ESX

ESX is a full service software solutions company. The job it does: building software for you when nothing off the shelf fits.

It makes the most sense for companies with a specific process to automate. As a small company team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

ESX is based in Houston, Texas and founded in 1999. Their site is esxinc.com.

Our checklist for this category: portfolio relevance, who owns the code, and how they handle changes. Ask for a trial on your own data, not a canned demo.

If you have worked with ESX, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
