Cometly: AI ad attribution for B2B SaaS makes $197k a month, verified
Cometly sells ad attribution to B2B SaaS companies with an AI chat layer for questioning ads data, at $197,000 verified monthly recurring revenue (TrustMRR, checked November 2). The founder-reported 90% margin is unverified, but the model itself is the lesson: one narrow B2B niche with buyers already paying, plus one clear AI feature.
