The best startup I was at was one where four engineers who knew each other had dropped out of a big company and started with a consulting project, developing the first version of the product for an early customer (a national lab) using FPGAs. Then they got venture funding to develop an ASIC version, which is when I got hired as employee #12.
The next best one started when a bunch of friends from undergrad - mostly engineers but one with a business degree - convinced a sales person to go in with them on a startup.
In both cases they didn't have to hire a founding engineer - the founding engineer or engineers were part of the original group that got seed funding. Some of the later hires were quite good, and rose to the level of some of the founders or higher, but their success wasn't dependent on the supernatural ability of someone they hadn't yet identified or hired.
To be honest, the whole idea of "I have a great idea, but don't know how to translate it into product, so I'll hire people to do that" seems like a recipe for disaster in so many ways.
