Sixfold, an artificial intelligence platform for the insurance industry, has launched its AI Underwriter, an autonomous underwriting agent designed to evaluate submissions, learn carrier-specific appetite, and guide underwriters to a clear next action on every case.
The product is the outcome of a $30m Series B funding round closed in January and three years of development carried out alongside some of the world’s largest insurers.
The AI Underwriter is built to extract and clean incoming submission data, identify gaps, assess appetite and portfolio fit, and draw on what it has learned about a given broker and risk class before presenting a recommendation and a suggested next step to the underwriter.
At the core of the product is what Sixfold calls its Underwriting Brain, a shared foundation trained on professional underwriting credentials, reasoning patterns, and a curated ground truth library spanning multiple lines and industries. This foundation means carriers see value from the first day of deployment.
Beyond that, the system learns exclusively from each individual carrier’s own book, appetite, guidelines, and underwriter decisions. No carrier’s data is used to train another’s instance, meaning that after a year of operation each carrier accumulates institutional memory built entirely from its own business.
Where the earlier iteration of Sixfold’s technology focused on gathering and enriching submission data and flagging appetite fit, the AI Underwriter goes further by taking action on submissions and incorporating wider context including broker history, portfolio composition, and current book fit. When configured for straight-through processing, it produces quote and bind-ready materials.
The system integrates directly into the tools and systems carrier teams already use, which Sixfold says contributes to an adoption rate of 90% or higher across its customer base.
Sixfold founder and CEO Alex Schmelkin said, “What does a great underwriter actually need the moment they receive a submission? They don’t need a digitized version of the application, broker documents moved from their inbox to another system, or a dashboard with data that was current last week.
“Instead, our users told us that what they need is to understand the risk in the full context of their current book, the broker, and the guidelines, and to be presented with a clear next step. Right there, at the moment a decision is being made. That is what the AI Underwriter does.”
Skyward Specialty vice president E&S brokerage, property Melissa Butt said, “The AI Underwriter does not just summarize what you are looking at, it gives you a point of view and a clear path forward. For more junior underwriters it’s a powerful companion that gives them the perspectives of a more experienced underwriter and accelerates their development. Even veteran underwriters who are a little more skeptical of new technology, see the tool as an added layer of intelligence. Plus, the ability to fully examine a submission and make better, more confident decisions without even leaving the tool is a huge benefit. The entire team is excited to work with it.”
