# B2B Sales Tech Stack: Old School vs. New School Tool Swaps

> A list of modern replacements for legacy B2B sales and GTM tools

This reference list maps out 10 common sales tool categories, showing which legacy platforms modern B2B teams are actively replacing with newer alternatives. Sourced from observations across YC startups and enterprise sales teams, it highlights modern tooling trends favoring automation, RevOps, and GTM engineering over brute-force outbound.

• TAM sourcing: ZoomInfo → DiscoLike

• DM Campaigns: Sales Nav → HeyReach

• Email campaigns: Mail Merge → Instantly

• Global phone coverage: Cognism → BetterContact
