Addition, a venture capital firm, and Keyframe, an investment firm, led a $34m series B funding round in PassiveLogic, an autonomous building systems provider, with participation from RET Ventures, Brookfield Growth, Era Ventures and A/O PropTech. "Buildings are the world's most complex systems, a problem that increases as buildings become 'smart.' We've built a platform that tames increasing complexity and addresses the growing technology needs of the built environment. At PassiveLogic, our core focus is to redefine how people participate in the design, build, operation, and maintenance of complex systems," Troy Harvey, PassiveLogic CEO.
