I've been at a small technical company (<20) since the beginning of this year where I'm involved in product development and research. We expect to grow a lot this year and add a bunch of new clients to our roster, so some of our new resources include a Chief Marketing Officer (CMO), marketing manager, and a marketing associate. We have 4 marketing people total now.
After planning out a content schedule earlier this year, they launched their first blog posts. Unfortunately, the launch email is now serving as an issue log. Errors range from grammar mistakes to critical arithmetic errors that disprove their main points. Worse, the CMO has been defending "$1mil ROI" even though that clearly isn't a ROI. A few of us have tried verifying some of their numbers, but can't find a single correct one. The marketing manager has politely declined to share drafts, and the CMO has taken to calling people out for vocalizing these issues, so I'm unsure how to fix the damage.
Given the content is about the work I'm contributing to, I want to have this content done well. I'm debating rewriting them myself and taking my drafts to the exec board. Failing that, I'm unsure if staying at this company will benefit my career. I'm not sure how I would explain my work to anyone in the industry right now. The work is top notch, but now there are a lot of misleading and faulty statements attributed to it, from our own company no less.
How do I help a department I'm not in course correct when the C-level exec is beginning to get defensive?
