Without NBI's intense investigation, surveillance, and relentless research into the dark life of the Plaintiff, this settlement would not have been possible.

At NBI, every investigation starts with a commitment...

And ends with a guarantee.

 

Having been in business for over four decades, we know there are many investigations companies you can call on.  But one doesn't thrive for nearly fifty years in this industry without first having a foundation of integrity, trust, and reliability.

 

We're an investigations company that understands that 'customer service' isn't a department, it's a creed.  And because of that, we count the most prestigious law firms, insurance companies, TPA's, and corporations as our partners.

 

And for those that are seeking a partner?  We'd like to extend our no-risk guarantee: 
If you're not happy with our investigations - you only pay what you believe our performance is worth.

 

Every investigations company promises professionalism.  Only one guarantees it!
