Plume I spoke to the company when Plume was introduced and funded. It was concerning as an investor as yfi had been trying to get a deal and Plume walked away with a deal and cash. I was told Plume was a bandaid fix to the service call outs for wifi problems. Turns out the companies that invested in Plume saw it as far more then a bandaid. Smart initial investment to adopt Plumes tech. They have real revenue and deals. What have the years and millions done for this company? Waiting on tweets.
