Charles is a great and thorough writer. I say thorough because he fully researches the topic he is asked to write about and therefore has quotes and statistics that are trustworthy. He took my needs for a White Paper, interviewed me to really understand what I was trying to say and turned out a wonderful final piece. I highly recommend him for your needs.

I recently hired Charles to do a research report for an SAAS project we’re developing. He was generous with his time and delivered a thorough report that told me just what I needed to know.
In addition, Charles is what Malcolm Gladwell calls a “connector.” Once you’re on his radar he’s generous with his connections and smart about who will benefit from knowing him.

Charles did a great job for us, constructing code and systems to provide management processing for our startup business. He was able to integrate data from Unix and Windows systems that enabled us to increase cash flow by speeding our transaction processing. I would heartily recommend him as a strong technical player on any team.

Charles is very knowledgeable about a wide variety of IT issues and has helped troubleshoot many different problems for us.

Stephen Harris Testimonial
Charles has a strong sense of integrity and professionalism when approaching an assignment. For an important client of mine, he did an incredible amount of due diligent discovery and provided insightful recommendations. He presented alternative solutions to some very tricky problems. It was a difficult assignment, yet Charles kept his focus on the customer and his mission.
From my many years of managing and hiring development resources, I can endorse Charles highly for the reasons above and more. You will have a strong ally on your team with Mr. Costa.

Brilliant!! Just brilliant. Charles gave us the ability to make smart decisions without any guesswork. : ))
As part of our research to launch a local ice cream brand, we sought the assistance of Charles Costa. The assignment we gave to Charles was to compile 20 of the most difficult questions to answer regarding marketing, learning our direct and indirect competition and the likelihood for success depending on 6 different approaches.
We got more than we wanted. We were surprised by 80% of his answers. Most of the assumptions we were making were COMPLETELY WRONG and off target. Moving forward without his sources and insightful answers, we might’ve landed flat on our faces.
For a little under $4,000, we are now saving $20K or more in trial and error tactics that would have led us nowhere. It is the best money we’ve ever spend for our client. We are extremely happy and definitely using him before we start anything.
