What they are
Fathom
Fathom records, transcribes, and summarizes meetings on Zoom, Google Meet, and Microsoft Teams, then delivers a structured recap with action items within seconds of the call ending. It is used by individual contributors, sales reps, consultants, and customer success teams who want to stay present in conversations rather than writing notes. A bot-free capture mode launched in 2026 for Mac lets participants see no extra attendee in the call. CRM sync to HubSpot and Salesforce is available on paid tiers, and the free plan is genuinely unlimited on recordings and storage.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
