MarginDash's answer
Most AI observability tools track what your API calls cost. MarginDash tracks whether your customers are profitable. It connects AI costs to actual Stripe revenue and shows realized margin per customer — the number that determines your pricing and where to cut costs.
MarginDash's answer
Three reasons: it connects cost to revenue (competitors only show cost), the cost simulator ranks alternative models by intelligence per dollar so you know quality won't drop, and the SDK never touches your prompts or responses — just metadata.
MarginDash's answer
SaaS founders and engineering teams that resell AI API features to their customers and need to know which customers are profitable after AI costs.
