A "research" arm is exactly this license, although it comes at the cost of potentially killing innovation in the rest of the company.
C'mon, databases are great but they are not in any way a "deep tech" field. Databases exist today in a zillion production forms as commercial products and free software.
Deep tech includes things like nuclear fusion, solid state batteries, quantum computers. I know everyone wants to feel cool, but just because your new javascript framework will be in beta for the next ten years doesn't make it "deep tech".
