Thanks! We build as much in-house as possible. We've found that this is the only way to really build an excellent end-user experience without putting any of the burden on the user. Regarding sales, we've found that the most useful thing has just been putting the product in people's hands and demonstrating that it gives upfront value. The hard part with memory is that most of the value comes with compounding, so we've had to get creative with how we can show in 5 minutes how Hyper lets you do things you couldn't do before.
