What STiLy Japan does

STiLy Japan (株式会社スタイリィ) is a Tokyo-based Japanese fintech that operates propro (プロプロ), a self-serve long-term equity investment analysis platform aimed at Japanese retail investors focused on fundamental, long-horizon stock selection. The web platform and mobile apps let individual users input a sales growth rate assumption and receive computed target stock prices, buy/sell limit orders, marginal profit rate projections, net cash ratio screens, and a 15-year revenue projection for any of roughly 4,000 Japanese listed companies, with daily recalculation across the listed universe by 7 PM. The core analytical technology centers on a DCF-based valuation engine with a proprietary marginal profit rate auto-calculation derived from historical financial data, a "stock price weaving" framework that compares market-implied growth against user assumptions, and a "Priority Score" star-based analyzability rating; in February 2026 the platform added a Google Gemini generative AI layer for business summaries, SWOT analysis, and "buy-worthy performance scenarios," scoped to IR sources to limit hallucination.

The business model is consumer-direct and product-led: free trial with email-only magic-link authentication, a single-purchase pay-as-you-go tier at 500 yen per company per month (capped at three companies), and an unlimited-company monthly/annual subscription supported by discount coupons that now apply to both single purchases and subscriptions (as of 2025). The company monetizes entirely from individual long-term investors analyzing Japanese equities, with no enterprise tier, B2B contracts, or institutional accounts. Acquisition is content-first via a YouTube series hosted by founder Nakamura (a former fund manager), an investment blog, a LINE official account for push notifications, and earned media coverage in DIAMOND ONLINE. The company was founded circa 2015 (per firmographic record), closed a single disclosed JAFCO financing of $1.34M in May 2017, and continues to operate with a 1-10 person cross-functional team covering PM, engineering (server-side and front-end), UX, testing, and user gathering.

Direct peers

• Kabutan (株探): Leading Japanese stock information and analysis portal serving retail investors with financial data, news, and screening tools. Directly comparable to propro as both target Japanese retail investors with fundamental-analysis-oriented equity data and analysis features.
• Minkabu (みんかぶ): Japanese retail-investor platform offering stock quotes, analyst forecasts, and crowd-sourced sentiment. Highly comparable to propro in serving Japanese retail investors with fundamental and sentiment analysis tools.
• TradingView: Global charting and technical-analysis platform with significant Japanese retail-investor adoption. Comparable to propro in providing individual investors with screeners, watchlists, and analysis tooling, though TradingView emphasizes chart-based technical analysis versus propro's DCF-based fundamental approach.

Broad incumbents

• Yahoo! Finance Japan: Major Japanese financial information portal providing quotes, news, screening, and basic analytics for retail investors. Broader incumbent offering that overlaps with propro on stock-data and screening but lacks propro's DCF-based valuation methodology.
• WealthNavi: Leading Japanese robo-advisor offering automated, algorithm-driven portfolio management for retail investors. Comparable as it addresses the same Japanese retail-investor wealth-building need that propro targets, though WealthNavi is fully discretionary while propro is a DIY analysis tool.
• THEO (Money Design): Japanese robo-advisor platform offering automated long-term investing for retail clients. Comparable to propro in targeting long-term, fundamentals-aware Japanese retail investors, but as a managed robo-advisor rather than a self-serve analysis tool.
• Money Forward: Major Japanese personal finance and SaaS fintech platform offering household-account, business-account, and HR/payroll cloud software. Adjacent incumbent—same Japanese fintech category and overlapping retail-investor persona, but focused on personal-finance management rather than equity valuation.
• SBI Securities: Largest Japanese online brokerage offering trading tools, research, and information for retail investors. Comparable in serving Japanese retail investors with analysis and decision-support features, but as a full-service brokerage rather than a stand-alone analysis product.
• Rakuten Securities: Major Japanese online brokerage with bundled research, screening, and market-data tools. Overlaps with propro's screening and analysis features, but is part of a much broader brokerage offering and primarily chart-trading oriented.

Emerging players

• Zaim: Japanese household-account and personal-finance app with a large retail user base. Tangentially comparable as a Japan-focused consumer fintech serving retail financial decision-making, though its focus is budgeting rather than equity valuation.
