Platform marketplace extension play
Build a simple add-on or extension for an established platform's marketplace (Notion, Figma, Shopify) to tap into its existing warm audience searching for solutions.
Why this can grow a startup
The platform already has millions of users actively searching for solutions. Trust is inherited from the platform itself, dramatically lowering the acquisition barrier. Users discover your tool while already in a buying or problem-solving mindset, leading to higher conversion rates. The marketplace provides free SEO and discoverability that would cost thousands in ads to replicate.
Company example

When to use it
Use this when Communities, Partnerships, SEO is relevant to 10K+ and you can run a bounded test with a free budget.
