Aligned incentives
We are paid on the same event you are optimising for. If the KPI is not hit, that is our problem before it is yours.

A media buying team
built for mobile.
Sidereal Tech Limited buys mobile app media, worldwide. No reselling, no black boxes — just experienced buyers, global iOS and Android inventory, and payouts tied to the outcomes you actually care about.
Who we are
Years in the industry,
Years in the industry,
on your side of the table.
Mobile advertising moves fast. Attribution windows change, privacy frameworks change, and the sources that worked last quarter go quiet this one. Our team has spent years inside that industry — buying, testing, cutting and scaling — which is why we plan around what will still work next month, not just what is cheap today.
We work with app advertisers and agencies who want a single accountable partner for global user acquisition, rather than a dozen networks to reconcile.
How we operate
Four principles we do not trade away
Radical transparency
Sub-publisher IDs, geo splits and daily numbers. Nothing is hidden behind a single aggregated line item.
Quality before volume
We would rather deliver less traffic that retains than more traffic that churns and burns your payout.
Speed of response
Campaign questions answered in hours, not days. Budgets and caps adjusted while the traffic is still worth adjusting.
The name
Sidereal: measured
Sidereal: measured
against the stars.
A sidereal day is measured against a fixed point in the sky rather than the sun — the more precise of the two. We picked the name because that is how performance media should work: measured against a fixed, agreed reference point, every single day.
In practice that reference point is your MMP. It is what we optimise to, what we report on, and what we invoice against.
Who we work with
Built for two kinds of buyer
You own the app
You have a product, a target CPA and a growth number to hit. We become the media buying arm that gets you there without adding headcount.
- Global UA on a single set of terms
- Payout tied to installs, actions, leads or sales
- Creative testing handled on our side
- One invoice, one point of contact
You own the client
You need reliable, screened volume for a client campaign — delivered on your terms, with reporting you can pass straight through.
- White-label friendly delivery
- Clean sub-publisher reporting
- Geo and volume caps respected
- Fast ramp-up and fast pause
