Hi Markus,I interpret your question to be focused on how to build a customer reference database for internal use and tracking.A word of advice if you also plan to build a publicly viewable customer reference library on your website. Be strategic, targeted, and careful. Posting comes with a risk.
I say this because I am a strategic marketer and some of my most successful marketing campaigns were when I was able to go to a competitor's website and build a target list of my competitor's customers! They were kind enough to list them by industry, contact name, and contact title. Since this was posted publicly, all this data was fair game. I used this data to fuel my Account Based Marketing (ABM) campaign, and they were highly successful. So, watch out because your competitors are watching you, too!Best, Mike Gospe
