Quiet strategy for
loud growth.

Six years owning enterprise SaaS and e-commerce portfolios across EMEA and APAC — first inside Amazon and Mindsite, now independently. I help brands enter new markets, scale the digital shelf, and turn distribution into a durable advantage.

01 — SaaS Growth

Compounding revenue, not louder marketing.

Six years of post-sale revenue ownership inside a venture-backed SaaS — 140% NDR, 0% logo churn on a ~$1M+ ARR book. I bring that operator playbook to founders and revenue leaders: sharpen pricing, fix the funnel where it leaks, design adoption and expansion programs that compound. The deliverable is always a working system, not a deck.

  • Post-sale revenue ownership: onboarding, QBR/MBR, upsell & renewal
  • Account health scoring and adoption playbooks that make retention predictable
  • ICP, pricing and proposal design — built on six years of $2K–$20K ACV deal work
  • Cross-functional squad leadership across Sales, CS, Product and Data

02 — Market Expansion & GTM

Enter a market on purpose, not by accident.

I have done this on the ground — APAC expansion out of Jakarta, MENA growth across four markets, DACH from Berlin. We start with 30+ buyer interviews, then write the local GTM: pricing, channels, partners, hiring, legal envelope, and the first 90-day operating cadence. No translated deck dressed up as a strategy.

  • Customer discovery: 30+ buyer interviews per market before a line of code moves
  • Local partner, channel and white-label deal scoping (done in Indonesia, MENA, DACH)
  • Hiring and onboarding the first SDR / commercial team on the ground
  • Localized sales & marketing collateral — EN, TR, Bahasa

03 — E-Commerce Growth

From shelf to repeat, with the math in writing.

I treat the storefront as a P&L — the way I learned it scaling a $17M Amazon vendor book and running digital-shelf programs for FMCG leaders like Hayat Kimya and Fine Hygienic. We work catalog economics, ad-driven contribution margin, availability, content compliance and retention together, so growth survives the next ad-cost spike or platform change.

  • Digital shelf: pricing, content compliance, availability and rating/review programs
  • Amazon vendor P&L work — deals, ads, assortment, Tier-1 event planning
  • Marketplace expansion across Trendyol, noon, Amazon, Q-commerce and Yemek platforms
  • PPC & retail media: ACoS / TACoS targets, bid and budget management across Amazon, Trendyol and noon
  • IDQ, A+ content and SEO consultancy — listing quality, keyword coverage and conversion optimization
  • Operational automation that saves 120–180+ hours/month of manual reporting

In their words

What partners say.

"
Denizhan rebuilt the way we manage our digital business. From pricing to availability, we now have full control and visibility across markets and platforms. The alert system and actionable insights have saved us time and directly contributed to our sales growth.
Director of E-commerce, Leading Gulf FMCG
"
He transformed our decision-making process, giving us a comprehensive view of markets, competitors and products. The work became essential to how we operate online — and the partnership keeps compounding.
E-commerce Sales SP, Leading Turkish FMCG
"
Calm, precise and deeply commercial. He treated our pricing and digital shelf like his own P&L — and stayed long enough to ship the work, not just diagnose it.
Pricing Lead, European Electronics Retailer
"
Denizhan is rare in this space — equally fluent with the data layer and the boardroom narrative. He helped us see our competitive position the way our customers see us.
Digital Commerce, Global Home Appliances Brand
"
The Restaurant Shelf Metrics work he scoped for us did not exist on the market. He wrote it down, built it, and held the cadence until it was running on its own.
Commercial, Global Beverages Leader
Methodology

Internal and external — looked at at the same time.

Most consultants look only at your data, or only at the market. I see both and tell you where the gap is. A four-stage framework, applied across all three solutions below.

01Day 1–2

Align

Where do you want to go? Without a target, analysis is meaningless.

  • 12-month growth target and priorities
  • Biggest current revenue blocker
  • Active channels and where investment is going
  • Strategy session with decision makers (1–2 hrs)
02Day 3–7

Diagnose

Internal and external data side-by-side to surface the real picture.

  • CRM & sales pipeline analysis — internal
  • Account docs and churn data — internal
  • Sector news, funding, competitor moves — external
  • Target accounts' hiring / firing signals — external
  • Market size and penetration — external
03Day 8–10

Prioritize

Not everything at once — where is the highest revenue impact in the next 90 days?

  • Revenue leak: churn, underpricing, wrong segment
  • Quick wins vs. structural bets
  • 90-day action plan with sequencing
  • Zero-resource vs. investment-required actions
04Ongoing

Execute & Track

I don't drop a report and leave. I stay on the execution.

  • Weekly 1-hour follow-up call
  • First actions launched together
  • Measure results, revise strategy when needed
  • Monthly progress report
The three solutions inside the framework

One method. Three engagement areas.

About

Denizhan Deniz

Previously at Mindsite & Amazon

I am an e-commerce and growth consultant based in Berlin. For over a decade I have built and scaled commerce operations across the EU, Türkiye and the Gulf — first as an operator inside two venture-backed companies, then independently.

I work with a small number of clients each year. Every engagement is led personally, written in plain language, and measured against the same number we agreed on day one.
