Slowio
40+ years of stock fundamentals and ratios for 30,000+ companies, free to start.
Slowio is a fundamental-analysis platform for stocks, ETFs and portfolios: more than 40 years of financial statements and ratios for 30,000+ companies across 20+ markets, a value screener, and correlation/risk tools for a portfolio. It explicitly shows facts rather than advice — it never says what to buy or sell, doesn't hold money, place trades or connect to a broker. Data is end-of-day and refreshed daily, not real-time, and there's no futures, FX, crypto or intraday coverage. The Free plan has no time limit and a monthly allowance good for studying a handful of companies; Premium and Advanced raise that allowance and can be cancelled anytime.

- +40+ years of restated financials for 30,000+ companies — a 1990 ratio compares cleanly with today's.
