I suspect that may be because you are familiar with the context.
I now know what they do, thanks to these comments, but that blurb I quoted is almost the Platonic Ideal for "Marketing Dross," and tells me exactly nothing, in many words.
At this point one my argue who Unity writes their blog posts for. But then again if you simply filter out the marketing speech, you'll end up with a pretty good, simplified description:
>If you don’t know ironSource, they bring a proven record of helping creators [...] bringing apps and user experiences to life. ironSource’s suite of tools and solutions provides [...] apps with the monetization, marketing, analytics, and discovery capabilities they need to build and run scalable app-based businesses.
Fair 'nuff, but I've spent most of my adult life, trying to explain fairly arcane technical stuff to non-technical people, so tend to use the vernacular.
I'd probably say something like "IronSource provides infrastructure to help game distributors make money off ads and measure the way their games are used."
Maybe also followed by "And they will make us FREAKIN' RICH!"
