Trial Extension Save
When an engaged trialist cancels or expires unconverted, extend the runway instead of losing them—trial length alone holds conversion flat across 24 million trials, which is exactly why a targeted extension beats a blanket longer trial.

What is it?
A trialist who used the product but reaches the end of the trial unconverted is often not rejecting the product—they ran out of evaluation time. A team mid-rollout, a stakeholder on vacation, a procurement cycle that outlasts the trial: these are calendar problems, not product problems. Cancelling that trialist throws away an evaluation that was still in progress.
This tactic offers an extension at the moment of loss—when the trialist hits cancel, or when a trial is expiring unconverted with real engagement signal behind it. The trialist accepts the extension, the trial end date moves, and the evaluation continues instead of restarting from zero with a competitor.
What the evidence shows
Across 24 million trials in the platform dataset, trial length by itself does not move conversion: rates hold flat at 10 to 13 percent whether the trial runs 3 days or 30. That finding is the foundation of the tactic, because it rules out the obvious alternative—simply making every trial longer buys nothing.
What the flat curve implies is that time only matters for trialists who are actually using it. A targeted extension for engaged-but-unconverted trialists is the surgical version of "more time": it spends runway only where an evaluation is genuinely underway. The targeting logic is well-supported; the extension’s isolated lift is still being measured, which is why the grade sits at moderate rather than strong.
How it runs
In production, the extension is gated on an engagement floor—sessions, core actions, or whatever signal the org treats as evidence of a real evaluation. An engaged trialist who hits cancel sees the extension in the Cancel Flow; an engaged trial expiring unconverted can surface it in-app before the deadline. Unengaged trialists never see it, because extending them just delays the same outcome.
The offer itself is plain: the new end date is stated explicitly, the trialist accepts it rather than having it applied silently, and each trial gets one extension. The single-extension cap keeps the trial a trial—an evaluation with a deadline—rather than an indefinite free tier negotiated one cancel at a time.
