A sample b2b org chart for a medium-sized B2B product company is a good place to start. Your company may be much smaller, but that's fine. You most likely have a good idea of where the flaws are. From there, it's simply a matter of ensuring that your new positions are assigned to the appropriate departments and that proper roles are added beneath them. You are already halfway there if you have a marketing team. However, all of this may be easier said than done for new roles with a strong digital orientation. This b2b org chart could also represent a company with a marketing director reporting directly to the President, CEO, or owner (s).
