Custom Product Development: Get a Custom Prototype Made

From your design to a tested prototype or sample, with the costing, production plan and suppliers set before mass production.

Start Your ProjectSee the process
Prototype measured by one of the leading product development companies
Two routes

A new prototype or an adapted custom sample.

Costing

Your price per piece before production.

In-house

Assembly and related work.

Small first

Orders accepted while you grow.

All-in-one custom product development

Custom product development takes four steps between an approved design and mass production.

Next: manufacture your product
  1. 01

    Build a prototype or sample

    New products get a prototype; others are best served by adapting a similar existing sample. We test function and use in detail.

  2. 02

    Establish the cost

    Product costing shows how the product can be made economically and where cost can come out.

  3. 03

    Make a production plan

    We review the supply chain and scaling bottlenecks so you have contingency plans before you grow.

  4. 04

    Select components and suppliers

    We test suppliers on price and quality for each part. Assembly is done in-house.

Custom prototype samples compared side by side

Prototype or custom sample?

In custom product development we check what already exists before building from scratch.

  • Prototype

    For truly new products made from scratch, also called OEM manufacturing.

  • Custom sample

    For products that already exist in a similar form: a new shape, function or brand. Usually faster and cheaper.

  • Costing first

    A beautiful prototype is useless if it cannot go into a production line affordably.

Custom product development questions

What clients ask before building a prototype.

When do I need a prototype?

When the product is truly new and nothing similar is made today. We check what already exists first, so you only pay for a prototype when you need one.

When is a custom sample the better route?

When a similar product already exists and you want a new shape, function or brand. This is private label, white label or ODM, and it is usually cheaper and faster.

Are product costing and a production plan really necessary?

Yes. Custom product development matters because a great product is half the battle. Knowing the cost structure and how production scales is the other half.

What do development and minimum quantities cost?

Prototypes cost more than custom samples, and the price depends on the category. Our main suppliers usually accept small first orders because we bundle many projects.

How do you protect my design?

We always sign an NDA before you share your design. It is a standard step in our workflow.
