Fund a mobile app dream in Paris without equity

Many people think the only way to raise money is to sell part of what they build or to borrow. On cohero, backings are gifts. You keep full ownership of your mobile app dream and everything it becomes.

A mobile app budget must connect screen designs to working features, device testing and a maintainable release. Show usable builds at each stage rather than treating downloads as proof.

  1. 01

    Gifts, not investments

    A backing is a voluntary gift towards a goal. Nothing is sold, no ownership changes hands and no return is promised. Backers support a person; you keep control.

  2. 02

    Why milestones still matter

    Without contracts, Backers rely on transparency. Money is held per milestone and released only when you prove progress, so they can give with confidence.

  3. 03

    What you owe Backers

    Honesty: a true story, proof for each milestone and updates in chat. Not profits or repayment. If you cannot finish, unreleased money goes back to Backers.

How Backers are protected

14-day review per milestone

When proof is posted, each Backer has 14 days to release their share or ask for more. Money not released in time goes back to the Backer.

15% fee, deducted — never added

Backers pay exactly what they choose. The 15% fee comes out of each backing: €100 gives the Dreamer €85. The fee is kept if money is returned.

Gifts, not shares

Backings are gifts. No shares, equity, interest or repayment, and Dreamers keep full ownership. Nothing on cohero is an investment or a loan.

Example milestone plan

An example plan for a mobile app dream with a goal of €27,000. Backers fund the whole goal, but each milestone's money stays held until you post the proof and Backers release it.

  1. Milestone 1

    €4,050 · 15%

    Build the main features

    Share a recorded walkthrough of a working app build, completed feature checks and a summary of remaining development tasks.

  3. Milestone 3

    €6,750 · 25%

    Test across devices

    Upload a device test matrix, anonymised crash reports and before-and-after evidence for the main issues resolved.

Risks to plan for

  • R1

    Feature scope keeps growing

    Extra features can absorb development time before the core flow works. Lock the first build scope in the prototype milestone and keep optional ideas outside its budget.

  • R2

    Device-specific failures

    A build that works on one phone may fail on another screen or operating system. Budget for a defined device test matrix and reserve time for fixes before release preparation.

  • R3

    External service changes

    An app may depend on services with changing limits or interfaces. Identify those dependencies early and include integration checks and a fallback plan in the release work.

Questions and answers

Can I share app progress without exposing user data?

Record a demonstration using invented accounts and sample content. Remove credentials from logs and screenshots, and use anonymised issue summaries so Backers can review the build without seeing real user records.

Do I have to pay Backers back?

No. Money released for completed milestones is yours. Money still held for unfinished milestones can go back to Backers under the Backing Policy, minus the platform fee.

Do I need a finished app before creating a funding dream?

You can start with a clearly scoped prototype and development plan. Show which screens are interactive, which features still need code and how later milestones will provide working builds and device test evidence.
