Ship a Free Companion Tool as Engineering-as-Marketing

Ship a Free Companion Tool as Engineering-as-Marketing is a product-led growth tactic for getting your first users: Instead of buying ads, the founder built a separate free tool (Potion Widgets) that's genuinely useful to the same audience as his paid product (Notion users), designed so people who find the free tool discover the paid one.

It's a strong fit for B2B SaaS and Dev tools / technical teams, and works especially well for Developer tools and SaaS with a clear adjacent free use case. As a product-led growth play, plan for medium effort and expect results to build gradually over time, all grounded in 1 linked primary source.
