G2 Crowd is the leading provider of B2B software reviews online. That may not sound like a big niche, but it’s worth billions. Slack, Moz, HubSpot – they’re all leading software-as-a-service providers, and they’re barely the tip of the iceberg. That gives G2 Crowd a lot of clout with business owners, especially for startups. If you’re a software provider, it’s critical that you look yourself up on G2 Crowd. They’ve collected more than 96,000 reviews for different products, so there’s a decent chance someone’s talked about yours at least once.
