Merrill, Asukaga, & Finch

The Merrill, Asukaga & Finch offices are located in the top floors of a centrally located skyscraper. Access to these floors is restricted to those with an appointment. Generally, they aren't taking new clients, except by referral.
If you had money in Night City, and wanted more, or just wanted it safe, the people with who to talk were Asukaga & Finch. They were, without a doubt, the top people in investments of all kinds, from stock to real estate to frog-farming futures.
However, if you did't have a good deal of money in the first place, they weren't interested – the commission on a 1000 eurodollar investment wasn't worth their rather expensive time. Because the company tends primarily to corporations, many find their expensive and impersonal approach to be off-putting, and prefer to take their business elsewhere.
The high caliber of service that Asukaga & Finch has offered throughout the decades continues to attract many of the richest and most powerful people in the world. If, for some reason, they were to go bankrupt, some of the greatest powers in the world, both legal and illegal, would be overturned.
