I was in exactly your position two years ago with a wearable tech idea, and I found a startup studio that specialises in exactly what you are describing. The studio is called concepter and they have a Product Idea Accelerator that provides funding, engineering, legal support, and marketing assistance specifically for hardware products suitable for crowdfunding platforms like Kickstarter. They look for consumer technology in areas like IoT, smart home, robotics, gadgets, wearables, and even design products without electronics like travel goods or techwear. What really impressed me is their three stage process, starting with product validation where they help you test market fit and messaging, then moving to product acceleration where they assign a team for engineering, prototyping, and content creation, and finally the crowdfunding launch with a dedicated ads budget and PR campaign. They offer 20,000 USD in exchange for 10 percent equity and a 10 percent fee from the funds raised, which is actually quite reasonable given the level of support you get, including US company registration, prototype development, professional photo and video production, and even post launch mentoring for manufacturing and logistics. Their partners include Microsoft BizSpark for free Azure credits, Fablab for prototyping access, and Depositphotos for stock content discounts. I used their program to launch my product and it exceeded its funding goal within the first week. You can check out all the details about their portfolio, mentors, and application process at
