Later he formed his own company, Pym Technologies, and passed the title of Ant-Man down to Scott Lang when his own former protege Darren Cross attempted to sell his technology, the new Yellowjacket Suit, to several buyers, including HYDRA and the Ten Rings.
Thanks to his recruitment of Lang to stop Cross, and Lang’s successful escape from the Quantum Realm, Pym came to terms with losing his wife Janet van Dyne to the said realm years earlier, because he thought she could be alive in there. For two years since 2016, Pym developed a Quantum Tunnel capable of traversing across the Quantum Realm.

In 2018, Pym and his daughter Hope van Dyne initiated a plan to rescue her from the Quantum Realm, but this proved problematic when Ghost and his former colleague Bill Fosterhad conflicting ulterior motives. Nonetheless, Pym was successful in rescuing his wife with Lang and Van Dyne's help.
Not long after, Pym and his family became three of the trillions of victims in the Snap.

It wasn't until 2023 that Pym was resurrected in the Blip. Despite the tension between him and the Stark family, Pym was in attendance at Tony Stark's funeral after he sacrificed his life to wipe out the time-displaced Thanos and his armies.
