Lytro's light-field camera captured the angle of light rays in addition to color and intensity, allowing users to change a photograph's focus after it was taken, and the company shut down in 2018.
Notes on verification
Both the technical claim (light-field capture enabling post-capture refocus) and the 2018 shutdown are corroborated by multiple independent, high-quality sources including product documentation and contemporaneous news coverage.
