Clerky actually doesn't provide their own; they line you up to use one of two services, neither of which is particularly competitively priced or well-thought-of.
Many would consider annual registered agent fees as too little money to comparison shop for, but $100+/year before you're ramen profitable might make the difference for some startups.
We actually only partner with one for new formations, and it's a great one. But yea, if you only need a registered agent, it wouldn't make sense to use us. However, if your goal is to set up a startup properly (i.e. how good attorneys in Silicon Valley would do it), then we've got what you need :)
