What the estimate $ ?
We're going to be moving forward under the expectation that future Pixel devices may not meet the requirements to run GrapheneOS (https://grapheneos.org/faq#future-devices) and may not support using another OS. We've been in talks with a couple OEMs about making devices and what it would cost.

A new device effort will cost millions to get something slightly below the same level of what we have now.
Millions is the broad term. If it’s a ten million dollars then I guess it’s possible to fund rise if hundreds then gonna be tough
It shouldn't be that high hopefully. It would likely be an OEM making a variant of their existing device but designed for GrapheneOS.
