Marketplace Liquidity
A liquid marketplace is one where:
- A buyer who arrives finds something worth buying within 3 minutes of browsing
- A seller who lists an item sells it within 14 days
- Both sides feel the platform is worth returning to
Below the liquidity threshold, both sides churn. Above it, the flywheel self-sustains.
Minimum Viable Liquidity​
For buyers: Need to see at least 50 relevant items in preferred category in under 2 minutes.
- 50 listings in women's tops → ~6 sellers in that category
- Compelling browse across 5 categories → ~30 sellers minimum
- "Wow, there's so much here" feeling → ~100 sellers, ~900 listings
The hard gate: reach a critical mass of listings before spending on paid buyer acquisition, sending paid traffic to thin inventory wastes budget. Close the gap with listing challenges (e.g. "Top 20 sellers this week get featured on @pasarseken.id"). Specific listing/seller thresholds and timelines are tracked internally.
Liquidity Ratios​
| Ratio | Healthy | Minimum viable | Problem |
|---|---|---|---|
| Listings per active buyer | >15 | 8 | <5 |
| Buyers per active seller | >2 | 0.8 | <0.5 |
| Transactions per active seller/month | >1.5 | 0.6 | <0.3 |
| Avg days to first sale | <14 | 21 | >28 |
The Self-Sustaining Flywheel​
The flywheel becomes self-sustaining, organic growth exceeds churn without active intervention, once the seller and buyer bases reach a critical density with healthy retention, referral contribution, and organic reach. The specific thresholds and target timeline are tracked internally.
Before that point, every week requires active intervention, seller outreach, content production, personal onboarding. After that, the platform compounds without the same manual effort.
The Supply-First Rule​
"Every failed marketplace in history failed because they scaled demand before supply was ready. The buyer arrives, finds empty shelves, leaves, and never comes back."
Hard gate (non-negotiable): No paid buyer acquisition, no buyer-focused content campaigns, no public launch announcement until:
- 150 sellers active with 10+ listings each (1,500 listings)
- 10 completed soft-launch transactions
- Dispute policy live and tested
- Biteship integration confirmed
The SEKEN Flywheel​
Sellers list → Content about real items →
Buyers discover → Buyers buy → Sellers get paid →
Sellers tell other sellers → More sellers join →
Content gets richer → More buyers discover
The content layer is what differentiates SEKEN from Carousell. Every listing is a story. Every story is acquisition content for both sides.
Category Concentration Strategy​
Liquidity is not about total inventory, it is about density in the categories where buyers are actually looking. 1,000 listings across 50 categories = 20 per category = frustrating. 1,000 listings across 4 categories = 250 per category = compelling browse.
Priority categories for months 1-3:
- Women's casual tops and blouses
- Denim (jeans, jackets, shorts)
- Dresses and skirts
- Bags and accessories
These cover 70%+ of Indonesian fashion seken search behaviour.
Hard gate: Do not actively recruit sellers in new categories (menswear, children's, shoes, sportswear) until each of the 4 priority categories has 200+ listings.
Month 4+ expansion: Review actual buyer search data in Supabase monthly. Open the two most-searched zero-result categories. Never open more than two at a time.
Geographic Liquidity, Bali-First Rule​
Do not market nationally before Bali liquidity is established.
A Jakarta buyer purchasing from a Bali seller pays IDR 30-45K shipping on a IDR 120K item, a 25-37% surcharge that kills the value proposition. Same-city Bali transactions have lower shipping cost, higher buyer trust, higher repeat purchase rate, and lower dispute risk.
National shipping becomes compelling once average order value rises past a threshold (tracked internally). Before that, concentrate buyer acquisition on Bali.
Buyer:Seller Ratio​
A healthy buyer:seller ratio (roughly 1.3 buyers per active seller) means every seller has multiple potential buyers, and is the point where Boost ROI starts to make sense for sellers. Month-by-month target counts are tracked internally.
