This is the latest in a series of weekend posts highlighting a wide variety of applications we think are pretty cool. Most have to do with sales, marketing and productivity. Check out past featured apps here.

The B2B list business has changed dramatically in recent years, and DealSignal is an example of continued innovation and value for B2B marketers.  I highly recommend marketers build relationships with multiple list sources to ensure more complete coverage of needs – industry, comprehensiveness, etc.

What I like about DealSignal in particular are a couple things.  First, they’re more than just email and phone.  Their integration of social profiles and signals allows for far richer data and easier/faster multi-channel campaigns, across channel and between sales and marketing.  They also make quick updates on lead scoring and sales priorities a snap directly in Marketo and Salesforce.com.

Whether you need new leads or enrichment of what you already have, these guys are worth checking out.
