Leveraging two companies/products at once?

Hi everyone,

first time poster here.

So i work full time for a recruitment marketing firm and recently started part time for a robotics company.

Funnily enough, both roles essentially serve the same function, which is to help deal with the current hiring issues across industries. The first with recruitment marketing strategies, the second with server robots. Industries are also the same more or less(healthcare, food service, retail, senior living)

Anyway, what's the rule book on this. Is it off-putting if I bring up both during conversations with stakeholders. Or is it alright? Sometimes, the stakeholders are also similar as well.
