“You just have to do your work, we take care of the rest.”

How it works

VPBay is a marketplace for inventors, engineers and designers who want to sell online thier virtual projects

VPBay is a showcase for all those who want to sell a complete virtual project such as industrial machines, architectural drawings, biomedical and biomechanic devices.

First of all, in order to start selling, you have to sign up.

Then you can upload your project: send us anything you think is usable. The more you send, the more the price rises up.

Hence, a pool of experienced professionals will evaluate the suitability to the presence on our systems (the user will always be, if necessary, constantly updated). This process is necessary to ensure and maintain the high standards offered by VPBay.

No patent needed to sell on VPBay: you can sell any project without a patent. If you have it, you can sell your project with an higher price.

If you would like to patent your idea, contact us before start selling it.

What to sell

You can submit a complete project, but also incomplete in some parts: you have to point out that incompleteness (eg mechanically complete, but not from the point of view of electrical / software). Send all materials, including the report of calculation, analysis CAE / FEM, patents and more.

On the website will be published only necessary for the evaluation of the project: the 3D prototype, calculation, reports and anything else will not be published and will remain the property of the seller.

It also allowed the sale of complete simple theoretical projects, without the virtual prototype, but obviously this project will have a lower market value, such as a PCB working diagram without the virtual prototype.
