+MATERIALIZE BUSINESS SOURCE LICENSE AGREEMENT
+
+Business Source License 1.1
+
+Licensor:                  Materialize, Inc.
+
+Licensed Work:             Materialize Version 0.7.3-dev
+                           The Licensed Work is © 2020 Materialize, Inc.
+
+Additional Use Grant:      You may use one single server instance of the
+                           Licensed Work for any purpose and you may
+                           concurrently use multiple single server instances of
+                           the Licensed Work in isolation, subject to each of
+                           the following conditions: (a) you may not cluster any
+                           server instances of the Licensed Work together for
+                           one use; and (b) you may not use the Licensed Work
+                           for a Database Service. A “Database Service” is a
+                           commercial offering that allows third parties (other
+                           than your employees and contractors) to access the
+                           functionality of the Licensed Work by creating views
+                           whose schemas are controlled by such third parties.

+Change Date:               April 08, 2025
