  This Letter presents the detection of a source at the position of the Type
Ib/c supernova (SN) 2013ge more than four years after the radioactive component
is expected to have faded. This source could mark the first post-SN direct
detection of a surviving companion to a stripped-envelope Type Ib/c explosion.
We test this hypothesis and find the shape of the source's spectral energy
distribution is most consistent with that of a B5 I supergiant. While binary
models tend to predict OB-type stars for stripped-envelope companions, the
location of the source on a color-magnitude diagram (CMD) places it redward of
its more likely position on the main sequence (MS). The source may be
temporarily out of thermal equilibrium, or a cool and inflated non-MS
companion, which is similar to the suggested companion of Type Ib SN 2019yvr
that was constrained from pre-SN imaging. We also consider other possible
physical scenarios for the source, including a fading SN, circumstellar shock
interaction, line of site coincidence, and an unresolved host star cluster, all
of which will require future observations to more definitively rule out.
Ultimately, the fraction of surviving companions ("binary fraction") will
provide necessary constraints on binary evolution models and the underlying
physics.
