I don't claim to know that much about it, but nothing I've heard suggests that there's that much room for automation in the industry. Every wedding is a one-off with at least some custom requirements, and none are ever repeated. Where does an app or website come in? The experienced people in the industry know who to trust to get it right, who can do what, and roughly what it costs. They have the human ability to take care of the small problems without bothering the family, and know what issues to escalate to them. Maybe the planners would like and be willing to pay for some tool that helped them organize things, but there's probably too much individual customization needed to make any such solution practical to build cheaper and better than Excel or something.
