First there was Solarin
Designed by Karim Rashid, Solarin was the fist Sirin Labs product. This insanely expensive smartphone, made of Gold, Titanium and exotic leather, set a new world standard for security and privacy, and paved the way for the design pillars of Finney™.
The ID assets that were elected to form the DNA of Solarin descendants were: (1) Curved Top and Bottom, (2) Concave Sides, and (3) a Prominent Back Element that includes the fingerprint sensor and the main camera.
Immediately after Solarin was launched, in an unforgettable night in London, the first new design concepts were born.
This is Solarin:

Then there was Mecury
Mercury was designed to be Solarin's little sibling, for about 5K (as opposed to 16K USD) with a smaller form factor and a lesser spec. I designed it to be elegant and simple, like a luxurious fountain pen: Monolithic and self explanatory.
This was the first aesthetic model, produced by Model Solution (S. Korean top tier modelist):

Mid-2017, Sirin Labs pivoted away from Luxury. So, no more gold and no more leather.
Since my main personal goal was to make a phone which will stand out and be highly desirable, I took a lot of inspiration from sports cars (almost nobody can be indifferent to sports cars).
And so it was, that Aston Martin's side vents gave inspiration to the speaker grills; Grey Matte glass back, resembling the Matte Metallic Vinyl Wrap, which is very trendy in recent years, and expressive A-class surfaces in the back Shield element were incorporated in the design. Later on Finney's logo decorated the side, reminding the GT500 script on a Ford Cobra.

Finney™
Finney's unique selling point is its cryptocurrency hardware wallet, completely offline unless physically activated, featuring a Secure display that allows for a convenient validation of account and transaction details. The challenge was to embed a secure display while keeping a good body-screen ratio, since the second display is normally off, we didn't want it to occupy much of the phone's usable area. One option was to allocate a designated area on the main screen that could be made secure on and off with a switch, but it meant a long R&D and a large MOQ, we called this option "Secure UI". Another option was to add a small display that would occupy the curved glass area on the top of the device, which was otherwise unused, and a third option was not a desired one, however viable: On the top of the display, beside the camera. This is a study that I presented to my superiors:

It was decided that we would proceed with the Screen under the curved area ("Wishful 1") and with Foxconn's feasibility blessings for we made another prototype:

For manufacturing reasons we eventually did not proceed with this configuration. And so, the sliding safe screen was introduced, leading Finney to it's final design:
