referral programs

Chris Best of Substack and Jonathan Gill of Backtracks discuss how podcasts and newsletters can earn revenue through advertising, subscriptions, or a mix of both. They argue that creators need reliable measurement to understand audience engagement and advertising value, while direct payments can support niche work that advertisers might overlook. Best describes Substack’s approach to growing newsletters through free, shareable posts, referrals, and paid subscriptions. The speakers also recommend starting with a clear purpose, publishing consistently, and learning from early audience feedback.

Drew Houston describes how personal frustration with file access led him to build Dropbox, recruit co-founder Arash, and validate the idea with a demo video and early user feedback. He explains how a startup’s needs expand quickly, why a founder’s job changes as the company grows, and how reading, mentorship, and studying businesses outside technology can help build management judgment. Dropbox explored adjacent products before deciding to refocus on collaboration, illustrating how focus can require closing products the team cares about. Houston also discusses Dropbox’s growth through activation improvements and viral referrals, and frames going public mainly as a financing and liquidity decision with operational costs.
