Dr. Zeus Inc., also known simply as The Company, is a fictional entity in a series of time travel science fiction stories by Kage Baker.

According to the stories, Dr. Zeus operates from the 24th century, using technologies of time travel and immortality to exploit the past for commercial gain. The immortality technology is limited to taking young children and turning them into cyborgs. The time travel technology only allows journeys into the past, and returns to the present. No artifacts or people can be brought forward from their own times. In addition, the technology is expensive and dangerous for normal humans to use.

History, or at least recorded history, cannot be changed. Dr. Zeus cannot save Lincoln, warn the Titanic, prevent the sack of Rome, or stop the burning of the Library at Alexandria. It can take valuable artifacts thought to be lost in these and other events, hide them and 'rediscover' them in the future. However, even without the dangers of time travel, Dr. Zeus' employees hate the past. By their time, all stimulants and narcotics are illegal, vegetarianism is compulsory, and they are disease- and dirt-phobic. They find the past's inhabitants disgusting.

To carry out its mission, Dr. Zeus sends its employees far into human prehistory, where they take children from Neanderthal and modern human families and give them the immortality treatment. These individuals are then promised a bright future in the 24th century, in exchange for working for the Company till then. Their job is to preserve cultural artifacts, valuable plants, and endangered species, hiding them in safe places till the Company can 'recover' them in the future. The cyborgs will get to the 24th century the old-fashioned way, by living through the intervening millennia. Along the way they can create others to help them, using children who would otherwise die and not affect history. They are also provided with many recordings of future culture, entertainment, and a carefully edited view of history. Dr. Zeus alone knows everything that will happen up till the 24th century.

As the series progresses, it becomes apparent that the Dr. Zeus story is itself a fiction. How they came by their technology, and how long the Company has really existed, is an unfolding mystery. Furthermore, not even Dr. Zeus knows what happens after July 9, 2355; although it is possible to send messages to the past, there is nothing from beyond that date. This is known as the Silence, and is a source of dread to both Company people and cyborgs.
