I have been working with Ben for around a year and would definitely recommend him. I made a few changes through the process and he always took the changes in stride while advising me on whether or not those changes were feasible for manufacturing. He is always very responsive to emails and calls. If you can, talk to him before you submit a patent. I wish I had done that and saved myself some headache.

Working with Inventions Unlimited has been nothing short of life changing. From day one, the entire team has gone above and beyond to bring our idea to life, not just as professionals but as genuine partners who care deeply about what they do. Ben, David, and Alex have been incredible to collaborate with: patient, insightful, and truly invested in every detail of our prototype. Campbell has been an absolute gem to communicate with - her warmth and responsiveness made every step smooth and encouraging. You can really feel how passionate everyone here is about helping inventors turn dreams into reality. Every visit to their office feels inspiring (and we can’t forget Zelle, the cutest office dog who always brightens the day). It’s rare to find a team like this. If you’re looking for people who will treat your invention with the same care and excitement you have for it, look no further. Thank you, Inventions Unlimited, for making something that once felt impossible, possible.

I am happy for this opportunity to share my experience with Inventions Unlimited. I came to them with not much more than a good idea and a desire to get it to market somehow. From the very beginning they were a pleasure to work with, exceptionally knowledgeable, patient and supportive. They successfully completed my prototype and I am thrilled with it. I learned so much about the process while working with them and also about an action plan to get it to market. Inventions Unlimited doesn't stop with the prototype. After they have been paid they stay with you as mentors to ensure the success of your product with introductions to trusted manufacturers and potential investors as well as other connections. It's a comprehensive approach. Choosing Inventions Unlimited is the best decision I ever made.

I can’t put into words how highly I recommend Ben and his team. I did a bit of research and had meetings with two other Invention companies before deciding on Inventions Unlimited. Once I got off the call and received the initial write-up it was crystal clear I’d be moving forward with Ben. The amount of research that was done for my product and the industry really blew my mind. Additionally, I’m not exaggerating when I say that the quote I received was literally 1/5 the cost of another well-known, large-scale manufacturer that I talked to. Ben runs a business that is small enough to be personable, and you can tell they truly care about their clients. I could not be happier with the direction that things are going. Thank you, Ben, Campbell, and everyone at Inventions Unlimited for helping make this product a reality! For reference, my product is the ArachnoFriend catch cup system. Which helps keep the tarantula hobbyist and the tarantula safe during rehousing and routine maintenance.

I had the fortunate opportunity to enlist IU as my company to develop a prototype for a patent pending product. Compared to other companies that offered less but cost more, made my selection process easy. They were knowledgeable, creative and responsive every step of the way. If you're searching for an engineering firm to handle your product development. Take it from me, don't look any further than Inventions Unlimited.

It is my pleasure to enthusiastically recommend Ben Greenberg and his company Inventions Unlimited for developing product designs and prototypes; particularly, 3D printed prototypes.  Ben has proven to be highly skilled at developing products and taking my clients invention from the idea and development stage to the final creation of a viable, working, and manufacturable prototype. Ben is a problem solver and a highly creative designer. Ben’s attention to detail and persistence to perfect the designs needed for my clients has continually impressed me. His knowledge in CNC manufacturing, thermoforming, injection molding and other industrial manufacturing technologies has been highly valuable to my clients.  Ben and I have worked together on many projects over the years, including a fishing lure from Chatterlures, which has revolutionized the deep-sea fishing industry.

In addition to the fishing lure noted above, Ben has developed product ideas for the following industries: pets, food preparation, automotive, hair, construction, sports, as well as many others. In conclusion, I am happy to recommend Ben Greenberg to any other patent attorneys, or anyone seeking to take a product concept through design, prototype development, and ultimately larger scale manufacturing.

I am equally glad to have this outlet for my clients. Unlike other prototype companies I have worked with, I believe that the prices that Inventions Unlimited charges are extremely fair, your work is timely, and you guys are honest.  This is actually a rare combination.

Ben and Brad Greenberg were an absolute pleasure to work with from our initial phone call through the completion of our invention. Ben helped us find a manufacturer who could bring our product to life, and both Ben and Brad were professional, knowledgeable, and supportive throughout the entire process. We truly appreciate their hard work and dedication and highly recommend Inventions Unlimited to anyone looking to develop an invention.

I was introduced to Inventions Unlimited by my patent attorney. Right from our introductory conference call, Ben and Brad Greenberg made me feel completely comfortable and confident about moving forward. Their estimated costs for bringing my prototype to a marketable product were fair and reasonable. When Ben presented the final design for my product, the “SafeSupply-FreezeGuard,” I couldn’t have been more excited or proud. The design process was originally scheduled to take 60 days, but because of the seasonality of my product, they gave me the option to expedite the timeline to 30 days. Ben truly went above and beyond, working nights and weekends to hit this deadline—and I have the emails to prove his incredible work ethic! Throughout those 30 days, Ben and Brad stayed in constant communication. We had at least five conference calls, alongside numerous phone calls and updates. Remarkably, they beat the accelerated deadline and delivered everything three days early. They are now producing my first batch of inventory to help launch my new company. I cannot thank Inventions Unlimited enough for helping me bring my dreams to life!

It is my pleasure to recommend Ben Greenberg for prototyping and design work. I worked with Ben on a product used in the fishing industry and was extremely impressed with his knowledge and work ethic. Ben was easy to contact, easy to understand and ready to listen to and accept my thoughts and critiques. He was, best of all from my viewpoint, very professional and knowledgeable on a variety of manufacturing subjects and was able to advise me on the best method to move forward with mass manufacturing for my invention. Ben provided thoughtful suggestions regarding material properties. I believe that Ben Greenberg and his team at Inventions Unlimited would be an excellent choice for prototyping and design for any invention idea or concept
