Databricks was founded in 2013, but there are a few critical dates related to the “launch”:

• Spark Summit 2014: Databricks was first unveiled to the public at this conference.
• November 2014: A limited availability launch allowed some users to try the platform.
• June 2015: Databricks became generally available to all users.

If you’re looking for a single date, June 15, 2015, is the most accurate launch date when Databricks was open for everyone. However, depending on what you mean by “launch,” the earlier dates are also relevant milestones in the company’s history.
