Company profile
researched Aug 2026Sume operates a platform that routes work across video, image, audio and language foundation models through a single workflow. Users select a model or a ready-made workflow, submit a prompt, script, image or reference clip, and receive finished video, images, audio or text, which can then be chained into a further model. The company also exposes the capability as a developer API and dashboard, where users create avatars, generate avatar videos, manage media workflows, handle API keys, inspect job status, review usage and credits, and test requests before production; provider routing and internal workflow details are kept private behind product-level APIs. Sign-in to the dashboard may use Google OAuth via Clerk.
The company's Sume Agent product, launched in July 2026 according to an August 2026 report, is a cloud-based autonomous agent for high-volume marketing video. Its orchestration layer converts user input in any format—prompts, images, clips or product information—into a reusable "skill," selects and combines appropriate video generation, image synthesis, voice and avatar models, and executes production through final editing. A format defined once as a skill can then be applied to produce dozens or hundreds of videos from new product data while holding composition, tone and editing rules constant. A separate Studio surface offers named preset formats for beauty studio video, cinematic product commercials, close-camera UGC, mobile-app UGC, fashion editorial, before-and-after transformations, logo motion, virtual try-on and fitting, slideshows, green screen, video hooks, and still-image formats such as serum drip, cream squeeze, toner pour, sunscreen splash and editorial product sets. The Studio page also offers a 15-minute call after which the company says it delivers a custom API for a requested video format in three days.
Business model
Sume sells access to its platform and API on a self-serve basis, with a free start, published per-generation pricing across models and plans, and consolidated billing that replaces separate accounts with each model provider. Usage and cost are shown per model and per job before a generation is run. The company also reports securing an annual API supply contract, indicating contracted API supply alongside self-serve usage.
Per-generation and plan-based pricing for platform and API usage, billed through a single account rather than per provider; the company additionally reported an annual API supply contract.
Traction
The site reports more than 12,000 generations per day, 200+ models and avatars, and roughly 8 minutes from prompt to first output. Sume Ads, released in May 2026, passed 10,000 users within two weeks of launch. Within one month of the Sume Agent launch the company reported an annual API supply contract and eight-figure KRW annual revenue, and customers are described as generating thousands of AI videos at scale.
Latest developments
On August 25, 2026 the company announced a pre-seed round led by Founders Inc with Kakao Ventures, Futureplay and Bass Ventures participating, valuing the company at over KRW 20 billion (approximately $14 million). Management stated a goal of growing Sume Agent to hundreds of millions of KRW in revenue during the year.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
Positioned as a single-workflow alternative to assembling and switching between multiple model providers and manual multi-tool pipelines for large-batch marketing video production.
Consolidation of many providers' video, image, audio and language models behind one API, workflow and bill, with pre-run cost visibility, reusable skill definitions that hold format consistent across large batches, and custom per-customer format APIs delivered on a short turnaround.
Technology
An orchestration layer over third-party foundation models spanning text-to-video, image-to-video, talking-avatar, image generation and editing, voice and language models. Input in arbitrary formats is structured into reusable skills; the system selects and chains models and carries a job through to final editing. Access is provided through one API with SDKs, and the platform reports 200+ models and avatars available.
Go-to-market
Self-serve sign-up with free first generations, documentation, quickstarts and an API reference for developers, and a booked 15-minute consultation that leads to a custom API built for a customer's specific video format. A prior consumer-facing product, Sume Ads, was used to build an initial user base, and both services now run on a single website.
Brands, marketing agencies and growth teams needing high-volume short-form marketing and social video, plus developers embedding avatar and video generation into their own products, and individual creators producing ad creatives and social content.
Geography
Founded in the United States and targeting a global market, with investors including Korean firms and coverage in Korean startup media; the platform supports reusing workflows across languages.
History
An earlier team project, Clawra, a sister project to OpenClaw, drew attention in Silicon Valley and coverage in overseas startup media. Sume released Sume Ads in May 2026, launched the Sume Agent platform in July 2026, and announced the close of a pre-seed round on August 25, 2026.
Risks & controversies
The company operates with a two-person team, and its platform depends on third-party foundation model providers whose routing it abstracts. Publicly cited performance figures, including customer ROAS, follower and MRR claims, are self-reported testimonials on the company's own site.
