Sixfold, an artificial intelligence platform for the insurance industry, has unveiled its AI Underwriter, an underwriting agent designed to evaluate submissions, retain institutional knowledge, and guide underwriters toward their next best action on every case.
The launch follows a $30m Series B funding round completed in January, which was raised specifically to build the product. The AI Underwriter is now available to property and casualty (P&C) insurers, with the company stating it has been developed over three years of work alongside some of the world’s largest insurance carriers.
When a submission arrives, the tool extracts and cleans all relevant data, identifies any gaps, assesses appetite and portfolio fit, and draws on what it has learned about the broker and risk class in question. It then produces a recommendation alongside a rationale and a suggested next step for the underwriter. The system is also configurable for straight-through processing, in which case it produces quote and bind ready materials for a broker or customer to accept.
At the core of the product is what Sixfold calls its Underwriting Brain, a foundation pre-trained on professional underwriting credentials, reasoning patterns, and a curated ground truth library spanning multiple lines and industries. From there, each carrier builds its own separate instance. The system learns that carrier’s book, appetite, and guidelines, and every underwriter decision feeds back exclusively into that carrier’s version of the model. Sixfold has stated that one carrier’s data is never used to train another’s.
Prior to today’s launch, a group of insurers piloted the AI Underwriter on live submissions. At Skyward Specialty, early results indicated that the tool carried out the bulk of underwriting analysis required to evaluate submissions. The company also reports that underwriting adoption among its customers sits at 90% or above, measured as actual versus expected users.
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.”
