A note on honesty

Cognism is excellent for European prospecting with industry-leading phone-verified mobile numbers. If your primary market is EMEA and you need a built-in dialer, Cognism is hard to beat. SIE Data is a different tool — built for US regulated industries with government-verified data and built-in intent signals.

Companies that need US compliance (FCRA, CCPA, DROP) rather than GDPR-only

Teams that want built-in intent signals instead of paying extra for Bombora

Organizations that need data provenance for audit and compliance reviews

Companies that need automated daily lead delivery, not manual searching
