Sixfold
AI underwriting agent that reads insurance submissions and recommends risk decisions for P&C and life carriers.

Sixfold builds AI that reads incoming insurance submissions, extracts and cleans the underlying data, checks it against a carrier's stated risk appetite, and produces a recommendation with a rationale for a human underwriter to accept or override. Founded in New York in 2023 by Alex Schmelkin, Brian Moseley, and Jane Tran, the company built what it calls an Underwriting Brain — a base model trained on underwriting reasoning and a curated library of risk examples — that each carrier then fine-tunes into its own private instance using its own guidelines and historical decisions. The company has raised roughly $52 million across a Series A led by Salesforce Ventures and a $30 million Series B led by Brewer Lane with strategic backing from Guidewire. Customers span P&C and life & health insurers including Zurich, Generali, Guardian, and New York Life, representing a combined $270 billion in gross written premium under some level of Sixfold usage. In 2026 the company launched an AI Underwriter agent capable of taking straightforward submissions through to a quote- or bind-ready state, moving beyond decision support into more autonomous territory, which puts it in more direct competition with legacy underwriting workbenches from Guidewire and Duck Creek as well as newer AI-native rivals like Akur8.
