What's inside
Made for founders building two-sided marketplaces
6 prompts + 1 skill- PromptMarketplace Cold Start — Constraining the Market, Seeding Supply and Single-Player Value
Solves the chicken-and-egg problem for a new marketplace — choosing a narrow starting market (one city, category or niche), which side to seed first, concierge and manual matching, tools that give one side value before the other arrives, and milestones for expanding.
- PromptMarketplace Liquidity Metrics and Dashboard
Defines and tracks the metrics that show whether a marketplace is working — search-to-fill or match rate, time to match, buyer and supplier repeat rates, supply utilisation, take rate, cohort retention by side and market-level health — with a weekly review.
- PromptMarketplace Take Rate, Pricing Design and Preventing Disintermediation
Designs how a marketplace makes money — commission, subscription, listing or lead fees, who pays, take rate relative to the value provided, and keeping transactions on the platform through value (payments protection, insurance, tools) rather than only restrictions.
- PromptMarketplace Trust and Safety — Verification, Reviews, Disputes, Prohibited Listings and Fraud
Builds trust and safety for a marketplace — identity and quality verification proportionate to risk, honest review systems that follow fake-review rules, dispute resolution, prohibited listings, payment fraud controls and an escalation process for serious incidents.
- PromptMarketplace Supply Acquisition, Onboarding and Retention
Grows and keeps the supply side — targeting providers who will deliver quality, honest earnings messaging, onboarding that gets them to a first transaction fast, quality tiers, tools that help them succeed, and understanding why good suppliers leave.
- PromptMarketplace Regulation Checklist — Platform Rules, Consumer Protection, Payments and Worker Status, for Counsel
Organises the regulatory questions a marketplace must answer as it grows — platform obligations such as the EU Digital Services Act, platform-to-business transparency, consumer protection, payments licensing, tax reporting for sellers, worker classification and data protection — as a checklist for counsel.
- SkillMarketplace Operator Partner
A standing partner for marketplace founders: cold start, liquidity metrics, take rate and disintermediation, trust and safety, supply growth and regulation — narrow first, liquidity before scale, trust above all.

Marketplaces fail when they launch too broadly with too little liquidity, so you start narrow, seed the harder side by hand and expand only when matches happen reliably. CONTEXT: The marketplace idea: who buys, who sells …
