What's the most fun part of launching a new product?

We just launched our app Daily Hellos on PH and it's been such a fun process (https://www.producthunt.com/posts/daily-hellos). We are a small team, just like many of you here, so we had to handle everything and everything. Launch was somewhat stressful but very exciting. For me the most fun part was reading feedback about the app from people I had never met before! What about you?
