OMER OZBEY · ABOUT · 01
A 60‑second snapshot.
Three business models. Seven industries. One method.
I’m a digital marketing specialist who has spent three years owning full-funnel growth across B2B, B2C, and D2C accounts, including public-sector defense procurement, industrial B2B (marine, EMS, IoT, product design, experience), consumer entertainment, and indie gaming. The business models and industries look unrelated; the discipline underneath isn’t.
I apply my PhD in Critical Thinking directly to the work: surfacing the assumptions behind a campaign or a metric, then drawing conclusions from the data in front of me rather than from the assumption I started with.
How I Work
- 01Every campaign starts with a clear number to hit, and a plan for what happens if it doesn’t.
- 02Channels follow the audience. The audience never follows the channels.
- 03A small, well-measured test beats a big launch full of opinions.
- 04If I can’t explain a metric to a non-marketer, I don’t trust it yet.
- 05AI accelerates the work. It doesn’t replace the thinking.
B2B · Defense, Marine, EMS, IoT, Product Design, Experience
Demand generation across six B2B industries at INFINIA, including public-sector defense procurement. Shared lead-scoring, unified attribution.
B2C · Entertainment, Indie Gaming
Consumer demand generation for INFINIA’s entertainment vertical and Oba Games’ Steam launches: wishlist scaling, creator programs, community management.
D2C · Subscription & E-Commerce
Direct-to-consumer growth for Marisonia’s original marine-subscription motion and 8 freelance D2C/e-commerce clients: paid social, lifecycle email, CRO.
B2B · Defense, Marine, EMS, IoT, Product Design, Experience · 2025 · INFINIA MÜHENDİSLİK
Running one demand-generation system across six B2B industries with different buyers, budgets, and sales cycles.
A unified paid-media and lead-scoring program spanning public-sector defense procurement, marine dealer networks, EMS, IoT, an experiential franchise business, and product design. Held a 24% lead-to-MQL rate and a 26% MQL-to-SQL rate across all six industries, with a blended pipeline-to-spend ratio above 25x.
The Challenge
INFINIA is a multi-vertical engineering firm: defense systems sold to government and public-sector buyers, marine products sold through dealer networks, EMS and IoT sold to industrial buyers, product design sold as custom engineering work, and an experiential franchise business. Six industries, six buyer types, six sales cycles, one marketing seat. There was no shared lead-scoring model and no shared attribution, so a $310 defense cost-per-lead and a $92 marine cost-per-lead sat side by side with no way to tell if either number was actually good.
The Approach
- 01Built a shared lead-scoring framework, calibrated per industry.Defined what MQL and SQL meant for each buying committee (procurement officer, boat dealer, franchise operator), then tracked conversion at each stage on a consistent basis across all six.
- 02Ran paid media through the channel each industry’s buyer actually used.Google and LinkedIn ABM for defense and industrial buyers, Meta and search for the experience franchise business. A distinct channel mix per industry instead of one blended paid strategy.
- 03Layered email and organic nurture underneath every paid channel.Built lead-nurturing flows and an SEO content engine running in parallel to paid across industries, then compared cost-per-SQL across channels to find where the real efficiency was.
- 04Built one dashboard covering all six industries.GA4, GTM, and CRM data unified with consistent UTM governance, so a defense MQL and a product-design MQL used the same measurement logic even though nothing else about them was the same.
- 05Reallocated budget toward the industries and channels the data actually supported.Once a full data cycle existed, shifted spend toward Product Design, the strongest MQL-to-SQL converter, and away from underperforming IoT paid search.
The Results
Across the six B2B industries, the programme converted leads to MQL at roughly 24% and MQL to SQL at roughly 26%, both above the 13–20% B2B benchmark, with a blended pipeline-to-spend ratio above 25x. Performance varied meaningfully by industry: Product Design converted MQL to SQL at 37%, the highest of any industry, while Defense produced a 56x pipeline-to-spend ratio on the strength of its deal sizes rather than its conversion rate.
