This year again, Supabase surveyed 2,000+ startup founders to uncover what's powering modern startups: their stacks, their GTM motion, and how they approach AI.
Many things have changed between 2025 and 2026.
My key takeaways:
78% of founders are technical.
Claude Code became the most-named must-have dev tool (31%). VS Code held flat (22%). Cursor dropped to 15%. v0, Bolt, and Windsurf each lost 6-9%. Anthropic models are the most used.
AI-generated code is the median experience. 62% of startups have more than half their codebase written by AI. 41% are at 76-100%. Only 2% are at zero.
Founders still do sales themselves. Personal networks remain the top source of initial paying customers (56%). 67% of respondents have never tried paid acquisition.
Founders are broadcasting less. Social media lost users across every major platform. Conferences emptied out.
Technical complexity is no longer the main challenge. AI ate the hard parts of shipping. What replaced it: burn out, AI-competition fear, runway anxiety.
56% of founders remain optimistic about the future.
