Enterprise markets are hard to sell into for a small company, although it’s not impossible. Purchasing decisions take a long time, there are a lot of requirements even to be considered, and contracts tend to be custom and require a lot of work. Many enterprise customers won’t buy from small companies out of fear they will vanish within a few years, and that fear is not unfounded. In fact, even for your own bootstrapped business, I would recommend against using services offered by companies smaller than yourself. You will be better off looking for a market that is comprised of small to medium-sized businesses and self-employed freelancers.
