Natalia Tonenka:<\/strong> I\u2019m a marketing leader with over 16 years of hands-on experience in product-led tech companies across Ukraine, Europe, the US, and Southeast Asia. Before the full-scale war I built and ran marketing for Rocket, Moneyveo, Innovecs, Prom.ua, Foxtrot and a few others, usually coming in to create departments from zero, launch new brands, and deliver aggressive growth. My favorite war stories: taking Rocket to 45% market share in Ukraine in the first six months and successfully rolling out two completely new financial products for Moneyveo. <\/p>\n\n\n\n When the war started I moved with my family to Germany. In Berlin I first worked as a marketing strategist in a local agency, then stepped in as fractional CMO for a big Ukrainian logistics player to lead their German launch. In six months we brought in 200,000+ new users and took 3rd place at the Berlin Ecommerce Awards for the fastest expansion of the year. <\/p>\n\n\n\n I also tried building my own AI mental-health startup here, but closed it on purpose, I simply don\u2019t want artificial intelligence poking around in people\u2019s heads. Some things have to stay human. Now I run my own consulting practice and small agency, helping EU- and US-based startups build predictable marketing machines and scale internationally. Ukrainian reality trained me to operate in permanent turbulence; four years in DACH gave me deep local know-how. Put those two together and you get someone who can find growth fast, even when everything feels shaky, because shaky has been my normal for a very long time.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> First of all, I\u2019ve been on the receiving side many times. Mentors literally shaped my career, pulled me out of dead ends, and gave me the shortcuts I needed. I owe them a lot. Then I started mentoring marketing specialists who wanted to become heads of departments or CMOs. I quickly realised I genuinely love teaching: I ran a strategic marketing course for aspiring CMOs, taught digital marketing to Ukrainian refugees in Germany who were switching careers, and saw people land their first jobs here because of it. When I was building my own (now closed) AI mental-health startup, dozens of people gave me their time and advice for free. <\/p>\n\n\n\n The world runs on this simple rule: if you take, you give back. Mentoring startups is exactly that payback, plus I learn something new every single session. I get a front-row seat to projects that can actually change the world, and the energy I get from founders who are ready to move mountains is priceless. So for me mentoring is not charity work. It\u2019s career oxygen, a way to stay sharp, and the best reminder that the knowledge in my head is only valuable when it helps someone else fly.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> For me, real progress at the early stage is when the team stops \u201cinventing\u201d and starts truly hearing their users. I know things are moving forward when: they\u2019ve done proper custdev interviews and can articulate the problem and value in their customers\u2019 own words \u2014 not their own assumptions. The business model is clear: they know exactly how much money they need, for what, when they\u2019ll break even, and why an investor should care. There\u2019s a realistic roadmap, a working MVP, a live website\/app, and the first real users, customers or partners are already in. <\/p>\n\n\n\n The team is gradually filling the right roles. And the things I always pay closest attention to: how fast the founders can kill their favourite hypotheses (the best ones kill 8 out of 10 ideas before even testing). Whether they measure absolutely everything they possibly can, even if the dashboard is still tiny. Whether the product solves a problem people are willing to pay for right now \u2014 not \u201cin two years once the market is ready\u201d. When all of this is in place, I know the startup is alive and heading in the right direction.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> I bring 16 years of hands-on marketing experience from both chaotic Ukrainian startups and big corporations, plus 4 years of scaling in the rule-heavy DACH environment and my own (now closed) AI startup. This mix \u2014 startup survival mode, corporate discipline and the very fresh memory of being a founder myself \u2014 is what I use every mentoring session. It helps early teams spot fatal mistakes before they burn cash, build investor-ready metrics from day one, and separate \u201ccool idea\u201d from \u201cpeople will actually pay for this right now\u201d.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> The biggest problem I see over and over again is that founders fall in love with their solution instead of falling in love with the customer\u2019s problem. Most teams are terrified of talking to real people, so they guess, run superficial surveys at best, and end up launching yet another \u201cme-too\u201d product nobody truly needs. I fix this first: I give them simple, battle-tested scripts and techniques to find the right people, get them on a call, run proper depth interviews, and actually hear the pain in the customers\u2019 own words. Once they have 15\u201320 real interviews, the product direction usually changes 180\u00b0 \u2014 and for the better. <\/p>\n\n\n\n The second classic trap is money blindness: founders don\u2019t know how much to ask from investors, how to calculate a realistic marketing budget, or which metrics actually matter. I walk them through unit economics from day one, build the first financial model together, and teach them to measure everything that moves. Suddenly the pitch stops being \u201cwe have a cool idea\u201d and becomes \u201chere\u2019s the exact problem, here\u2019s proof people will pay, here\u2019s how we get to breakeven in 14 months\u201d. The result? Investors stop seeing dreamers and start seeing future business owners who already think (and speak) like CEOs. That\u2019s exactly how I help early teams turn vague excitement into a product customers want and a story investors can\u2019t ignore.