Im not 100% sure what you are asking, maybe you could clear it up?

Are you asking about pre Colombian institutions like Aztec school organizations that survived the arrival of Europeans or Native businesses that might have a continual history that can be traced? Or when and how far back business and institutions on European models can be traced back in the Americas?

Even so I think on the face of things you may be underselling how far back even those organizations, businesses, and schools in the Americas can trace themselves back that were set up by the colonial powers. And a century isnt that high of a bar even for them.

If we are talking oldest alone there were 2 fully recognized universities operating in Spanish South America that are still intact today by 1600, Saint Thomas Aquinas University in Colombia and University of San Marcos in Lima Peru. Along with several others that have been absorbed by others or combined, many driven by groups such as the Jesuits and Dominicans.

Hell even if we just focus on the future United States there are a noted group of 9 Colonial Universities that are still operating today that were chartered and operating before the start of the Revolution in 1775. The oldest of which in Harvard was first organized in 1636, and the second, William and Mary in 1693.

Heck even to use the other example in Breweries most New World examples may give up many years on their Old World or Asian peers it doesnt make them all spring Chicks. Yuengling for instance is generally recognized as the oldest continually operating brewery in the US with their Pottstown PA location with operations starting in 1829. While North of the border Molson has continually been brewing beer in Montreal since the mid 1780's.
