Frequently asked questions

How to solve the chicken-and-egg problem?
Proven strategies: (1) 'unique side first' (aggressively recruit sellers or buyers before the other), (2) hyper-localize at launch (1 city, 1 category to reach liquidity), (3) pre-launch supply (sign 50-200 sellers before launch), (4) integrate a captive supplier (managed stock to fill supply gaps).
What take-rate to set?
Typical take-rate by segment: C2C 5-12 % (Vinted, eBay Pro), B2C niche 8-20 % (Etsy, Vestiaire Collective), B2B 3-12 % (Manomano, Alibaba), services 15-30 % (Malt, Upwork). Take-rate must cover the acquisition cost of 1 buyer AND 1 seller (4-15 % of transactions).
Which indicators to track in a marketplace?
GMV (Gross Merchandise Value), effective take-rate, liquidity (% of listings sold within X days), active buyers/sellers, buyer/seller ratio (target 5-20:1), repeat rate (% of buyers who re-order within 90 days), CAC per side, unit economics (net margin per transaction).
How to finance the launch in Lille?
Bootstrapping is hard due to high initial capital intensity. Typical mix: seed VC 1-3M €, angels 200-800K, public innovation aid (100-500K grant, 200K-1M loan), accelerators. Starting with a regional MVP limits needs.
