Diatom Enterprises Industry Expertise


“I have known Denis and Diatom professionally and personally for nearly ten years. His company has done professional work for us on two occasions. The work was done on time, on budget, and to a North American professional standard.”

“Diatom Enterprises were able to provide the combination of R&D, consultancy and outsourcing services that we needed. They were very professional, well organized and always performed their duties on time and of high quality.”

“In my experience Diatom engineers display a high degree of professionalism and I am proud to have recommended them. Without them, Jiff would not have a successful long- term strategy. I will continue to recommend Diatom for their services and will look forward to working with them on future projects.”

“Diatom built two small but very critical software tools for us. They worked on day-one and have worked since. They are now old and outmoded but still working. When the environment around them changed, Diatom has been responsive, quick and generous in their response to my request to make adjustments to the code to fit the new environment.”

“After evaluating all of our suppliers and their performances, I was positively surprised about the responsible attitudes, precise observations regarding our specifications, and the orientation of teamwork from Diatom Enterprises’ professionals.”

“Diatom is a pleasure to do business with. They do high quality work, are highly motivated, and self-managing, with tools, processes, experience and good people. They work hard to make the time difference disappear and are very flexible on scheduling. Estimates have been realistic and dependable.”

“Today we are energized by the quality of workmanship and professionalism of Diatom. We set for them a very difficult task of cleaning up someone else’s mess, and they’ve come through, giving us renewed energy and confidence.”

“Working with Diatom has been a great experience. This was our first time outsourcing any of our development, and it has been nothing less than amazing.”

“I recommend without hesitation to anyone who is looking for highly competent and agile team for bespoke software design and development.”

“Our Diatom’s team was very professional, cooperative, and was highly motivated for maximum client satisfaction. Their recommendations were always in our best interest.”

“I will definitely recommend Diatom Enterprises to anyone who has software development needs. Their staff has been in par, if not better, than the onshore developers that we have had at RealtyTrac.”
