Pre seed - doing whats right vs what investors ask for (I will not promote)

In the process of preparing pre seed raise. We have paying customers and over the last 8 months we have been redeveloping our product with them. Although we have been omboarding a few more customers, I don't think we have product market fit yet. People helping me with the raise suggest to go very heavy on the sales through this funding. My startegy for the pre seed was to cover 24 months of runway and get a sales person and a fractional CMO to generate leads and grow revenue whilst we refine the product. I'm worried scaling too quickly will just put us in the same category as the companies we are up against were customers are paying (its b2b) but the product is not used because unfit for the users (staff). Any return on experience to share? How best I should approach this? I think the people advising me are not wrong and their advise is tailored to "how to raise money" because tjs rhe objective. But part of me is hoping to raise money from the right people so the product development remains at the heart of the company.
