TutorInc is a tutoring service for international school and university students in Vienna, Austria. They provide one-on-one and small group tutoring and needed a logo to showcase their focus on math and physics. A crisp, slab serif typeface was selected to echo the academic theme in the name. The letter “O” in tutor was replaced with a light bulb icon to symbolize the moment of clarity as a student learns, and the bulb was filled with an “Angle at the Center” circle theorem to specify that those moments would be in the fields of math and physics. Using a circle theorem also presented an opportunity to bring in meaningful color and help the logo pop.
