Lama

The Lama app provides everything you need for professional branding.
The video "Question and Answer" app allows you to network with experts in almost any niche.
The service also provides professional journalists to interview each user in order to gain publicity for their current startups and projects.
The journalist are from publications like the Economist and other respected organizations.
The interviews from prominent journalist lends credibility for new companies and brands which are trying to gain more exposure and provides interesting content for social media outlets as well as websites.
In my opinion, the ability to instantly project expert status and credibility in one's niche is the greatest feature of the app.
