We work with teams building things that matter.
From early-stage startups to established global brands — we embed as a senior marketing partner, delivering strategy, brand, content, performance, and everything in between.
We don’t work with just anyone. And that’s intentional.
Great marketing requires genuine belief in what you’re building. Every client we take on is a team we believe in — tackling real problems, creating real value, and thinking long-term. That conviction is what makes the work better.

Frequently asked questions.
Everything buyers typically want to know before reaching out.
Stefka operates as an embedded extension of your team rather than an external vendor. We bring senior specialists who take full ownership of outcomes — not just deliverables. We are AI-native by design, meaning AI is woven into every stage of our work, from research and strategy to production and reporting. We work exclusively with mission-driven startups and scale-ups, so there is no cultural mismatch. And there are no account managers or unnecessary layers: you work directly with the people doing the work.
Most engagements start with a strategy sprint — a focused discovery and planning phase that gives us a clear picture of your goals, positioning, and market gaps. From there, we move into execution: a flexible mix of monthly retainer work and project-based deliverables. We assemble the right specialist team for each phase and adapt as your priorities evolve. Think of it as an in-house marketing team that scales with you.
Pricing depends on scope, team composition, and the level of ongoing support you need. Project-based work typically starts from €5,000, and monthly retainers range from €4,000 to €15,000 depending on the disciplines involved. Every euro goes toward senior execution — no account management fees, no overhead. We offer transparent pricing with clear scope boundaries. Reach out for a tailored proposal.
We typically work with early-stage startups through growth-stage scale-ups — companies that have product-market fit and need senior marketing capability without the overhead of a full in-house team. Most of our clients are between Series A and Series C, though we also partner with ambitious bootstrapped companies. If you are building something meaningful and need marketing that compounds, you are likely a good fit.
Once we have alignment on scope and objectives, we can typically begin within one to two weeks. The first step is a short discovery call to understand your situation and decide if we are the right fit for each other. If you have a specific launch deadline, let us know upfront and we will design the engagement around it. We move at startup speed.
We use AI across the full marketing stack. For strategy and content: Claude and GPT-4. For SEO and GEO intelligence: Perplexity and custom research agents. For creative ideation and visual concepting: Midjourney and Runway. For automation, reporting, and campaign optimisation: custom agentic workflows built around your stack. We are tool-agnostic and continuously evaluate what gives our clients the sharpest edge. The tools serve the strategy — never the other way around.
