without going custom
It sounds like credibility and technical expertise are prime here-with communication / presentation/ performance being a close second
From my understanding
B2B writing you want to be able to capture and convey the opinion/way of being that you’d be representing for the company. Keeping it about the business you work for
you’d want to be able to understand the companies target audience deeply and stay deeply relevant to the case/solution/benefit and prove it for bottom line profitability and connect the target audience with the HOW of why the company your representing will be a solution for their pain points/challenges
In this sense the skill would require research, tactile empathy, and creativity aligned with facts, relevance, and persuasion.
Ultima Only
I think your on the money-Limitless Executive (or BLU) for execution/writing/research/ and Commander for credibility, fact relevance, and communication -couldn’t go wrong adding R.I.C.H (unless it causes to much recon)
For Q/QV2 what I can see theoretically being good for this are
Emperor+ RM, AM/M+RM, Stark, EOG Stage 4, HOM+RM
RM will help with emphatic resonance, persuasive writing, and innovative solutions+connections you will come up with–and a sub with business/mogul savy would keep it on track. HOM really helps with clients/new business in my experience as well.