On the channel side, email and organic nurture converted MQL to SQL at roughly 45%, at a cost-per-SQL eight to ten times lower than paid social or search, evidence that the highest-value channel wasn’t the one getting the largest budget. Entertainment, INFINIA’s B2C vertical, sits outside this blended B2B figure and converted at a materially different rate (close to 84% MQL-to-SQL) at a fraction of the cost-per-lead, a reminder of how much the funnel math changes once the buyer isn’t a committee.
Where It Didn’t Work
IoT paid search underperformed for most of the period: a $410 average cost-per-lead against a sub-19% MQL-to-SQL rate made it the least efficient industry in the portfolio by a wide margin. Rather than keep optimizing bids, the honest call was to shrink IoT’s paid budget and lean on the channels already outperforming it everywhere else.
What I’d Do Differently
I’d have built the cross-industry lead-scoring framework in month one instead of month four. Early numbers weren’t comparable across industries because MQL didn’t mean the same thing in each one yet, and it took a full data cycle to fix that retroactively.
Cross-Functional Reach
Weekly coordination across engineers, designers, and sales teams in INFINIA’s Ankara, Istanbul, Amsterdam, Manchester, and Doha offices, translating technical product features into industry-specific marketing assets and lead-gen funnels across all six B2B lines, plus entertainment.
Channels & Stack
D2C → B2B2C · Marine · Aegean + Mediterranean · 2025 · INFINIA MÜHENDİSLİK · Marisonia
Pivoting a marine subscription product from D2C to a partner-led distribution channel.
Held 3.2× blended ROAS across €69.99 to €159.99 plans while onboarding 12+ boatyard and charter partners across the Aegean and Mediterranean.
The Challenge
Marisonia is INFINIA’s marine vertical: a subscription product for boat owners and charter customers across the Aegean and Mediterranean. The D2C paid-acquisition motion was scaling but bumping against unit-economics ceilings. CAC was creeping up as the addressable consumer segment narrowed, and the product’s seasonal usage pattern (April to October peak) made retention harder than annualized subscription benchmarks. A second acquisition channel that wasn’t paid social was needed.
The Approach
- 01Built the partner economics model first.Worked through CAC arbitrage with finance: at what revenue-share rate did partner-acquired customers beat paid-acquired ones on contribution margin after factoring expected retention curves. Got to a defensible ratio before writing the first outreach email.
- 02Identified ~50 target partner accounts.Filtered by partner type (boatyards, charter operators, sailing schools), geographic concentration in existing paid hotspots, and adjacency fit with their service offering.
- 03Designed co-branded landing pages with partner-specific UTMs.Each partner got a dedicated landing page with their branding and a unique tracking parameter, so partner contribution was attributable to within roughly 5%.
- 04Repositioned D2C paid as the category-education channel.Reduced direct-response intent, raised brand and education content. Goal shifted from “convert immediately” to “be the obvious choice when a boatyard mentions us.”
- 05Migrated lifecycle email to handle partner cohorts separately.Different onboarding flow, different upsell timing aligned with partner relationships.
The Results
12+ partners onboarded across Aegean and Mediterranean ports in two quarters. Blended Meta + Google ROAS held at 3.2× across €69.99 to €159.99 plans through the pivot from D2C toward a B2B2C partner model, meaning D2C paid stayed efficient while the partner channel scaled in parallel. The acquisition mix shifted without breaking unit economics.
Internal · Marketing Ops · B2B + D2C + B2C · 2025 · INFINIA MÜHENDİSLİK
The marketing operations infrastructure that lets one specialist run three accounts across three business models.
A unified content production workflow, cross-account attribution architecture, and AI-augmented editorial system supporting the defense account, Marisonia, and XPZONE, compressing content cycles 40% and saving 6+ hours weekly.
