She has been an early investor in over 30 companies including theRealReal, PicsArt, Zuora, Socialcast (acquired by VMWare), Catch (acquired by Apple), Freshplum (acquired by TellApart and Twitter), Dotomi (acquired by ValueClick), 3Ware (acquired by AMCC), WebAction, Valicert (IPO), 128Technology, Securify (acquired by Kroll), iEscrow (acquired by eBay), and many others.

Magdalena was a pioneer in the commercialization of the Internet in its early days, helping it move out of the government and university domains and in establishing the infrastructure for e-commerce and financial transaction platforms. When her plan to purchase Internet access providers from universities would not get funded by venture capitalists, she joined UUnet (IPO), the first commercial Internet access provider.

She holds Bachelor of Science degrees in Industrial Engineering and Management Science and Engineering and a Masters of Science degree in Electrical Engineering, all from Stanford University.
