Ask HN: Seriously, steelman this please. 7,400 employees at Docusign?
For SAAS companies that do B2B it's important to remember two arms of the company:1. Sales -> You can hire a lot of sales people if they're generating enough business to cover their own salaries2. Customer Support -> Big enterprise contracts generally have support written into them.  Thus, for every enterprise customer Docusign may need anywhere from 0.1 -> 3 (or more) FTEs. If you price this right it's always worth it to keep growing the org this way.Docusign has a lot of opportunities to upsell customers on legal services they provide.You should also consider the scaling cost of internal support. For every 10 FTEs, add a manager. Also add on HR, accounting, janitorial, etc. Easilly 20% of the company might be these sorts of internal support roles.
