Networking startup Altiostar Networks—whose CEO is Ashraf Dahod, formerly the founder of Starent Networks—has disclosed adding $20 million in funding to its latest round.
The new funding was disclosed in a filing Tuesday with the U.S. Securities and Exchange Commission. The money is an addition on top of the company's $50 million raise that was disclosed in January.
Investors in the Tewksbury, Mass.-based company have included Cisco Systems, Excelestar Ventures and the company's founders.
Altiostar has now raised $140 million in equity funding since 2012, according to SEC filings, making the firm one of the best-funded tech companies in Boston.
In November, the startup came out of stealth mode with its technology focused on improving LTE networks.
Previously, Dahod founded Tewksbury-based Starent in 2000 and was its CEO through its IPO in 2007 and its acquisition by Cisco in 2009 for $2.9 billion.
