Hi, I'm Radosław Mentel
Smart business owners don't scale revenue - they scale profit. Step by step.
No more mindlessly pumping budgets for a pretty ROAS. I run Google Ads campaigns that safely grow your business's real profitability.
- Over 17 years of experience
- You work directly with me (not a junior)
- No notice-period contract
- Focused on margin and net profit
- I work with a limited number of clients
- Teaching marketing at SGH (Warsaw School of Economics) for 7 years
Does any of this sound familiar?
Reports full of virtual wins
The agency celebrates a record ROAS and thousands of clicks, but at the end of the month your business account is still empty.
The "salesperson and junior" effect
An experienced expert sells you the service, but your money is managed by an intern learning optimization on your budget.
A contract with no way out
Campaigns are burning through your budget, but you can't leave - a 12-month contract keeps you locked into paying for losses.
Analytics chaos and guesswork
You hear that "the ads are building awareness" because the agency can't connect Google Ads to real profit at the cart level.
Time to break this pattern.
Instead of handing your budget to an agency, you switch to direct collaboration with an experienced expert - no middlemen, no rigid contracts, focused on real results.
I'll be upfront about it: playing for the same goal takes commitment from both sides.
Why work with me?
You pay for a senior, you get a senior.
You're buying my expertise, not agency overhead. You don't pay sales commissions or salaries for people forwarding emails. Your entire service budget goes into real work.
Zero trap contracts, no fine print
You stay for the results, not because a contract clause forces you to. I don't lock you into 12-month terms. We work together for as long as you see results - you can end the collaboration in any given month.
Full ownership of your data
Your accounts, your results, your data. Even if our collaboration ever ends, I don't take the setup or customer data with me.
A strict cap on projects
Full attention instead of mass-market volume. I don't take on every project that comes along. I work with a small group of companies, which lets me dig deep into their margins and treat them like my own business.
How can I help you?
Let's leave templates to the competition.
Every business has different margins, different goals, and different challenges. Instead of selling rigid packages that fit everyone and no one, I build Google Ads campaigns around exactly how your business actually makes money.
01
Google Ads management and optimization
For e-commerce and B2B companies that want to scale profit, not just spend.
I build and run campaigns (Search, Performance Max, YouTube, Demand Gen, Display, App) focused directly on the products and services that generate the highest margin. I cut out budget wasted on empty clicks and traffic that never turns into money in your pocket.
02
Google Ads & Analytics audit (GA4 / GTM / BigQuery)
An independent check on what's really happening in your account.
Miscounted conversions, duplicated events, or a poorly implemented Consent Mode v2 can completely break your ad algorithms. I examine the technical implementation of GTM tags, GA4 configuration, and how your accounts connect to Google Ads, Merchant Center, YouTube, and Search Console. I clean up the mess in the code, so you can make business decisions based on hard facts.
Scope, sample finding and audit pricing →03
Conversion rate optimization (CRO) consulting
Turning existing traffic into real orders.
Paid traffic from ads is only half the battle. If your purchase path loses customers at every step, no ROAS number will save the outcome. I analyze user behavior and deliver concrete recommendations that turn abandoned carts into real profit.
04
Custom AI & automation support
Using the technology while keeping a human fully in control.
I put AI to work on what it does best: analyzing huge datasets, spotting budget anomalies fast, and finding non-obvious areas to optimize. I treat AI as an incredibly fast assistant, not the one holding the wheel. Every recommendation the algorithm makes passes through the filter of my 17+ years of experience before it's allowed to spend a single cent of your budget.
Who do I build analytics and campaigns with?
Over 17 years, I've helped dozens of brands - from local e-commerce stores to giants in the automotive and finance industries. Here are a few of them:
- HPE
- Orsay
- Orange
- Nissan
- Credit Agricole
- Suzuki
- Saeco
- Intermotors
- Arval
- Glany Steel
- Artlife
- FreecoNet
- Wedel
- Moose
- Meroway
- Esprado
- Felgeo
- Nashuatec
You won't see the biggest players here.
The most advanced projects and the largest budgets require discretion.
An NDA is standard practice, not an excuse.
What clients and colleagues say
Real recommendations from LinkedIn.
I worked with Radek in one team on several projects. Radek was the person who had the greatest knowledge in such areas as Web Analytics, SEM, and SEO. Customers have always been impressed by how Radek can use their business potential. His excellent results always impressed everyone in the team, he did impossible things! I also remember Radek as a very communicative person who loves what he does.
