Unit Economics You Need to Know Before Spending
| Feature | Details |
|---|---|
| Average CAC via paid | Dual-sided: buyer CAC $20–$80; seller/supplier CAC $50–$200 (higher because supply is the scarce side) |
| LTV | CAC target: Take rate economics: if you take 15% on $500 avg transaction, GMV CAC = transaction value × take rate / repeat orders. $500 × 15% × 4 transactions/year = $300 LTV → $60–$100 CAC is viable. |
| Stage to start | Post-launch — need to solve both supply and demand sides simultaneously |
Platform & Format Strategy
| Feature | Details |
|---|---|
| Best platform | Supply side: LinkedIn + Google Search |
| Demand side | Meta + TikTok + Google Shopping (depending on category) |
| Best ad format | For supply: 'Earn with us' format showing income potential (Income Calculator) |
| For demand | Product Showcase or social proof |
| Channel order | Supply first via LinkedIn/Google; then demand via Meta/TikTok once supply liquidity is proven; then cross-side network effects take over |
| Budget at stage | Seed: split budget 60/40 supply/demand (supply is harder to acquire) |
| Growth | shift to 30/70 once supply is healthy. |
The Core Creative Challenge
Marketplace ads need two entirely different creative strategies — supply-side ads are B2B recruitment ('earn $X on our platform'), demand-side ads are B2C commerce ('find X here'). Most startups mistakenly blend them.
What Separates Winners From Wasted Spend
Income specificity on the supply side. 'Earn $1,200/month on weekends' outperforms 'join our platform'. Real provider income data (even from 5 early suppliers) transforms conversion rates.

The Mistake That Burns Budgets
Trying to grow both sides simultaneously with one ad budget — pick the scarce side (usually supply) and over-invest there until you have enough to guarantee buyer value, then shift budget to demand.
