+        <p></p>
+        Our story roots back to 2004, when Mongoose Web Server Library development started. <br>
+
+        As Mongoose Web Server grew in popularity and matured over the following years, in 2013 Cesanta was established to continue its development and 
+        provide support to our valued customers.
+        </p>
+        <p>We are proud to have among our customers many <i>Fortune 500</i> companies as well as medium and small size businesses.
+          Security and quality of our solutions is a paramount for us and the fact that Mongoose Web Server is used by NASA aboard the International Space Station is 
+          the best confirmation to it.</p>
+          <p>Since 2013, Cesanta has expanded its product portfolio. We develop and distribute embedded software and hardware with focus on connected products and the Internet of Things.</p>