The Challenge
One marketing function, three flagship accounts across three different business models: defense (B2B, public-sector buyers), Marisonia (D2C), and XPZONE (B2C/B2B experience). Different audiences, different sales cycles, different stacks, different languages. Without infrastructure, the marketing role would collapse into reactive triage: produce a brief, get it translated, ship the campaign, scramble to assemble reporting, repeat. There would be no time for strategy.
The Approach
- 01Built an AI-augmented content workflow.ChatGPT and Claude for brief drafting, EN/TR translation, and editorial QA, with strict brand-voice guardrails. Defense-sector copy needed human review at three points (technical accuracy, tone, compliance); consumer copy needed lighter editorial.
- 02Codified brand voice per account as reusable prompts.Documented voice (defense formal, marine consumer warm, XPZONE specific) so AI outputs hit the right register before human editing. Reduced rework time per piece by roughly half.
- 03Architected unified attribution across all three accounts.GA4 + GTM + Looker Studio + HubSpot CRM with consistent UTM governance, so the same parameter conventions worked for B2B LinkedIn ABM, D2C Meta retargeting, and internal campaigns.
- 04Built one Looker Studio dashboard collapsing three reporting workflows.Previously three separate spreadsheets, three weekly reports, three stakeholder conversations. After, one dashboard with account-level views and a cross-account summary, one weekly meeting cadence.
- 05Codified the production process.Briefs, asset library, approval workflows, publishing checklist, written down once so it didn’t have to live in my head.
The Results & the Second-Order Effect
~40% content cycle compression (briefs that used to take ten days ship in six, with quality controls intact). 6+ hours per week saved on reporting, reinvested into channel testing and strategy. 3 accounts across 3 business models on one unified system that scales with marginal complexity. The infrastructure is what made the defense ABM programme possible: without it, there was no time for 80-account campaigns.
B2C · Indie Gaming · Steam · Feb 2023 to Mar 2024 · Oba Games · Hakan’s War Manager
Scaling a PC strategy game from <500 to 22,000+ Steam wishlists before Early Access.
A 13-month go-to-market built on creator partnerships, Steam Next Fest positioning, multilingual store optimization, and a community-first content engine on TikTok and YouTube Shorts.
The Challenge
Indie strategy games live or die on wishlist velocity before Early Access. Storefront conversion, the Steam algorithm’s “trending wishlists” surface, and launch-day visibility all depend on it. Hakan’s War Manager entered my hands with fewer than 500 wishlists, a generic store page, no creator outreach, and no community. Early Access was 13 months out.
The Approach
- 01Storefront CRO as foundation.Iterated capsule art, “About this Game” copy, trailer hook, and screenshot order, A/B-tested against control periods to track visit-to-wishlist lift independent of traffic spikes.
- 0240-creator program in strategy-game niches.Mid-tier YouTubers and Twitch streamers in grand-strategy and war-management, with custom early-access keys and tiered post-coverage attribution.
- 03Steam Next Fest as the anchor event.Coordinated demo build, livestream schedule, and creator coverage around the festival, the single highest-leverage moment for wishlist velocity in the Steam calendar.
- 04Organic short-form on TikTok and YouTube Shorts.Hooked on in-game moments and dev commentary. 1.2M+ organic views, with the strongest converters re-cut into store-page trailer variants.
- 05Localization into Turkish, German, and Simplified Chinese.Storefront and trailer subtitling, prioritized by historical Steam audience data, contributed 31% of total wishlists from non-English regions.
The Results
The campaign closed at 22,000+ wishlists pre-Early Access, a 44× lift. Store visit-to-wishlist lifted from 8.2% to 14.6%, meaning the same traffic produced 1.78× more wishlists per visit. Community-driven inquiries that converted to direct sales doubled. The 1.2M+ organic short-form views ran on a near-zero paid budget: the unit economics of indie GTM made organic creator content the only viable acquisition path, and it worked.
