Marketplace business

Edit

A platform that connects two or more groups of users and takes a cut of each transaction.

Marketplace business

Marketplaces look like software businesses but behave like operations businesses for the first eighteen months. The product is liquidity — the ability to walk in, find what you want, and complete a transaction. Until liquidity exists in at least one narrow corner, no amount of features helps.

Ideal for

  • Operators who can patiently solve cold-start (chicken-and-egg) problems
  • Niches where supply is fragmented and discovery is painful
  • Founders comfortable doing things that do not scale during liquidity bootstrap

Not ideal for

  • ×Solo builders without runway for a long ramp
  • ×Markets with one or two dominant gatekeepers
  • ×Categories where buyers and sellers already transact on social/SEO without friction

Metrics that actually matter

Watch these instead of vanity numbers.

GMV (gross merchandise volume)
Take rate (% commission per transaction)
Liquidity (% of listings that transact within X days)
Repeat-buy rate
Supply concentration (top 1% sellers as a share of GMV)

How to start

A realistic sequence — not a checklist that hides the hard parts.

  1. 1

    Pick the harder side first

    Almost always supply. Recruit sellers manually, hand-curate the first 50 listings, and treat each like a customer.

  2. 2

    Constrain the wedge

    One city, one category, one buyer profile. A cluttered marketplace looks empty; a narrow one looks busy.

  3. 3

    Make the first transaction friction-free

    Search, messaging, payment, and post-sale support need to feel professional even when traffic is tiny.

  4. 4

    Choose your take rate carefully

    5% feels invisible, 15% leaks sellers to direct channels, 30% only works with deep network effects (Airbnb, App Store).

  5. 5

    Track liquidity, not vanity GMV

    A marketplace where 80% of listings never transact is broken — even if topline grows.

Common pitfalls

The mistakes that quietly kill otherwise sensible launches.

  • ! Building software before validating supply
  • ! Chasing buyers before there is anything to buy
  • ! Letting power-sellers route around the platform once trust is established
  • ! Underestimating trust & safety costs (fraud, disputes, content moderation)
