Internally we use Slack.
Co-founder & CEO - MuseFind
We could not live without Slack and use it for Customer Service. Our customers are entrepreneurs who are raising money, so when our customers join our community, we invite them to our Slack channel. We’ve created channels for bugs, geographical areas, brags, funding ideas, and everything you can think of that is both advice and customer service-related. There are 200+ women on there as we speak. There is mentoring and coaching and people can DM us about issues. It’s a very tight and active community of entrepreneurs!

We integrated Slack with Intercom and Stripe to get all of the notifications there. We also have our own Slack bot :)
