OK, I think the number one thing to ensure about this business, if you want to revolutionize hiring, is to show that it works. If I can apply this idea to my potential hires, I'm going to give you all the dollars because the alternative is spending my team's precious cycles on interviewing.

I think there are a lot of paths that lead to your business making money but ultimately going down a path towards "yet another technical certification" - technical certifications are a negative hiring signal for a good reason. Avoiding this pitfall, I think, is the hardest part but perhaps the key to success.
