Ojo Labs, an Austin-based startup developing an AI-driven personal assistant for realtors and homebuyers, today announced that it has raised $45 million in a series C financing round with participation from LiveOak Venture Partners, real estate and relocation services company Realogy Holdings, Royal Bank of Canada, and Northwestern Mutual Future Ventures. It comes mere months after Ojo completed a $20.5 million series B round and follows on the heels of its acquisition of WolfNet Technologies, a real estate data broker, and it brings its total capital raised to $65.5 million.
