Touchmark

Touchmark is solving AI pricing - instead of AI being priced per token regardless of quality, Touchmark prices it by the quality, efficiency, and value of the output, so spend is fair, predictable, and tied to what you actually get. Applications emit the events they already produce (model outputs, tool calls, code diffs) with a base price, and Touchmark's out-of-band judge returns a quality-adjusted fair price for each event on a separate valuation stream. A Y Combinator Summer 2026 company founded by Ilia Bolgov and Roman Yanushevskyi in San Francisco; the TypeScript SDK (@touchmark/sdk) is in private beta.

Touchmark publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Pricing, Billing, and Monetization.

Touchmark’s developer surface includes documentation, API reference, getting-started guide, authentication, and 18 more developer resources.
