Ask HN: What are the best ways to get first 100 users for a powerful Slack Bot?

Just revamped and launched Scribe, an In-Slack Sales Bot designed to help you focus and scale your meaningful sales conversations. Looking for ideas on how I can get a good handful of users to try it out?

Goes without saying, would really appreciate it if at least a few of you awesome folks check it out. The idea is to get as much criticism as possible and iterate/improve before we launch on PH(third week of July

All help/tips are much appreciated :)
