Speakers from Adobe, IBM, Cigna and Avaya have been added to the agenda at this month’s B2B Content2Conversion Conference, taking place April 22-23 in New York at The TimesCenter.

“It’s an honor to us that key marketing leaders from companies large and small are recognizing the B2B Content2Conversion Conference as a must-attend event,” said Andrew Gaffney, Editor-In-Chief at Demand Gen Report, which is hosting the event. “These new speakers add an extra level of excellence as we strive to create an event that provides great networking opportunities, top-notch speakers and business-changing marketing tactics.”

KnowledgeVision Systems, a provider of online video presentation technology, has announced the closing of $1.875 million in new financing from institutional, private and strategic investors, according to a company press release.

The funds will be used for new product initiatives and to support the company’s rapid customer growth.

HubSpot announced the availability of RetweetLab, a free tool for marketers to analyze their Twitter account as well as their competitor’s to measure the effectiveness of tweets.

RetweetLab also measures the impact of hashtags on retweets from Twitter accounts and offers a breakdown of the time of day the account receives the most retweets. In addition, the new tool analyzes the impact of call-to-action within tweets, such as “please retweet.”

Since being acquired by Silverpop a year ago, CoreMotives has increased billings by 136% and added more than 270 customers, bringing the total to 1,500 brands currently using the tool to deliver marketing campaigns from within Microsoft Dynamics CRM.

Demand Gen Report spoke with Rhett Thompson, Co-Founder of CoreMotives, and Ellen Valentine, Product Evangelist for Silverpop, about the status of the partnership and the future.

ReachForce, a provider of data management systems for B2B marketers, acquired SetLogik, a vendor of cloud-based data and analytics technology, to develop the Connected Marketing Data Hub.

The Connected Marketing Data Hub offers an integrated suite with continuous data quality management and predictive marketing capabilities, said ReachForce officials. Through its integration with a number of marketing and sales automation platforms, including Marketo, Eloqua and Salesforce.com, it enables marketing professionals to more effectively collect, qualify, target, and convert leads throughout the buyer’s lifecycle.

Marketo has followed through on its plans to file an initial public offering (IPO), a move which also pulled back the curtain on the company’s finances, including a high growth rate and big losses. The company plans to trade as “MKTO” on the Nasdaq. Goldman, Sachs & Co. and Credit Suisse are listed as leading the offering.

The S-1 registration statement provides a wealth of new information about Marketo’s business. Revenue for 2012 is reported at $58.4 million, an impressive 80% growth rate vs. 2011 although not quite the doubling that the company had forecast earlier, according to David M. Raab, Principal of Raab Associates.

Data analytics has never lacked for coordinates. Filling a spreadsheet with lead scoring algorithms, customer retention costs or predictive conversion metrics is second nature for most B2B marketers.

While the coordinates have provided an embarrassment of riches, the accompanying cartography has been barren. However, analytics is about to get a new set of maps.

Demandbase last week announced the closing of a $15 million funding to support accelerated growth of the company’s online advertising and web site optimization platform, according to Demandbase officials.

Demandbase Founder and CEO Chris Golec believes that B2B marketers have not yet taken full advantage of the reduced cost of selling made possible by digital marketing and data-driven decision making. “The new investment will help fuel our growth and fulfill our vision of creating connected conversations with prospects and customers across traditionally siloed technologies and data,” he added. “Online advertising, web site logs, and CRM systems can finally be joined in real-time to connect advertising spend to web site engagement to company revenue.”
