More value per member
Keeping members longer and growing what each one is worth: fewer cancellations, more recurring revenue per member or client.

- Email & automations
- Win-back campaigns
- Revenue per member
From the field
Every fitness business I have audited was leaving meaningful revenue on the table, sometimes up to €30,000 per month. The fix rarely sits in a rebrand; it sits in the conversion economics underneath.

Build a brand that still exists, and still grows, ten years from now.
You don't build a distinctive brand by shouting the same line as everyone else. Since 2017 I have been doing this with one niche, fitness and health, and one approach, evidence-based.

Who you'd work with
Hi, I'm Vince.
I run Vince Online Marketing myself. Since 2017 I have worked with science-led fitness and health brands, from gyms and coaches to apps and clinics. When you hire me, you work with me, not a rotating account team.
How we work together
Three steps, no lock-in.
A first call
45 minutes. I go through where your marketing is stuck and whether I am the right person to help. No pitch, no obligation.
Diagnosis and plan
I look at your funnel, data and positioning, and come back with the few changes that actually move the numbers, in priority order.
Build and instrument
I fix the conversion economics and instrument the funnel, so every next decision is grounded in something real. You can stop whenever you want.
