IPO action is showing signs of heating up with Monday's filings by flash storage startup Violin Memory and cloud telephony company RingCentral writes Cromwell Schubarth, the Senior Technology Reporter at the Silicon Valley Business Journal.
RingCentral has its headquarters in San Mateo. Violin Memory is moving its headquarters to Santa Clara, from Mountain View.
The year started slow with only four initial public offerings in the first quarter, kicked off by San Francisco money transfer company Xoom in February.
There have been eight more in the six months after that ice-breaker, with Milpitas data traffic management software company Gigamon raising the most money, taking in $128.25 million in June.
Three IPO plans filed this month would top that: Violin Memory hopes to raise up to $172.5 million, Milpitas-based security software company FireEye plans to raise $175 million and Santa Clara textbook rental/student hub company Chegg plans to raise up to $150 million.
