Forward, a futuristic doctor's office that charges a $150 monthly fee and doesn't take insurance, is expanding beyond San Francisco to Los Angeles, with plans to go nationwide.

Launched in January, Forward is the product of several dozen veterans of Google, Facebook, Uber, and Palantir, who got together to reinvent the doctor's office for the 21st century. Its flagship location in San Francisco looks like an Apple Store meets "Westworld," complete with state-of-the-art diagnostics tools and an AI system that listens and takes notes for doctors.

Forward has raised a reported $100 million from investors including Ashton Kutcher, Kevin Durant, Matthew McConaughey, Alphabet's Eric Schmidt, and Salesforce's Marc Benioff.

In addition to the new outpost in Los Angeles, Forward has launched a mobile doctor's office built on an 18-foot-long trailer bed. The truck is expected to roll through additional cities.

I toured Forward's location in San Francisco earlier this year. Here's what it was like.
