We work for inventors and startups who want to:

  • Develop a new product
  • Market the product independently
  • Attain profitability quickly
  • Reduce initial investment expenses
  • Minimize day-to-day costs

We offer the minimal services you need to get started and the necessary expertise to develop a great product.

Some product development companies make money convincing you that you can’t handle this on your own; we will show you how.

With the design, engineering, and prototyping in-house, we can handle complex projects and keep them secret, so you can be sure your product works before you patent it.

Before you spend thousands on illustrations, submissions, and licensing services, talk to our engineer first. You might be able to get a working prototype for the same cost.

No need for a walk-in. We have been working with customers remotely since we started in Austin in 2001.

Where Innovation Meets Expertise

We are a leading provider of end-to-end physical product development services dedicated to helping small businesses bring their ideas to life. We have a passion for innovation and a commitment to delivering top-quality results.

Expert Product Design Solutions

Whether you're looking to create a new product from scratch or improve upon an existing design, we have the expertise and knowledge to help you achieve your goals. We work closely with our clients to understand their needs and develop custom solutions that meet their unique requirements.

Your Independent Engineering Firm

We take pride in not answering to a factory and maintaining complete control over our design and engineering process. Our licensed engineering firm focuses solely on physical product development. Unlike other firms, we don't offer services such as advertising; instead, we focus solely on delivering the best product possible to our clients.


End-To-End In-House Physical Product Development

We specialize in hardware design, software coding, physical product design, and prototype fabrication - all of which is done in-house. This comprehensive approach enables us to streamline the development process, saving you time and money. Our in-house capabilities also mean that we can quickly and efficiently make changes and adjustments as needed.

From Napkin Sketch to Reality

Despite our small size, we've completed over 200 projects for clients across a wide range of industries. This extensive experience has given us a deep understanding of what works and what doesn't when it comes to designing and developing physical products. We can get started on your project quickly and efficiently, with minimal information needed to begin.

What Our Clients Say

“Our company worked intimately with and relied heavily upon McLellan Engineering. We could not have succeeded as quickly as we did – designing and readying our new consumer product for the marketplace – without their expertise and industry insight.

Seth A. Hodes

“Working with McLellan Engineering made my invention a reality. Bruce not only provided great insight to my project, he took the time to discuss the entire process of designing, manufacturing and bringing the invention to market. I highly recommend using McLellan as a resource for any new product.”
