Growth Strategy Consultant / Head of Growth Marketing
I've run +560 A/B/n tests and reached ~35% success rate. Based on my experience, CRO and experimentation are the most impactful business activities to make your company succeed. By challenging your product-market fit and testing different funnels or versions of your landing page/your communication/platform/service, you can get game-changing uplifts in conversion rate and the PMF score.
While consulting to +30 companies, I worked with tens of MarTech tools and I can help you select the best tool stack for your company. Examples: Google Analytics, most of paid ads platforms, Google Tag Manager (HTML, CSS, JS), Google Optimize, VWO, Google Data Studio, PowerBI, Unbounce, Instapage, Webflow, Hubspot, Pipedrive, Clearbit, Zapier, SEMRush, SpyFu, Similarweb, Ahrefs, AppAnnie, AppsFlyer, WordPress, Mailchimp, Freshsales, Magento.
For ~2 years I've been managing growth hacking team in the biggest growth marketing agency in the world - Ladder.io. By working directly with C-level executives I've been consulting, creating and implementing growth strategy by testing and scaling marketing tactics that increase ROI across every channel.
I've been running a complete process of PPC campaigns creation and optimization for both startups validating their business model and tech giants scaling their profit. I've always been optimizing for maximizing ROI, I've spent $8.7M across Facebook, Google, LinkedIn, Twitter, Taboola, Reddit, Apple Ads, Snapchat and Tinder.
Well designed Facebook campaigns can bring you +1000% ROI. I'm in the process of Facebook Marketing Consultants certification. I've been running campaigns from $1k monthly budget and scaling them to international expansions with $300k monthly budget. It was a challenge most of the marketing gurus have only read in books - I can help you with it practically. I've spent +$3m in B2B and B2C campaigns, always optimizing for maximizing ROI.
I'm certified in LinkedIn Advertising by CXL Institute. By spending +$200k in this ad platform, I've learned what works and what doesn't. I can help you set up ROI-positive campaigns and avoid costly mistakes I've made.
I'm certified by Google in Search and Display networks. I've been running all types of international campaigns in Search, Display, App, YouTube, Gmail. I've spent +$1.5m in B2B and B2C campaigns, always optimizing for maximizing ROI.
Google Optimize, after a few major updates in the last 3 years, became my favourite tool for A/B/n tests. It's free, extremely powerful and very intuitive. I can help you set up your experiments and fix what's not working.
Zapier is the tool that unleashes the potential of data and processes integration. I use it for automating the whole marketing and reporting process with the most tools available in the market. I can help you with the setup, as more advanced integrations aren't so easy to do.
My primary tool for designing landing pages for my clients. With +200 pages set up by Unbounce and a blog post about how my agency has been using it, we've got a hand-written letter from the CEO thanking for the cooperation.
Semrush is one of the most useful tools in my tool stack for competitors research, marketing insights and gap analysis. I use it for both paid and organic channels analysis. Especially good for US&UK markets.
I'm using Google Search Console for SEO purposes (both technical and analytics) and it's one of the most important tools in my tool stack. I can help you with implementation and understanding the full potential of GSC.
I've set up tens of dashboards for my clients and made it the main reporting tool for their businesses. I can help you with any setup or connecting all your business' data sources like GA, paid ads platforms, CRM, email campaigns, cloud databases.
Most of my US clients have been using Hubspot so I had to learn it - I loved it in the end. I'm a big fan of making Hubspot a basic version of a Customer Intelligence tool by using CRM and Analytics products together. I can help you with proper implementation and even using it as a CMS (but there are much better tools for it).
GTM should be the best friend of every growth marketer and lean expert who wants to implement changes in the product fast, without waiting weeks for developers to implement a code. It's the tool I install for each of my clients and I can help you with most of the implementations (HTML, CSS, JS).
Hotjar was game changers for me when I started learning about UX and CRO. After hundreds of hours of recordings watched, understanding of your customer behaviours and their intentions grows significantly. Always the 1st tool recommended when starting a qualitative analysis.
There's nothing you can surprise me about GA - in the last few years I've set up tens of GA accounts from scratch to fully working analytics platforms with +1.000.000 UU. I recommend GA to most of my clients because - when set up correctly - it's extremely powerful.
Using it both as an email marketing tool and a CRM. Automating marketing, setting up all types of automated and regular email campaigns, run A/B testing.

Bartosz was amazing. Very honest and direct in his feedback of my site which I really appreciated. He torn down my website, gave me a list of people I should talk to, worked with me through my main problem, and helped me think about both short and long term strategies. I have 2 pages of notes from our call, would highly recommend chatting with Bartosz. Thank you!
Bartosz provided me with great insights into the digital marketing course I am working on. He has a vast understanding of the growth marketing methodology and a lot of practical experience. Very friendly and open to share his thoughts. Highly recommended!
Excellent mentor, did some research ahead of time and after. Very thorough and engaging. Walked me through the early stage of Google ads account building. Will definitely be booking another session!
Bartosz helped me with much more than I was expecting. Although my initial request was about setting up my first PPC campaign, he pointed out a few important problems with my home page and provided a few valuable suggestions. Throughout the whole session, Bartosz showed genuine interest in my success. He is also a very friendly and open person, a real pleasure to chat with.
Bart provided me with some very valuable tips on creating growth strategy as well as insights on effectively mapping the user journey. He also recommended some nice tools to improve my processes. I'd definitely recommend him if you need help with anything growth-related. Thanks for your time!
Bartosz was great, he gave critical feedback to help pivot my product, and wasn't scared to hold back and ask important questions.
