FastLabel

AI · Tokyo, Japan · Founded 2020

Offering an AI data platform that supports end-to-end data generation, version management, annotation automation, model experiment management, and MLOps construction MoreLess

Established in January 2020 by co-founders Takeshi Suzuki and Eisuke Ueda, FastLabel Inc. operates as a critical data partner for companies developing artificial intelligence. The firm addresses a significant bottleneck in AI development: the creation and management of high-quality training data. CEO Takeshi Suzuki, a software engineer with over 15 years of experience in scalable enterprise solutions and cloud-native technologies, co-founded the company based on the hypothesis that creating training data was a major obstacle to AI's societal implementation. This vision drives FastLabel's mission to create the AI infrastructure necessary to elevate Japanese industry to a world-class level.

FastLabel provides an AI Process as a Service (AIPaaS) platform, offering comprehensive support for the entire AI development lifecycle. This encompasses data collection, annotation, model development, and MLOps. The company serves large enterprises and startups, including prominent names like Panasonic, Sharp, and NTT DOCOMO, across various sectors such as autonomous driving, medical AI, robotics, and manufacturing. Its business model combines professional services with product offerings. Revenue is generated through annotation outsourcing services and subscriptions to its integrated platform, which includes tools for dataset management, data annotation, and MLOps.

The core of FastLabel's offering is its AI data platform, designed to handle all types of unstructured data, including images, videos, and audio. It provides fast and highly accurate data annotation, or tagging, which is essential for training AI models to interpret data correctly. Features include real-time visualization, data analysis, and collaboration tools. The platform streamlines the time-consuming pre-processing stages of AI development by semi-automating annotation and offering robust data management capabilities. The company has successfully raised approximately $22 million over several funding rounds, with notable investors including Sony Innovation Fund, Salesforce Ventures, Panasonic, and Marubeni, reflecting strong confidence in its growth trajectory.
