Shipped This Week: Multi-Agent IC Pipeline

Five specialist AI agents (Underwriting, Market, Risk, Operations, IC) now collaborate to produce institutional-grade deal analysis in under 90 seconds. Live demo available.

This week we shipped the multi-agent pipeline that powers the Deal Analyzer.

The architecture is intentionally boring: five specialists, four running in parallel, one (IC) running sequentially as a reducer that consumes the others. Each agent has a strict JSON contract — the model is constrained to a typed output schema, and missing inputs return null rather than fabricated values. When the API key isn't configured, the orchestrator falls back to typed stubs so the rest of the platform keeps working.

What we wanted to avoid: an agentic system that fails opaquely, hallucinates specific facts, or produces inconsistent output formats. The cure is contract discipline — every agent is a function from inputs to a known JSON shape, and the orchestrator only trusts what the schema validates.

What this enables: an analyst can run a 48-unit multifamily deal end-to-end in 90 seconds and get back a draft IC memo with structured risk surfacing, market briefing, and a defensible recommendation. The analyst still owns the final judgment — the AI just produces the scaffolding faster than a human could.

Try it on a sample deal or run your own.
