Morphology
This is a metaphorical extension of the physics term: 'escape' (getting away) + 'velocity' (rate/speed) reasonably suggests the speed or momentum needed to break free of something, so a learner who knows both words could infer a general sense of 'growing quickly enough to get free'. However, the specific business nuance — becoming self-sustaining and no longer needing external funding — is specialized and not fully predictable from the literal constituents, so it is only partially transparent.
Etymology
Escape velocity comes from physics and paints a simple picture: a rocket must reach a certain speed to get away from a planet's pull. The word escape means to leave and velocity means speed, so the phrase refers to the smallest speed needed to 'break free' from gravity.
