What you can build
A platform where one side lists (sellers, freelancers, service providers) and another side discovers and transacts (buyers, clients).
Why this matters now
Marketplaces are the highest-leverage business model that exists. The only reason most people don't build one is the perceived technical lift — which AI has erased.
How to build it
- 1
Pick a sharp niche
Marketplaces win by going narrow. 'Vetted Webflow designers for SaaS' beats 'designers.'
- 2
Define the two roles
What does the seller upload? What does the buyer search? What is the transaction?
- 3
Build it in Lovable
Two auth roles, a listing schema, search, and Stripe Connect for payouts.
- 4
Seed the supply side first
Manually onboard the first 20 listings. Then turn on demand.
