The Wall Street Journal (WSJ) reported Tuesday that private equity powerhouse Kohlberg Kravis Roberts & Co. L.P. (KKR) has invested $90 million for a 35% stake in Savant Systems, LLC (Savant). While this is a minority stake, KKR is obviously bullish on the home automation supplier making what the WSJ says is an “eight-figure bet” that places a $215 million valuation on the home automation supplier.
