In This Case Study
Legacy screening designed for banks could not match marketplace velocity
Tools designed for financial institutions processing thousands of transactions could not absorb marketplaces onboarding tens of thousands of merchants. Entity resolution degraded in precisely the jurisdictions where marketplace expansion was fastest.
API-driven screening at the point of merchant onboarding
Sayari was integrated into merchant onboarding, creating an automated screening layer that verifies merchant identity, resolves corporate ownership, and checks sanctions status against 10.6B+ source records.
Onboarding decisions resolve programmatically — at marketplace velocity
Onboarding that previously required manual research now runs automatically. The compliance team operates with confidence that every merchant on the platform has been verified against authoritative data.
The challenge
The global e-commerce marketplace model has created a new category of compliance obligation. Platforms that host hundreds of thousands of third-party merchants carry KYB, sanctions, and anti-money laundering responsibilities for every seller on their marketplace. Regulatory expectations have shifted from caveat emptor to platform accountability: if a sanctioned entity operates a storefront on your marketplace, you are responsible.
One of the world’s largest e-commerce platforms faced a screening challenge unique to its scale. With a merchant population well in excess of 100,000 active sellers across dozens of countries, the platform needed entity verification and sanctions screening that could operate at marketplace speed — resolving merchant identity in seconds rather than days, and covering jurisdictions where many merchants had never been verified against authoritative data.
- Platform accountability: a sanctioned entity on the marketplace is the platform’s liability
- Tools designed for banks could not absorb marketplace onboarding velocity
- Entity resolution degraded in precisely the jurisdictions where the marketplace was growing fastest
- Onboarding delays + transaction holds + regulatory exposure with each unverified merchant
The solution
The platform integrated a primary-source corporate data platform into its merchant onboarding workflow, creating an automated screening layer that verifies merchant identity, resolves corporate ownership, and checks sanctions status against 10.6B+ source records at the point of onboarding. The API-driven architecture matched the platform’s technical requirements: high throughput, low latency, and programmatic integration with existing systems.
- Primary-source corporate data layer feeds the company’s proprietary risk scoring
- 500M+ companies in 250+ jurisdictions — entity identity, ownership, relationships
- Graph architecture surfaces non-obvious shared ownership, SOE, and MCF connections
The results
Building for the Future
The marketplace now operates with a screening capability that scales with its growth. Every new merchant, in every new market, is verified against the same depth of corporate intelligence. The compliance team has moved from reactive, sample-based screening to comprehensive, continuous verification — transforming marketplace compliance from a bottleneck into a competitive advantage.
