Joao Wenzel of Citadel Securities told AI Engineer his team built agents to keep a living model of the company itself. Over two thirds of staff write code, he said, and leadership asked if the same systems could help set strategy. His answer is an institutional memory loop that runs update, age, observe, grade and correct.
RAG is not enough.
Wenzel showed a March 16 status check where retrieval called a project green from slides and Slack threads and missed the real risk. His team keeps a three year longitudinal record, so it knew a renamed project was still Project Northstar from people and goals. It also splits reported status from evidence, flagging one green slide as yellow over an open dependency, and those flagged greens turned yellow or red at twice the rate in backtests.
Anyone who has parsed a BizOps deck knows why this breaks. Unpack the PowerPoint XML and you argue about the hex code for green. Screenshot it for a vision model and it squints at a pasted dashboard to tell a 31 from an 81. Wenzel said the fix was inelegant but effective, use both, then track continuity because Slack from five days ago will contradict the deck.
Every fact gets a half life in his design. Half the delivery dates changed within two months over three years, he said, and 90 percent slipped later than first promised. Specialist agents now break down the collateral instead of one pass over the corpus, which more than doubled insightful updates, and humans correct the record in Slack or email where stakes are high. Contrast that with Spotlight.ai, which describes a revenue team world model that plugs into Claude, Gong and the CRM via MCP for forecasting and stakeholder mapping.
The payoff at Citadel Securities is a weekly read that starts where deck and evidence disagree, plus a context layer other agents can reuse for clients. The hard parts left are entity resolution across four systems with no canonical ID and asking the right person the right question at the right time. Start collecting traces now or your agent will keep calling watermelons green.
