The honest version: cost, speed, risk and ownership, side by side. Short answer, for most teams an owned engine beats a hire on all four, until you have enough volume to keep a full-timer busy.
Short answer: for most teams under a certain scale, an owned engine built for you beats a hire on cost, speed and risk. It runs about half the loaded cost of one senior hire, goes live in weeks instead of after a 3-6 month ramp, and the capability lives in a system you own, not in one person who can resign.
Salary, NI, tooling, contractors, tool sprawl. All loaded into one number so you can compare like-for-like.
Same destination: an engine producing pipeline. One path ramps a hire for months before it produces anything. The other is live in weeks, costs about half, and you own it outright.
Producing pipeline in week one, not month four. For about half the loaded cost of a single hire.
