AI | Go-to-Market Systems | Growth | Leadership
Tunahan Yildiz
I build and scale go-to-market systems, teams, and processes, most recently leading DAC’s DACH business development from scratch and creating a new eMobility vertical.
Earlier, I co-founded two companies, grew operations teams, and drove expansion for international brands across industries.
My focus: making growth scalable, processes efficient, and strategy executable. Always open to exchanging ideas and learning from others.
My Background
At 20, I built my first company, developing macros for mobile games and monetizing the process. Three years later, I exited, selling both the company and its automation framework.
I went on to co-found two ventures:
-
AdOlymp: developed in-house tracking technology for affiliate marketing.
-
SwishOver: a performance marketing agency focused on mobile growth through affiliate and programmatic channels.
At 24, I stepped into my first leadership role at SoHype, managing a global team of eight account managers and shaping growth operations at scale.
Later, I joined StackAdapt as the first German-speaking Account Executive, where I closed foundational deals that established a strong foothold for the company in the DACH market.
Today, I serve as Director of Business Development at DAC Group, where I built the DACH sales operation from the ground up and launched a new eMobility vertical, positioning the agency as a key partner in the region.
I enjoy building systems, scaling teams, and exploring how strategy turns into execution. Always open to exchanging ideas, let’s connect.
What I Focus On
Go-to-Market & Growth
I design and scale go-to-market systems that align strategy with execution. This includes building sales operations, setting up outbound and inbound structures, and positioning new verticals in competitive markets.
AI & Automation
I explore how AI creates business impact. From practical tools to tailored workflows, I focus on embedding automation into decision-making and processes so teams can move faster and smarter.
Leadership
Strong leadership means enabling others. My focus is on decision-making, efficient execution, and building systems that empower teams. I bring in management practices that improve workflows and support sustainable growth.
Strategy Execution
I work on bridging the gap between planning and doing. This means aligning resources, managing risks, and ensuring outcomes are measurable and sustainable.
Negotiation Mastery
I see negotiation as a way to create lasting value. My experience includes securing market entry deals, managing complex partnerships, and driving alignment across teams and stakeholders.
Operations & Process
Behind every successful team is a strong operational backbone. I build frameworks, workflows, and measurement systems that improve accountability, increase efficiency, and scale across regions.