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> Data-driven isn\u2019t a religion for me \u2014 it\u2019s a tool that has to be used at the right moment. At the very early stage (pre-sales, pre-PMF), there simply isn\u2019t much meaningful data to track. Trying to be \u201cdata-driven\u201d when you have 30 sign-ups is pointless and often paralyzing. At this point I look at one thing only: how fast and purposefully the team is moving along the roadmap, how quickly they test hypotheses and talk to real people. Speed of learning beats any dashboard. As soon as the first sales appear (even \u20ac100\u2013500 a month), everything changes. <\/p>\n\n\n\n From that moment on we start tracking the key metrics at least in Excel: CAC, LTV, payback period, retention cohorts, conversion rates. Once these numbers are stable for 2\u20133 months and we understand what actually works, we build automated dashboards (Amplitude, Mixpanel, whatever fits the budget). My rule is simple: before first revenue \u2192 focus on speed of customer interviews and hypothesis killing. After first revenue \u2192 every euro and every day must be measured. Use data when it actually exists and can protect you from big mistakes.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> In my experience the balance isn\u2019t 50\/50 \u2014 it\u2019s 80\/20 in favour of product until you have repeatable sales, then it flips to 50\/50 and eventually to 20\/80 when you\u2019re scaling aggressively. Pre-PMF (no repeatable sales yet): 80% product\/build + 20% marketing\/validation. Marketing\u2019s only job is to bring real user feedback as fast and as cheaply as possible. Everything else is waste. First 10\u201350 paying customers: 50\/50. Product keeps solving the core pain, marketing starts building the first predictable channel and proves unit economics. Post-PMF, growth stage: 20% product (iteration + retention) + 80% marketing\/sales. <\/p>\n\n\n\n At this point the bottleneck is almost always distribution, not the product itself. I\u2019ve seen dozens of startups die because technical founders kept polishing the product for months while marketing was \u201csomeone else\u2019s job\u201d. And I\u2019ve seen the opposite \u2014 marketing burning cash on a product nobody wanted to pay for. The right ratio is brutal but simple: marketing weight must grow exactly in proportion to proven demand. No proven demand \u2014 no big marketing. Proven demand \u2014 marketing eats the oxygen.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> I support founders with limited resources simply by giving them everything I already have \u2014 for free. Ready-to-use tools from my 16 years that actually worked: customer interview script (15 questions that reveal real pain in 25 minutes), one-page Lean Canvas template I used for my own startup, one-page GTM plan that fits on an A4 sheet, simple unit-economics Excel that shows runway and breakeven from day one, pitch-deck structure that helped my teams raise money more than once. No theory, no paid courses, no \u201ccome back when you have budget\u201d. Because I know exactly how it feels when there is no money yet, and every wasted day is critical. My job is to remove weeks of reinventing the wheel so they can start testing and talking to real users tomorrow morning.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> Pioneers Club is one of the few communities in Germany that genuinely accelerates the path from idea to real funding. For startups it delivers hand-picked, battle-tested mentors who\u2019ve already built and scaled what the founders are fighting for, direct matchmaking with active angels and VCs (including access to exclusive events and free tickets to top conferences where investors actually show up), a credibility badge that instantly attracts talent, partners, and follow-on interest. For mentors and talents like me it\u2019s the best place to stay sharp, spot the strongest teams early, and sometimes join or co-invest. In short: the Club shortens the distance between \u201cbuilding in stealth\u201d and \u201cstanding in front of the right investor\u201d \u2014 dramatically.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> I\u2019m not sure I can give a strong answer here, because in the startups I\u2019ve mentored so far the opposite has happened: new co-founders actually joined the teams, and nobody has left yet. But of course, if a founder does decide to move on, Pioneers Club makes the next step very natural. There\u2019s an active job board where founders openly post exactly who they need (CTO, CMO, Head of Growth, etc.), and the network quickly connects the right people.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> The startup landscape has shifted dramatically over the past few years: from the \u201cgrowth-at-any-cost\u201d era to a much more disciplined, niche-focused, and sustainable reality. Markets reward deep specialization instead of universal platforms, user expectations have skyrocketed (personalization, trust, data safety, and seamless mobile experience are now table stakes), and company structures have become leaner, remote-first, and heavily AI-augmented. Investors pour money only into teams that prove strong unit economics early and embed responsibility (ethical AI, sustainability, transparent data use) into the core of the product from day one. <\/p>\n\n\n\n For new founders my advice is simple: stop chasing trends \u2014 solve a painful problem you truly understand, talk to real users weekly, build trust and retention before aggressive acquisition, and use AI as a force multiplier, not as a buzzword. The winners in 2025\u20132026 are the teams that combine ruthless focus on real customer value with clean numbers and a culture that can pivot overnight. Everything else gets filtered out fast.<\/p>\n\n\n\n Natalia Tonenka:<\/strong> I\u2019m genuinely optimistic about the DACH startup scene: we have the engineering talent, the capital is rising, and real strength in deeptech, fintech, greentech and healthtech that solve big, painful problems. Three things will decide whether we become a true global powerhouse or stay \u201cvery good but not explosive\u201d: mentoring \u2014 it already saves founders 6\u201312 months, turns first-time founders into second-time founders without the scars, and opens direct doors to investors and corporates. <\/p>\n\n\n\n Diversity \u2014 the more women, immigrants, and non-traditional backgrounds we have in founding teams, the faster we create products that work globally and the higher the creativity and resilience of the entire ecosystem. Bureaucracy \u2014 the only real brake I see today; endless paperwork and slow processes for visas, funding programs, and even simple company registration still scare off too many international talents and slow down capital flow. Fix that one bottleneck, keep pushing mentoring, diversity and strong marketing, and DACH will start producing global category leaders on a regular basis.<\/p>\n\n\n\nWhat made you join Pioneers Club as a mentor, and why does mentoring matter to you personally and professionally?<\/h3>\n\n\n\n
