Efficient Approaches to Identify and Enrich Key Decision Makers Without Traditional Titles in Startups

Hello, community. I’m building a workflow which detects funding and growth signals of companies, scores intent and automatically reaches out with a personalised message to their key decision makers. Now, normally the key decision makers to go for usually have titles “Vp sales” or “head of revops” but nowadays most startups do not associate with these traditional titles. My question - What is the most efficient approach to enriching these key DMs who do not have traditional titles from their respective companies?
