Definitely, go for a collection of tools as Parth mentioned. Could be Apollo, Lusha, ZoomInfo, etc. Paid plan on 1 (maybe your favorite one) and free plans on the rest has worked me ( I work at an early stage startup)
For the lack of profiles on Apollo, a combination of profiles in personas you create could work. In my experience, different people at different stages of a company are responsible for similar kind of work/could be a decision maker who buys from you.
