Fibbler is a LinkedIn ads attribution tool built by Adam Holmgren that went from side project to $700K ARR in under a year. Their playbook is the challenger brand GTM archetype: build an audience first, launch into trust, amplify with paid, and let the product sell itself.

Before writing a single line of product code, Holmgren spent three years posting tactical demand generation content on LinkedIn — building credibility with 25,000 B2B marketers who would later become his first customers.
