A 26-year-old software engineer quit his corporate job, moved back in with his parents, and used AI coding assistants to build a LinkedIn content tool that hit $62k MRR in just 90 days.

The story of Cameron Trew and Kleo (kleo.so) illustrates how AI code editors are enabling solo founders to outbuild entire teams.

Key insights:

- Built MVP in 4 weeks using Claude Code vs. estimated 10-12 weeks without AI (60-70% time savings) - Stack: Next.js, Vercel, Neon, Inngest, Clerk - all AI-augmented - Distribution-first: leveraged cofounder's 180k LinkedIn followers, no ads or Product Hunt - 500 beta spots at $59-79/mo sold out in 4 days - $62k MRR by month 3, on track for $300k MRR

The AI-native stack he used: - Claude Code for primary coding - Claude Vision for document analysis - Vercel AI SDK for chat interfaces - PostHog + Langfuse for observability - Deepgram for voice-to-text - Perplexity API for web research

This isn't "AI wrote my code, I went to the beach." It's "AI gave me leverage, I focused on architecture, user empathy, and distribution."

For solo founders, this changes everything. What would have cost $10k/mo in engineer salaries 5 years ago now costs $100 in infrastructure + 1 highly-leveraged founder.
