Dolly's original fulfillment algorithm (pairing supply with units of demand) was predominantly SMS'ing independent contractors (that had previously signed up) to see if they were interested in the gig. A ton of text messaging behind the scenes. Eventually we automated out a whole suite of fulfillment systems that have scaled into 6 figures worth of orders. It's amazing what you can do with clear inputs & outputs and the illusion of a black box until you can actually build your black box.
