It's all about growth. I don't think a potential suitor would be put off by your choice of technology, but if your choice of technology slows your growth, then that will definitely put off a potential acquirer. You don't want to put yourself in a position where you have to buy another SQL Server license instead of hiring a developer, or use the developers you have to invent contrived architectures in order to reduce licensing costs. If there is any chance you might run into that kind of problem before getting acquired, I would rather bite the bullet now and get started on a platform that doesn't artificially limit my architectural choices.
