Intuit VP Details Two AI Rebuilds in Four Months
Intuit rebuilt its AI agent architecture twice in four months due to complexity and error issues.

Intuit was an early pioneer in the usage of agentic AI, but its path to success has hardly been a straight line. At VB Transform 2026, Intuit VP of AI Nhung Ho described how the company rebuilt its agent architecture twice in the span of about four months, first moving from a fleet of specialist agents to a central orchestration layer, then abandoning that layer for a skills and tools based system once the orchestrator itself started failing under its own complexity. The full second rebuild took 60 days, with a first working version in under 20.
The failure mode that forced the second rewrite was specific. Agents in the orchestrated system passed results to each other in natural language, and each handoff lost context the next agent needed to act correctly. "If you have 10 agents and they all are passing to each other, every time that pass happens, error compounds," Ho said.
Why the orchestration layer broke down Ho said the original push toward specialist agents came from a straightforward customer complaint. A fleet of capable agents is still something a customer has to manage, deciding which agent to use for which task. Intuit's answer was a system that could take a task and route it internally, without asking the customer to pick an agent themselves.
That orchestration layer held up for about three months, which Ho described only half joking as roughly a year in the compressed timeline of agent development in 2026. It broke for a structural reason rather than a capacity one. Passing outcomes between agents in natural language meant each downstream agent had to infer how the upstream agent reached its conclusion, and that inference degraded with each additional hop.
A ten agent chain did not fail occasionally, it compounded errors by design. That diagnosis is what sent Intuit back to a skills and tools architecture. The 60-day rebuild, and what it took to get engineering buy-in Rebuilding a production agent system in 60 days required more than an architectural decision.
Ho said the harder problem was internal, convincing both leadership and the engineers who had built the original agents that scrapping recent work was the right call. The pitch to leadership relied on evidence rather than argument. Ho's team built a demo of the new architecture using real customer queries pulled from production, then showed it performing better than the existing system on the same tasks.
"The best proof, at least my belief, is what are customers trying to do? And whatever system you build needs to address those problems," Ho said. Winning over engineering required a different case.
