Businesses become critically dependent on platforms for even a small fraction of their revenue (e.g., 20%). This 'monopsony power' creates a stronger lock-in than user network effects, as losing that customer base can bankrupt the business.

While most tech giants focus on the digital world of "bits," Amazon's true dominance comes from its mastery of the physical world of "atoms." Its massive, hard-to-replicate logistics infrastructure for moving goods creates a formidable competitive advantage that software-only companies cannot challenge.

You don't need massive scale to achieve group-purchasing power. By finding another company with a similar order and simply doubling the volume presented to a factory, a sourcing platform can negotiate price drops of 20-30%. This makes demand aggregation highly effective even at an early stage.

While AI agents could shift sales away from traditional retailers, companies with extensive physical infrastructure and forward-positioned inventory have a defense. AI agents prioritizing speed and efficiency for physical goods will likely still favor these established networks, preventing full disintermediation in the new agentic commerce landscape.

Zalando leveraged its extensive European logistics footprint, initially built for its B2C business, into a new B2B revenue stream. Brands can now use this infrastructure to manage their own e-commerce fulfillment across the continent, avoiding massive CapEx and gaining network benefits.

Marketplaces like DoorDash are more than just software; they are logistics and customer service networks that solve messy, real-world problems. An AI agent can discover a restaurant, but it cannot handle a cold sandwich or a refund, giving these physically-integrated companies a durable moat against pure software disruption.

Scale creates a powerful barrier to entry in logistics. A dominant provider with a vast network can add a new, specific service (like pallets for celery) to its existing operations far more cheaply than a new competitor could build a network for that single service, effectively locking out competition.

To solve the classic marketplace problem where buyers and sellers connect and then transact offline, Sorcerer acts as the supplier itself. It operates a 'blind escrow marketplace,' ensuring all transactions flow through its platform and protecting its business model, rather than just acting as a connector.

To avoid being disintermediated by AI agents that could direct consumers elsewhere, retailers can leverage their physical assets. An AI agent will still prioritize retailers with extensive infrastructure and forward-positioned inventory to ensure fast and efficient delivery, creating a competitive moat against pure-play e-commerce.
