Preparing a €250K Pre-Seed Round

The monetisation platform built for fitness creators.

Creators already have the audience. OnlyMass gives them the infrastructure to turn it into a business.

The Problem

Fitness creators built audiences. They didn't build infrastructure.

A creator's business today is spread across five disconnected tools. Nothing is joined up — not the content, not the payments, not the community, not the results.

Social media

Audience lives here

Programmes

PDFs & spreadsheets

Payments

Ad-hoc links

Community

Group chats

Coaching

DMs & email

The result: revenue leaks, no retention, no data, and a business that stops the moment the creator stops posting.

The Solution

One platform. Built around the fitness creator business.

OnlyMass replaces the stack with a single operating system for the fitness creator — content, monetisation, community and progress in one place.

Two-Sided Value

Creators get a business. Users get a result.

  • Challenges that keep training social
  • Progress tracking and gamification

Business Model

We succeed when creators earn.

OnlyMass takes a share of what creators make. The more a creator contributes to the network, the smaller that share becomes — permanently.

Tips

Invite & Earn

Creators can earn a permanently lower platform fee by helping grow the network.

When an invited creator qualifies by connecting Stripe and publishing the required creator content, the referring creator's platform commission drops by 5 percentage points permanently.

Referral rewards are applied to the creator's effective commission rate and do not expire.

Discretionary

Founder/Admin-approved creator rates may go as low as 5%.

5% is not the standard rate. It applies only on individual Founder/Admin approval.

Creator acquisition becomes part of the product itself: creators are financially rewarded for bringing other qualified creators onto OnlyMass.

Current Stage

Pre-launch. Product built. Distribution next.

OnlyMass is currently in closed beta ahead of its mobile launch. Existing accounts are limited to founder-controlled accounts and a small group of invited beta testers used to validate product flows and functionality.

This isn't a pitch for an idea — the platform is built and operational today.

Public creator acquisition has not started yet. The €250K pre-seed round is intended primarily to move OnlyMass from product validation into distribution and market validation.

Why Now

The window is open. It won't stay open forever.

Fitness creators are growing. Online coaching is becoming normal. AI is making software dramatically easier to build. And consumers are overwhelmed by fragmented fitness content. OnlyMass has the opportunity to establish the marketplace before the category becomes crowded.

01

Fitness creators are becoming businesses

$480B

Projected global creator economy by 2027

Creators are increasingly looking beyond sponsorships and social algorithms for direct, recurring income. OnlyMass gives fitness creators the infrastructure to monetise their audience directly.

02

Fitness has already moved online

345M+

Fitness-app users globally

Online coaching, mobile programmes and creator-led fitness are no longer temporary behaviours. The audience already exists. The behaviour already exists.

03

AI is collapsing the barrier to building software

Building gets easier. Distribution gets harder.

AI means more founders can launch more products, faster and cheaper than ever. The long-term advantage is increasingly not who can build the app, but who owns the creator relationships, community, brand and distribution first.

This is why delaying OnlyMass carries real strategic risk.

04

Consumers have too much fitness information, not too little

There is endless fitness content — but it is fragmented.

More information is not the answer. Better structure is.

OnlyMass brings creators, programmes, challenges, communities and monetisation into one dedicated fitness ecosystem.

Most platforms make money from their users. OnlyMass is designed to make money with them.

Free to join

Users can access the platform and participate without being forced through a platform-wide paywall.

Creators decide what they monetise

Free content can coexist with subscriptions, premium programmes, tips and paid experiences.

Creator-aligned economics

OnlyMass earns when creators earn — with platform commissions that can decrease as creators contribute to growth.

The market is validated. The category is still open.

Existing fitness monetisation platforms prove that consumers will pay fitness creators. OnlyMass is competing to build a broader fitness marketplace and community where joining the ecosystem is free and creator monetisation is embedded throughout the product rather than being the entry ticket.

Technology can be replicated.

A creator network, brand, community and distribution engine are much harder to replicate.

That is why we are moving now.

Build the network before the market gets crowded.

Go-To-Market

Product risk reduced. Distribution is the next problem to solve.

The Raise

Preparing a €250K Pre-Seed Round

To take OnlyMass from a built product to a validated and repeatable distribution engine.

Use of funds

25% Product. 75% Go-to-Market.

40% of the round is dedicated to creator-led distribution and UGC.

OnlyMass is a creator platform, so our primary distribution thesis is creator-led: partnerships, short-form UGC, creator seeding, paid amplification of winning content and systematic testing of the channels that convert.

How the Month-12 target adds up

At a 10% average effective OnlyMass fee, €10K in monthly platform revenue corresponds to approximately €100K in monthly creator GMV. At the target mix, roughly 700 monetising creators would need to generate about €143 per month each.
