AI companies fly blind on inference margin.

We track cost per token obsessively. We negotiate rates. We A/B test prompts. And then we ship the product and forget to ask the only question that determines whether the business works: is the token actually profitable?

Gross margin is a settled idea in every other industry. SaaS companies know their margin per seat. Marketplaces know their take rate. Lenders know their net interest margin. AI companies, somehow, know their blended cost and call it done.

That blended number quietly averages your profitable segments with your unprofitable ones. Margin leaks accumulate. Nobody sees them until the board meeting.

InfFyn exists to make profit-per-token a standard — the way gross margin is standard everywhere else. We're the financial controller for AI inference.
