B2B founders can't get a warm intro to a specific GP because their LinkedIn network maps to the wrong fund partners

A B2B founder targeting enterprise security has identified 5 ideal lead investors but discovers that their existing network's connections all map to the same 2-3 generalist partners at those firms, not the partner who actually covers security infrastructure. So what? Cold outreach to the right partner converts at under 2%, while warm intros convert at 30-40%. So what? The founder ends up taking the warm intro to the generalist partner, who takes the meeting out of courtesy but has no conviction in the space and passes after two weeks of diligence. So what? That fund is now 'burned' — the founder can't re-approach the security-focused partner at the same firm because internal CRM systems flag the company as already reviewed and passed. So what? The founder has permanently lost access to one of their top-5 target investors through a routing error they didn't even know they were making. So what? They end up raising from a less aligned investor who doesn't have enterprise security portfolio companies, which means no customer intros, no domain-specific board advice, and worse signaling for Series A. This problem persists structurally because VC firms don't publish which partner covers which vertical, partner coverage areas shift quarterly based on internal fund strategy, and there is no public directory mapping GPs to their actual current investment theses.
