We had around 10 people testing the product before launching on Product Hunt. So, this was our public release.
Around 1500 users visited the website in a couple of days. We were the third product of the day on PH. We got 300 sign-ups during that week.
There were a significant number of users who were signing up from their personal gmail account instead of their work accounts. We had anticipated this, mostly because of privacy concerns. Our welcome email provided some assurance but don't think the strategy worked.
