Yeah, I'm sure some system like that exists, although I'd assume that would be more in the CIA's purview. I'd be surprised if they kept a broad swath of data for most people though as the tech companies already do it and it's constantly up to date. If needed, a fed lawyer can work through the FISA court and the tech companies are obliged to provide the records.
According to the information I have, the CIA is unlikely to be involved with SIGINT of that type. It's just not their role. I agree that most of the information the NSA might collect will come from publicly available sources like data brokers, particularly if US citizens are involved. However, what I was talking about concerns real-time capabilities and predictive power, it's very different from targeted surveillance and anything involving courts.
