We dont' like to brag, but we don't mind letting our customers do it for us. Here are a few nice things folks have said about our themes over the years.
Beau Cronin, Partner at The Data Guild
“Speaking as a long-time data person, this is one of the most exciting products I’ve ever seen. Something I’ve wanted for years without knowing I wanted it. Great Expectations is going to dramatically reshape the way data teams work together.”
Matt Gee, CEO at BrightHive
“BrightHive combines and aggregates data across many state and local government entities. The data is so messy and inconsistent that we couldn’t do what we need to do without a tool like Great Expectations. This product literally makes the rest of my business possible.”
Kamla Kasichainula, Data Engineer at Calm
"Now that we're using Great Expectations we get notified ahead of time when data does not look right, giving us time to investigate and alert data users before they find out themselves"
Elizabeth Sander, Sr. Data Scientist, Civis Analytics
"I wanted to set up my project in a way that someone else would be able to understand what I expected the data to be. GE was really useful for documenting my expectations about the data in a structured way"
Gerry Manoim, Engineer @ Quantopian
“Great Expectations got everybody on the same page on what data should look like. There is a lot less mental overhead of every team member tracking that.”
