The partnership OS built for indie hackers — by an indie hacker.
Co-founder agreements shouldn't cost $3,000 and three weeks. BuildersScroll is the AI-native partnership OS for indie hackers, solopreneurs, and emerging builders — built in public on Twitter, with Claude Code, by one of them.
The stack indie hackers cobble together is broken.
Stripe Atlas does C-Corp incorporation. Clerky does post-formation cap-table docs. Carta does cap table. DocuSign does generic signing. Harvey AI and Spellbook serve big-firm lawyers. The indie SaaS founders shipping with Claude Code and Cursor in 2026 — forming co-founder partnerships, advisor agreements, and IP splits — fall through every gap.
They pay roughly $3,000 over three to six weeks to stitch the tools together. We replace the stitching with one product: Charter, lifecycle, signing, reputation — for the price of one SaaS subscription.
Charter. Lifecycle. Signing. Reputation.
Free, AI-drafted partnership agreement in 30 minutes. Co-founder pair, advisor, or contractor.
Capital calls, advisor adds, contractor agreements, IP transfers, side letters, dispute resolution, exit. $19/mo per active partnership.
Audit-grade. IP, user-agent, and SHA-256 document hash captured at signature. Certificate of Completion PDF on close.
Every shipped partnership compounds your BuilderScore. A verifiable history of who you've built with.
By an indie hacker, for indie hackers.
I'm Darien. I'm building BuildersScroll daily with Claude Code — sharing every TASKS.md update, every ship report, every customer interview on Twitter. The Charter library, the lifecycle event model, the BuilderScore algorithm — all designed against the friction I felt formalising my own first partnership.
