You have visibility everywhere except here
You see total spend. You don't see which team spent what. Marketing? Engineering? Data Science? Unknown.
Without visibility, nobody owns the problem. Everyone assumes it's someone else's budget.
Bills keep growing. You can't optimize what you can't see. First step: visibility.
The moment we showed teams their individual costs, behavior changed. No mandates needed.

Everything you need to know
Substacker is an AI cost intelligence platform that breaks down your AI spending by team. Unlike provider dashboards that show total spend, we give you team-level attribution - showing exactly which teams spend what on OpenAI, Claude, Gemini, and Azure. One CSV upload, 2 minutes, complete visibility.
Export your usage data from any AI provider (CSV format), upload it to Substacker, and we instantly analyze it. Our algorithm identifies team ownership through API keys, email domains, or team tags in your data. Results show costs by team, model usage, and optimization recommendations - all without storing your raw data.
First analysis is completely free - no credit card required. We're building premium features (real-time dashboards, budget enforcement, automated alerts) that will be available soon. For now, focus on getting your initial team cost breakdown and understanding the value.
The first step to cost control is visibility.
Know which teams are spending. Make informed decisions.
Free. Secure. 2 minutes.
