It's not for everyone clearly. When you actually spend more than a couple of weeks, you stop getting that need to discover and talk to people, and get to work super productively (one of the reason is: you can't wait to go back to enjoying the place). This solution works if you have a 100% online product, or if you opt to travel at the right stage for your startup (when you have had networked for now, when you're pivoting etc).
