Toss Lab

Toss Lab, Inc. is a Seoul-based software-as-a-service company founded in 2014 whose flagship product is JANDI, an enterprise communication and collaboration platform. JANDI organizes work around topic-based chat rooms and group or one-to-one messaging, and adds task management, file sharing with permanent storage and search, video conferencing, organization charts for locating colleagues by department, a "board view" for company announcements and reports, read receipts, a secure file manager for confidential documents, and an administrator dashboard. It connects to third-party tools including Google Drive, Dropbox, Trello, JIRA, GitHub and Zoom, and is available through desktop and mobile applications with cloud-based storage. Messages and files are encrypted, which the company positions as a response to corporate concerns about information leakage when employees use consumer messengers for work.

The company describes JANDI as designed for workplace communication in Asian markets, including integration with region-specific legacy systems and local onboarding support teams for enterprise customers. Video meetings supported up to 100 simultaneous participants as described in 2020 company material, with the platform reported to support up to 300 participants at the time of the Series B. Supported interface languages include English, Chinese, Japanese, Korean and Vietnamese.

Founder and CEO Kim Dae-Hyun (also referred to as Matthew or Matt Kim) previously held roles at venture firms and larger companies, including the T-Money transit card operator and an early Korean social commerce firm, and cited inefficient document approval and information flow at work as the origin of the JANDI concept."]

Founding story

Toss Lab was established in 2014. The company name combines "toss," meaning a throw, with "lab" for laboratory, reflecting an intent for employees to voice ideas freely while researching more efficient office communication. CEO Kim Dae-Hyun said his prior experience at venture firms and large companies — including the T-Money transit card provider and Korea's first social commerce company — exposed him to inefficiencies caused by poor communication and slow approval processes, leading him to develop JANDI as a workplace collaboration service. Some sources list Daniel Chan as a co-founder alongside Daehyun Kim.

Business model

Toss Lab sells JANDI as a cloud-based subscription collaboration platform to companies, serving customers from small and mid-sized businesses to large enterprises with thousands of employees. During the COVID-19 pandemic the company offered the service free of charge to companies beginning in February 2020, and JANDI was selected under a National IT Industry Promotion Agency program in which the government subsidised part of the fees for cloud services used by small and mid-sized firms.
