The 4,000-Person Beta: What We Learned Building ZENYVA

In 2024, we recruited 4,000 beta testers from our early community to try ZENYVA and report back on their experience. The results shaped the product you see today.

The most consistent feedback was about energy. 73% of beta testers reported sustained energy throughout the day without the crash associated with caffeine or stimulants. Sleep quality improved for 68% of users within the first three weeks. And perhaps most importantly, 91% said they would recommend ZENYVA to a friend.

Iterating Based on Feedback

But we did not just celebrate the wins. We dug into the negative feedback too. Some users experienced mild digestive adjustment in the first week. That led us to refine the capsule formulation and add clearer instructions about taking ZENYVA with food.

Every piece of feedback became a data point. Every data point became an improvement.
