# Platform Ecosystem Canvas

Design and analyze platform businesses by mapping the core interaction and the ecosystem that enables it.

## Steps

1. Define the **Core Interaction** -- what is the single most important exchange on the platform?
2. Identify **Participants** -- who are the producers and consumers? Are there multiple sides?
3. Define the **Value Unit** -- what is created and exchanged (listing, post, video, data)?
4. Design **Filters** -- how does the platform curate and match supply to demand (search, algorithm, curation)?
5. Map **governance rules** -- what rules keep quality high and prevent abuse?
6. Identify the **chicken-and-egg** problem and the strategy to solve it

## Output Format

- **Core Interaction:** [Producer] creates [Value Unit] for [Consumer]
- **Producers:** [Who and what they contribute]
- **Consumers:** [Who and what they seek]
- **Value Unit:** [What is exchanged]
- **Filters:** [Matching/curation mechanism]
- **Governance:** [Quality and trust rules]
- **Cold start strategy:** [How to solve chicken-and-egg]
