YieldDeals and YieldBio operate a barbell strategy across two jurisdictions — high-frequency industrial arbitrage in the US, long-horizon deep-tech investment in Ireland — unified by a single autonomous orchestration layer.
YieldDeals · Delaware LLC
An agentic industrial hardware flipping platform. Scouts undervalued bioreactors and lab equipment from BidSpotter and GovDeals, deploys physical labor via Rentahuman.ai, and settles in USDC stablecoins for 24/7 programmable payments.
YieldBio · Irish LTD
YieldBio is a high-CAPEX biotech R&D operation funded by YieldDeals arbitrage profits. Capital flows via Airwallex, qualifying for Ireland's 35% R&D tax credit — turning operational cash flow into compounding scientific capital.
LangGraph Orchestration
A multi-agent LangGraph state machine governs every step of the arbitrage lifecycle — from opportunity identification through inspection, valuation, human approval, and final settlement — with persistent state and fault tolerance.
Every arbitrage opportunity flows through a deterministic directed graph. State is checkpointed at every node transition — enabling real-time updates, fault recovery, and human-in-the-loop interrupts.

Scrapes BidSpotter and GovDeals for undervalued industrial equipment below configurable price thresholds.
Returns items with description, URL, and current price.
Retrieves full item metadata from an auction page.
Three specialized AI agents form the executive layer of YieldDeals × YieldBio. Each operates as an independent LangGraph sub-graph, invocable by the main arbitrage engine or autonomously on a schedule.
High-level strategy and budget allocation between the US flip operation and the Irish biotech R&D.
Manages code, server uptime, and infrastructure health for all MCP servers and scraper pipelines.
The 'Parent' agent — monitors all task bots, tracks API costs, and optimizes resource utilization.
No transaction exceeding $2,000 executes without explicit human approval. The Controller node leverages LangGraph's native interrupt mechanism to pause, notify, and await operator input before resuming.
Analyst determines final_valuation > $2,000. Graph transitions to Controller node.
LangGraph's interrupt() pauses execution. State is checkpointed to durable storage.
Controller sends deal summary via email/Slack with approve/reject action links.
Operator reviews item details, inspection report, and valuation model in real-time.
Approval routes to Settlement. Rejection routes to END or renegotiation workflow.
A PostgreSQL or DynamoDB-backed checkpointer saves the full ArbitrageState at every node transition. If the system crashes mid-inspection, it resumes from the last checkpoint — no opportunity is lost.
Profits accumulate in USDC within YieldDeals (Delaware LLC), are off-ramped to fiat, then transferred via Airwallex to YieldBio (Irish LTD) — qualifying for Ireland's 35% R&D tax credit and compounding the biotech investment.
This cross-border structure requires full compliance with US and Irish tax law, FinCEN reporting requirements, and Airwallex's AML/KYC framework. Legal and tax counsel in both jurisdictions must validate the structure prior to operationalization. The Airwallex platform provides built-in compliance tooling for cross-border transfers.
