“(hero attempts to serve multiple audiences — open-source, indie hackers, SaaS — without naming any)”
The hero must answer "who is this for?" before "what does it do?" Polar serves at least 3 distinct personas (OSS maintainer monetizing their project, indie hacker selling digital products, SaaS founder needing billing). Addressing all three equally means none feel the page was written for them. Each persona has different pains, different alternatives, and different buying triggers.
“Pick one wedge audience for the hero: "Monetize your open-source project without leaving GitHub. Subscriptions, sponsorships, and paid features — in one dashboard."”
Leading with the OSS audience (Polar's origin story and strongest differentiator) gives the hero a clear identity. Other personas discover their use case below the fold. Trying to be everything above the fold means being nothing.
