Your Day-3 activation Canvas is still generating opens and clicks at baseline, but product signups from that journey dropped from 310/wk to 183/wk. The gap opened Tuesday when the new welcome variant went live. Segment 'Trial-High-Intent' is 74% of the miss.
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.
An agent does what you'd do, and only what you've authorized.
It acts on the same governed metrics as your dashboards, and every action is logged and traceable.
It alerts and recommends on its own; anything that changes data is yours to approve.
Point a new agent at a throwaway channel and watch its judgment before it touches anything real.
It remembers what it already flagged and waits before acting again, so it won't alert you about the same thing twice.
It reconciles your Braze campaign and journey data against your product usage and revenue, so you see which sends actually move activation, retention, or expansion, not just opens and clicks. When a journey that used to convert stops producing paying users, you find out before the cohort churns, and you can trace the blended CAC back to the lifecycle stage where the funnel broke.
When bounce rates or delivery rates shift on a campaign or channel, it tells you which segments and sends are affected and how many users you're missing. You find out the day it moves, not when the campaign post-mortem reveals half your audience never got the email.
It watches your DAU, new user, and uninstall trends. When growth and engagement diverge (acquiring faster than activating, or DAU dropping while installs hold), it flags the gap with the segments and journeys behind it, so you can trace the problem to the lifecycle stage where users are falling off.
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.
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:
Every Braze object, modeled and query-ready the moment you connect.
It runs on your real Braze workspace (test campaigns, abandoned journeys, segments nobody updated, and all), not a tidy demo.
A message in the channel you choose, with the context and a button to act on it.
A summary in the inbox of the people who need to see it.
A payload to your own systems, to wire the agent into whatever you already run.
A flag written back to your warehouse for everything downstream to pick up.
Kick the question to Fi to investigate the why and propose the fix.
Expose it to your own agents and tools over MCP, and drive it from your stack.
Run it in your own VPC or fully self-hosted. Everything it does is pure SQL and Python you can inspect.
