Newsletter Growth Hub
Every week, one concrete insight that changes the way you build growth.
Mateusz Baranowski. Once a week, one framework, figure, or tactic from real B2B and e-commerce projects. No theory, under 5 minutes of reading.
What do you get in the box
Not inspirations. A concrete action you can implement this week.
✓Weekly framework with case study
One proven action plan, shown on a real example, not on a slide.
✓Data from the Polish market, not opinions
Numbers, benchmarks, and insights from the campaigns we run. Data > opinions.
✓Tactics tested on customers
What we actually test in Growth Hub on B2B and e-commerce before it reaches you.
✓Once a week, under 5 minutes
No spamming the inbox. One email you can read over coffee.
What am I writing about
Topics that return in the newsletter because they genuinely drive growth.
- Demand generation, not buying leads
- CAC, LTV, and the Actual Cost of Acquisition
- AI in marketing, practical applications
- CRO, conversion optimization
- Growth experiments, how to test
- Google and Meta Ads for sales, not clicks
Mateusz Baranowski
I run Growth Hub, a B2B and e-commerce growth marketing agency. I test frameworks on real clients and co-host the Growthfellas podcast. The newsletter is my lab notes: what works, what doesn't, and why.
