Duolingo has made a definitive statement that it will never open an office in San Francisco, reinforcing its commitment to its Pittsburgh headquarters. The company argues that being based in Pittsburgh allows it to avoid the high costs and trends associated with Silicon Valley, which they believe helps maintain their unique culture. In a LinkedIn post, Duolingo emphasized that Pittsburgh is not a fallback option but a strategic choice for fostering innovation and meaningful work. The company also has offices in Detroit, New York City, and Seattle, showcasing its belief that startups can succeed in various locations beyond the Bay Area. This decision reflects a growing trend among startups to seek environments that align with their values rather than conforming to the pressures of established tech hubs.
