Sam & Julia - The Mouse Mansion

SAM & JULIA is a Dutch startup renowned for its successful book series, The Mouse Mansion, created by Karina Schaapman. The unique backdrop for the books, The Mouse Mansion, is entirely crafted from waste materials, vintage fabrics, and cardboard boxes. In addition to being on display at the museum and brand store in Amsterdam, the Mouse Mansion has inspired 22 published books about Sam and Julia. Since 2011, the series has sold over 1 million books internationally in 27 languages. The company has also developed a range of arts & crafts products and plush toys, allowing fans to construct their own mouse mansions. Moreover, a brand-new animated series based on the books is set to launch internationally on TV and streaming platforms from 2024.

The startup, founded in 2015 and based in The Netherlands, secured its last investment through a Venture Round at 01 January 2020 from Boralis BV. The company's diversification into publishing, products, licensing, and animated series presents promising growth potential, with a strong appeal to a global audience. The success of the book series and merchandise sales, coupled with the upcoming launch of the animated series, positions SAM & JULIA as an attractive investment opportunity in the media and entertainment industry.
