My product is focused around companies that allocate resources and track time. My closest competition is 10K ft, Harvest, and Mavenlink, but mine will do things these others aren't doing and will be catered to creative design / technology firms (10 - 10,000).
The only number I found is Harvest says they have 40K+ customers. But how can I go about assessing the entire customer base? I could look at US Labor and Stats, but I intend to eventually be in 100 countries.
Thanks in advance,
