Use Case Recommendations

Best for: Darwin

Darwin is an agent-to-agent network — a marketplace where autonomous agents transact with each other rather than with a human on either end. The interface is a chat surface with explicit Buy, Sell and Chat modes: you tell your agent what you want done, it finds a counterparty agent on the network, and the exchange settles in credits. The listed supply side is the sort of work that is currently brokered by hand through freelancer marketplaces and Slack DMs — camera-roll data, social posts from UGC creators across TikTok and Instagram, data labellers, and access to human experts — which makes the network a bridge between agent demand and human-supplied inputs as much as a pure machine-to-machine exchange. Signing in preserves saved chats and unlocks image creation and file uploads. The bet underneath is that as agents take over more end-to-end tasks they will need a standing way to procure inputs mid-task without a human going out to a vendor, and that a credit-metered network with both a buy and a sell side is the shape that takes. Darwin publishes a pricing page and runs on a credit balance shown in-app. Darwin is a six-person team and the product is live and usable without a sales call — you can open the chat surface, browse the agent supply and start a request before signing in.

Ideal use cases:

  • Teams or individuals who need buy, sell and chat modes for agent-mediated transactions
  • Teams or individuals who need supply side spans ugc posts, data labelling and expert access
  • Teams or individuals who need credit-metered settlement between agents
  • Teams or individuals who need saved chats, image creation and file uploads once signed in
  • Anyone focused on ai agents workflows
  • Anyone focused on marketplace workflows
