HubSpot remembers that a property changed. PrevVal remembers what it was.

Every time a property updates in HubSpot, a deal stage moves, an owner changes, an amount gets revised, the previous value is gone. No native way to recover it. No audit trail. No visibility into what changed or from what.

PrevVal fixes that gap permanently.

Install it, add a mapping, and PrevVal automatically captures the previous value of any property the moment it changes, writing it directly into a destination property of your choice. No workflows to build. No custom code. No maintenance. It just runs.

Four tracking modes: one for every use case:

• Ignore Blank Values — writes the previous value only when it was not empty. The right default for most properties.

• Include Blank Values — always writes, even when the previous value was blank. For audit trails where clearing a field matters.

• Preserve Last Known — skips blanks and duplicates, finds the last truly different value. Best for amount fields that fluctuate.

• First & Last Touch — stores two values simultaneously. First Touch locks in the origin forever and is never overwritten. Last Touch updates on every change. Perfect for UTM source, lead source, and lifecycle stage attribution.

The problems it solves:

• Deals discounted before close with no record of the original amount

• Reps reassigned without knowing who previously owned the record

• Pipeline stages moving backwards with no way to report on regression

• Close dates slipping repeatedly with nothing to show how many times a deal was pushed

• UTM source overwritten, killing true first-touch attribution

• Contacts bouncing between lifecycle stages with no history of the journey

Once a mapping is set up, every future change is captured automatically. Use the data anywhere in HubSpot, reports, lists, workflows, or custom dashboards.

Every value lives in a real HubSpot property, not a silo.
