Rikkin succeeded the previous CEO of Abstergo after their death in January 2012. In a tape, Rikkin's predecessor encouraged him to stay on course after all he had learned from the previous Grand Masters, and reminded him that the free market would soon collapse, and that he needed to establish the New World Order before all turned to anarchy.
Later that year, Abstergo was hit by a scandal over the testing of their New Fluoride product; the United States government threatened to freeze Abstergo's assets, which coupled with the loss of an Apple of Eden in the DIA satellite accident, forced them to hasten the completion of the Eye-Abstergo satellite.

Rikkin oversaw the Animus Project supervised by Vidic and Lucy Stillman, reviewing the data obtained from Subjects 12-16. He became frustrated that it was taking a few days for Desmond Miles – Abstergo's seventeenth subject in the program – to synchronize with the memory they needed to map the locations of the Pieces of Eden, one of which would replace the Apple needed to power the Eye-Abstergo satellite.
Rikkin, David Kilkerman and Henry Liman came to the Animus Project laboratory in Rome the day after an unsuccessful attack from the Assassins. Vidic had obtained the necessary memory, to which Rikkin responded he would send teams to collect all of them, should anyone else obtain one and cause trouble in the Templars' New World.
Rikkin also ordered that Desmond be terminated, but Stillman retorted, saying that they needed him to obtain any more information on the sites from his genetic memory, so Rikkin deferred to her judgment.

Rikkin could be a rude and vulgar individual. Despite both being members of the Inner Sanctum, his emails to Vidic were often disrespectful and impatient. However, in an email written for him with other Abstergo executives, Rikkin showed the intelligence and charisma necessary to head a company.
Lucy Stillman once emailed Rikkin, requesting information on a deceased friend and ex-employee, Leila Marino. The only response she received was an out-of-office notice, despite the fact that Rikkin continued to manage his other emails during the time he was supposedly away, even sending Vidic a message warning the latter to keep Lucy from asking difficult questions.
Rikkin was also ignorant of historical facts, proven when he mistook who Guy Fawkes was, believing Fawkes was involved in the French Revolution. When corrected by Caroline Grey, he snapped at her, claiming "We are making history here, the past is largely irrelevant."
