Sollin is a Senior Art Director at Mother and co-founder of 11:11, an up-and-coming creative agency in Oslo. She specializes in making ads that are interesting enough that nobody has to be forced to watch them.

Her career started with a homemade stunt mocking big brands for gentrifying her hometown. It went viral and won two Cannes Lions, which brought her to agencies like Droga5, Wieden+Kennedy, and eventually Mother, while still running 11:11 at home. She made brain rot for the United Nations to get Gen Z to watch an important but boring assembly, changed Norway's food waste law by rebranding a trash can, and got the prime minister and the National Landscape Architectural Association to see storefronts as part of the future landscape using 35 cardboard signs.

She was recently named top 30 rising stars of Madison Avenue by Business Insider, a Young Gun by The One Club and chosen as one of top 16 future female creative leaders by Cannes Lions. Her work has been reconized at Eurobest, Cannes Lions, The One Show, D&AD, Tribeca x Film Festival, Epica, New York Festivals, Gullblyanten Norway National Ad Awards, Visuelt and at Spellemannsprisen for Music Video of the Year.
