Never, ever put your money into an Indiegogo project. It's not investing, as you don't earn any money. It's not purchasing, as there are no guarantees of products finishing or shipping. You also don't have any consumer protections or rights, even if the project violates Indiegogo's terms of service and commits fraud, unless you reside in the same country as the company leading the project.
Don't ask me how I know; I am still bitter.
Edit: Hardware-wise, this phone is doing a lot right: microSD, headphone jack, sim slots, NFC, and what seems to /maybe/ be a user-replacable battery without needing a new water seal on the back of the case after opening it up. IMO it falls short on RAM (16GB is the new minimum and this phone only has 8) and they used a screen with a freaking notch in it.
Software-wise, they don't seem to be doing anything new, except for offering a somewhat ready-to-go product that tried to de-google Android. This could be nice for people who don't want to spend weeks or months learning how to secure their phones themselves.
Also keep in mind that AT&T (and I believe Verizon too) do not approve of any new devices with unlocked bootloaders on their network, and as such, this phone does not support the full range of bands used by these companies. Of the three main cell network providers in the US, only T-mobile allows full access to all their bands with devices that ship with official unlockable bootloaders.
Their shipping estimate sounds like a pipe dream. There is no way this ships in March, or April, or probably even May.
