Its purpose is to cover the crowdsourcing marketplace for testing, which we will refer to as crowdtesting. There are two main categories of crowdtesting services; vetted communities and unvetted communities. Vetted implies that the individuals have been vetted and verified by the crowdsourcing firm before connecting them with a client. There are also full service providers offering crowdtesting. This market concentrates on the pure-play vetted and unvetted providers.
