Which company operates the Animus technology in the Assassin's Creed series?

Abstergo Industries operates the Animus technology in the Assassin's Creed series.

Abstergo is a multinational corporation and the modern-world face of the Templar Order. Its researchers use the Animus to access genetic memories carried through a person's ancestry. The technology allows a subject to experience historical events without literally traveling through time.

The company is presented publicly as a powerful, innovative corporation, but its hidden purpose is to locate powerful artifacts and shape society according to Templar goals. This double identity connects the modern storyline to the historical adventures shown inside the Animus.

Abstergo is not the same thing as the Animus itself. The Animus is the machine or system, whereas Abstergo is the organization that develops and deploys it. The Assassin Brotherhood opposes Abstergo's Templar agenda, making the corporation one of the franchise's central recurring antagonists.
