Projects

An opinionated German learning app: one path, not a menu. Sprache builds a personalized 100-day curriculum and walks you through a single daily session — lessons, flashcards, podcasts, pronunciation and speaking — all around the same words. (“Sprache” = German for “language”.)

Product analytics and unit economics for people who don't live in spreadsheets. Describe a product — an idea or a live business — and StartupMetrics computes every SaaS metric, projects 12 months out, and tells you which levers to pull to reach profit.

AI contract review for German small businesses. Klarsel flags every risky clause in plain German, scores the contract 0–100, and drafts the email to negotiate it — so you understand any contract in 30 seconds.

The workspace for vibe coding — a local-first markdown desktop app for the context documents that drive AI-assisted development.

Short links with real attribution. Shortifi replaces bit.ly and three spreadsheets with one workspace — branded short codes, custom domains, UTM hygiene, and click analytics that match what your CRM sees — built for marketing teams that actually have to defend the numbers.
