  • Whif

    Participated · Series A · Aug 2026

    Whif is an interactive content platform that enables users to form relationships with AI characters and generate evolving narratives through conversation, with anyone able to create and share characters. The service emphasizes relationship- and story-driven interactions rather than predetermined question-and-answer responses, positioning users as creators as well as consumers. Launched in mid-2025, Whif achieved rapid growth: paying users average 217 minutes of daily engagement, payment volume grew at an average monthly rate of 110% over nine months, and monthly revenue expanded 1,000-fold within a year. Whif operates in 13 countries and derives roughly 40% of revenue from overseas markets, targeting over 60% by year-end. The company plans to move the product into a multimodal phase—integrating images and video and extending characters into IP like webtoons, videos, and games—and is expanding headcount across development, planning, design, and marketing to support these plans.

Step Lab has expanded into payload technology, building a 4-meter-class, three-stage deployable SAR mesh antenna and developing an AI-based zoom optical module for space domain awareness through Korea’s Scale-up TIPS program. The company has also developed full small-satellite systems-integration capability via its DaejeonSAT-1 work, which will carry a selfie camera to confirm on-orbit status. With the recent Series A, Step Lab plans to scale mass production of its flight-proven mechanisms and accelerate global commercialization.
