Cofounder and Chief Product Officer Pete DeJoy is currently serving as interim CEO,” a rep for Astronomer told Page Six late Friday night.

Astronomer announced that it was investigating CEO Andy Byron and HR Chief Kristin Cabot after they were spotted at a Coldplay concert.

The wife of Astronomer CEO Andy Byron, who was caught on a jumbotron at a Coldplay concert embracing his company's chief human resources officer, changed her last name on Facebook before deactivating her account. Megan Kerrigan Byron removed her last name and then swiftly deleted her Facebook account following the viral cheating allegations.

Cabot was just appointed to her position in November, and her and CEO Andy Byron, both married, were quick to gush over one another.
