Ok, so I'm confident in declaring your assumption false. This isn't a green-field market where the first credible entrant has a reasonable chance of capturing a large part in one go, it's a mature, slow and conservative market. They are extremely unlikely to read about a new shiny thing on a blog, decide that afternoon to start using it, and in that decision cut out the superior product that launches two months later. Sure, by the time they've decided to use a new thing, they are unlikely to change again soon, and if, at the time some team is evaluating a new system yours isn't on the market, you wont be considered. So take a deep breath, stop sweating "first to market" startup tropes, build a good product and start thinking about how you're going to sell into this market instead that's probably a much bigger challenge than building the product in the first place.
