Frequently asked questions
What can you help me with?
Above all with the hardest part: figuring out where AI will really save you time or make you money. I look at how things work at your company, work out what to use AI for and how, design the solution and quickly build a prototype you can actually try. Whether it's a website, an app, an AI agent or a whole multi-agent system. You know within days whether it works, not in six months.
How does working together start?
You write me two or three sentences about what you are dealing with, and I get back to you within 24 hours. Together we find the place where AI really helps you, and I build the first working solution. No slides, but a prototype on the table.
What is GEO?
GEO (Generative Engine Optimization) means making sure AI assistants such as ChatGPT, Perplexity or Google AI Overviews know and cite you. I find out what they say about you today and suggest how to improve it.
How does an assistant over company documents work?
The assistant searches your policies, contracts or manuals and answers with a reference to the exact place in the document. If the answer is not in the documents, it says so instead of making something up. You can try it in the Document Q&A demo in the Agent Lab.
