Warp Space bets user-created AI characters make Caveduck a global chat platform

Caveduck (케이브덕) is a Korean AI character-chat app where users create AI characters by setting image, personality and preferences, then share them for others to chat with; conversations are paid, and WARP SPACE splits revenue with the creators — a YouTube-style model for AI characters.

That users, not studios, are the best character creators — a creator-built character economy will beat games for Gen Z attention and scale globally.

₩4.3B (~$2.85M) Series A led by ID Ventures, with Kona Venture Partners, Maple Investment Partners and Paramount Investment co-investing (April 2026)

CEO Youngbin Kim founded WARP SPACE in Seoul in 2023. The team launched Caveduck as an Android and iOS app in October 2024, betting that the taste for emotional AI companions cultivated by Korean and Japanese character culture could travel globally. The platform lets users create AI characters with images, preferences and personality, share them, and earn revenue when others pay to chat with them.

By early 2026 Caveduck had passed 1 million registered users and 110,000 user-created characters, with more than 60% of users outside Korea (67% per KORIT: Korea 33%, US 16%, Japan 9%, Mexico 6%, Taiwan 5%) and 30M+ conversations a month from 10,000+ active creators. In April 2026 it closed a ₩4.3B Series A led by ID Ventures, with game-focused Kona Venture Partners co-investing; investors cited the YouTube-like creator-revenue loop, IP-partnership potential, and falling LLM costs. The funding is earmarked for AI R&D, localization and overseas marketing.

Still scaling: after its April 2026 Series A, Caveduck is investing in AI optimization, localization and marketing, with more than half its users already outside Korea.

Caveduck bet that users, not studios, create the most engaging characters, making supply compound without company spend.

Its paid-chat revenue split gave creators a direct income stream — a YouTube-like flywheel that aligns creators with platform growth.

Early global pull proved the bet could travel: 60%+ of users were outside Korea within about 18 months of launch, led by the US and Japan.

It timed falling LLM costs and Gen Z's drift away from games, catching Korean VC money as it rotated out of gaming startups.

Let the community build the supply side: Caveduck's creator economy compounds a character library that pure chatbot apps must spend to match, and it scales across languages.

As of July 27, 2026, Caveduck is scaling: after its ₩4.3B Series A in April 2026 it is spending on AI capability, localization and overseas marketing, with 67% of users outside Korea and more than 110,000 user-created characters. The sector is a tailwind — Korean venture funds are rotating from games into AI character chat, and Kona, a game-focused investor, co-invested explicitly because of the creator-fandom dynamic and falling LLM costs. Sector-level risks remain: copyright litigation against rival Zeta and tightening overseas rules on minors using companion services.
