A 2.6 million employee TL: 10/11 company that uses patented "innovative technologies such as intelligent machines, spacecraft, virtual reality and artificial life" mean that the whole planet is moving toward TL: 10/11 in the relevant field. 99%+ of the planet are still operating at TL-8, but we are out of the "experimental laboratory" at this stage.

You can have some secret labs working on high-TL stuff (although the spacecraft one is probably out unless you also have very high TL strealth tech.).

But you cannot claim to have a whole megacorp openly TL10/11 on a TL8 world and keep that setup stable without coercion.

Regarding the "indentured slaves" : the only way to enforce Duty (Genesis Inc, Involuntary) [-15] + Secret (death, illegal investigations) [-30] given Enemy (rival companies) [-20] and Enemy (The Worldwide Media) [-10] is by using company wide mind control (likely using tl11 drugs, so why not, its your game) but even with an AI running security, one mistake and its game over - welcome to jail.

Or you take over a minor country (codename: latveria) and turtle up.
