Hi, I help company owners and tech startup founders grow their businesses. A typical customer profile is a company with five figure monthly revenue and a strong will to grow, supported by appropriate budgets. I have 20+ years of leadership experience, including serving as Country Manager for Nokia HERE and graduating from the Alchemist Accelerator. I have raised $0.5M and closed a similar volume of commercial contracts in the AI and ML datasets sector. Finished a PhD in GIS Systems, founded several startups, and learned the hard lessons. Serial co-founder and investor, tech expert. I speak your language. Nothing to hide, nothing to polish. I help tech founders, manufacturers, and scale-ups navigate the complexities of international expansion and build systematic sales. My standard approach includes the following: 1. A 60-minute initial call to clarify needs and expectations. We decide if we see an opportunity to cooperate, how to design the process in general, and formulate expectations and budgets. 2. I conduct market research that usually takes two weeks and includes research into the appropriate niche and geo, a financial model, a marketing and GTM strategy, as well as a project plan. If you already have the above, we cut the scope. The typical challenges most founders face are data gaps regarding local business practices in the EU or a particular country, modern marketing methods, efficient sales strategies, and logistics. All of this should be clarified before we go all-in on the GTM. 3. Facilitation of the strategy in the form of concrete marketing and sales activities. This usually involves B2B sales activities using email, LinkedIn, and direct calls, GEO/SEO, AI search optimization, Meta Ads and Google Ads. Usually, you will see the progress in the first month. 4. We regularly meet and measure the results. Usually, it takes 4 hours a month from my clients. The GTM machine doesn't work without a driver, so this is a condition for success. What you can expect from me? 1. Direct and transparent communication. If a method or tool seems unsuitable for a given project, this is directly communicated. If the financial model is in the red, we try to change the approach or sometimes simply stop cooperation, which usually happens due to a lack of funds or an underestimation of project complexity. 2.Corporate-level project management and quality. Just like my clients such as Nokia, larger retail companies, or private SMEs, you can expect the same top-class service approach from me. 3. Honesty and problem prevention on my part. You will know about issues early on and save money with me. What is not of interest to me: 1. One-off test projects. 2. Slow decision-making. 3. Low-cost assignments.
