Sahra‑Josephine Hjorth, founder, AI operator and investor
I advise CEOs and boards on AI strategy, invest in what comes next, and write about where the technology is taking us.
Danish AI founder, investor and advisor. I help executives decide which AI bets to make, invest in early-stage AI companies, and write essays on AI, markets and power.
Where I work
My work sits between technical capability and what happens when that capability meets the real world.
Build
I have spent more than a decade building AI products and technology companies across machine learning, NLP, generative AI and agentic systems.
Evaluate
I work with the human layer of AI: training data, evaluation, model behavior, fine-tuning, quality systems and the judgments that determine whether an intelligent system is actually useful.
Transform
I advise companies and executives on what AI changes beyond the model itself: products, operating models, organizational design, market positioning and where new technology creates real business advantage.
Selected work
Companies, systems and institutions. I have built companies, designed AI systems, advised leaders and worked across markets in Europe, Latin America and the United States.

A broader question
I am interested in AI because of what the technology can do. I am equally interested in what happens around it.
- Who makes the decisions.
- What gets measured.
- What gets rewarded.
- Which business models survive.
- Which institutions lose relevance.
- Where human judgment still matters.
- And who gets to participate in what comes next.
