I respectfully submit the Keyhotee moniker is inadequate and may hinder widespread adoption.
First issue: too many syllables.
If you look at the most successful tech branding campaigns of the 21st century you will find convergence at two syllables:
Apple (to wit - iPhone/iTunes)
There is likely psychology and good reasoning behind this, but bottom line is people seem to identify with two-syllable tech branding. Proof is in the pudding.
Second issue: not connected with the bit-space.
My recent experience as an 'average Joe' just learning about the Invictus project was frustrating when it came to Keyhotee. I had a hell of time figuring out what Keyhotee is.
I can tell you with 100% certainty that the Keyhotee branding does not resonate with the target audience, and moreover, is a bit off-putting. It looks like antivirus software from the 90's.
The phonetics and logo create a disconnect with the 'bit' ecosystem that alienate the project from the crypto/decentralization movement.
Apologies for being harsh, but I do feel strongly about this. The technology is incredible, game-changing, needed.
So what to do?
Treat Keyhotee as a code-name, similar to what Intel/Microsoft/others do pre-release, and then re-brand on launch.
Re-brand to what? Anything with 'bit' in it. The obvious candidate being BitMail (bMail? bitMail? bitmail?).
The unavoidable association will be with gmail, which is highly desirable as it will accelerate adoption. Think gmail minus Google plus crypto.
Association with a familiar, mature and widely adopted brand/product will massively lower the entry barriers for adoption.
Moreover, the bit-space is rapidly becoming recognized as next-gen, secure, decentralized, private, etc.
BitMail leverages both spaces in two syllables.
Imagine you are average Joe and someone is pushing a new email client: you can choose to download and install Keyhotee or bitMail. Which one do you pick?
