What PostPrime does
PostPrime株式会社 is a Tokyo-headquartered, Tokyo Stock Exchange-listed (tyo:198A) social media platform focused on investment content and community. It connects professional investors, financial analysts, and traders — acting as content creators — with Japanese retail investors, offering them access to market analysis across five specialized channels: US stocks, Japanese stocks, commodities (gold, crude oil, natural gas), cryptocurrencies, and a beginner/financial-planner-led education channel. Each weekday channel runs scheduled LIVE programming (between 20:30 and 22:25 JST), supplementing live video with on-demand posts, audio, and images. The company was founded in 2022 by Dan Takahashi and operates with 11-50 employees.
The product surface spans the core PostPrime platform, the Prime membership subscription stack (four tiers — Platinum ¥5,850, Gold ¥3,600, Silver ¥1,650, Green ¥920 per month — plus Prime Plus with a 2-week trial and 15% annual discount), IZANAVI (an AI-powered chart-pattern detection tool trained on 30 years of historical market data and offering 60+ pattern signals, gated to Platinum), a real-time retail-investor market-sentiment voting feature, and a demo/virtual trading environment supplied through group company TakaTrade. Creator monetization operates through subscription gating, individual post purchases (e.g., ¥500 per premium post), creator tipping ("ありがとう"), and a badge/level system that ties earnings to engagement metrics.
The business model is a consumer/creator subscription platform plus ancillary revenue from per-post tipping and an affiliate/referral relationship with moomoo Securities. Distribution is primarily digital self-serve (web and mobile app), with creator-driven acquisition through YouTube, X (Twitter), and Note as second-channel funnels. Operating geographies include Japan as the core market and US-market coverage via the dedicated US Stocks channel. No funding rounds or financial results are disclosed in available sources.
