Value7/10
7 - free tier and $199/yr Starter are competitive; Pro at $99/mo is pricey for retail but cheap vs. institutional alternatives.
Ease of use8/10
8 - clean UI, fast onboarding, screener accessible immediately; no steep learning curve for the core workflow.
Ecosystem5/10
5 - API available on Pro but native integrations are limited; no direct brokerage or portfolio-app connectors documented.

What it really is

AltIndex — AI-powered alternative data platform for retail stock investors.

Our take

AltIndex aggregates non-traditional signals — app downloads, job postings, web traffic, social media sentiment, and employee satisfaction scores — to surface stock momentum before it shows up in earnings reports. The DB listed entry price as null; paid plans actually start at $29/mo (Starter) with a free tier available. It pitches a claimed 75–80% AI pick win rate, which warrants independent verification, but the breadth of alternative data sources is genuinely differentiated for retail investors.

Why we rate it

Delivers a genuine alternative-data workflow that was previously only accessible to institutional quants, at a consumer price point. The free tier removes friction for first-time users.

The catch

The 75–80% claimed win rate is marketing-grade and unaudited; performance in choppy markets is unclear. Pro tier at $99/mo is steep for casual investors, and API access (a key feature) is gated behind the highest tier.

Best for
Self-directed swing traders hunting early momentum signals
Retail investors wanting alternative data without Bloomberg costs
Portfolio managers tracking app-download or hiring trends pre-earnings
Not good for
Passive index investors who don't need stock-picking signals
Institutional quants needing raw data feeds and SLA guarantees
Crypto-only traders (stock focus dominates the platform)
Friction report
Time to value
Fast: free account signup is instant; AI stock scores and screener are accessible within minutes of onboarding.
Scale breakpoint
10-stock portfolio cap on Starter forces an upgrade to Pro; API access only unlocks at $99/mo, limiting programmatic use on lower tiers.
Walled garden
Moderate: data exports and API access exist on Pro, but the AI scoring logic is proprietary and the platform's signals don't port easily to third-party tools.
