Meet the founder
Meet Jarek Siekierski, founder
Jarek has spent 16 years in SEO. He started in Warsaw, moved through agency work in Australia, and built DatGrowth to do the work the way he thinks it should be done: senior, direct and measured.
I genuinely dislike nonsense. I prefer to keep things straightforward, without complicated contracts and endless cancellation policies.
Jarek Siekierski
Today he focuses on three things:

DatGrowth
Founded in 2021. Working with clients in the US and Europe.
Education
- BA in English Philology, University of Warsaw.
- BA in International Trade, Poznań University of Economics and Business.
English is his working language: most of DatGrowth’s work is for English-speaking markets.
Why precious metals
One niche on our list isn’t an accident. Jarek has followed gold and silver markets for years as a personal interest, which is why bullion dealers are one of the industries we know from the inside.
Why founder-led
Most agencies sell you the founder and hand you to a junior. We don’t.
Jarek runs your strategy.
He sets the plan, reviews the data and signs off every report.
You talk to the person who decides.
No account manager relaying messages.
Specialists handle execution.
Content, outreach and technical work. Jarek checks it before it reaches you.
A client once put it better than we could:
While he is the front man with the knowledge, he affects much greater results through the competent team of supporting professionals he has curated.

How we work
How we work
01
We say “no” when something won’t help you
If a tactic doesn’t benefit your business, we tell you, even when it’s something you asked for. That includes the fashionable ones. For example, we’ll set up llms.txt and schema because they’re cheap hygiene, but we won’t sell them to you as the thing that gets you cited. The evidence says they aren’t.
02
We measure, and we show you the numbers
Every engagement starts with a baseline: your organic traffic, your rankings and your share of AI answers. Every report compares against it. You see the same data we see.
03
We don’t promise what nobody controls
Nobody can guarantee that ChatGPT will recommend you. We guarantee delivery and reporting: the agreed work, done on time, with an honest monthly report on what moved and what didn’t.
04
We think about your whole business, not just SEO
SEO serves a business goal, so we start from the goal. Several clients have told us some of our most useful advice had nothing to do with rankings.
Jarek was very keen to give us new ideas and suggestions for our entire marketing strategy, not just for SEO.

Who we work with
Who we work with
We work with established businesses that want to be the name AI recommends in their category. Most of them sell in markets where trust decides the sale.
Finance & fintech.
Payment platforms, advisory firms, financial comparison sites.
Precious metals.
Bullion dealers and investment metals.

YMYL content, where E-E-A-T is not optional.

Working with DatGrowth also allowed us to work better in improving our E-A-T (Expertise, Authoritativeness, Trustworthiness) and YMYL (Your Money Your Life), which is vital in the medical/pharmaceutical industry.
