I have had the displeasure of working alongside marketing as a BDR & AE... but, GODDAM there is one person that comes to mind when I think of a "useless marketer".
This person was a marketing manager at one of the startups I worked at in the past. I still do not know what she did for the company. They would come into work at 10am (this is before work from home due to COVID). They would proceed to lecture the BDRs on how they ought to communicate to inbound leads (except we didn't get inbounds EVER). From about 11-2, they would disappear into a WeWork personal meeting room to brainstorm social media & email marketing campaign ideas. I know this because their calendar was available to the whole company. Then they would take an hour long coffee break @ Blue Bottle & finish up some "work" & leave the office at 4pm.
The BDR team never saw an uptick in inbound leads & the BDR manager eventually quit because they CMO made this marketing manager the BDR manager's equivalent. The outbound BDR team were savages & sourced millions of dollars of revenue with no inbound help.
That was my first company and experience with how useless marketing can be.
What is your worst experience with marketing?
