Nash

Most AI startups pick a flat $20/mo tier and get crushed by whale token burn, or switch to pure usage meters and lose users to bill-shock. Nash is a 100% browser-native AI FinOps workbench that simulates 1,000 log-normal agents using Kahneman-Tversky loss aversion and 2-tier self-selection math. Test 18 real LLM routing stacks, parse private CSV logs locally, run a 240-combination Nash grid-search optimizer, and export production TypeScript router middleware.
