The audience

The hardest-to-reach audience in tech, captured mid-build.

1

Create your campaign

Add your brand, headline, icon, and destination. Top up your wallet, no card needed to start.

2

Set your bid & targeting

Bid by CPM and target by country, region, city, or OS — finer geo costs a little more. The highest bid serves first, so you’re always in control of spend.

3

Go live & measure

Your ad enters the spinner instantly. Watch verified impressions, clicks, and cost-per-result update in real time.

Measurement

Pay for attention you can prove.

You’re billed only for impressions that pass server-side verification and fraud screening, never for bots or unrendered ads. Every metric is on your dashboard, live.

CTR

Clicks ÷ verified impressions, engagement at a glance.

CPC

What each click actually costs you, in real time.

CPI

Cost per verified impression, your true reach price.
