Stratosphere.io

Research & Analysis — Freemium

A clean fundamentals platform offering 10+ years of financial data, KPIs, and AI-assisted company analysis.

Deep KPI history

Overview

Stratosphere.io is a fundamentals research platform built for long-term investors who want deep financial history without paying enterprise-software prices. It sits in the research and analysis category, organizing more than a decade of financial data, segment-level KPIs, and analyst estimates into one clean interface. This Stratosphere.io review is aimed at fundamental investors who actually read financial statements, not traders looking for chart signals. It fits intermediate investors who already know what they're looking for in a balance sheet.

The depth of data is the main selling point. Ten-plus years of financial history and segment-level KPIs let you see how a business has actually performed over time instead of relying on a single snapshot. AI features help summarize a company's fundamentals and trends without requiring you to dig through raw filings line by line. The interface stays clean and organized despite all that data, and watchlists, comparison tools, and exportable data support a genuine fundamentals-first research workflow.

The limitations are about scope, not quality. This is a fundamentals-only tool, so there's less real-time focus, meaning it's not built for anyone watching intraday price action or technical setups. If your process depends on charts, momentum, or live quotes, this platform won't cover that side of the work. It's built for research between trades, not during them.

Stratosphere.io covers US and global stocks, built entirely around long-term investing with a manual research workflow and API access for anyone who wants to pull the data into their own systems, though there's no mobile app yet. Pricing starts at Free / $20/mo, with a free trial available to test the deeper data before paying. Skip it if you need real-time technical tools or trade short-term; this isn't built for that. It's a strong fit for intermediate, fundamentals-focused long-term investors who want rich historical data at a fair price.
