“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.”

Lisa Illman President, Kritter Kommunity

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.

We can get started on your project quickly and efficiently, with minimal information needed to begin.

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 done in-house. This comprehensive approach enables us to streamline the development process, saving you time and money. Our in-house capabilities also mean we can quickly and efficiently make necessary changes and improvements.
