AI Budget Allocation Framework for Startups
Tomasz Tunguz analyzes how much startups should allocate to AI as a percentage of R&D spending, proposing a framework that accounts for engineer salaries, AI tool subscriptions, and additional compute costs. Based on practical experience, he estimates typical startups should budget 10-15% of R&D expenses for AI, with higher ratios for AI-native companies.
