Hi! We've been using GrowthBook as our A/B testing platform for almost a year, and it’s been fantastic. Over the past six months, we’ve run several successful tests that showed significant growth in conversion and revenue. My gut feeling tells me our users' LTV should be increasing, but a few days ago, I compared the June 2024 cohort with the December 2024 cohort and calculated D28 RLTV (proceeds within the first 28 days). Surprisingly, there was almost no difference. This has left our team confused—we see continuous growth month over month, but it seems like this growth is purely driven by acquisition rather than improvements in activation and engagement. Is there anyone in the community with deep expertise in A/B testing who could conduct an audit as part of a paid consultation?

Hi Andrey, glad you're liking the product
