OK, there is some confusion here. ...let's do a backstory...
For much of its history, Information Builders Inc. was known as IBI. A sales rep from Information Builders joked once to me that if he went into a big company and told the receptionist he was from IBI, that person would typically call the executive and say, "IBM is here to see you."
For awhile, IBI was probably okay with being confused with IBM.
Today, they are known as Information Builders. The old IBI moniker is, well, old.
Many of my blog readers seem to be confused as to who owns WebFOCUS. Information Builders does, but just to add a quirk to this, IBM does resell WebFOCUS on their mid-range box under a different name: "DB2 Web Query."
In addition to the similar acronyms, another source of confusion could be Information Builders' heritage as a Big Blue mainframe software vendor. IBM provided the hardware, operating system, and databases and IBI provided the software on top of that.
That partnership worked for decades, but IBM changed the game when they acquired Cognos and became Information Builders' direct BI software competitor. IBM put it again to Information Builders when they bought SPSS, at the time the statistical software partner for WebFOCUS (forcing IBI to switch to the open-source R product).
Despite all of this, there must still be some type of "coopetition" between the two software vendors.
