How we work

What happens after you write to us

Brief

App, store links, geos, KPI and budget. If you have an MMP, tell us which one.

Plan and forecast

Sources, formats, split by geo, expected volumes and CPI/CPA. You approve before anything is spent.

Test launch

Small budget across several sources. Manual quality check on each one before it scales.

Scale

Budget moves to sources that hit the KPI. Weekly report, daily optimization, same-day answers.

Inventory and quality

Connect to your audience and premium inventory

Scale that does not depend on one source, and traffic we would put our own budget on.

  • Direct relationships with publishers
  • Multiple SSPs for additional reach
  • Simple integration through your MMP or S2S
  • Manual pre-launch checks and built-in traffic tools during flight
  • Source-level reporting you can reconcile with your own data

Questions advertisers ask

Before you write to us

What is the minimum budget?

There is no fixed minimum. A test usually needs enough budget to get statistically meaningful results in your geos, and we tell you that number in the plan. If your budget does not fit a meaningful test, we say so.

How do you charge?

Depends on the model: CPI, CPA, CPM or a management fee on top of media. We agree the model in the plan, and the reporting matches the model.

Which MMPs and tracking do you support?

Any MMP that supports postbacks (AppsFlyer, Adjust, Branch, Singular, Kochava and similar), plus S2S tracking for web and VAST for CTV.

How do you protect against fraud and low-quality traffic?

Every source is checked manually before it gets budget. During the campaign we use traffic-checking tools and your MMP fraud reports, and cut sources that do not hold up. You see source-level data, so nothing is hidden behind an average.
