However, what Brunson cleverly conceived with ClickFunnels is to create a SaaS that can integrate with the world's most popular platforms and virtually anyone can quietly launch a funnel in hours as opposed to weeks of hefty coding and programming. As a fervent user of ClickFunnels myself, I can tell you that the system is impressive beyond measure.
Another is a new approach to interaction. Organizations will need to look beyond traditional inpatient and outpatient care when they think about interaction with consumers. They will need to look at all the personal and commercial activities of their consumers, to find ways to become part of those activities, and to ensure that health-related interaction is continuous, not episodic.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer. 
In marketing automation, Ryan Deiss, co-founder of Digital Marketer, often describes the sales funnel as a multi-step, multi-modality process that moves prospective browsers into buyers. It's multi-stepped because lots must occur between the time that a prospect is aware enough to enter your funnel, to the time when they take action and successfully complete a purchase.
