As a Startup founder, marketing is one of the biggest topics you have to take care of. There are tons of marketing automation tools, and most of them aren’t cheap. I found several open source social media management tools, of which some of them are getting used by me for multiple years now. Socioboard Socioboard is your full-blown social media management tool. It is open source and offers all the features you know from paid tools like Buffer, Hootsuite and others.
