<p>Cotap, a messaging startup co-founded by two ex-Yammer executives, came out of stealth last year with a very specific aim: using the boom in smartphone usage to break down communication barriers between "knowledge workers" chained to computers and employees who are front line, out in the wild, and directly interfacing with customers. Some three months after launching its first app, on iOS, Coptap is today announcing a new $10 million round of funding to build out that vision further, extending the app to Android and desktop, and hiring talent to build more features into the product, including its first tier of paid services.</p><p>As of today, Cotap has already signed up employees at 6,000 businesses to use its free app.</p><p>The Series B investment, which comes on top of a $5.5 million round last year, was led by Emergence Capital, with participation from Charles River Ventures. Both VCs were early investors in Yammer.</p><p>Cotap's debut and growth are part of a bigger consumerization trend among enterprise software developers: taking cues from the apps we use on our smartphones, tablets, and home computers, enterprises are moving away from dry and cumbersome legacy products. Workers want apps that are easier to use and more engaging, and on the IT side, the company wants services that are easier to implement and manage.</p><p><a href="http://techcrunch.com/2014/01/28/enterprise-messaging-app-cotap-nabs-10m-to-make-every-worker-a-knowledge-worker/">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.bizjournals.com/sanjose/news/2014/01/27/cotap-raises-10m-to-bring-business.html">Cotap raises $ 10M to bring business messaging to the front lines</a> (Silicon Valley Business Journal)</p><p><a href="http://www.sys-con.com/node/2944119">Cotap Raises $ 10 Million in Financing Round Led by Emergence Capital Partners</a> (SYS-CON Media (press release))</p><p><a href="http://www.vcpost.com/articles/21184/20140128/san-franciso-based-cotap-snags-10m-series-b-led-emergence.htm">San Franciso-based Cotap snags $ 10M in Series B led by Emergence Capital ...</a> (Venture Capital Post)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dfCcP2nQSy6HMzMQgWrcW3YEzaXGM&authuser=0&ned=us">7 additional articles.</a></p>
