I fix the funnel leaks that waste your budget, and get them working in under 90 days.
I’m Maciej Turek, an independent growth consultant based in Amsterdam. I specialise in Customer.io and CRM implementation, lifecycle marketing, Answer Engine Optimization (AEO)/AI search, and Google Ads for SaaS and fintech companies across Europe. I’m listed in Customer.io’s Service Partner Directory. I have 15+ years of growth experience, including senior roles at bunq and Bitvavo, Dyme and OneFit. I also built AEO-Lite, a free AI-search visibility checker.

Most growth problems aren't about traffic volume. They're leaks: onboarding drop-offs, paid that scales in one market and wastes budget in the next, CRM flows that send while retention stays flat.
Those leaks rarely show up in a single channel report. I don't patch one channel in isolation. I line up acquisition, activation, and retention so fixes hold.
The process: find the leaks, run experiments you can measure, then scale what works. Target outcomes: lower CAC, higher LTV, faster payback.
The point is a growth system you can run, not another pile of channel tactics for the dashboard.
Most of my work clusters around three outcomes: stronger CRM and lifecycle performance, better AEO and AI visibility, and clearer growth architecture. I still support acquisition and AI-assisted execution where those outcomes move revenue, not activity for its own sake.
Hands-on implementation in Customer.io, Klaviyo, and Braze: segmentation, events and data logic, lifecycle triggers, retention, reactivation, and churn reduction.
Answer-engine optimization for AI Overviews, ChatGPT, Perplexity, and similar surfaces: schema and entity signals, answer-ready content structure, and commercial-page visibility.
Senior-level diagnostics across acquisition, retention, and experimentation: CAC, LTV, payback, attribution, and a prioritized operating rhythm.
Paid and organic performance where it supports the system, channel efficiency, creative testing discipline, and ROAS, without letting media spend outrun retention or measurement.
Generative creative testing, smart bidding, and predictive workflows only where they lift conversion or efficiency.
Structured CRO and activation work on signup, onboarding, and revenue paths, hypotheses, tests, and fixes grounded in behavior and unit economics.
Most engagements start with a free call, not a proposal. We'll figure out scope and fit before anything is signed.
Most projects fall into one of three buckets. Pick the one that's closest to what's broken. Engagement scope is tuned to the problem, not a tier.
Fix retention leaks, messy lifecycle logic, weak segmentation, and outdated CRM platforms. Customer.io, Klaviyo, Braze.
How your brand shows up in AI Overviews, ChatGPT, Perplexity, and answer surfaces, without turning the site into SEO sludge.
Clear POV across acquisition, retention, measurement, and experimentation, without hiring a full-time growth lead too early.
I've spent 15+ years doing the work in the tools, not only writing the plan. I still execute in CRM, ads accounts, and analytics, and I keep the work tied to board metrics like CAC payback and LTV. You get strategy and implementation without hiring a full team.
"With me, you don't get more tasks. You get a growth system you can run."
"Since we started working with Maciej, our business has undergone a significant transformation"
He introduced me to the essential principles of growth processes and offered hands-on support with specific projects and ideas that helped us regain momentum. He has the ability to consider all aspects, from team dynamics and company culture to processes, platforms, and technology. I highly recommend him.
"Maciej is a standout performance marketer who combines sharp analytical skills with a truly innovative mindset."
During his time at OneFit, he was not only deeply committed to our growth but also became a beloved member of the team. His hard work and ability to turn data into results make him an asset to any forward-thinking company.
"I've worked with Maciej on multiple projects and he always delivers."
He quickly identifies where funnels leak value and knows exactly how to fix it. Hands-on, no fluff, and great to collaborate with. For Resumedia and Renno, he built the analytics foundation we needed to make better product and growth decisions. Highly recommended.
30 minutes, free, scoped to your funnel. No deck, no pitch. You'll leave with three things you can act on this week, even if we never work together.

I'll show you the 3 specific points where you're losing the most money, with the numbers, and how I'd test fixes. You ask anything.
I send a 1-page summary: top 3 leaks, suggested experiments, rough scope if you want help. Yours to keep, share, or hand to anyone.
Book a quick intro call or send me a short brief. I'll review your funnel and reply with next steps, no fluff, no hard sell.
Share a few details about your product, traffic, and where you think the funnel is leaking. I'll reply personally within 48h.
