Alternatives to G2 Crowd include Engagio, Terminus, Demandbase, SimilarWeb, DiscoverOrg, Azalead etc. After spending years in the enterprise software industry, we saw glaring problems in how business technology was bought and sold. There was nowhere to turn for real, unbiased feedback or for advice from people who had actually implemented and used the software and related services. So we started G2 Crowd to be a trusted source of enterprise software reviews from real users. We launched our beta in February 2013 and have collected more than 10,000 reviews of products across more than 200 categories.
