SaaStr Publishes Full-Funnel Numbers on Its Own Ad Product: 5.4M Impressions Driving 11,749 Signups

Jason Lemkin published verified performance for an advertiser on SaaStr.AI Media — 5.4 million impressions producing 11,749 clicks to the signup form — framed explicitly against the B2B media norm of wiring money and receiving an unauditable impressions PDF 60 days later. That's a ~0.22% impression-to-signup rate disclosed publicly by the seller, which is unusual enough to be the story. The broader signal for builders: as attribution gets cheap to instrument, the media-buy black box becomes a competitive liability, and publishers who can prove downstream conversion will price differently from those selling impressions.
