Exclusive: Sixfold launches AI underwriting agent with straight-through quote and bind capability. By James Thaler Published: Fri 12 Jun 2026 Insurtech Sixfold is launching the AI Underwriter, an agent that learns an individual carrier's book and appetite, recommends the next action on each submission and can be configured to take cases straight through to quote-ready and bind-ready materials. The AI Underwriter will be available to P&C insurers from Monday, Sixfold confirmed in a statement to The Insurer. The agent feeds every decision an insurer's underwriters make back into that carrier's deployment, building what Sixfold describes as institutional memory that existing data ingestion, policy and workbench systems have not been built to capture. Each insurer's book is walled off, and one carrier's data is never used to train another's system. Each carrier weighs how much of the work the agent handles autonomously. When configured for straight-through processing, cases can be processed into quote-ready and bind-ready output for acceptance by a broker or client. The customer's underwriters provide direction, judgment and oversight, remaining accountable for how the agent is governed. Sixfold's customers represent $270 billion in gross written premium and include Skyward Specialty, Zurich Insurance, Generali Global Corporate & Commercial, Guardian, Axis and New York Life. The company has processed more than 1.5 million submissions across more than 50 lines of business since 2023. Sixfold said its customers have historically seen processing times improve by between 50% and 97% and hit ratios rise by 15% or more, with gross written premium per underwriter climbing by up to 30%, gains the company chalks up to its platform. The insurtech also reported underwriting adoption rates of 90% or higher, measured as actual users against expected users. Founder and CEO Alex Schmelkin said the product was built around what underwriters need at the moment a submission arrives, rather than documents bouncing between systems or static dashboards. "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," Schmelkin said. "Data ingestion and workflow solutions are trying to heal the symptoms of inefficient underwriting without affecting the cause. "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." When a submission comes in, the agent extracts and cleans the data, identifies missing information, evaluates appetite and portfolio fit and draws on what it has learned about the broker and risk class before producing a recommendation, explaining its rationale and suggesting a next step. The system is built around what Sixfold calls its underwriting brain, developed over three years alongside some of the world's largest insurers. The underwriting brain arrives trained on the standards behind professional underwriting credentials, underwriter reasoning patterns and a curated ground truth library, helping it work across lines of business and industries. A select group of insurers worked with the agent on live submissions ahead of the launch, with Sixfold reporting that it performed the majority of the underwriting analysis required to evaluate submissions within Skyward Specialty's E&S brokerage property business. Its responsible AI program was built from the bottom up, spanning governance controls and regulatory engagement, so that every deployment begins with trust from carrier risk and compliance teams, the company said. John Burkhart, Skyward Specialty's president of U.S. property and casualty, said the carrier is incorporating the agent into its bionic underwriting strategy as it looks for partners that can scale alongside the business and free underwriters to focus on what they do best. "We are equipping our underwriters with richer context that enhances their decision-making while keeping human expertise firmly at the center of the process," Burkhart said. Matthew Richardson, global head of operations and IT at Generali GC&C, said the product is built alongside underwriters, shaped by how the job works in practice and fast enough to change quoting timelines. "Sixfold helps us quote risks in minutes instead of days or in some cases weeks," he said. Sixfold raised $30 million in Series B funding in January. The round was led by Brewer Lane and included strategic investment from Guidewire, alongside existing backers Bessemer Venture Partners and Salesforce Ventures, as The Insurer previously reported. The raise, which funded development of the AI Underwriter, took the New York-based company's total funding to more than $50 million, following a $15 million Series A led by Salesforce Ventures in 2024. The launch adds to a wave of efforts to embed AI directly inside carrier underwriting operations, where submissions still move through a maze of legacy systems and manual workflows. Schmelkin co-founded Sixfold in 2023 with chief operating officer Jane Tran and chief technology officer Brian Moseley, with the company's wider platform supporting both P&C and life and health underwriting across North America, South America, the UK, Europe and Australia.

How is Sixfold's Series B round fuelling generative AI? The insurtech specialist Sixfold has raised US$30m in a Series B funding round led by Brewer Lane to accelerate the development of its generative AI underwriting technology. This investment round included strategic participation from Guidewire alongside continued backing from existing investors Bessemer Venture Partners and Salesforce Ventures. The capital injection is earmarked for the creation of what the company describes as the AI Underwriter which functions as a digital brain capable of managing end-to-end underwriting tasks autonomously. Sixfold's technology is designed to improve the speed and consistency of decision-making for carriers while allowing human professionals to pivot toward more strategic portfolio management. Alex Schmelkin, Founder and CEO of Sixfold says: "The underwriting role is being rebuilt from scratch. "InsurTech Digital is creating a future where underwriting operations completely run on Sixfold and strategy is run by people. "We're redefining what it means to be an underwriter." By expanding its research and engineering teams the firm aims to enhance its autonomous agents and broaden its data integration capabilities to reduce the time to value for new clients. The company plans to scale its commercial operations to meet rising demand across North America and Europe while establishing a stronger presence in Latin America and Australia. Integration with existing policy systems. A primary driver of the platform's adoption is its ability to integrate directly into the workbenches and policy administration systems already used by insurance professionals. This integration allows for rapid implementation without forcing teams to alter their established workflows or learn entirely new software environments. Jane Tran, Co-founder and COO of Sixfold notes: "There's a clear split forming in the industry. "To win business, you need speed and selectivity to quote quickly and write profitable risks. "To retain talent, you need to give time back to underwriters to focus on strategy. "Sixfold delivers both, and that competitive advantage increasingly shows up in combined ratio performance." Impact on the insurance combined ratio. As the industry faces increasing pressure on margins the efficiency gains provided by AI are becoming a key differentiator for global carriers. The Sixfold AI underwriting solution has already processed more than 1 million submissions across 40 different lines of business for major global entities. These insurers represent a combined US$265bn in gross written premium and include names such as Zurich North America and Generali GC&C. At Skyward Specialty the deployment of the platform across 11 teams resulted in a 35% reduction in quote response times. Zurich North America implemented the system for its middle market team of 200 underwriters and reported saving up to two hours on every submission processed. The software helps identify risks that match a carrier's specific appetite while flagging potential issues that require human intervention. Jay Grayson, Vice President of Corporate Development and New Ventures at Guidewire notes: "Underwriting remains one of the most critical and complex functions in P&C insurance. "Sixfold's approach tackles that complexity and delivers meaningful value to insurance carriers by applying agentic AI to key underwriting processes." By streamlining the ingestion of unstructured data the platform removes the manual burden of data entry that has historically slowed down the commercial insurance sector. Company portals.
