Notion, a productivity software company, has reached a significant milestone by surpassing 100 million users. Founded by Ivan Zhao, Notion faced numerous challenges in its early years, including a near-collapse in 2015 when users did not embrace the software, and the company ran out of funds. The founders laid off their entire team and relocated to Japan to reinvent their product. Despite these setbacks, Notion persisted and rebuilt its platform four times before gaining traction. The company's breakthrough came in 2018 with a successful launch on Product Hunt, which played a crucial role in its growth. By 2020, Notion had reached 1 million users, and its user base has expanded exponentially since then. Notion's journey began with just 1000 users and saw significant growth by 2021. This achievement underscores the resilience and dedication of the Notion team, led by Ivan Zhao and Akshay Kothari.
