FIRST-OF-A-KIND HARDWARE, TAKEN FROM IDEA TO MARKET.
One in-house product design and development team for industrial design, electronics, firmware and manufacturing. You bring the vision. We engineer it into a product that ships.
The worries inventors bring to the first call, and what we do about each one
“How do I know you’re not a scam?”
A track record you can check.
200+ products built, with products presented on Shark Tank and at CES 2023 and 2026.
“What if someone steals my idea?”
Protected before you say a word.
We sign an NDA first, the IP is yours, and we know how, what and when to patent.
“What if nobody wants to buy it?”
An honest answer before you spend.
We tell you on the first call, then check the market properly in feasibility.
“Do I need to manage every supplier?”
One team, from idea to shelf.
We take it from prototype to mass production, so you never chase suppliers yourself.
“What if the quote keeps growing?”
One fixed price for every stage.
Each stage is priced and agreed in writing before it starts, with no hourly billing.
“Once it’s made, how do I sell it?”
We help you launch, not just build.
We help build your brand and define the go-to-market strategy that gets it sold.
Wherever your product is today. A clear next step.

Every service a hardware product needs, from first sketch to first shipment
As a hardware product development company, one team covers the whole path, so nothing is lost between a designer, an engineer and a factory. Start at whichever stage you are at.

What a hardware product costs, stage by stage
Most development firms won't put a number on their website. We would rather you plan with real ones. These are published US industry estimates; after a free consultation, we quote a fixed price for each stage of your product.
Published industry estimates, checked November 2026. Your quote is a fixed price per stage, agreed before work starts.
Four steps, a fixed price at each one, and no surprises
Free consultation
A 30-minute call with an engineer. We sign an NDA before you share details, and you leave knowing your next step.
Feasibility and quote
We check that it can be built, certified and sold at a profit, then send a written verdict and a fixed price for each stage.
Build in stages
Design, prototype and test in rounds. Each round ends with a demo and your go or no-go before the next.
Production and launch
We prepare the factory package, run production with our partner factories and give you a free go-to-market strategy for launch.

Questions inventors ask before the first call
A hardware product development company turns an idea for a physical product into something a factory can build. Inventornest, a hardware product development company in Toledo, Ohio, handles product design and development end to end: feasibility, industrial design, electronics and PCB, firmware, prototyping, certification and the handover to manufacturing. Unlike an invention promotion firm, we sell engineering work with defined deliverables. Unlike a contract manufacturer, we design the product too.
It depends on how much custom electronics, firmware and housing your product needs. Published US estimates put a working electronic prototype at about $5,000 to $50,000 or more, industrial design at $15,000 to $30,000, and mold tooling from about $3,000 for aluminum. After a free consultation, we quote a fixed price for each stage.
A proof of concept can take a few weeks. Industrial design takes 2 to 10 weeks depending on complexity, and mold samples arrive 4 to 8 weeks after the design is signed off. Most products go through more than one prototype round (EVT, DVT and PVT), so your plan shows a date for each stage.
Your product, its IP, and the information from every stage: specifications, process and test documents, certification records, the approved parts list and production instructions. It is everything you need to brief any manufacturer or design firm, whether you build with us or not.
No need. We sign an NDA before you share anything, so talk to us first. We are engineers, not lawyers, but we help you hire the right patent attorney, at the right cost, at the right time. That is usually once feasibility shows the product is worth protecting, so you never pay to patent a design that is about to change.
Yes. On the first call, an engineer tells you honestly whether we think it can make money. If it goes to feasibility, the written verdict is one of three answers: go, change it, or don’t build it. We would rather tell you now than take your budget.
A freelancer can be the right choice for one small task. For a whole product, most freelancers build from off-the-shelf modules and hand back a prototype that works on the bench but can’t be certified or made in volume, and coordinating several of them becomes your job. We custom-engineer the product, take it through certification and production, and stay with you after launch.
Yes. We have helped launch 30+ products through crowdfunding with our go-to-market strategy. We build a prototype that is ready for your campaign video, price your reward tiers from a real bill of materials, plan certification so you can pre-sell legally, and line up production so you ship to backers on time.
Yes. Many clients start with a prototype only, and you still get the full information from every stage. If you want to go further, we take it end to end through mass production, so you never have to sort out problems between separate design and manufacturing suppliers.

No. Inventornest is an engineering firm. We sell design, engineering and manufacturing work with defined deliverables, not marketing or licensing promises. Before you sign with any firm, Read the FTC's guidance on invention promotion.
Inventornest is headquartered at 4409 Bennett Rd, Toledo, Ohio.
Many inventors start with a feasibility study or a single prototype round. Tell us your budget on the first call and we will tell you honestly what it can achieve.
