JustCall

We launched JustCall.io on Product Hunt on 2nd Dec 2016 and got our first paying customer in March 2017.

It took us 18 months to reach our 1st million ARR. 4 things worked well for us and helped us grow:

1. Integrations with CRMs and Helpdesks
2. 24 x 7 Customer Support
3. Revenue Expansion built in the revenue model (accounts expand either via increase in seats or by upgrading to premium plan)
4. SEO
