Three different ways to show off your client list, depending on what you want to emphasize:
- Page of logos to show that they include the biggest names in the industry (here is how to design one)
- Map with dots to show that they are scattered around the globe
- Bar chart with sales number ranking to show how much you sold them (if you can share this information)
Mixing them up might not give the best picture: logos of completely unknown companies, a world map with lots of dots in New York City.
