Difference

Questions to ask before you choose

Use the same buyer questions with every provider, The Fittest Agency and 4Select included. Where The Fittest Agency publishes nothing on a point, we say it is not published and do not read that as absence.

  1. 01

    Who runs the work?

    4Select is specialist-run: a named growth consultant implements and optimises strategy, marketing, sales and retention with you. How The Fittest Agency staffs and runs delivery is not published on its site, so ask for it in writing.

  2. 02

    Is retention covered?

    At 4Select, retention work (attendance, engagement and churn analysis, club action and lifetime-value tracking) requires 4Select Club and runs in Dialanta. 4Select Grow covers marketing and sales only. See retention. The Fittest Agency's retention scope: see its official source below.

  3. 03

    Software you run yourself, or a specialist who runs it?

    Dialanta works independently if you want to operate the software with your own team. 4Select adds specialist implementation and ongoing optimisation on top. Pick the model that matches the time and skill your team has.

  4. 04

    What does it cost?

    4Select: Foundation €5,999 one-off, then 4Select Grow €999 or 4Select Club €1,199 per month, excluding ad budget and cancellable monthly. See pricing. The Fittest Agency's prices are not published on its site; ask for a written scope and price.

  5. 05

    Which pillars do you need?

    Check each against the four pillars: strategy, marketing, sales and retention. The right choice is the one that covers the gaps in your club today.

Choose The Fittest Agency if...

  • You are a personal trainer or small studio owner who wants Dutch-language support on advertising, automation or search.
  • You prefer to buy one solution area at a time and keep your existing tools.
  • You value a short, personal line of contact with a small agency focused on fitness.
  • You want to compare scope and price in writing first: The Fittest Agency's pricing is not published on its site.

Choose 4Select if...

  • You want a specialist team to implement and keep optimising strategy, marketing and sales for your fitness or health club.
  • You want retention work as well. It requires the 4Select Club partnership (€1,199 per month).
  • You want a cancellable monthly partnership after the €5,999 Foundation. Trade-offs: the Foundation is paid up front, ad budget is extra, and 4Select works only with fitness and health clubs.

Different models suit different clubs. Compare what each option covers against what your club needs, and ask every provider the same questions.
