Predictable Hardware Report

Want to bring a new electronic hardware product to market faster, cheaper, and with less risk

This report is a preliminary product design with detailed cost analysis for your new electronic hardware product. It's designed to be a first step for anyone new to the process of developing and launching a hardware product.


"Gave me all the information I needed to move forward with confidence."

Nailed down all cost aspects of production and included a development timeline... invaluable information to have for any product launch. The ability to dig down from macro view to details in a single document has infused a much needed level of organization. The high level of detail allows me to communicate costs with stakeholders with great confidence. The engineering review and email consultations were critically important to understanding not only detail but how the overall process of production works.
