HMH, formerly known as Houghton Mifflin Harcourt, is an adaptive learning company serving K-12 education. The company unveiled its current visual identity on July 18, 2024, a refresh that included a streamlined name and a new logo designed by the global creative consultancy Lippincott.[1][2]

Design and History

The 2024 rebrand marked a significant shift for the nearly 200-year-old publisher, which had been known as Houghton Mifflin Harcourt since a 2007 reorganization. The company dropped the full name in favor of the HMH moniker, a nickname it had long been known by, and adopted a new logo and visual look.[3]

The new logo features three ovals that move in an upward trajectory. According to Lippincott, the shapes allude to HMH’s expertise in curriculum, assessment, and professional development, as well as the relationship between students, teachers, and administrators. The ovals interact as bodies held together by mutual forces of attraction, moving in constant motion, change, and growth.[2][4]

The design drew from HMH’s previous identity, which was also built from geometric shapes and created by Lippincott. That earlier mark, introduced around 2012, replaced a long-standing dolphin colophon with three shapes: a triangle, a cone, and a circle, illustrating ideas of curiosity and discovery.[5][6][7]

The 2024 identity was developed around the brand idea “Growth in motion,” which captures HMH’s promise to power learning that adapts to student needs. The rebrand was intended to communicate the company’s transformation from a traditional textbook publisher to a digital-first adaptive learning company.[2][4]

Meaning and Symbolism

Lippincott documented the symbolism of the three ovals in the current HMH logo. The shapes represent HMH’s three core areas of expertise: curriculum, assessment, and professional development. They also symbolize the interconnected relationship between students, teachers, and administrators. The upward trajectory of the ovals embodies continuous progress and growth.[2][4]

The earlier geometric logo, introduced around 2012, was designed to illustrate ideas of curiosity and discovery, with a triangle morphing into a cone and then a circle. That identity was part of a brand refresh that replaced the company’s historic dolphin colophon, which dated from the 1880s.[6][7]

Typography and Design

The 2024 visual identity includes a vibrant color palette featuring pink-to-orange gradients, bold visual devices, and clean, simple typography with a sense of personality. The trademark filing for the new logo describes the mark as consisting of the stylized wording “HMH” in black, with three oval designs featuring pink and orange color gradients to the right.[8][9][2]

Lippincott also developed a signature brand voice for HMH, described as the “creative co-pilot,” which emulates how the company works with educators as a skilled and steadfast partner.[2]
