AI ADOPTION IS NOW THE CLEAREST DIVIDING LINE IN STARTUP ECONOMICS

40% of companies heavily using AI say inflation actually _helped_ their business this year… only 12% of non-AI adopters say the same.

Read Mercury's new report to explore: * The 31-point confidence gap between heavy AI adopters and everyone else * What startups spend on AI each month * What junior hiring looks like at AI-forward companies and beyond

Great investors have answers for science questions because they sit on boards and invest in a lot of companies. They can just inform founders what will work and what won't work. Other areas, such as culture, mission, and strategy, should be the founder's domain and no one else's business.

COMPOUNDED MASTERY

Compounded mastery, where founders possess deep domain expertise prior to starting their companies, is becoming essential as AI makes software development more accessible. This expertise, built over time through trust, networks, and recognition, cannot be replicated by AI or bought with capital. In a future dominated by AI content, only founders with established mastery and trust will thrive.