B2B · SaaS · San Francisco, CA · Apr 2024 to Feb 2025 · Turquoise Choice · PB360.me
Building a full-funnel growth engine for a pickleball SaaS across web, iOS, and Android.
From $0 to $8K/month in paid spend, 2.1K to 28K monthly organic visitors, and a Play Store rating from 4.1 to 4.6, across the fastest-growing racquet sport in North America.
The Challenge
Turquoise Choice operates PB360.me, pickleball events and league-management SaaS for North American clubs and tournament organizers. The sport was scaling fast; the platform’s marketing wasn’t. Paid was at zero, the SEO engine didn’t exist, the apps had no lifecycle email, and Play Store sat at 4.1. I joined as the first dedicated marketing hire and owned the full funnel for web plus iOS and Android.
The Approach
- 01SEO content engine at 15+ articles per quarter.50+ articles in 9 months targeting tournament-organizer and league-manager search intent, with internal linking and topical clustering.
- 02Meta and Google Ads scaled $0 to $8K/month.Systematic creative testing on hooks, formats, and audiences, with retargeting flows that doubled weekly signups and pulled CAC from $14.20 to $11.05.
- 03ASO across iOS and Google Play.Keyword optimization, screenshot iteration, and listing copy refinement drove a 41% organic install lift and moved Play Store rating from 4.1 to 4.6.
- 04Klaviyo lifecycle infrastructure.Welcome, activation, and re-engagement flows that lifted 30-day retention by 27% and strengthened activation-to-paid.
- 05Weekly A/B testing on landing pages and email creative.GA4 + Hotjar insights driving MAU growth of +15% across the 9-month engagement.
The Results
Over nine months, organic visitors grew from 2,100 to 28,000 per month, five high-intent commercial keywords ranked on Google’s first page, paid CAC dropped 20%, weekly signups doubled via retargeting, and 30-day retention lifted 27%. Play Store rating moved 4.1 to 4.6, organic installs lifted 41%, and MAU grew 15%.
ADDITIONAL ENGAGEMENTS · 06
Earlier independent practice.
Before the in-house roles, two years of freelance.
Freelance · Multi-Client · D2C & B2B
SMB & D2C performance marketing across 8 clients · Türkiye + International · Jan 2022 to Jan 2023
Operated $120K+ in annual paid media across Google Ads and Meta for 8 SMB and D2C clients spanning e-commerce, SaaS, and local services. Each engagement included a technical SEO audit, GA4 + GTM setup, and Klaviyo or Mailchimp lifecycle flows with Hotjar-driven CRO testing. Working independently across this many accounts is where the production discipline came from that later made it possible to run multiple industries at INFINIA: the same questions kept appearing across clients, so the answers got systematized instead of re-derived each time.
Selected Operational Highlights Across Roles
Multilingual SEO at Scale
Built EN/TR content hubs ranking page-one for 45+ commercial keywords across defense, marine, and internal accounts.
Cross-Cultural Localization
Localized assets into Turkish, German, and Simplified Chinese for indie gaming, contributing 31% of total wishlists from non-English regions.
Lifecycle Email Infrastructure
Built Klaviyo flows that lifted 30-day retention 27% for SaaS, and segmented partner-acquired vs. D2C cohorts in marine.
Creator-Led GTM
Ran a 40-creator program across YouTube and Twitch for indie gaming, contributing to a 44× wishlist lift before Early Access.
App Store Optimization
Drove a 41% organic install lift and moved Google Play rating from 4.1 to 4.6 through keyword work, screenshot iteration, and listing copy.
Cross-Functional Collaboration
Worked weekly with engineers, designers, and sales across five INFINIA offices (Ankara, Istanbul, Amsterdam, Manchester, Doha).
A Note on What’s Not in This Portfolio
A few engagements are excluded for confidentiality, particularly under NDA on the defense side, and partner-protected work in the marine vertical. Specific account names, budget breakdowns, and creative samples are available under NDA in interview.
