I've built 2 B2b products now, and I can say that it depends entirely on what type of business is your target market. Case in point: -RateMyStudentRental sells to colleges and universities. Schools are essentially large corporations, and the sales cycle is excruciatingly long (a year or more). To top it off, my absolute maximum market in the US is around 5500 possible clients if I garnered 100% of the market (probably actually less because some schools are commuter campuses which puts them outside my market). I've been doing it since 2007, and I'd tell you that you may get 3 customers in 3 years if you're incredibly lucky. -LeadNuke on the other hand is a B2B product that can be useful to almost any type of company, startups to multi-national corporations, franchises, and freelancers. I haven't even really told anyone about it yet (except the occasional HN post), and it already has around 30 companies signed up and using it. In this case, I'd tell you, pshh that's easy. My point: it depends. The only way to know is to try it. Any speculation before trying it is just that.
