Vessyl Production Update

What’s happening with the original Vessyl?

Many of you are asking this question, and we’d like to share an update on where we are with Vessyl development. In October we mentioned that we were going to take some time to assess what is truly needed to get Vessyl to a place where it will actually help you get healthier. Unfortunately, as of yet we have not met that standard. Though we’re able to build a small number of Vessyls with this technology, it’s critical that every Vessyl we ship has the accuracy and reliability of the one before it.

All of our backers have shown immense patience and support, and we don’t take that for granted. You’ve waited a long time, and in that time we’ve changed parts of the technology to meet our goal. We are asking for a bit more time to assess additional technologies that can supplement the current sensors to achieve the standards we desire. With the success of Pryme Vessyl, we are hiring more talented folks to help manage both products.

We will be doing a comprehensive review of our current technology and some additional technologies. In March, we’ll be able to give you a more accurate timeline on the delivery of your Vessyl.

Below is a link to an early press demo of the technology we are improving…


Where’s my free Pryme?

The quick answer to this is… it’s on the way. The response to Pryme Vessyl has been great; so great that the retail demand threw our estimates off balance, leading to supply constraints. Due to these supply constraints, we are slowly moving through the list of free Prymes. If you haven’t already received a free Pryme, look out for an email from us in the coming weeks to get your shipping information. Note that orders outside of North America will see some delays due to customs. We are putting a solution in place to ensure international orders are delivered on time. We’re also prioritizing orders for those with iOS devices until we complete the Pryme app for Android.

In an effort to better fulfill the demand for Pryme, we are shifting our manufacturing to a larger facility. This will also expedite the shipment of free Prymes.

As always, if you have any questions or comments, you can reach out to us at
