Investment thesis
15th Rock is a venture capital firm focused on 'human augmentation,' backing technologies that use the power of technology to expand the abilities considered normal for humans today — imagining futures where people might control anything by thought alone, fly, or become invisible. The firm believes that achieving unparalleled success in the vast ocean of startups requires doing something different from others, but that this differentiation must also be correct.
