What you receive
- Backers give
- €13,000
- 0% platform commission
- −€1,950

- 01
Price from quotes, not hopes
Get at least two quotes for every large cost and note what is included. Backers rarely mind a high goal; they mind a goal that looks invented.
- 02
Plan for what you receive
cohero takes 0% commission on backings, so you receive what Backers send directly through your payment methods. Set the goal so that amount covers your real costs.
- 03
Add a small buffer
Prices move. A buffer of five to ten percent in your last milestone covers surprises without making the goal look padded. Say so openly in your story.
Example milestone plan
An example plan for a robotics project dream with a goal of €13,000. Backers pay you directly, funding the goal all at once or milestone by milestone as you post proof for each step.
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.
How Backers are protected
14-day review per milestone
When proof is posted, each Backer has 14 days to review the proof, ask for more info, and decide whether to keep supporting your next milestone.
0% commission — direct gifts, nothing taken
Backers pay exactly what they choose directly through your payment methods. cohero takes 0% commission on backings, so you keep what is sent. Any refunds or disputes are handled directly between you, the Backer and your payment provider.
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.
Questions and answers
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.
Does cohero take a commission on backings?
No. cohero charges 0% commission on backings. Backers pay you directly to your chosen payment method, so towards your goal of €13,000, you receive the full amount confirmed by you without platform deductions.
