“we have a fellowship program where basically you can raise your hand and say for the next three months instead of doing my job I want to go and figure out how to make my team faster how to use technology to make my team faster”

Run a "builders" fellowship to surface internal growth talent

Don't try to top-down assign which people inside the company will drive AI / growth experimentation. Instead, run a 3-month fellowship: anyone raises their hand, gets pulled off their day job, and is paid to figure out how to make their team faster with new tools. The self-selectors are exactly the people you want — agency-seekers who will keep doing it after the fellowship ends.
