David Markovich, founder of Online Geniuses discusses his platform, which connects the best minds in the digital marketing space with one another. Markovich founded the company via Skype, first connecting all of the "coolest," most accomplished people he knew into one place. The Skype chat soon grew to include hundreds, though, and he realized Slack would be a better platform. Online Geniuses also hosts events in various cities. In October, there will be one at New York's Javits Center. The group is free to join, but those who apply go through a vetting process. The company hosts events on Slack called "Ask Me Anything," in which major influencers and innovators like Gary Vaynerchuk speak to the community. Markovich notes that these major speakers voluntarily speak for free, as their way of "giving back" to their communities.
