Twinkl provides teachers, tutors and parents with educational resources such as lesson plans, reading book collections, and maths worksheets. Its website offers 750,000 digital resources and attracts an average of 14m visits a month. Jonathan and Susie Seaton set up Twinkl in 2010 from their spare bedroom, after Susie, a teacher, could not find resources for her lessons. The Sheffield-based firm now operates in more than 200 countries and employs over 700 people. The company also runs TwinklHive, a business accelerator for edtech start-ups.
