Upstage: AGI for Work

Upstage is a pioneering South Korean artificial intelligence startup specializing in document processing and large language models. Recently, the company secured $72 million in Series B funding to facilitate its global expansion, particularly into the U.S. market. This recent financial boost brings Upstage’s total funding to an impressive $100 million. The company’s innovative technology and ambitious growth plans position it as a significant player in the global AI industry.

Idea and Product

Upstage’s core offerings include a sophisticated document processing engine and a proprietary large language model named Solar. These products are designed to enhance the efficiency of processing both physical and digital documents across various sectors such as e-commerce, healthcare, finance, and legal industries. By allowing users to interact with data through natural conversational language, Upstage dramatically simplifies the way enterprises handle document inquiries and data extraction.


Upstage operates in a rapidly growing segment of the AI market, focusing on document AI and language processing solutions. With a proven track record in South Korea, the company is now looking to replicate its success on a global scale. The demand for AI-driven document processing is particularly high in industries like finance and healthcare, where data accuracy and management are critical.

Business Model

Upstage generates revenue through the deployment of its AI solutions, including on-premises installations and API integrations with platforms like Amazon SageMaker JumpStart. This model allows the company to cater to a broad range of enterprise needs, providing flexibility in how its technologies are applied within customer operations. Upstage’s strategy includes expanding its customer base internationally, leveraging its recent funding to scale operations and enter new markets.


At the heart of Upstage’s product suite is its use of optical character recognition (OCR) technology coupled with its large language model, Solar. This integration allows the rapid digitization and understanding of diverse document types, boasting a high accuracy rate even under challenging conditions. The technology’s ability to adapt to various industries and its scalability underscores its potential in the global AI landscape.

The continued support from existing investors, such as SBVA (formerly SoftBank Ventures Asia), highlights confidence in Upstage’s strategic direction and technological foundation.

Achievements and Milestones

Since its inception, Upstage has quickly become one of the top-funded AI startups in South Korea.
