The investment is a Series F, with prior investors Institutional Venture Partners, InterWest Partners, Mayfield Fund and Storm Ventures also participating. Neeraj Agrawal, a Battery Ventures general partner, will join Marketo’s board of directors.

Marketo CEO Phil Fernandez told me that he hadn’t been on the hunt for more funds. But recently he and his board decided to open the door to investors just a crack, and suddenly had many venture capitalists knocking. “The opportunities we’re seeing are just huge, and we decided to take an investment and grow the company,” Fernandez told me yesterday. “I’ve had a continuous stream of investors over the last year.”

Agrawal, in particular, had been interested in investing since early this year, and persistently kept in touch, Fernandez said. When the opportunity came, he jumped.

The investment, Fernandez says, gives Marketo a $70 million war chest that he intends to use to bulk up his team. “It gives us some working room to make some investments, to do some international expansion.” When I talked to him yesterday, he called from London, and said the new money will help fuel expansions into Latin America and Asia.

So what does Marketo do? It helps companies find and track sales leads and prospects using social media, the Web and in-person contacts at events like trade shows, in order to identify customers who are ready to buy — or, as Fernandez says, “the hottest of the bunch.” There’s also a set of analytics tools that helps companies sift through the many threads of data related to making sales and keeping customers. “It helps companies to understand how and why they’re growing, and then how to accelerate that growth.”

So far, Marketo has 1,500 customers, including eBay unit PayPal; McKesson, a $112 billion (2010 sales) health IT concern; and Rackspace, the Web- and cloud-services hosting provider. Those customers are hungry for more new products and services, Fernandez says, so more products are on the way. “We have three products, and a fourth cooking away in the oven,” he says.

Sales were in the ballpark of $14.5 million in 2010, and Fernandez says he’s on track to more than double that this year, which implies sales in the mid-$30 million range, all of it recurring revenue. He says he thinks he can grow it by 100 percent again into 2012.

Also: Acquisitions. Fernandez wouldn’t name any targets — who would? — but he did say he’s got some names in mind. “There’s an awful lot of innovative little companies out there that have a great product, but maybe didn’t build the same successful channel that we did,” he says. “So there’s a good chance to quickly monetize some products that we would acquire. We’re hot on the trail.”

Finally, Fernandez says Marketo is starting to mull an IPO. He’s not in any rush, and hasn’t hired any bankers yet. “We’re pretty aware that if we keep growing the way we have, we’ll be in a place where we can go public if the markets are open, so, we’re thinking about it.”

The search giant is leading a $23 million series D round in Invidi Technologies, a New York City company that works on “addressable” TV ads. Addressable ads are supposed to target specific viewers, using data from set-top boxes, in the same way that Internet ads sniff out specific Web surfers.

You can see why Google (GOOG) would be interested in this stuff, particularly as it tries to integrate its Android platform with TVs. Shishir Mehrotra, who runs product management for all of Google’s video businesses, will join Invidi’s board.

Addressable ads are a holy grail for the TV business, but they may still be several years away. Invidi, founded in 2000, has completed two market trials to date.

People familiar with the transaction tell me Google has invested between $10 million and $15 million in company in this round, which brings Invidi’s total capital raised above the $85 million mark. Other investors include WPP’s GroupM, Motorola (MOT), Menlo Ventures, InterWest Partners and EnerTech Capital.

Business Insider, which first reported the investment, says the transaction is connected to Google’s ad pact with the Dish satellite network. But I’m told Dish doesn’t factor into the deal.

Last night, I was the master of ceremonies, as I have been for several years, at the laudable annual Astia Awards Dinner, which celebrated venture capital firms that support women-led companies.

And VC Tim Draper really went above and beyond in showing–quite literally–his support for his female entrepreneurs.

The San Francisco-based nonprofit does work to accelerate funding and growth of early-stage women-led businesses in life sciences, high technology and clean technology, with chapters in Silicon Valley, London and New York.

The NVCA member firms honored at the show, which is sponsored by Deloitte and Fenwick & West, by Astia for making the most investments in companies with a woman CEO were Draper Fisher Jurvetson, InterWest Partners, Prolog Ventures and Redpoint Ventures.

In addition, Allan Will, founding managing director of Split Rock Partners, received the Deloitte Leadership in Mentoring Award for encouraging female CEOs in technology-based fields.

Other award winners this year included: Anu Acharya, founder and CEO of Ocimum Biosolutions, who got the Life Science Innovator Award; Diane Greene, founder of VMware, who was awarded the Technology Innovator Award; and Pam Marrone, founder and CEO of Marrone Organic Innovations, who received the Clean Tech Innovator Award.

But it was Draper who stole the show, held at the de Young Museum in San Francisco’s Golden Gate Park.

He could not attend, but made his presence known by doing a video in which Draper sings very badly, but with incredible enthusiasm.

But before he starts crooning, Draper takes off an article of clothing for every woman-led company he funded.

Let’s just say, while he should be proud of his investments in women CEOs, it would have gotten very dicey if DFJ had done just one more.

But see for yourself–or, more correctly, see a lot of Tim Draper, in this video:
