Hello, my name is Diana Kósa.
With nearly 20 years of experience in international business – from marketing strategy and operations to leadership and production processes – I help entrepreneurs and businesses turn ideas into structured, working solutions.
No false promises – just clarity, direction, and well-built systems that work for everyone involved.
I also lead my own business projects, open to collaboration with strategic partners, professionals, or investors.
I’m a strategic thinker who sees both the details and the bigger picture.
Over the past 15+ years, I’ve worked across marketing, business development, production systems, and leadership – in both corporate and entrepreneurial settings.
I connect ideas with execution. I bring structure, insight, and a clear path forward – and I often do this not alone, but together with other driven partners.
I value practical outcomes, shared success, and long-term thinking. If you do too, we might be a great match.
Nexacon (strategic marketing execution), Synercon (process development), Marketing Insider (content & community).
Lokal marketing and operations lead at Wacker Neuson Slovakia – strategy, human resources initiatives, efficiency improvements.
Implementing strategies to improve the customer experience and satisfaction. Internal/external corporate comms, branding, NPS, leadership.
Roles in production and business operations at Schindler – including process optimization, SAP rollout, KPI frameworks
Working independently in marketing, brand design, and business communication
Alongside consulting and strategic work, I also launch and lead my own business and collaborative projects.
Some are early-stage concepts open to collaboration – where I’m actively looking for professionals, partners or investors to co-create and grow something meaningful. Others are case studies that reflect how I work: combining strategic thinking with practical execution in marketing, operations or business development.
If you’re looking to connect, collaborate or contribute, this is a great place to start.
I don’t sell templates.
I think with you – and build with you.
Whether you’re stuck or ready to launch something new, I bring structure, clarity, and forward motion.
Here’s what working with me usually looks like:
Discovery
We start with a deep dive into your idea, challenge, or current state. I ask, listen, and analyze.
Direction
We define a strategic direction: what to focus on, where to go, and why it matters.
Structure
Together we outline what's needed: website, messaging, offer, branding, process – step by step.
Execution
I either bring my team (via Nexacon) or support you in executing with your own resources.
