🎉 Exciting News!

Grumpy Mesh has officially reached an agreement with a distributor!

Even more exciting, this distributor is already an approved vendor for many public safety agencies, hospitals, and commercial businesses. This will make purchasing a Grumpy Mesh King Repeater significantly easier for organizations that normally have lengthy purchasing requirements.

While we aren't ready to announce the distributor just yet, we're excited about what this partnership means for the future of Grumpy Mesh and the communities we serve.

More details will be announced as we get closer to the official launch of the Grumpy Mesh King Repeater.
