Robinson referenced Sixth Sense as the company that sent Retention.com a cease-and-desist letter shortly after RB2B launched, describing the episode as a PR opportunity that made every Sixth Sense customer aware of RB2B. He did not provide revenue or customer figures for Sixth Sense, and no figures about Sixth Sense should be taken as company-confirmed.
Robinson also cited Leadpages as a cautionary benchmark, noting that it stalled at $17 million in ARR due to churn despite being a business with similarities to RB2B's content-and-community model. He mentioned Clearbit Reveal, saying the Clearbit team told him churn was a disaster for that product and that the only fix was getting other departments using other products. These figures and characterizations are Robinson's descriptions of competitors, not figures confirmed by those companies.
Jasper AI was discussed as a shared-office peer rather than a direct competitor. Robinson said the Jasper team went from zero to $50 million in ARR with six people in twelve months before raising capital. This is Robinson's recollection, not a Jasper-confirmed figure.
