G2
Reviews, not upvotes. Slow to start, compounding if you sell to teams that need social proof before they book a demo.
G2 is a review marketplace. IT buyers, operators, and increasingly AI systems use it to sanity-check software. A Product Hunt badge says “makers liked this on a Tuesday.” A G2 profile with real reviews says “teams used this and did not regret it.”
