To be truly contrarian, find what's becoming the new "consensus playbook" among startups and bet against it. DoorDash chose a simple marketplace model when competitors were pursuing the trendy but complex "full-stack" ghost kitchen model, which ultimately proved to be the right decision.

The narrative that successful tech platforms are simply "rent extractors" overlooks their fundamental value creation. DoorDash, for example, created a new market for at-home restaurant dining, massively increasing the addressable market for restaurants and creating new jobs for drivers, rather than just inserting itself into an existing transaction.

In the competitive food delivery market, service fees frustrate both customers and restaurants. By eliminating this key fee, similar to Robinhood's disruption of trading commissions, DoorDash could become the preferred platform. Shifting to a subscription model like Costco would foster immense goodwill and lock in loyalty.

While competitors burned cash fighting over major hubs, delivery startup Fancy focused on Tier 2 cities. This strategy gave them a local monopoly, leading to far better unit economics and retention. This strong performance was a key factor in their acquisition by GoPuff.

While competitors viewed capital as a strategic weapon, DoorDash focused on capital efficiency. Their goal was to be twice as effective with every dollar spent on customer acquisition. Lin emphasizes that capital is fuel, but it's useless without a 'fire burning'—a product with real engagement.

The market often misjudges companies like DoorDash by focusing on the high-level service (food delivery) while missing the massive, compounding value created by its obsessive focus on fine-grained logistical details. These small, chained-together improvements create a powerful, hard-to-replicate moat over time.

DoorDash's CEO frames the market as two battles: for digital attention (bits) and for facilitating the physical world (atoms). DoorDash focuses on moving atoms (goods) to complement the digital ecosystem, which clearly defines its strategic focus against other tech giants.

Instead of creating a market expansion strategy from scratch, ServiceUp explicitly copied the playbook of DoorDash, a successful three-sided marketplace in an adjacent vertical. This involved entering a new city and simultaneously acquiring customers, suppliers (shops), and drivers, accelerating growth.

While massive "kingmaking" funding rounds can accelerate growth, they don't guarantee victory. A superior product can still triumph over a capital-rich but less-efficient competitor, as seen in the DoorDash vs. Uber Eats battle. Capital can create inefficiency and unforced errors.
