Experience and responsibilities

Since 2018 at Mars Media Group, I manage high-volume accounts across multiple verticals, from finance & betting to travel and casual games. I know that across all of them, every decision has real impact and every signal tells a story. The work is fast and dynamic and demands attention to both micro signals and the bigger picture. Our priority is simple: protect client goals, scale only what proves out, and keep teams aligned through our proprietary system. We move quickly because decisions are grounded in live data, clear goals, rapid feedback loops with shared accountability.

What matters most to high-volume clients

Consistency at scale comes from three habits, enabled by Mars Media Group’s proprietary system:
Speed: quick replies with a next step and a time to recheck.
Structured workflow: we track every change in our system and have structured procedures for campaigns, from testing to scale mode.
Judgment: we work closely with data, focusing on the insights and changes that affect ROI and primary KPIs, not background noise.

We take a measured approach. Constantly testing new sources through small, controlled pilots to evaluate quality and down-funnel performance. Once a source demonstrates strong signals, we scale it strategically, while our media buying team identifies and expands to similar high-performing sources across platforms to grow reach.

Wider reach, with high quality

For us, mobile in-app is usually the core. Premium web extends qualified reach and supports remarketing loops. CTV to mobile nudges the right households on the big screen and completes the action on the phone. Apple Search Ads, where relevant, captures incremental intent. Audio adds useful frequency without visual fatigue. The order is deliberate and managed inside our in-house platform so every change is tracked and explainable. Growth comes from a steady test-and-learn loop in our system: source discovery, small controlled tests, promote winners, retire the rest.

Operate at two altitudes

We manage performance on two distinct altitudes: the short-term operational view and the long-term strategic view.

Daily and weekly micro: yesterday by market and source, sometimes by hour. If something threatens agreed goals or ROI, we act the same day. That might mean tightening source-level limits (daily volume, budget and pacing, frequency, or geo/device restrictions), adjusting geo mix, or pausing a source, with a short note on why. New sources enter as small tests with clear limits; only proven sources move to scale. A weekly touchpoint reviews trendlines, seasonality and context like retail peaks or the sports calendar.

Monthly, quarterly and half-year view: we step back to compare longer windows because late installs and late down-funnel actions continue to arrive. This view shows whether changes are compounding, which sources merit more budget, and which should be retired. Keeping the micro views separate from the longer window makes decisions calmer and faster. We do not jump on every trend; we test only when it can drive a clear ROI decision, read both short-term and longer windows, and scale only what proves out.

The toolbox that keeps things stable

Mars Media Group’s proprietary system is the operational backbone. It connects billing, CRM, optimization, reporting and traffic delivery in one place, AI-based optimization modules, acting as a focal point between supply and demand. On top of that:

Measurement: mobile measurement partners plus our BI for cohort analysis and pacing.

Quality: integrated fraud-protection tools and our checks, with thresholds agreed per account and clear escalation rules if a source drifts.

Reporting inside the system: structured change logs and standardized views so any stakeholder can read what changed, why and what happens next.

The result is a complex operation that stays readable as more people join the thread. This discipline is shared across our Performance Division: customer success, BI and analysis, R&D with AI-driven optimization rules, and dedicated media buying teams for mobile and for web.

Reporting clients can use

Busy teams need clarity. We pair a concise narrative with clean tables, and add visuals only when they clarify context. The goal is a decision, not a data dump. Many partners reuse our summaries directly in internal decks, which tells us the format works. Each report ends with a promote-or-pause call for every test so volume grows for the right reasons.

Small practices that make a big difference

Relationships matter. We keep regular check-ins even when results are steady and ask for mutual feedback, so both sides see the same picture. Our team is experienced across many verticals and sized to respond quickly, which helps the account move in step with the partner’s goals. Our media buying team constantly sources new direct supply, tests fresh sources and scales only what proves out in live data.

  • Document why a change was made and when to review it, inside the system.
  • When a request could put goals at risk, explain the trade-off and propose a safer path.
  • Tie new channels to a time-box and an exit plan.
  • Technology assist: we are using AI-driven rules and alerts in our platform to suggest optimizations and monitor thresholds for both buyer and supply workflows.
  • Not every account starts large; our experienced team combined with top-notch technology knows how to prove value and grow together.

Closing note

Large-scale growth isn’t luck. It's craftsmanship. Our team masters the balance between precision and consistency, holding altitude while minding every detail. With disciplined systems, accurate data, and fluent feedback loops, we turn trust into budgets and performance into scale. Stability comes first, growth follows, and that’s how we’ve built some of the strongest mobile user acquisition operations in the world.
