Carl TenBrink, founder of Sonos Product Development, and his team have been working to bring your invention ideas to life for over 39+ years. Sonos works with inventors, entrepreneurs, small companies as well as fortune 500 companies to develop their invention ideas into viable products that are selling around the world. We have developed products for clients, that (combined) have generated well over a billion dollars in sales all over the globe!

Sonos Product Development will provide a very personal approach to you and your invention ideas. You will work directly with Carl as you are guided step by step through the development process to maximize the potential of your invention. As each Phase is complete, you meet to review progress and are instrumental in the decision making progress to move the product closer to reality.

How much will it cost?

While there is no “base rate”, quoting a price for a prototype or project is based on the complexity of the project. Each project is as unique as each of our client ideas and therefore each project is a fairly fluid creative process, and involves an infinite number of variables, it is impossible to quote accurately through our website or by phone until we have more information from you. That’s why it’s so important to take that first step and get in touch with us!

In our many years of experience we can safely say that 80% of the time the following prices for each phase are:

Phase 1 – Concept Development – Ranges from $1,500 up to $3,950
Phase 2 – Refinement and 3D CAD Modeling – Ranges from $2,500 up to $3,950 (Complex products can be more)
Phase 3 – Prototype Fabrication– Ranges from $2,000 up to $5,000 (actual prototypes we have created have gone upwards of $5,000 due to the complexity of the product)

What is the Process?

1. If you would like to get started, complete the form at the bottom of this page and describe to us as much as you possibly can about your invention ideas. You can upload files to us if you have a concept drawing or another useful image to show the concept.
2. Once we review your idea, we provide a no obligation proposal with cost and schedule for developing your concept that will be delivered to you in 1 week or less.
3. Once you approve the proposal, sign and return to us, we will schedule project start down the road to success.

What Happens When?

Phase 1 – Concept Development – We will explore options for your idea that will expand your imagination for the functional aspects of your invention as well as conceptualizing the visual appearance to enhance your idea to best position it for commercial success and retail sales.

Phase 2 – Refinement and 3D CAD Modeling – We will make minor refinements requested in the Phase 1 review meeting and then model the product in 3D on our state of the art computer systems where the product can be viewed virtually from any angle to confirm functional and esthetic desires are addressed.

Phase 3 – Prototype Fabrication – We will build a sample of your invention for proof of concept, photography and sales materials. You will be able to hold, testing and show your product to the world.
* Please Note; Generally, phases 1 and/or 2 must be completed before we can start to develop a prototype.

Phase 4 – Branding/Marketing – We can assist with your logo and company identity design and setting up an e-commerce based web site with optimized SEO and credit card processing along with other attractive web features. Your production can be set up as a turn-key/hands off solution positioning you for success! We also offer a service for storage and drop shipping of your orders.
