 Trustindex verifies that the original source of the review is Google. We recently had our company website re-designed and set up by Netgen.  They did a brilliant job, from designing it, to helping us with the key information needed, while keeping us in the loop every step of the way. They took the time to find out how our operation functions and ensured that it reflects on the website. We are very happy with the final result and would highly recommend Netgen to anybody looking to setup a website. They are very professional and pay attention to detail. Thank you to the team at Netgen.

 Trustindex verifies that the original source of the review is Google. My experience working with NETGEN was outstanding. As the lead officer responsible for the development of an accountability and case management tool for African Union Peace Support Operations, I found their team to be highly professional, technically competent, and exceptionally responsive. Despite the specialized nature of the peace operations sector, NETGEN quickly understood our requirements and delivered effective solutions tailored to our needs. Their accessibility, prompt support, and flexibility in accommodating delays related to payments and contract finalization demonstrated a strong commitment to client satisfaction. I highly recommend NETGEN to organizations of all sizes, as their adaptability, professionalism, and customer-focused approach make them a reliable and effective software development partner.
