Toprak Hürriyet · Fintech Growth Consultant

Background

Three years inside a regulated growth engine.

I advise founders and growth leads on where acquisition budget is actually working — I step in when CAC is climbing, attribution is unclear, or a board wants numbers that hold up under scrutiny.

I run performance marketing for İşCep, the mobile banking app of Türkiye İş Bankası, one of Turkey's largest banks. The mandate: new customer acquisition, credit card issuance, and payment-product growth, measured through event-based tracking in Adjust, not surface-level clicks.

Operating inside a compliance-heavy environment forced the work to go deep rather than wide: event taxonomy, in-app conversion mapping, funnel diagnostics. That depth carries directly into Meta, Google, and TikTok campaigns for fintechs operating with fewer restrictions.

I started advising fintechs outside Turkey because the same problem kept showing up: teams spending confidently on channels they couldn't actually verify. Regulated growth taught me to distrust a number until it's traceable to a real event — that's the standard I bring to every engagement.

Case Study

Turning a compliance-heavy funnel into a measurable one.

Challenge

A large regulated banking app was running paid acquisition across multiple onboarding and card products, but spend and conversions weren't cleanly mapped to real events — so budget decisions were being made on incomplete signal.

Approach

Rebuilt the event taxonomy in Adjust product by product, closed gaps in in-app conversion tracking, and reallocated spend toward the channels and campaigns that traced to verified conversions.

Services

Two ways to work together.

Find out where your acquisition budget is actually working, or bring me in on retainer to grow funded accounts end to end.

Funnel Audit

Fixed scope, 2 weeks

Find out which channels are actually acquiring profitable customers, and which ones are quietly inflating your CAC. You'll get a clear, defensible view of what to cut and what to scale.

Growth Retainer

Monthly, scope-based

An acquisition partner, not an execution hire. I run strategy and hands-on execution across your primary paid channels, so budget moves toward what's provably working.

Lower CAC and more funded accounts, tracked monthly
Direct account execution, not a handoff to someone else
Monthly review call and written performance readout

Discuss a retainer

Creative production isn't part of either offer. I work with your existing creative or design team, not in place of one.

Lower CAC.
More funded accounts.
Numbers your CFO trusts.
