I have no inside look and can only comment as a user, but isn’t a company like gusto providing a genuinely valuable service? As a small time startup operator I was happy to pay for their product.
Companies like that are relatively niche and usually already have all the talent they need. Not to mention, even if it looks good on the surface there could still be bad things hiding under the hood. A friend of mine works at a niche business selling network hardware, sounds innocent enough - and yet they are using creepy analytics to infer which companies visited their website and then spam them with sales calls.
