Rex handles vendors, process, and the admin that eats your Fridays. Fred Twum-Acheampong and Jill Morgenweck review the output.
Operations is the function nobody assigns and everybody does badly. It is the vendor contract you have not compared, the process that lives in your head, the tool stack that grew by accident, and the four hours every week you spend on things that produce nothing.
Rex is the ops agent on your Marskel team. It documents the processes you are running from memory so they survive your first hire. It audits your tool stack against what you actually use and what it costs. It builds vendor comparisons with real pricing rather than marketing pages. It writes the SOPs, sets up the trackers, and produces the operating cadence that makes a one-person company behave like a team.
Fred Twum-Acheampong and Jill Morgenweck review Rex output before it reaches you. Ops is the function where Green autonomy makes the most sense soonest, since the downside of a slightly wrong tool comparison is small and the time saved is large. Most founders move Rex to Green within a month and leave the rest at Yellow.
