Do you have an idea for a new invention? If so, our full-service roster of CAD services, 3D modelers, engineers, manufacturers, and even patent experts can turn your invention idea into a market-ready product. We have comprehensive services available for entrepreneurs and businesses looking to introduce new inventions to the world. 

If you’re working on your first invention, we can help guide you through the process. Our innovative team can help refine your idea so it’s exactly what you envision before it goes into prototyping. There's nothing worse than having to rework your invention multiple times because of issues in manufacturing. With the right guidance, you can minimize reworks and avoid overpaying.

By letting us connect you with our roster of freelancers and design companies, you're giving yourself more time to focus on your creation. We can handle the vetting and hiring while you channel your creative energy into your invention. No other service can connect you with the best designers in the world for a fraction of the cost.

Our freelance designers and design firms have worked on many types of projects including gadget design, where they regularly design cell phones and other electronics, and game design, for which they've assisted with board game creation and model design.

Our invention design services help with your project on a personalized level

Other invention help firms offer a flat rate or package deal that incorporates steps you may not need. You could end up paying more than you really need to, since what your invention requires isn’t what every other entrepreneur needs. The services you need depend on the project, its complexity, your business strategy, and how far along you are in the process.

What we offer are services that meet your specific needs. Whether you require help licensing your new product, need assistance with a patent search, or are looking for manufacturers, we can help you with that. We won’t sell you on unnecessary frills—instead, we’ll connect you with exactly what your project needs for a price that’s reasonable, whether that be rapid prototyping or electrical engineering

So you have an idea for a new invention

You’ve come up with a brilliant idea that you just need to make—maybe it’s the next million dollar idea. But how do you go about it? Here are just a few ways Cad Crowd can help.

Concept design

Concept design and development is the process of turning your idea into a functionable invention. When designing a concept, we consider factors like ergonomics, aesthetics, and price of production to ensure you get a high quality yet budget friendly product.

If you work with professional product designers, you can ensure your design is sound before going into production and wasting your precious money and time. Many entrepreneurs get stuck in the prototyping and manufacturing phases because they didn’t plan ahead by consulting with specialists, but we don’t want that for you.

Regardless of the complexity of your design, whether you're in the medical or automotive industry, our network of freelancers is experienced and ready to take your project.

CAD design and 3D modeling

This is a crucial step of the product development cycle. A 3D model can help communicate how your invention will function in real life, how the different parts will work together, and can drastically improve the time to market. CAD programs are able to test products in virtual environments to see how they would respond and interact with real world variables, allowing you address problems before they arise.

3D models and drawings help you communicate your vision to the manufacturer. These tools have made it easier for designers to get their products made, as it reduces the overhead required to start up a new project while valuing the budget.

Cad Crowd offers only the best CAD services and 3D modelers in the world. We provide quality service for less than our competitors thanks to lower overheads and a smart business model. If you’re concerned about your budget, hit us up.

Patenting and invention licensing

In addition to design and manufacturing, we can help with patenting and invention licensing. We also provide all kinds of useful information about copyright law and trademarks in the U.S. Our roster of professional patent agents and patent attorneys are ready to help you with your USPTO patent search or utility patent application.

If you'd rather let someone else worry about production and distribution, then take advantage of our invention licensing services. We'll help you get your product on the shelves of major retailers, and you'll be free to come up with your next great idea!

Prototyping and rapid prototyping

Every entrepreneur needs a good prototype to show to their investors and other team members as proof of concept. Invention prototypes can be costly, but we operate with the inventor in mind, ensuring that your budget is strictly followed without sacrificing quality.

If you’re interested in rapid prototyping, we can provide you with the resources to do that. You’ll get to pick between the different types of rapid prototyping, like concept modeling prototyping and stereolithography 3D printing. Regardless of which method you choose, we’ll make sure it turns out to be a functional prototype and will impress everyone.

If your design requires custom-made parts, you might already know that it can be expensive to do small runs. We can save you money and time by dealing with all of that for you. Pick and choose what you want, and we’ll help you get it.


If you have an invention that’s complex, having many mechanical or electric parts, you may face some road bumps during prototyping. Maybe your designer created a really good looking design, but when you made your prototype, you realized it didn’t work properly. Well, that’s where engineering services come in.

We can provide you with freelancer engineer who will analyze your design, diagnose issues before they arise saving you tons of money and time, and make sure your design works. From large scale products to small scale elecontrics, we've got you covered.

A good engineer doesn’t have to sacrifice aesthetics for functionality. Instead, they balance the two. And with our experienced team, your product will not only look good, but it will work efficiently and be very cost effective to boot.


After your prototype is complete and has been tested, you need to find the best method to manufacture it. This is a huge hurdle for start-ups and independent entrepreneurs to face as many manufacturers require steep up-front costs. If you don’t know where to look, we can help connect you with the best U.S. manufacturers and 3D printing companies. And if you don’t know what type of manufacturing best suits your invention, we can help with that too.

We have many types of manufacturing available for you to choose from. CNC machining is ideal for rapid manufacturing with little lead time, it can be used with just about every material. We also have a variety of conventinal molding and casting services available, which is best for low to mid sized product runs.
