Prevent runaway LLM token costs with per-feature budgets & alerts

Executive Summary

Modern product teams at roughly 2M SMBs and startups embedding LLMs into features are increasingly exposed to runaway token bills and surprise spikes because major providers like OpenAI, Anthropic, and Cohere charge per token and usage can vary dramatically across endpoints. Many of these teams lack per-feature budget controls or fine-grained cost attribution, so token spend becomes a material operational cost and a finance/engineering coordination headache. You could build a developer-focused platform that attributes token usage to specific features and endpoints, lets teams set per-feature budgets and predictive alerts, and optionally enforces soft or hard caps with automatic fallbacks — delivered through lightweight SDKs, API-gateway integrations, and hooks into observability/ML-monitoring pipelines. The timing is favorable: a $6.0B addressable market (2M SMBs × $3K ACV), a market score of 92/100 and revenue potential 82/100 indicate both scale and willingness to pay, and recent convergence of telemetry and ML monitoring finally makes accurate per-endpoint cost attribution practical. To stand out in a medium-competition landscape you’ll need precise attribution, multi-model support, low-friction developer ergonomics, and predictive cost forecasting plus pre-release cost simulation and auditable controls that appeal to both engineering and finance. The strength of this idea is immediate ROI for teams already spending thousands monthly on tokens; the main challenges are integrating diverse model APIs without adding latency, handling enterprise security/PII concerns, and driving the behavioral change to enforce budgets rather than ignore alerts.
