§ Agent · Fullstory

The Fullstory data agent that acts the way you would.

It keeps an eye on your Fullstory session and event data alongside your revenue and account health data, on a schedule you set or whenever fresh data lands. When usage patterns shift in ways that predict churn or expansion, it tells you, or handles it the way you'd want.

⚠️ Trial activation down 31%, $42k pipeline at risk from drop-off at step 3

Your onboarding funnel's step-3 completion rate fell from 64% to 44% over the last 9 days. Sessions are starting fine and step 2 holds steady, but the data-connection step is losing users. The regression correlates with the June 9 deploy. Trials from the enterprise segment are converting to paid at half the baseline rate this cohort.

How an agent works

An agent watches one thing and acts on it. Not a workflow, just a standing watch that usually does nothing and acts the moment it should.

◄ repeats on the schedule you set ►

You stay in control

An agent does what you'd do, and only what you've authorized.

The same trusted numbers

It acts on the same governed metrics as your dashboards, and every action is logged and traceable.

You approve anything that writes

It alerts and recommends on its own; anything that changes data is yours to approve.

Try it on a test channel first

Point a new agent at a throwaway channel and watch its judgment before it touches anything real.

No false alarms

It remembers what it already flagged and waits before acting again, so it won't alert you about the same thing twice.

What you can put an agent on

ActivationACROSS YOUR SOURCES

Tie session behavior to trial conversion and expansion revenue

It joins your Fullstory event and session data to your billing and CRM, so you see which usage patterns actually produce conversions and expansions, not just pageviews and session counts. When an onboarding flow that used to activate trials stops producing paying customers, you find out before the cohort is lost.

Funnel

Catch a funnel regression before it compounds

When a step in your critical flow drops below its baseline, it tells you which step broke, which user segments are affected, and what changed. You find out the day the conversion shifts, not two sprints later when someone notices the weekly number is off.

EventPageviewSession
Engagement

Spot the usage pattern that predicts churn

It watches session frequency, depth, and feature adoption by account over time. When an account's engagement decays below the pattern that historically precedes churn, it flags the account, the features they stopped using, and how much ARR is at risk, so your CS team can intervene before the renewal conversation.

SessionUserEvent
Custom

Run any Python it needs to get the job done

Beyond alerts and write-backs, an agent can run arbitrary Python, so it can do whatever the task actually requires: call an API, kick off a job, reshape the data, or wire into your own tooling. The action space is yours to define.

Why not just build it yourself?

You could rig one of these with a cron job and a Slack webhook in an afternoon. The watching is the easy part. Here's what you'd own forever, and don't, here:

  • The cross-source join: not one tool's data, but it reconciled against the rest of your stack
  • A trusted, consistent metric: the same number your dashboards use
  • The investigation into why, when something fires
  • A full audit trail of everything it did
  • The upkeep, when the schema drifts or the script breaks at 2am

The data it works from

Every Fullstory object, modeled and query-ready the moment you connect.

§ FAQ

Common questions

You set the schedule, and it also re-checks whenever fresh Fullstory data lands. Each agent watches the one thing you point it at, nothing else.
It alerts and recommends on its own. Anything that writes, whether to a tool, your warehouse, or a customer, is yours to approve. You can also point a new agent at a test channel first and watch its judgment before it touches anything real.
When something fires, it can hand off to Fi to investigate, drilling into the data it has across your connected sources to find what's behind the move, and showing its work.
Those analyze sessions inside Fullstory, when you go look. This watches continuously, joins session behavior to the revenue and account data Fullstory never sees, and hands off to Fi to investigate why an onboarding funnel stopped converting to paid, so you find out before the cohort churns, not after.
