Search headquarters of investment companies

I have approximately 900 investment companies with only names. I want to find someone who can search for the company's headquarters and a link to back it up (from a reputable source like sec.gov or whalewisdom, for example).

Example: I have the name "Squarepoint Ops Llc". I want 2 columns. One column is "United States". One column is a link to show why you make that decision, like "https://whalewisdom.com/filer/squarepoint-ops-llc". Thanks!
