tl;dr -- offer customers something they can't buy at a price their willing to pay. My personal, non-software example was to identify an untapped opportunity in my field, technical recruiting. My clients had 20 to 100 employees, no internal technical recruiter, had already recruited their core team, has run out of organically generated people to interview, and had raised a Series B or later in funding. In 2010, the only options available to them were contingency recruiters, contract recruiters who wanted 6 to 12 month full time contracts, and inexperienced admin staff (aka not experienced technical recruiters). After learning that it super competitive to sell traditional recruiting services to my clients, I decided to develop a workflow that allowed me to offer them part-time hourly recruiting with no long term commitment. Typically this started off as 10 to 30 hours a week with no commitment (aka fire me at any time). This model worked great, and in 2 years I scaled from just me billing 30 hours per week with one client to 15 people (part time & full time) billing several hundred hours per week. Service business are not software businesses, but they do share at least one thing in common; selling a product or service customers need & can't buy in an industry you understand is a heck of a lot easier than trying to make something up from scratch. Good luck! </rant>
