I was not familiar with the acronym ETL and it is not explained anywhere in the website! My feedback would be to at least write it once, on the first instance so others like me will know what they are reading :)
It is a common term and practice among enterprise software users, i.e. generally medium or large companies that use packaged plus custom software for their business needs.
ETL is not common among startups, because they have a different focus, infrastructure and scale.
In computing, extract, transform, load (ETL) is a three-phase process where data is extracted from an input source, transformed (including cleaning), and loaded into an output data container. The data can be collated from one or more sources and it can also be output to one or more destinations.
Thanks for pointing that out, it's actually mentioned (Extract, transform and load ...) in the very first sentence below the tagline, but if you didn't get it then it's not clear.

I'll just add:
