The Reality of Scaling

You've already done the difficult part.

You launched. Now the real complexity begins. Scaling a supplement brand is not just about increasing ad spend.

  • Claims risk that compounds as you grow
  • Agencies that can't explain performance volatility
  • Rising CACs with weak retention systems beneath them
  • Not knowing whether a better ingredient or format just hit the market
  • Manufacturers that are "fine" - but not world-class

The founders who scale well aren't necessarily better founders. They simply get access to better information earlier. That's what The Formula+ was built for.

Not a course. Not generic networking.

A live, operator-led environment where experienced founders get direct access to specialists actively scaling brands right now.

High-signal. No fluff.

Every session focuses on practical execution - from what’s working on Meta to trending ingredients and costly compliance mistakes.

Better operational relationships.

Direct access to vetted manufacturers, ingredient suppliers, and packaging partners that have taken hundreds of deals to build.

"Scale faster, avoid costly mistakes and get insider access to the latest trends before they hit the market."

What your month looks like

Live growth and scaling sessions. Every month.

Inside the community, you get practical implementation across Meta, TikTok, Google, Klaviyo, compliance, sourcing, and trend intelligence - all built for serious supplement founders.

retention systems, and offer positioning - live.

ZoomwithCat

Every Session Is a Shortcut.
