I have been working with them for over 5 years now as an Account Executive handling their account management team in Europe (Poland).
They are always reliable when it comes down do delivering results - they will listen closely what you want from your campaigns/projects then develop solutions accordingly! Nothing much so far but i am sure if there is anything that we need improvement of our workflows or processes than this would be one thing where my colleagues can help me out by giving feedbacks which has helped improve things already!! Highly recommended. We use InviQa's platform mainly because its easy enought manage all aspects related marketing activities such us tracking ROI etc.,.
