015. Of course I had to film my full first ride and upload the footage for yall! Austin legend/my friend Anuarbek stopped by for the first ride which made it even more epic (President of Austin Tesla Owners Club and Teslageeks Podcast). Im going to be in Austin all week riding and making videos. Let me know what you want to see and think! This was recorded 30 minutes after I touched down around 6PM on June 23rd, 2025.
The Robotaxi business could be a gamechanger for Tesla stock if it scales quickly. This is going to be something to follow closely. Im honored to be one of the early beta testers, huge shoutout to Tesla!!
