At https://www.thethingsindustries.com and the open source LoRaWAN developer platform https://www.thethingsnetwork.org we used to do a lot of hardware ourselves: https://www.kickstarter.com/projects/419277966/the-things-ne....

Now we do very little and only focus on the SaaS network management part of it. We still have this product www.genericnode.com

We now have 220 hardware partners that can do it much much better than us: https://www.thethingsnetwork.org/device-repository/
