Budgeting for AI in Your Startup

The article estimates that AI-related expenses (subscriptions and usage costs) should represent 10-15% of typical startup R&D budgets today, based on a model accounting for engineer salaries (~$200k), AI tool subscriptions (~$18k annually), and incremental AI usage costs (~$12k annually). The author acknowledges significant variance depending on AI maturity and notes that smaller AI-native companies will likely have much higher AI spending ratios.
