Integration-led pitches should map to the systems that already run customer, agent, borrower, claims, title, servicing, finance, or collections workflows. Strong wedge products reduce manual work, improve data quality, lower risk, or make existing cloud and CRM investments more productive.
Displacement pitches need evidence that the current tool creates measurable friction. Adjacent or workflow-specific integrations are usually easier than replacing a core system in a regulated public-company environment.
