Cirrus Logic, which supplies signal processing chips for the audio and energy industries, sponsors major live-music shows and a monthly “Cirrus Rocks!” concert series for employees and their families. Fun is everywhere here, with events like pie bake-offs, VIP tickets through sponsorship of the giant SXSW Music Festival and the annual company-sponsored “Corporate Battle of the Bands” that raises money with local charities for under-insured local musicians. Referring new employees can score you up to $20,000 and a new iPad, and milestones in product technology development are celebrated with keggers on the huge deck along Shoal Creek in downtown Austin.
