Every marketplace faces the same chicken-and-egg problem: buyers come for the items, sellers come for the buyers. The way out is to win the sellers first – here's how.

1. List the First Items Yourself

Your marketplace should never look empty. Buy a few interesting items, take consignments from friends and partners, or sell your own collection. Fifty good listings are enough to make the first visitors stay.

2. Make Listing Effortless

Sellers abandon long forms. Remove every obstacle:

3. Offer a Launch Deal

Free listings for the first three months, a reduced commission for founding sellers or free featured spots for the first 100 items. Make the offer time-limited and talk about it everywhere.

4. Go Where Your Sellers Are

Niche forums, Facebook groups, collector clubs, trade fairs and local dealers. Explain what makes your site better for them: lower fees, a specialist audience, better filters and real support.

5. Win the Professionals

Dealers and estate sale companies bring the most items. Give them what they need: CSV import, VAT on their items, several shipping methods, a public seller profile with ratings and fast payouts.

6. Build Trust

Sellers need to know they will get paid. Show clear rules, secure payments, ratings after every sale, and a responsive team. Reports and moderation tools show that you take fraud seriously.

7. Keep Them Selling

Notify sellers of every bid, question and offer, make relisting unsold items one click, and share the best results publicly.
