The funnel

Four models.
One funnel.

Every promotion model bills at a different point on the same path. Pick the point that matches how your app makes money — we handle everything to the left of it.

Schematic. Bar heights show the shape of a typical mobile funnel, not measured rates — real drop-off depends on your app, geo and creative.

Our edge

Why advertisers choose Sidereal Tech

We are buyers, not resellers. The same people who plan your campaign are the people watching its source-level numbers every day.

Global inventory, one team

Direct and vetted iOS and Android supply worldwide. Scale a single geo or go WW without briefing a new partner every time.

Performance-only pricing

CPI, CPA, CPL and CPS. You pay for the outcome you name — never for impressions you cannot reconcile.

Operators, not order takers

Every buyer on the team has years of hands-on experience in mobile advertising. Your account is run by people who have scaled apps before.

Solutions snapshot

One team.
Every model that matters.

CPI

User acquisition

Install volume at a fixed cost per install, on iOS and Android, in the geos you name.

CPA

Action campaigns

Pay only on the in-app event that matters: registration, deposit, purchase or subscription.

CPL

Lead generation

Qualified, tracked leads for finance, insurance, education and service applications.

CPS

Revenue share

Commission on confirmed sales — the model that ties our payout directly to your revenue.

Retargeting

Re-engagement

Bring lapsed users back with audience-level retargeting across the same global inventory.

Creative

Creative & optimisation

Localised ad creative, split-tested per geo and per source, refreshed while campaigns run.

See how each model works

Most media buying problems are not media buying problems. They are measurement problems, or creative problems, or a payout that was never going to work in that geo.

We would rather tell you which one it is in week one than quietly spend your budget for a quarter.

How we work

Four steps
from brief
to scale

01

Brief & KPI

You share the app, the target geos, the event you want to pay on and your target CPA or ROI. We come back with a media plan, not a rate card.

02

Supply matching

We map your KPI to the right inventory across our global iOS and Android sources, then set up MMP tracking links and postbacks.

03

Launch & optimise

Campaigns go live with source-level reporting. We cut what does not convert and push what does — every day, not every month.

04

Scale & report

Once the KPI is stable we widen geos and volume, with transparent reporting you can reconcile against your own MMP dashboard.

Traffic quality

Quality is the product.
Volume is the by-product.

Cheap installs that never open the app cost more than expensive ones that do. Every source we run is judged on post-install behaviour, not on the click.

  • Source-level transparency. Sub-publisher reporting so you can see exactly where volume comes from.
  • Fraud screening. Click-spam, install hijacking and emulator patterns are filtered and blacklisted continuously.
  • Retention checks. D1 / D7 and in-app event rates reviewed per source, not just at campaign level.
  • Your numbers are the numbers. We bill on your MMP, so there is nothing to argue about at the end of the month.
