Andy Byron resigned as Astronomer CEO after the Coldplay concert kiss cam showed him cozying up with company HR head Kristin Cabot.

Tech CEO Andy Byron has resigned following his viral scandal during a Coldplay concert in Boston last week.

Andy Byron, who has found himself at the center of a social media firestorm over a Coldplay concert video, was the CEO of a tech company named Astronomer. On July 19, the company announced that Byron has resigned in the wake of the scandal.

It’s horrible because she is the head of HR! She’s involved in an extramarital affair with the CEO. Basically, how much worse of an HR faux pas could you commit?” Cafaro told The Post.

Oliver Wendell Holmes coined the term in his 1861 novel Elsie Venner, calling Boston's elite families "the Brahmin Caste of New England".

Kristin Cabot, caught in a viral embrace with Astronomer CEO Andy Byron, appears to be married to Privateer Rum founder Andrew Cabot, a member of a prominent Boston family.

Another employment attorney, William Cafaro, told The Post he believes from what he’s seen, booting Cabot would be easy, but he suspects the company and her might be wrangling over an exit deal.

The exact date of Kristin and Andrew Cabot's marriage remains unclear, though it's confirmed to be at least the second marriage for both of them.
