AI Startup Costs: My $5,756 Credit Card Bill, Before the Big Bills
I walk through my September 2026 credit-card spending while building NexusTrade: $5,756.45 in total, including $2,130.72 for Massive.com market data, $317.79 for OpenRouter, and separate OpenAI, DeepSeek and MotherDuck charges. The receipt also includes flights, everyday spending and a few payments I cannot confidently identify.
The credit-card total excludes major monthly bills. The animated estimates show $2,500 rent, $6,000 mortgage, a $300 car note and roughly $1,000 in other bills, totaling about $9,800 outside the card statement. This is my personal spending breakdown, not a universal startup budget.
