A small, geographically bound family business like this is one thing, but we should pay more attention to what kind of creatures we're creating in the long run.
An LLC is a very useful legal fiction, but more and more we're seeing the effects of allowing virtually unbounded, private for profit organizations.
As just one counter-example; I'm sure there are plenty more/earlier: Siemens was founded in 1847 (edit: by building telegraph equipment and infrastructure).
Edit: I'm sure there must have been earlier companies involved in "tech" that are still relevant? Maybe let's think about "tech" as "information technology" companies?
I was originally looking for "old companies that currently work in tech", but even their original industry of copper smelting was pretty high tech for the 15th century.
If you consider banking to be information-managing tech (which it seems to me that it is), then the oldest may be either Berenberg Bank (1590) or Banca Monte dei Paschi di Siena (1472). It depends on the definition of "bank". The later is certainly a bank now, but was more like a pawnbroker in its early years.
Its constituent companies were older, though. Hollerith's original Tabulating Machine patent was filed in 1884, and his machines and punch cards were used for the 1890 census.
If any were to, I'd hope it'd be YouTube. For better or worse, it's an amazing repository of what it is to be human in the early 21st century in terms of the billions of hours of evidence that people record and upload. Imagine being an archaeologist in 1000 years having access to this.
