Building networks for agents

The Core Question

The a16z crypto brief asks whether autonomous software agents can replicate the network effects that made platforms such as Uber successful, but for far more intricate transactions. While Uber matches a rider’s simple request for a ride with a driver’s availability, the report envisions agents handling multi‑dimensional preferences—time windows, budgets, dietary restrictions, and more—across a wide range of markets.

Method and Conceptual Framework

Rather than presenting empirical data, the report builds a conceptual model. It draws a parallel to existing crypto‑based intent systems like UniswapX, where users post orders and liquidity providers compete to fill them. By inserting large language models (LLMs) to translate natural‑language conversations into structured intents, agents could automate the search, negotiation, and execution phases of complex purchases. The authors illustrate the idea with a dinner‑for‑six scenario, showing how personal agents could aggregate group preferences and solicit offers from restaurant agents.

Main Findings

The report concludes that agent‑driven marketplaces could generate powerful network effects. Each new restaurant or supplier adds a matching opportunity for more buyer groups, and each additional buyer group creates more demand for suppliers, reinforcing participation. It also highlights a viable business model: agents could operate for free to users while capturing the price differential between the buyer’s budget and the supplier’s quoted cost, akin to payment‑for‑order‑flow. This fee structure would fund the computational overhead of running LLMs and maintain user trust through transparent pricing.

Caveats and Challenges

Scaling such networks demands robust trust infrastructure. Agents must prove authority to commit funds, guarantee fulfillment, and manage cancellations or disputes. The report warns that without reliable escrow or reputation systems, participants may hesitate to delegate purchasing decisions. Moreover, regulatory scrutiny around fee structures and data privacy could shape how these platforms are built.

Implications for Readers

For entrepreneurs, the brief suggests a pragmatic entry point: launch an agent marketplace in a single city’s dining sector, prove time‑ or cost‑savings for users, and demonstrate incremental revenue for restaurants. Success there can be leveraged into adjacent verticals like travel, B2B procurement, compute capacity markets, and even credential or health‑data networks. For investors and analysts, the key takeaway is that the value of an agent network will increasingly hinge on the depth of its participant pool rather than the sophistication of its software alone.

Overall, a16z crypto posits that the next wave of platform economics will be driven by autonomous agents that make complex, multi‑criteria transactions as frictionless as ordering a ride today.
