Marketing for Startups with Fexingo · 2026-07-14 · 11 min
In this episode of Marketing for Startups with Fexingo, Lucas and Luna break down how one B2B SaaS startup grew from zero to 10,000 signups by building a single Slack community - no paid ads, no PR, no growth hacks. They walk through the playbook step by step: how the founder seeded the community with 50 manual invites, how she structured channels to maximize value and minimize noise, and the exact weekly content cadence that turned lurkers into evangelists. They also discuss why community-led growth works especially well for early-stage startups with no marketing budget, the dark pattern of overly moderated communities that kill organic word-of-mouth, and the one metric that matters more than member count: active participation rate. If you are a founder or early marketer wondering whether to invest in a community, this episode gives you a concrete framework and a real-world example to benchmark against.
