Who we are
IndieStats is a focused data intelligence product for indie game developers, publishers, investors, and analysts. It turns public Steam and itch.io signals into estimated sales ranges, growth curves, category trends, and publisher profiles.
How sales are estimated
The model starts from the classic Boxleiter idea that review counts correlate with sales, then adjusts for genre and price behavior to produce a point estimate and confidence range.
Output: point estimate + confidence range + model version
- Review count comes from public Steam review data.
- Genre correction reflects different review-to-sales behavior by category.
- Price factor accounts for purchase and review willingness across price bands.
- Confidence range shows how stable the model fit is for the sample.
Important: every sales number is an estimate, not official data. It is for reference only and should not be the sole basis for investment, publishing, or contract decisions.
Data sources and updates
- We use public page data: reviews, prices, tags, review rates, and release dates.
- Scraping frequency is controlled and failed fetches keep prior values with delay context.
- Each data point carries a timestamp and method context.
- Rankings update daily; category notes are written for weekly reading.
Developer calibration
Developers can verify ownership and submit real sales or wishlist data. Approved submissions improve the calibration set and can be kept anonymous.
Limitations
- Free-to-play, Early Access, bundles, and cross-platform sales can widen error bands.
- Review incentives or unusual review behavior can distort estimates.
- New launches have fewer signals, so their ranges are wider.
- When developer-reported data conflicts with estimates, calibration takes priority.
Neutrality
Rankings are sorted by objective metrics. Sponsorship or affiliate relationships, if any, are disclosed and do not influence ranking order.
API and export
Pro members can export CSV / PNG data. Publisher and analyst APIs are planned. See Pro pricing.
