Event-sourced vs event-influenced pipeline, explained
A one-question test for which opportunities your event created and which it only touched, and how vendors and CRMs word the two terms.
By CordiallyPublished · 4 min read
The short answer
Event-sourced pipeline is the opportunities your event created. Event-influenced pipeline is the opportunities the event touched or sped up. A deal that was open before the event can be influenced but never sourced. Vendors and CRMs word both terms differently, so write your rule down before you report either number.
What is the difference between event-sourced and event-influenced pipeline?
Event-sourced pipeline is the opportunities your event created. Event-influenced pipeline is the opportunities the event touched or sped up. The event is where the first kind began and a step along the way for the second.
Definition
The creation test is one question asked of every opportunity: did its record exist before the event? If it did, the opportunity is influenced at most. If it did not, and the event produced the first meeting, it can be sourced.
A deal that was open before the event can be influenced. It cannot be sourced.
How do vendors and CRMs define the two terms?
No neutral standard exists. Vendelux, an event-intelligence vendor, states the sourced half plainly:
“Event-sourced means the event created the opportunity, no prior pipeline existed.”
| Source | Sourced | Influenced |
|---|---|---|
| Vendelux (events) | "the event created the opportunity" | "the event appears somewhere in the multi-touch attribution path for an opportunity" |
| Metadata (marketing in general) | "any deal that started directly from a marketing activity" | "any deal where marketing had a touchpoint somewhere in the buyer’s journey" |
| Salesforce | The page never says "sourced". Its default model gives 100% influence to the campaign in the Primary Campaign Source field | Models that find campaign members "who are also assigned a contact role on an open opportunity" |
| HubSpot | The page never says "sourced". Its Deal create option counts deals the campaign's assets helped generate | "the deal must be associated with at least one influenced contact" |
In both CRMs, the field or contact link that your reports read decides what a report calls sourced or influenced. Check which one that is before you trust a label.
What does each number tell you about your event?
Sourced pipeline answers whether the event opened doors that were shut. Influenced pipeline answers whether it helped deals already in play. They measure different jobs, so a low number in one says nothing about the other.
Expect the split to follow the guest list. A customer summit seats accounts that already have open deals or renewals, so most of its pipeline will be influenced. A regional dinner for accounts you have never met can produce sourced pipeline. Judge each event by the job it was built for, and report the other line without apology.
Which number do you report to finance?
Report both on separate lines and lead with sourced. Vendelux gives the reason:
“Event-influenced is always the bigger number; event-sourced is the more conservative and more defensible number.”
Do not add the two. An opportunity the event created also has the event in its path, so the sum counts it twice.
How do you apply the creation test to an event you host?
- Freeze the guest and account list before invitations go out.
- Pull the opportunities at those accounts and sort them by the date each record was created.
- Put opportunities created inside your window, with a first meeting at the event, in sourced.
- Put opportunities that were already open in influenced, listed with the deal.
- Publish the rule and the window beside the number.
Write the rule down before the event, not after the results.
The window and the full method are in how to prove event ROI at account level. Why a CRM report may show nothing at all is in why your CRM shows no event influence.
Frequently asked questions
Can an event-sourced deal also count as event-influenced?
Under Vendelux's definition of influenced, yes, because an opportunity the event created also has the event in its path. That overlap is why the two numbers should not be added. Report sourced first, show influenced beside it, and say that influenced includes the sourced deals.
Which number is larger?
Event-influenced. Vendelux says it is always the bigger number, and that sourced is the more conservative and more defensible one. Finance trusts the figure it can trace to an opportunity record created after the event.
What counts as a new opportunity?
The sources we read don't say. A workable rule is an opportunity record created after the event date, inside your window, at an account that attended, with a first meeting at the event. Decide in advance how you treat a revived closed-lost deal and disclose the choice.
Does Salesforce or HubSpot report sourced pipeline?
Not under that name on the campaign pages we read. Salesforce credits a campaign through the Primary Campaign Source field or through contact roles. HubSpot uses influenced contacts and a Deal create option. Find which field or association your report reads before you quote it.
What window should I use?
Set it before the event and disclose it. Vendelux recommends reporting event-sourced pipeline at 180 days, but we found no neutral benchmark behind that figure. Pick a window you can defend, and apply it to every event in the year.
