Gavin Hammar

Founder Gavin Hammar shares guidance for builders drawing on his experience bootstrapping and exiting Sendible (acquired in 2021) and now leading Swarm and StoryPrompt. It’s for founders, creators, brands, and experts building SaaS, subscriptions, memberships, or paid communities—especially video-first communities. Offerings include a free 30-minute 1:1 chat, a 6-week founder growth challenge, and help starting a paid community with Swarm.

The one-liner

Bootstrapped founder clubhouse behind Swarm and Sendible exit stories.

What they actually sell

Gavin Hammar’s Swarm storefront is a founder-facing presence: free Build a Membership access, a thirty-minute chat offer, and a paid six-week Founder Growth Challenge. Bio proof includes building Sendible without outside funding, a 2021 exit, plus founding Swarm (video-first communities) and StoryPrompt. Help topics emphasise bootstrapping, community-led growth and customer-first building. This is less a topic community than a personal founder hub with selective offers.

Who pays and why

Creators and operators who want membership and SaaS-adjacent growth advice from someone who exited. Free joiners come for proximity; challenge buyers want a time-boxed push. The emotional reason is credible pay-it-forward mentorship without enterprise theatre.

Where the members come from

LinkedIn and X audiences built around the founder brands; Swarm is the clubhouse behind that social presence. Exact follower counts are not listed on the Swarm page. Product users of Swarm and StoryPrompt are an adjacent path — not quantified publicly here.

What's holding it back

Offer mix is personal and light on a single flagship membership narrative. Without one clear recurring product on the page, visitors may not know what joining means week to week.

Steal this

Use a free founder community as the back end of social proof, then sell a short, priced growth challenge to the warm ones.

Would this work in another niche?

Yes for operators with a real exit or acquisition story in fintech, agencies or creator tools.
