When companies in-source services it is usually for two reasons; service level and pricing, and we know GCs have expressed issues on both fronts.

When I first looked at the figures of in-house teams and their planned growth, I was shocked.  I have spoken and written about my views on why in-house teams have grown; in particular within the piece for PLC below.  

Although the growth of some in-house teams is likely to continue, GCs are continually looking for ways to increase efficiency so that they can curb the growth of headcount.  And because "in-house" now has substantial mass, creating and developing products and services for in-house teams is becoming a sophisticated market place.  Whether that involves, Legal Project Management (which is what Halebury provides) or AI services, GCs have a great deal of options on how they want to structure and operate.
