For gym, sport and lifestyle creators

You fight for the audience. We work the corner.

We build and run a product your followers actually want, behind the scenes. You keep creating. Nothing upfront.

You already have the hardest part: people who listen to you. What's missing is something of your own to sell. That's the part we build.

Two jobs. You keep the one you're good at.

In the ring: you

  • Make content, like you already do
  • Tell your audience about the launch, in your own words
  • Approve everything before it goes out under your name

In the corner: us

  • Find out what your audience would pay for
  • Build the product, the sales page and the checkout
  • Write the launch plan and the scripts
  • Handle customer questions, updates and the backend

From first call to first sale

You see a concrete plan before you commit to anything.

  1. Read the room

    We go through your content and comments to find what your followers keep asking for.

  2. Show you the plan

    A product idea, a price and a launch plan, on paper. You decide if we go ahead.

  3. Build it

    We make the product, the sales page and the checkout. You review and approve.

  4. Launch

    You announce it to your audience. We run everything behind it.

  5. Keep it running

    After launch we keep improving the product and the page, so it keeps selling.

The deal, in plain words

Nothing upfront

No setup fee, no monthly retainer. We earn when the product sells.

A share, agreed in writing

We agree on the split before any work starts, and put it in a contract.

Your name stays yours

Nothing goes out under your name without your OK.

Open about AI

AI agents do much of the research and building. A person handles every conversation with you.

Questions creators ask

What does it cost me?

Nothing upfront. We take an agreed share of what the product earns. If it doesn't sell, we don't earn either.

Do I have to film more?

Only as much as you want. The launch posts are yours to make. We write scripts if you'd like them.

Who is a good fit?

Gym, sport and lifestyle creators with roughly 10k to 100k followers, an audience that comments and asks questions, and no product of their own yet.

Do you use AI?

Yes, for research, drafts and building. Every decision about your product goes through a person. If you ever talk to an AI agent, we tell you.

Who is behind Cornerman Studio?

Cornerman Studio is part of VonkAI, a small Dutch company that builds online products.

Got the audience? We'll build the rest.

Send us your handle, your platform and what you make content about. We read every application ourselves.
