Investments in water treatment and conservation technologies have been funded by $3.1 billion in private investments since 2007, and the innovation sector is a fraction of water activity overall. Mergers and acquisitions (M&A) dominate in the water sector with a diverse group of buyers, frustrating venture capitalists who hold initial public offerings (IPO) as the gold standard. In the water industry, M&As dominate and give a better, and more timely, return on investment. While outsiders see it as monolithic, water is a highly fragmented industry. Each sector of water is unique, with different timelines for venture funding, growth equity, and exit windows. Investors and buyers alike will find opportunties in active regions of the hydrocosm.
