AI Video Agent Startup Sume Closes Pre-Seed Round
Sume secures valuation over $14 million with strong early traction for its AI-driven marketing video platform.
AI video agent startup Sume announced on 25 August 2026 that it closed a pre-seed investment round, achieving a valuation exceeding $14 million. The funding round was led by Founders Inc, with participation from Kakao Ventures, Futureplay, and Bass Ventures. This funding comes as Sume demonstrates rapid traction for its AI platform, the Sume Agent.
The Sume Agent, launched last month, is a cloud-based tool designed to automate the production of marketing videos. The system allows users to input prompts, images, video clips, or product information, and then autonomously selects and combines AI models to produce finished videos. The platform has garnered rapid adoption, securing an eight-figure KRW annual revenue within a month.
AI-driven video production is seeing increasing demand, particularly in marketing sectors where high-volume content is necessary. Sume's platform addresses bottlenecks in creating consistent, large-scale video output, positioning itself as a cost-effective and efficient alternative to traditional methods. According to CEO Dohyun Lim, the platform allows users to define a video format once and then apply it across batches of new content.
Sume's strategy focuses on simplifying the video production process for brands and agencies. By automating content creation, Sume provides a replacement for the manual multi-tool workflows currently required. This capability is increasingly valued as social media platforms demand faster content cycles.
The startup operates with a small, agile team and has already launched related services such as Sume Ads, which achieved significant user adoption shortly after its release. These developments highlight Sume's potential to scale and secure a significant market position.
Moving forward, Sume aims to expand its service offerings and optimize video production further. The company expects to achieve substantial revenue growth and continue attracting interest from global markets. Observers will be watching how Sume capitalizes on its early momentum and whether it will challenge established video production platforms.
The participation of notable investors such as Founders Inc and Kakao Ventures underscores the belief in Sume's business model and technology. As Sume enhances its platform capabilities, its impact on the marketing landscape and AI video production will become clearer.
It will be important to watch how Sume navigates the competitive landscape and adapts to changes in technology and user demands. Innovations in AI capabilities and shifts in marketing strategies could present both opportunities and challenges for the company.
