Christian Gruber

I build AI products people actually use. Strategy, product, execution. I've founded companies around it, advise others, and invest in founders doing the same.

Founders and product teams building AI-native products. I also advise companies bringing AI into their products and operations for the first time.

Four formats: a single 60-min session (€375), light-touch monthly (€1K), weekly cadence (€3K), or near-embedded for full-sprint mode (€6K). Paid upfront, no contracts.

I build and ship, not advise from the sidelines. I run an AI agency, invest in AI startups, and have been building AI products for years. Most consultants stopped at strategy. I kept going to production.

My AI-native agency. We design, build, and ship AI products end to end — from strategy to production.

Telecom, media, gaming, health, enterprise SaaS, and cloud infrastructure — among others. The principles of AI product design are largely industry-agnostic. I focus on wherever experience quality and retention matter.

Selectively. I'm open to the right leadership role at the right company. Reach out to discuss.

AI-first products where experience design is the moat. Early stage, founder-led, opinionated about craft.

Berlin. I work with teams globally.
