Solve The Cold-Start Problem On Both Sides Of Your Marketplace
Marketplaces need buyers to trust sellers they've never heard of, and sellers to trust that buyers will actually show up. Show live transaction activity and review proof that builds confidence on both sides at once.

The Challenge & The Solution
Without NotiProof
- Two-sided trust problem: Buyers won't transact without seller credibility, and sellers won't list or engage without proof that buyers actually convert.
- Cold-start liquidity gap: New or niche marketplaces look empty at launch, making both sides hesitant to be the 'first' to commit.
- Unfamiliar seller anxiety: Unlike single-brand e-commerce, buyers are trusting individual third-party sellers they've never interacted with before.
