OpenTable had a global chicken-and-egg problem where they needed restaurants on board to entice customers to use the site, but needed customers on the site to convince lots of restaurants that it was worthwhile.

Opzi's chicken-and-egg problem is broken down in to many smaller sub-problems. An individual Opzi is used by a single company or maybe even a single team within a company. Having a bunch of other companies and teams who are already using Opzi may help your sales pitch but is not inherently necessary for your team's Opzi to function. So I'd say the customer acquisition problem is easier than OpenTable's - with the caveat that enterprise sales is never a cakewalk.
