Sahra-Josephine Hjorth
I build AI systems, companies, and arguments about where the technology is taking us.
Danish AI founder, operator, investor and advisor working across agentic AI, human data, model evaluation, enterprise transformation and the changing relationship between technology, markets and human judgment.
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.
Writing
Ideas are part of the work.
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
- 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.
That is the thread connecting the companies I build, the organizations I advise, the investments I make and the things I write.
