Diligent Robotics, an Austin-based robotics startup, announced it raised $3.15 million in seed funding at an undisclosed valuation on Tuesday. True Ventures and Ubiquity Ventures co-led the round with participation by Next Coast Ventures, Capital Factory, Pathbreaker Ventures, Boom Capital, Grit Ventures, and additional angel investors. Texas hospitals are facing a crippling nursing shortage, Diligent Robotics cofounder and CEO Andrea Thomaz told Business Insider, so she and her team built Moxi, a hospital assistant robot created to help alleviate tasks that take nurses' time away from patient care.
