First touch. Last touch. Every change: captured automatically in your CRM.

PrevVal is a HubSpot marketplace app that automatically captures property changes across your CRM. When a property changes, PrevVal writes the old value to a destination property you choose — instantly, automatically, and permanently. No workflows, no code. Just install, add a mapping, and it runs itself.

You add a mapping inside the PrevVal app — select which property to track, choose a tracking mode, and pick where to store the result. From that point forward, every time the source property changes in HubSpot, PrevVal captures the value and writes it to your destination property. Typically within a minute of the change.

Ignore Blank Values — writes the previous value only when it was not empty. The default and best starting point for most properties like deal stage, owner, or close date.

Include Blank Values — always writes the previous value, even when it was blank. Use this when deliberately clearing a field is itself a meaningful event worth recording.

Preserve Last Known — finds the last truly different non-blank value. It skips blanks, cleared values, and values that match the current value. So if a deal is currently $10,000 and the history shows "", $10,000, "", $5,000 — it skips the blanks and the duplicate $10,000 and writes $5,000. Best for amount fields and anything that fluctuates or gets temporarily wiped.

First & Last Touch — stores two values simultaneously using two destination properties. First Touch locks in the very first value ever and is never overwritten. Last Touch updates on every change. Best for UTM source, lead source, and lifecycle stage origin tracking.

First & Last Touch is a premium mode that captures two values at once using two destination properties. First Touch is written the very first time a value is detected and is never overwritten — giving you a permanent record of the origin. Last Touch updates on every change, always holding the value right before the most recent one. Use it for UTM source tracking, lead source attribution, lifecycle stage origin, or any case where knowing where something started is as important as knowing what it was last.

PrevVal works with Contacts, Companies, Deals, Tickets, and Custom Objects. You can track any standard or custom text, number, date, or dropdown property. If HubSpot has a history of it, PrevVal can track it.

No. PrevVal runs independently — no workflow actions, no custom code, no API configuration. Just install from the HubSpot Marketplace, add your first mapping, and you are done. The whole setup takes about 3 minutes.

Backfill reads your existing HubSpot property history and populates previous values for records that already existed before you installed PrevVal. It is optional — PrevVal starts tracking automatically from the moment you add a mapping. Backfill just fills in the past. Available on Professional and above.

The easiest approach is to clone the property you are tracking in HubSpot and rename it. For example, clone dealstage and rename it Previous Deal Stage. All the dropdown options and internal values are already built in. For First & Last Touch you need two destination properties — one for First Touch and one for Last Touch. A single-line text property works for any source type if you just want the raw value.

No. The only properties PrevVal ever writes to are the ones you set up as destinations in your mappings. Every other property in your portal is untouched. Your existing data is completely safe.

Yes — that is the whole point. Because PrevVal writes to a native HubSpot property, every value it captures is immediately available in reports, lists, workflows, and views. Filter deals where previous stage was Contract Sent. Build a report on contacts where first touch source is google-cpc. Segment by previous owner. It all works natively without any extra configuration.

The event limit is the maximum number of property changes PrevVal can receive within a 60-second window. If that limit is exceeded, the entire batch is dropped for that window — PrevVal does not process partials. On paid plans, those events are deferred to the backfill queue and processed later. On the Free plan there is no backfill, so any events over the limit are dropped entirely.

Free — 50 events / 60 seconds (over limit = dropped)
Professional — 500 events / 60 seconds (over limit = deferred to backfill)
Enterprise — 1,000 events / 60 seconds (over limit = deferred to backfill)

Normal day-to-day CRM usage will never hit this limit. If you are regularly exceeding your plan limit it is most likely a bulk operation — reach out and we can help.
