About 1% Founder (100 Mastery)

Members get practical frameworks, AI-powered thinking tools, case studies of real founders and weekly insights.[1] The material includes frameworks from Alex Hormozi, among them 100M Offers.[1]

O'Brien runs a YouTube channel under the 1% Founder name, focused on helping founders make the right next move, and offers a 4-Min Founder Scan.[2] The 1% Founder website, with the tagline "The decision behind the decision", promotes the 30-Minute Founder Breakthrough, a free live session with Jerry that starts from the founder's current problems.[3] The site says a limited number of sessions are offered each week and that the call carries no pitch.[3]
