Customer Testimonials

  • “Merge is undoubtedly one of best software vendors I have ever worked with. Not only do they have a great product, but every member of the team is skilled and experienced in their unique discipline and an absolute pleasure to work with. I can’t thank them enough for all their great work to date, and I look forward to many more years of successful collaboration.”

    - Project Systems Manager

  • "I have to admit, starting a new clinical trial with a perfect EDC system is still not that easy, but with the help of Merge eClinical we did it. The team was a great help, which made all this EDC work so much more simple for me and our team."

    -Director of Research

  • "I cannot believe what I just saw. You guys are highly organized, and I thought I was going to a simple EDC system today, not one this rich!"

    -New Customer on their first eClinicalOS study

  • "We are speaking about eClinicalOS for a few of our clients. We are going to be building an entire go-to-market strategy with this product. We had a great internal meeting and we all pushed hard for this solution, after our project managers were able to build a study without any programmers. Unbelievable!"

    -CRO Partner, seeing the efficiency of one person building an entire study

  • "Having spent the last 20 years working in the industry and with EDC systems since their start in the mid 1990s I am rarely impressed. However, having taken the time to work through the on line training I do think Merge has an EDC product with eClinicalOS that is going to differentiate itself in the market place as a low entry cost, full featured and easy to use EDC system."

    -EDC Consultant, charged with selecting tool of choice for various clients

  • "Thank you for the very rapid response! I am pleased with the capabilities you outlined already, and I am even more excited about the evolution of the product in the future."

    -Customer/Director of Data Management

  • "We did our site initiation today. And at first blush, they were really excited with the eClinicalOS. Everyone commented that the system looked pretty intuitive and was very user friendly."

    -New Customer / First eClinicalOS Study, conducting training with their Sites

  • "I am completely on-board with the eClinicalOS vision. In my past, I have been a DM, designer/software programmer for in-house DM systems, consultant, and now in management. I am a techie geek at heart so I am happy to see that someone else had the brainy idea to create a largely pre-programmed EDC system. Traditional costs for EDC scare folks away and they resort to paper. Kudos to your group for launching at this price-point."
