Seattle-based Rover.com, an online network of pet-sitters and dog-walkers, has raised a $40 million Series E round led by Foundry Group and Menlo Ventures with participation from Madrona Venture Group; all three firms were already existing backers. The company has now secured about $90 million in total funding, including a $25 million financing in March 2015 at a $138 million valuation.
Founded in 2011, Rover has a bit of an atypical history. Greg Gottesman, then a managing director at Madrona, originally pitched the company's concept at a hackathon called Startup Weekend in Seattle. He then gathered a team to build a prototype over the course of the weekend, and the team went on to take first place in the competition. The company has continued to grow and gather new funding ever since.
