Venture capital (VC) finance has started to flow into Silicon Valley again after dotcom disasters and the Nasdaq crash put tech investment on hold.
Grand Central Communications, SmartPipes and Radiance Technologies have all scored key finance, signalling that the VCs are starting to get interested in IT again.
SmartPipes has raised $51m in its latest round of venture financing. Employing more than 175 people, it sells network management services, remote access and managed security solutions to telcos.
Chief executive Hank Nothhaft said that the investment should allow the company to reach positive cash flow early next year.
Grand Central, a startup that provides software to connect businesses to their partners, has raised $23m, and Radiance Technologies has picked up more than $13m.
Silicon Valley analysts are excited by the moves which are the first serious inroads by VCs into the IT industry for some time.
