Today I delivered a training session at the Gyeonggi Business and Science Accelerator in Suwon for B2B marketing and sales staff from regional mid-sized companies. We covered everything from B2B marketing strategy to hands-on sales practice, and the last session was the liveliest. How can AI agents be used in the field? As soon as I raised the topic, everyone started sharing their own situations. One person still manages clients by hand. Another said that half of each day goes to reviewing site photos and typing them into Excel. Another said that outsourcing 3D rendering costs a lot every single time.
Everyone had plenty they wanted to automate, but nobody knew where to start. I had one thing to tell them: domain knowledge is the prompt. Someone with 20 years of field experience who knows just a little about AI will produce far better results than someone who knows only AI. They know what needs to be built. The tools are ready. All that’s left is to use them. Thank you to everyone who joined today. I was completely spent by the end of the day. I slept like a log in the taxi and on the train.
