Review on Design Integrity by Allan Lambert

I have worked with them since they first started up their business about 10 years ago. They are great at what they do! The team has been there for us throughout our entire growth cycle. We've used them as consultants to help develop key strategic components for our products - primarily software tools but also hardware devices. Their knowledge base is deep and comprehensive and when your company grows quickly it's important that you find people who can keep pace. One thing we dislike is how much time passes between projects/engagements so if you're looking for someone long term this may not be ideal (we need more consistent work). Definitely use these guys! Great experience working with them over multiple engagements which allowed us to build a strong relationship and trust with them.
