Maisie's comedy career kicked off in 2017, when she entered the nationwide So You Think You're Funny? competition (which has previously been won by many of her comedy heroes, including Peter Kay, Aisling Bea, and Tom Allen). Before she knew it, she found herself with a place in the Grand Final, held at the Gilded Balloon up at the Edinburgh Fringe Festival and on 24th August she won the competition, becoming only the 4th woman to have done so in its' 30-year history. The following year, Maisie was nominated for the Best Newcomer award at the Edinburgh Comedy Awards for her debut show ‘Vague’, where she also won the Amused Moose National Comic Award.

Maisie's anecdotal material and witty charm have quickly won her praise up and down the country and she has since appeared on Mock the Week, Have I Got News for You, QI, Roast Battle, 8 Out of 10 Cats, Hypothetical and The Stand-Up Sketch Show. She also hosts the podcast 'That's A First' alongside fellow comedian Tom Lucy.
