      Web Development Review from Greg Walker

      Nikki and her team were great. Through Skype and email, Nikki managed to navigate the time difference to the best of her abilities and work was completed successfully. Nikki herself was always friendly, reliable and professional and has been one of the best project managers I have had the pleasure of working with. In her absence, I also worked with Jai Prakash who was equally as skilled at his job. In terms of quality of work, we were happy with the results of the translations completed and with globalcamps.net being built. The developer team clearly worked tirelessly and I thank them all for their hard work, commitment and talents. It was with great sadness that the decision was made to migrate our services but I sincerely hope my paths cross with Nikki and her team again in the future. I wish the whole crew good luck and success for the year ahead. Many thanks.

      it was such a pleasure working with App Founders and just how easy and professional they were. I quickly realized how the industry is full of thirsty, needy bots and scammers I’m trying to get your attention, but tons of unsolicited phone calls and texts. Dealing with these guys was a breath of fresh and definitely showed up in value above all the rest.

      It has been wonderful working with Rhashiva from CBI over the past several months, as he and his team have been helpful in identifying areas of opportunity and coming up with strategies to improve our website's SEO. He is extremely communicative and easy to collaborate with. We've set several SEO goals for this quarter and I am looking forward to seeing how CBI's efforts can meet these targets.

      More than two years ago I hired CBI to help manage my SEO during a new website launch. The maintained and improved our orgranic traffic during this complex project. I was confident that I had a very technically capable team watching for anything that needed addressed during this time, things that I wouldn't even know to look for. I extended our working arrangement and they have worked with us on our website and SEO ever since, over two years now. I view CBI as a very important part of my company, trust them 100%, and enjoy working with them. They are one of the few companies that over-deliver. Highly recommended
