New entrants very often spin out from established firms and because they set on a course at
founding, their learning and capabilities become inextricably linked to their organizational and
technological heritage. But while this heritage may provide an initial advantage, it can also
generate inertia and resistance to change, unless the new company is able to unlearn some
practices from the parent company and learn something new in order to establish its own sources
of competitive uniqueness. This tension between inherited path and new trajectory, imprinted
past and search for newness is the object of this paper. Building on an in depth case study of
Acorn Computers and ARM semiconductors we show that while there are strong influences from
the parent company on the spinoff, these imprinted organizational effects can be overridden. We
use the term deprinting to stress the reversible nature of this process in contrast with the
irreversibility embodied by the classic imprinting notion. This is followed by a phase of intense
learning efforts whereby the spinoff establishes its competitive identity based on a blending of
retained routines, repeated improvisation and feedbacks from the market. We refer to this process
with the term reimprinting, to emphasize the metamorphosis experienced by the spinoff as it sets
on a new distinctive trajectory
