Executives at in-motion, low-profile, phased-array satellite antenna supplier RaySat Inc. said the company closed a $10 million first-round investment led by Benchmark Capital and assisted by Seed Partners. The new cash will help the company tackle the multi-billion dollar U.S. rear-seat entertainment market, which entails receiving satellite TV and data in such moving vehicles as minivans, sports utility vehicles, recreational vehicles, trucks and boats.
