Wynter is so good I almost don't want to tell anyone about it so it can be my secret weapon. The experience was awesome. Many things were fascinating, I think the unexpected was that the insights we got were on both the high-level front and small details (one tester pointed out when we switched from "you language" to "us language" in the middle of a bulleted list on the page.) The big theme is just being in awe of how powerful outside perspective is and how fast and easy it was to get—so much of it is "there's no way I could expect my copywriter to know that, there's no way I would have caught that in editing/reviewing the page". Speed is also awesome. I set up the test on a Friday night, had most of the results over the weekend, we ripped apart the page and rebuilt it over the next few days, so less than a week test start to updated page.

We've now run 5 or 6 rounds of tests with Wynter and each time our positioning gets stronger. Always amazed at how quickly the feedback comes back (<24 hours) and how valuable it is. Previously we'd recruit testers through platforms like Askable, or on marketplaces like UpWork and have them go through prototypes of landing pages which would take weeks. Wynter has signifcantly sped up our learn-action cycle so we can move faster.

It's the only tool I've come across that provides measurable and qualitative feedback on copy.
