It's already 2 years since I first posted StoryChief. We received some great feedback back then from content marketers here on Designernews. 2 years later a lot has changed in our product. We now cover all aspects a content marketers needs like blogs, social media, and employee advocacy. This all with collaboration in mind.
UX wise it's a big challenge (I love it) to fit all these features nicely inside our product. Very proud of what we are building and looking forward to your feedback!
