(Portland, OR) -- Portland's tech community is reeling after the death of Sam Blackman at the age of 41. The founder of Elemental Technologies reportedly died suddenly over the weekend of a heart attack. Blackman was a Portland native and took his company from a small startup to one of the city's biggest employers. Elemental Technologies was sold to Amazon a couple of years ago for nearly 300-million-dollars and Blackman stayed on as the firm's CEO.
