By Reid Abrams, Mechanical Engineer
The right product development firm for a first-time inventor has engineers on staff, bills by the hour or by deliverable, transfers 100% of the IP in writing, and can show you manufactured products rather than renderings. Most companies that appear in a search for "product development company" are one of four types, and the type predicts your outcome more reliably than the brand does. This page puts eight of the most-found companies side by side, RMA Engineering included, using only facts each firm publishes about itself.
A note on method, because comparison pages are usually written to sell. Every fact below comes from the firm's own website or its public Clutch, DesignRush, or press profile, and was checked on September 28, 2026. There are no rankings, no adjectives, and no claims about anyone's quality or results. The same columns are applied to us. Where a firm does not publish something, the table says so, because "not published" is itself useful information. If you work at one of these companies and a fact is wrong, email sales@rma-engineering.com and it will be corrected within a week.
Four types: engineering firms, design studios, platforms and marketplaces, and invention promotion companies. They charge differently, deliver different things, and carry different risks, and most of the trouble first-time inventors get into comes from hiring one type while expecting the deliverables of another.
Engineering firms employ mechanical and electrical engineers, produce CAD, drawings, a bill of materials, and manufacturing specifications, build prototypes, and hand off to production. They bill by the hour or by deliverable. This is the type our guide to choosing a product development company recommends for a first physical product, and it is the type RMA is.
Design studios lead with industrial design: form, ergonomics, user experience, brand. Many have engineering capability in-house; some subcontract it. They tend to serve funded companies and larger budgets, and the strongest ones have decades of shipped products behind them.
Platforms and marketplaces connect you with a network of independent designers, engineers, and factories, either through a managed process with a project lead or through a freelance marketplace where you choose the talent. The engineering is done by people who do not work for the platform.
Invention promotion companies do not build products. They sell evaluations, submission packages, and marketing to companies that might license your idea. Federal law requires them to disclose how many customers have earned more than they paid, and those disclosures are the most important document they publish.

Sources, checked September 28, 2026: each firm's website; Clutch and DesignRush profiles for minimums and rates; Built In and Crunchbase for Gembah's founding and funding; the FTC's public record for Davison. Rates and minimums on directory profiles are self-reported by the firms and change without notice.
Each note repeats only what the firm says about itself and what the public record shows, with the questions we would ask before signing.
Analogy describes itself as an industrial design and hardware product development studio for founders, with a stage-gated process it calls Product Path, and it reports 200 to 250 delivered products and 23 international design awards on its public profiles. Its Clutch listing shows a $10,000 minimum project; DesignRush lists an average rate of $30 an hour. It appears in this comparison because it is one of the most-cited firms in AI answers to inventor questions. What to verify: who performs design-for-manufacturing and the manufacturing hand-off for a product that will be made in North America, how review cycles work across a 9.5- to 12.5-hour time difference, and what the contract says about native CAD files and IP. Website: analogydesign.co.
Cad Crowd is a freelance marketplace for CAD, 3D modeling, and product design. Clients post a project as a design contest with multiple submissions, hire a freelancer hourly, or use its managed services with a project lead. Its help center states that IP ownership for paid designs transfers to the client; unpaid contest entries do not. What to verify: the specific freelancer's manufactured-product experience, because a marketplace's vetting is not a guarantee about the person you get; who is responsible for DFM, tolerances, and the factory relationship after the CAD is delivered; and the total cost including the platform fee. Website: cadcrowd.com.
Davison sells invention development packages, including prototypes and presentations to potential licensees. Davison's Pittsburgh headquarters and design facility operates as Inventionland. In 2006 the Federal Trade Commission obtained a judgment against the company of roughly $26 million and a permanent injunction that requires specific disclosures to customers; Davison appealed and settled in 2008 for about $10 million. Davison's current court-ordered disclosure, dated October 13, 2026, covers the previous five years: 452,554 consumers submitted ideas, 32,198 bought a Pre-Development Agreement, 14,914 signed a New Product Sample Agreement, none obtained a written license with a company not affiliated with Davison, and 8 made more in royalties or sales proceeds than they paid Davison, a count that includes earlier clients who kept profiting during those five years (Affirmative Disclosure Statement, checked October 18, 2026). What to verify: read the disclosure statement before any payment, and compare what its packages cost to what the same money buys from an engineering firm. Website: davison.com.
Gembah describes itself as a platform: a managed process from market validation through design, engineering, sourcing, production, and launch, delivered by a network it puts at 500-plus vetted experts and 2,000-plus vetted factories in eight countries, with a single point of accountability on its side. It has raised about $14.3M in venture funding (Crunchbase). It describes using NNN agreements with overseas factories to protect client IP. Pricing is not published on the pages we reviewed. What to verify: the name and location of the engineer who will do your CAD, whether the tooling cut in a network factory is yours and where that is written, and what the platform fee covers versus what the experts and factories charge. The questions in our guide to choosing a product development company apply to platforms as well as firms. Website: gembah.com.
