<p>After a little bit of a rough start, the automatic address book updating service WriteThat.Name has become one of my preferred "set it and forget it" tools for keeping things organized. Built by Paris-based Kwaga, WriteThat.Name is one of those under-the-radar technologies that doesn't get a lot of media attention, but is slowly approaching profitability with more than 40,000 paying users and revenue growth of more than 15 percent month-over-month.</p><p>For those who missed it the first time around, the company last year launched a service that tackles an area in need of more attention and solutions: the address book. While a number of companies, including LinkedIn, Brewster, Cobook and recent Yahoo acquisition Xobni, have built standalone apps meant to replace default address books on mobile devices, WriteThat.Name is less focused on the user interface (that's still your call), and more on the content that is, the actual names, phone numbers, addresses, email addresses and more that fill out a user's contact info.</p><p>Initially, I'll admit I was not thrilled with Kwaga's product. After glowing reviews on the web promised a marvel, I was disappointed to find it engaging in some spammy techniques involving emails sent on your behalf that you couldn't opt out of without paying. But credit where credit is due: the company immediately responded to these concerns, and stopped that behavior. I signed up and have been using it ever since.</p><p>Here's how it works: you either authorize the service on your Gmail account or install an Outlook plug-in and choose one of the company's plans. There's a free tier for those who just want to check it out, and others are priced reasonably at $35 or $59 per year for additional features. WriteThat.Name will scan through your email automatically, then update your address book using the data found in senders' email signatures. You can also buy an add-on called "Flashback," which will dig into the past year or five years of your email archives to get you all caught up.</p><p><a href="http://techcrunch.com/2013/09/26/writethat-names-new-chrome-extension-updates-your-address-book-or-crm-with-contact-info-found-online/">Keep reading...</a></p>
