For D2C founders who are tired of guessing

Hi, I’m Polin. I help good brands sell more and keep more.

After 60+ brands, I’ve learned most D2C brands don’t need more traffic. They need to fix where shoppers give up and what each order really costs. Send me your store and I’ll show you both in a free 2-minute video.

Recorded by me, for your brand. No call. No pitch. If you never speak to me again, you keep the video.

Let’s find your first fix.

Four quick taps, about 30 seconds. I’ll build your video around your answers, not a template.
