01 — Capabilities

Three disciplines. One growth engine.

Media buying, monetization and creative are usually split across three teams. We run them as one loop, so what we learn from revenue feeds directly back into acquisition.

/ 01

User acquisition

Paid media built around unit economics, not vanity installs. We structure channel mixes by payback window, then scale only what holds its margin.

  • Full-funnel buying
  • Geo & audience tests
  • Budget pacing
/ 02

Monetization

Waterfall and bidding strategy tuned against retention. We find the ad load and format mix that lifts ARPDAU without giving back D7 or D30.

  • Mediation setup
  • Floor optimization
  • Format testing
/ 03

Creative & signal

A weekly creative pipeline and clean measurement layer. Concepts are tested in batches; winners are briefed forward before fatigue sets in.

  • Concept sprints
  • Incrementality tests
  • MMP & BI hygiene
02 — Operating model

How an engagement runs.

No black boxes. A four-stage cycle with a shared dashboard, a weekly decision log, and clear owners on both sides.

01

Diagnose

We audit historical spend, MMP events, creative library and monetization setup to find where value leaks.

Audit & baseline
02

Model

Payback targets, channel roles and test roadmap are agreed up front — one plan, one source of truth.

Forecast & targets
03

Launch

Campaigns go live in structured test cells. Budget is staged so learning happens before scaling.

Test & read
04

Compound

Winners graduate to always-on programs, and the next test cycle starts from a stronger baseline.

03 — Channels

Wherever your users already are.

We stay platform-agnostic. The mix is chosen per product, per market, and revisited as signal quality and costs move.

We buy on the platforms that can prove incrementality, and we keep a small experimental budget for the ones that might. Every channel has a defined role: discovery, conversion, or re-engagement.

Managed with server-side postbacks, cost aggregation and a single daily reporting layer — so channel comparisons are apples to apples.

04 — Why Stimulatx

Small team. Senior hands.

We keep the account team deliberately flat. The people who plan your media are the people who optimize it at 2 a.m. during a launch window.

Stimulatx Technology Limited is a Hong Kong–based performance marketing company. We work with a limited number of partners so that each account gets real attention.
