Seeking ABM Strategies for Startups in Sales Outreach

Hello everyone, I am an engineer-turned-salesperson working at a startup called Tapper. I'm building out their outbound engine while also doing sales work. I am new to Clay, and I would love to learn more - specifically, I would want to know more about ABM strategies. For example, if I know that there is a list of 50-100 companies that fit our ICP, how do I build campaigns around the 3-5 key people who might be champions for what we do and suggest us to the person in charge of making the buying decision. I'm not sure if I should post my LinkedIn here, but please DM me and I'll send it to you.
