Slader's Overview

Total employeesN/A (Company acquired; original employee count not readily available, integrated into Quizlet's ~500-700 employees)
HeadquartersNew York (historically inferred)
Founded2010

Slader was a popular online learning platform and mobile app that provided crowdsourced and expert-verified step-by-step solutions to textbook problems across a wide range of subjects, including math, science, social sciences, literature, and foreign languages. It was particularly favored by high school and college students seeking assistance with their homework and understanding complex concepts. In early 2021, Slader was acquired by Quizlet, another major educational technology company. Following the acquisition, Slader's content and functionalities were integrated into the Quizlet platform, and the standalone Slader website and app were eventually phased out. While the Slader brand is no longer active as an independent entity, its extensive library of textbook solutions continues to serve students as part of Quizlet's offerings.

HQ Function

Historically, Slader's HQ would have managed platform development, content acquisition, user support, and business operations for its textbook solutions service.

Notable Features:

As a digital-first company, its physical presence was likely functional and focused on technology and content teams, rather than extensive architectural features.

Work Culture:

Likely a startup environment: fast-paced, innovative, focused on educational technology, and dedicated to helping students succeed academically.

HQ Significance:

Slader's significance lay in its vast database of user-generated and verified textbook solutions, making it a go-to resource for students struggling with homework.

Values Reflected in HQ: Accessibility to educational resources, collaborative learning, student empowerment.

Location:

While Slader itself was primarily focused on the US market, its acquisition by Quizlet means its content and legacy now contribute to a platform with a significant global reach. Quizlet is used by students and educators in over 130 countries, supporting learning in multiple languages and across diverse educational systems. The integration of Slader's textbook solutions enhances Quizlet's ability to serve high school and college students worldwide.
