We use JIRA for project management and have a serious love/hate relationship with it.
We use G-Suite because it's the best...calendars, e-mail, drive, docs, what else could a company want?
We use Plivo to support the text messaging function of our Helper web based application.
We use Sketch (alongside a bit of Adobe XD) for the majority of our UI design flow and for mockup creation.
Illustrator is used for our logos and to build a variety of small parts of our website and apps.
We use Google Analytics to monitor usage of our website and web application Helper.
