Runs a weekly MarTech stack review newsletter with 8,400 subscribers. Regularly posts "underrated SaaS tools" threads and explicitly solicits pitches from B2B tool builders. Engagement rate on tool recommendation posts is 3× their average.
Their audience is your exact ICP — B2B founders who evaluate and purchase marketing tools before the mainstream. A single mention in their stack review drives qualified inbound because readers trust their curation. They post about "automation gaps in outbound" every quarter.
Offer a free lifetime account in exchange for an honest review in their next stack thread. Open with a reference to their November post on outbound sequencing gaps — it's specific enough to avoid sounding like a cold template.
