+# Ossum with Gerrit!
+
+To address the needs of modern software development teams, CollabNet launched a new SaaS
+product earlier this year: [*ossum*](https://www.ossum.cloud/).
+Ossum streamlines development process from idea to release while advocating use
+of best software engineering practices. What comes to its version control and
+code review capabilities, ossum heavily relies on Gerrit.
+
+Almost decade ago, CollabNet tightly integrated Gerrit with their flagship product,
+TeamForge, making ossum CollabNet’s second product using Gerrit as its Git backend.
+
+In addition to a brief introduction to ossum, this lightning talk will cover why we
+chose Gerrit (again!) and what are some lessons learnt from TeamForge.
