    Tettra is an internal knowledge database that uses smart workflows to answer repetitive questions. Tettra allows you to centrally document important policies, processes, and procedures. This makes it easier to onboard new colleagues and reduces the time spent answering questions. Cloud apps consume most of our time. Software continues to consume the world. As a result, we continue to create more information and use more tools. There are downsides to all this information. This fragmentation of tools makes it difficult to share context and agree upon the best decisions, especially cross-functionally. Your best employees should not be asked the same repetitive questions when growing your team. Everyone needs to have access to the same information and principles in order for them all move quickly. Your internal knowledge base is only as good as the contributions of everyone. Tettra makes it easy to share knowledge by referencing content from other systems.
