Zelf Homepage social proof with cash offer CTA

This ad for a crypto banking startup hits you with two powerful motivators: “limited time” and “everyone’s already using it.”

Marketing analysis

The sleek dark design screams futuristic finance. But the real win is in trust stacking. You see FDIC insurance, household media logos, and massive user numbers—all before you ever scroll. Then they push you to act now with a $25 sign-up bonus expiring this month. Classic urgency meets authority.

Why it works

• Urgency: “Till the end of this month” drives instant decision.
• Social proof: 1M+ global customers make it feel safe to join.
• Authority signals: TechCrunch, WSJ, Forbes logos = instant credibility.
• Tangible reward: $25 bonus lowers signup resistance.

Examples

• Robinhood used free stock bonuses to onboard millions.
• Coinbase earned 56% more conversions during limited-time referral promos.
• Revolut plastered publication logos early to build trust fast.
