Cosmo Gräf
Builder of agentic systems. Founder of Cittasana S.R.L. Munich-based, working internationally.
Profile
I build end-to-end — and got here on a winding road. Trained as a certified auto body technician through Germany's dual apprenticeship system, then industrial machinery, then two years as an insurance advisor at AXA Munich. Founded Cittasana in 2023 — first as a Bhakti yoga practice, today as a small AI-automation studio.
Most of my time goes into Zeus, the agentic OS I designed and built from scratch. It runs my company end-to-end: mail triage, meeting prep, sales pipeline, back-office. Production-grade TypeScript and Next.js, 9 LLM-orchestrated tools, 7 scheduled cron workflows, ~20 active B2B clients.
What ties the road together: curiosity and craftsmanship. The apprenticeship taught me that there's no such thing as a 90% weld — something either holds or it doesn't. I carry that mindset into code, systems, and client work.
Experience
Designed and built Zeus, a production-grade agentic OS in TypeScript + Next.js 16. Run end-to-end client operations for ~20 active B2B accounts across construction, energy consulting, wellness, and coaching. Full-time on Cittasana since April 2026.
- Architected agent runtime: tool registry, persona system, approve/veto tokens, audit log, tier policy, secrets vault, GDPR layer.
- Shipped 9 production tools (mail-triage, meeting-prep, competitor-pitch, briefing-synth, content-atomizer, research-task, task-create, tax-presort, slack-to-task) and 7 launchd cron workflows.
- Stack: TypeScript, Next.js 16, Supabase (Postgres + RLS), Anthropic API, MCP, Vercel, Slack/Gmail/Stripe integrations.
Advised private and commercial clients on multi-line insurance portfolios. Two intense years of regulated-industry domain knowledge — which now shapes how Cittasana approaches finance and compliance work.
Founded Cittasana as a wellness-first brand; later pivoted into the AI-automation studio. Designed customized Bhakti Yoga programs integrating meditation, breathwork, and mindfulness. Built early client base and operational discipline.
Installed and serviced industrial technical equipment. Coordinated parts orders, vendor scheduling, and turnaround timelines.
Precision body repair, welding, and panel installation to OEM standards. Worked with steel, aluminum, and composite materials in collaboration with painters and mechanics.
