The complete guide

Understanding the GrowthFit interview series

The GrowthFit interview series features top D2C marketers, founders, and CRO experts sharing what actually moved the needle for them. The conversations are short, tactical, and free to watch on demand.

Each episode distills hard-won lessons — the experiments that worked, the ones that didn’t, and the operating principles behind a high-velocity growth program — into takeaways you can apply to your own store.

It’s the kind of practitioner insight you usually only get over coffee with a veteran operator, collected in one place for the CustomFit community.

Who is it for?

Marketers, CRO teams, and founders who want to learn how experienced operators run experimentation and growth.

Is it free?

Yes, every interview is free to watch on demand.

Who do you interview?

Top D2C marketers, founders, and CRO experts — practitioners, not pundits.

Where can I watch?

Right here in the interview series, on-demand and free.

Can I be a guest?

We’re always looking for sharp operators — reach out via Contact.

Do I need a developer to use CustomFit.ai?

No. Marketers build experiments and personalized experiences in a no-code visual editor; developers can use the API and SDKs when they want deeper control.

How quickly can I get started?

Most teams install in minutes via a single script tag or the Shopify app and ship their first experiment the same week.

Want to be on GrowthFit?

We feature D2C operators and CRO experts with a story worth sharing.
