The most common types of tasks I've seen are those that fall under business operations. My last company when starting up their B2B side had someone manually set up invoices in Excel and print and mail them to the individual clients. For some clients I've seen people manually enter data instead of automating it (or until the automation is complete). The real trick here is that you don't want to automate the operations until you actually have a product that people are buying. It's not worth investing the time and money into automation unless you know it's going to be used. Additionally, early on, you're going to want to do some of the sales manually. You're probably going to lean on people you already know to try the product and intros from people in your network. This is more time-consuming than a sales pipeline but it will generally provide better product (and sales) feedback. These customers will also most likely be your most passionate.
