Once the executive has earned the team’s trust and credibility, consider promoting him or her. - Reid Hoffman

Blitzscaling means that you’re willing to sacrifice efficiency for speed, but without waiting to achieve certainty on whether the sacrifice will pay off. If classic start-up growth is about slowing your rate of descent as you try to assemble your plane, blitzscaling is about assembling that plane faster, then strapping on and igniting a set of jet engines (and possibly their afterburners) while you’re still building the wings.

Despite all the chaos, and the inefficiency of manufacturing and shipping in small batches, Zara’s gross margins continue to exceed those of its competitors H&M (55 percent) and Gap (29 percent). That’s because all that inefficiency incurred in the pursuit of speed allows Zara to avoid one of the biggest drags on gross margin for almost any apparel company — overstock of designs that failed to sell. Ortega devised this model when he was sixteen years old — don’t order inventory and hope it sells; instead, figure out what people want, and then make it.

we suspect that the market for food delivery from existing restaurants — a pure commodity business — is unlikely to offer any lasting competitive advantages that would justify an expensive blitzscaling campaign.
