Podcast interview (recorded Sept 6, 2016) where host Brad Costanzo talks with growth hacker Justin Mares about rapid e-commerce growth tactics. Justin describes founding Kettle and Fire (a shelf-stable bone broth brand launched ~10 months before the interview and scaled to “multiple seven figures”), content and influencer strategies (long-form posts ~2,000 words published ~1–2x/week, organic distribution via email, Reddit, Facebook groups, influencer outreach on Instagram), and a software product FOMO (formerly Notify) that shows social proof notifications — Justin reports installing it increased conversion rate ~30% on his store. They also discuss influencer payment tactics (micro-influencers paid ~$20–$30 via PayPal for a post), acquisition structure for buying the app (partial seller note/earnout), and broader marketing trends (avoiding intrusive pop-ups, favoring user-friendly engagement).
