zvelo

zvelo provides contextual categorization technologies and databases, including malicious website detections and blacklist solutions. The job it does: building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. As a mid-sized company team themselves (51 to 200 people), they tend to serve customers of a similar scale best.

zvelo is based in Greenwood Village, Colorado. Their site is zvelo.com.

Things worth asking about: 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 zvelo, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