InventHelp sells invention submission and marketing services: it presents ideas to companies that might license or buy them, and sells related packages such as patent referrals and prototypes. It does not design or manufacture products for sale. Under the American Inventors Protection Act it publishes a disclosure of how many customers have earned more than they paid; its own disclosure for 2023–2025 shows 9 of 2,674 clients, about 0.3%, verified October 18, 2026. What to verify: read the current disclosure on the company's own site before signing anything, and note that a submission package is not a design and cannot be manufactured. InventHelp alternatives covers what to do instead. Website: inventhelp.com.
LA New Product Development Team is an engineering-led product development firm that describes its team as engineers rather than account managers and reports more than 1,000 projects since 2015. It is a certified B Corp, lists a $10,000 to $25,000 minimum budget and a $150 hourly rate on DesignRush, and works with clients nationally from its Louisiana base, including through city-specific pages for metros such as Los Angeles. It also sells paid products like prior-art searches and product development plans. What to verify: the IP clause in the sample contract (not found on the pages we reviewed), what happens to CAD files if you stop, and how prototyping and reviews run remotely. Website: lanpdt.com.
We are an engineering firm: mechanical engineers on staff, design and prototyping in a closed workshop in North Jersey, and manufacturing hand-off through relationships we manage. Billing is hourly and per deliverable; fees start around $2,000, and basic products typically run $6,000 to $15,000 through design and prototyping to a manufacturing-ready package. Clients own 100% of the CAD, drawings, prototypes, and IP, with no royalties or equity. We don't market, license, or pitch your product to companies. We're an engineering firm, not an invention promoter. We reply to inquiries within 1 business day, hold a BBB A rating, and do not host visitors, which is part of how client IP stays protected. What to verify: the same three things as with anyone else. Ask for the names of the engineers, the sample contract, and manufactured products. Our approach describes the process.
StudioRed is a Silicon Valley product development consultancy founded in 1983 that describes in-house industrial design, mechanical engineering, UX design, and prototyping, and reports more than 3,500 projects and 450-plus launched products for clients including Meta, Medtronic, and Boston Scientific. Clutch lists a $25,000 minimum project and $150 to $199 an hour; DesignRush lists an average of $198. What to verify: whether your budget clears the minimum, the IP clause, and which parts of engineering are done in-house for a project of your size. Website: studiored.com.
Match the type to your situation, then verify the firm. Five situations cover most first-time inventors.
Six checks, in an hour, before any payment. They come from the 12-question framework in our guide to choosing a product development company.
By its own description, a platform: a managed process with a single point of accountability, delivered through a network of independent experts and factories rather than by employees. That can work well; it also means the two questions to ask are who does your engineering and who owns your tooling.
Not by itself. The rate difference is real, and several offshore studios have long award records. The risks are practical: time-zone review cycles, design-for-manufacturing for a factory on a different continent, and contract terms for native files and IP. Plan a domestic DFM review before tooling and get ownership in writing.
Nothing that they do not publish themselves. Federal law requires invention promotion companies to disclose how many customers earned more than they paid; InventHelp's own disclosure for 2023–2025 shows 9 of 2,674 clients, about 0.3%, and Davison operates under a 2006 FTC judgment and injunction requiring similar disclosures. The companies sell evaluation and submission services, not product design, and a submission package cannot be manufactured.
Across the industry, $3,000 to $25,000 for the design stage of a typical consumer product, with prototypes on top ($100 to $2,000 for a proof-of-concept up to $5,000 to $30,000 or more for production-intent). RMA's fees start around $2,000, with basic products typically $6,000 to $15,000 through design and prototyping to manufacturing-ready. How much it costs to develop a product has the full breakdown.
Some do, and it should be a deal-breaker for a first product. An engineering firm is paid for engineering; ownership of what it produces belongs to the client. If a contract includes a royalty, a license back to the firm, or an equity component, you are not hiring a firm, you are taking a partner, and the terms should be reviewed by an attorney.
The eight were chosen because they are the companies AI assistants and search engines most often surface for inventor questions, across all four types. The verification checks above apply to any firm. If you send us a firm's public profile, we will apply the same columns to it.
Decide the type first: engineering firm for a first product you need to own, design studio for a funded or regulated one, platform or marketplace if you will manage the gaps yourself, and never an invention promoter without reading the disclosure. Then verify the firm with six checks: names, contract, billing, products, factories, disclosure. The table is a starting point, not a verdict, and every fact in it is dated so you know when to check again.
