The Changelog

Everything your team
has tried. In one place.

Log every retention action your team takes — by date, store, tool, and tactic. So Leon never recommends what you've already done, and your team never loses track of what's been tried.

Retention teams try a lot of things.
Most of them get forgotten.

A new cancel flow goes live. A Klaviyo sequence runs for six weeks. A pause offer gets tested and quietly dropped. Three months later, no one can remember what was tried, when, or whether it worked.

The Changelog fixes this. Every action your team takes — logged in one place, tagged by store and tool, visible to everyone. So your retention history never lives only in someone's head.

How it works

Log it once. Everyone benefits.

Log an action in under 30 seconds

Every time your team implements a retention tactic — a new cancel flow, a Klaviyo campaign, a pricing test — log it in the Changelog. Date, store, tool used, retention function, and any notes about the setup. That's it.

Tag by store, tool, and retention function

Each entry is tagged so it's searchable and filterable. Connect it to the store it applies to, the tool you used (Loop, Klaviyo, Recharge, Solvpath, etc.), and the retention function it addresses — onboarding, churn prevention, win-back, pause flows, and more.

Your whole team sees the same history

No more asking 'did we already try this?' No more duplicate work between team members or agencies. The Changelog is shared across everyone with access to the store — one source of truth for what has been done.

Leon reads it before every recommendation

Before Leon generates any recommendation, he checks your Changelog. If you've already tried a tactic, he won't suggest it again. Every recommendation you get is something genuinely new and relevant to where your retention programme is today.

Why this matters for recommendations

Leon doesn't recommend
in a vacuum.

Most AI tools generate recommendations from your data alone. They have no idea what you've already tried — so they suggest the obvious things you tested six months ago and quietly dropped.

Leon is different. Before he recommends anything, he reads your Changelog. He knows your cancel flow launched in January. He knows you tested a pause offer in Q4. He knows Klaviyo is already handling your win-back sequence.

So what you get from Leon isn't a list of generic retention tactics. It's a shortlist of things you haven't tried yet, that are calibrated to your specific data, your brand profile, and where your retention programme actually is right now.

“I've looked at what you've already done. Here's what I'd try next.”

— Leon, after reading your Changelog

Who it's for

Built for retention teams of every shape.

Solo founders

When you're doing everything yourself, the Changelog keeps your retention history organised and makes sure Leon's recommendations always build on what you've already done — not repeat it.

In-house retention teams

Different people own different tools. The Changelog gives the whole team a shared view of what's live, what's been tested, and what's next — without a weekly sync just to stay aligned.

Agencies and consultants

Working across multiple brands? Log your work on each store as you go. When you hand off to a client or bring in another team member, the full history is already documented.

What a Changelog entry looks like

Straightforward to log. Powerful to have.

When teams use it

Every retention action worth logging.

Launching a new cancel flow

Log the date, the tool (Loop, Recharge, Solvpath), the step you added, and the offer. Leon won't recommend cancel flow changes until he has new data on how yours is performing.

Running a Klaviyo campaign

Log every sequence you activate — win-back, on-boarding, pause nudges. Know exactly which campaigns are live and which have already run, without digging through Klaviyo.

Testing a pricing change

Log the date the new pricing went live, the store it affects, and any notes on the setup. See the impact in your retention cohorts in the weeks that follow.
