Ask HN: How to sell 'data science consultancy' service?

Hi HN, I'm struggling with the following: many companies can benefit from data science/AI/ML to optimize their processes, profit, costs, etc. We are trying to help companies by doing data science projects for them. But we don't know how to find the clients. I assume potentiel clients don't just google for "data science agency" when they have a problem. They may not even realize things can be optimized/automated, or they may not seek the solution in the data science corner. So how do we sell our services? How do we make them find us, and what keywords/phrases should we use? Should we focus our website on very practical concrete examples, or should we keep it all very high level?
