As far as MU, he claims, "I brought the ‘MU Certification’ badge front and center because I’ve been told that potential health incentives factor heavily in a practice’s or hospital’s decision to adopt a new platform."
So it sounds like it's relevant to actual customers.
The person making the purchasing decision will almost certainly know about this. A provider must meet certain "meaningful use" criteria to be eligible for tax credits, and so this designation indicates that DrChrono meets some of these requirements.
I think it's fair to say that most organizations currently looking to buy an EHR are doing so because they want to take advantage of these tax incentives.
Caveat: You can throw out any data points if those providers are part of a larger healthcare network that makes all the decisions for them about what software to buy. For example, if the doctor is part of Blah Blah Medical Group and they're (probably begrudgingly) forced to use something like Relay Health, then they've essentially offloaded that decision to an administrator somewhere.
