Multi-million-$ ad budgets across Meta, Google & TikTok

Clean data
Compounding spend

The budget keeps growing. The clarity doesn't.

Usually the fix isn't spending more — it's trusting your numbers first. That's the whole job, in three steps.

Step 01

Diagnose the measurement

Before a rupee of budget moves, I make every number in your stack agree with every other number.

What happens A 1–2 week audit of every place a number is born or moved — the SDK, the MMP, each ad platform, the warehouse, the dashboards.
Method Event-by-event parity checks · MMP-to-channel reconciliation · purchase de-duplication · rebuilding metric definitions that don't hold up.
You end up with A short written diagnosis: what's broken, what it's costing you, and the fixes ranked by impact — plus the fixes themselves.
See a real example
On one subscription account, the MMP and the ad platform disagreed on spend by 6×. I traced it to a reporting bug, a value vs value_2 mismatch in the SDK, and purchase events firing twice — all fixed inside a day, before more budget was misallocated.

Step 02

Reallocate the spend

With numbers you can trust, budget moves off what's quietly losing money and onto what's proven to convert.

What happens I read cohort, geo and placement performance, then restructure the account so spend follows real returns — not last-click flattery.
Method Cohort & geo analysis · Test / Legacy / Creative-Test campaign structure · audience & geo exclusions · scale-and-pause calls on a set weekly cadence.
You end up with A restructured account, a weekly reallocation rhythm, and a lower cost per outcome — usually visible inside the first month.
See a real example
At one publisher I shifted spend off underperforming geos and cohorts onto proven ones and split the account into Test / Legacy / Creative-Test. Cost per purchase dropped 43%, funnel ROAS rose 30% — and when the numbers said stop, I paused a $14K/day account back to $4K/day to stabilise before scaling again.

Step 03

Productize the winner

A result you can't repeat is luck. When something works, I write down why so your team runs it without me.

What happens I isolate the variables that actually drove the win and turn them into a named, written creative formula and testing loop.
Method Hook & format testing (UGC / AIGC / static) · demographic segmentation · variable isolation · documenting the winner as a reusable brief.
You end up with A creative playbook and a testing system that keeps producing winners after the engagement ends.
See a real example
A real-money skill-gaming app had no working creative. After hook and format tests I codified the winner — UGC, gameplay-first, an anti-scam hook, a small believable win, payment proof. Cost per purchase improved 57% from a zero baseline; install-to-purchase went from ~18% to 33%+.

Who I work with

A good fit

Consumer apps — gaming, fintech, subscriptions, D2C — past product-market fit, spending real money on Meta / Google / TikTok, and wanting the feedback loop to actually work.

Not yet

Pre-launch or pre-PMF products, sub-$5k/mo budgets, or teams looking for someone to just “run ads” without touching how success is measured.
