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.
- 01
Before you back
Read the story and the milestones. Check that the amounts add up and that each step has something concrete to prove. If anything is unclear, ask in chat first.
- 02
While the dream runs
Your backing is split across the milestones. When proof is posted you are notified and can release your share or ask for more. You can back anonymously.
- 03
If something goes wrong
If you do not release a milestone in time, the money still held for it and later steps comes back to you, minus the fee. You can report a dream or block a user at any time.
Example milestone plan
An example plan for a robotics project dream with a goal of €13,000. Backers fund the whole goal, but each milestone's money stays held until you post the proof and Backers release it.
Milestone 1
€2,600 · 20%
Define the robot task
Post a task diagram, workspace measurements and a bench test showing the proposed sensing or movement principle.
Milestone 2
€4,550 · 35%
Assemble the robot platform
Share chassis build photos, actuator and sensor receipts, and wiring diagrams with a record of mechanical fit checks.
Milestone 3
€3,900 · 30%
Integrate control software
Upload a controlled demonstration, control code summary and logs showing sensors and movement working through the planned task.
Milestone 4
€1,950 · 15%
Repeat controlled trials
Post repeated trial logs, a fault summary and a video showing the test area, stop controls and final task sequence.
Risks to plan for
- R1
Mechanical loads exceed estimates
A motor may struggle once the complete assembly carries its intended load. Check loads during platform assembly and reserve components budget for gearing or actuator changes.
- R2
Sensors misread the workspace
Lighting, surfaces or obstacles can upset sensing outside a bench setup. Include varied controlled trials in integration and allow time to adjust placement and filtering.
- R3
Integration consumes trial time
Individually working parts can fail when combined on the robot. Set a limited task for the control milestone and protect a separate final budget for repeated trials and spares.
Questions and answers
Can I see how my money was used?
Yes. Each milestone shows the Dreamer's proof, how much is held and how much is released. You only release money for milestones you have reviewed yourself.
Do I need a fully autonomous robot to show meaningful progress?
Demonstrate the specific task and state which actions are manual, scripted or sensor-driven. A bounded controlled test gives Backers clearer evidence than an autonomy claim without repeatable trial records.
How can I document robot tests responsibly?
Show a controlled test area, the stop method and the limits of the demonstration. Share trial logs alongside video so Backers can distinguish a repeatable sequence from a single successful take or edited highlight.
