Sixfold, an AI underwriting InsurTech company focused on modernising insurance decision-making, has secured fresh capital as it looks to deepen its footprint with insurers around the world.
The New York-based firm has raised $30m in a Series B funding round led by Brewer Lane, with strategic backing from Guidewire.
Existing investors Bessemer Venture Partners and Salesforce Ventures also participated in the round, reaffirming their support for the company’s growth strategy.
Founded to address inefficiencies in insurance underwriting, Sixfold develops artificial intelligence designed to support property and casualty insurers. Its technology automates and augments underwriting workflows, helping insurers assess risk more quickly and consistently. By applying AI across large volumes of structured and unstructured data, the platform aims to improve decision quality while reducing manual effort for underwriting teams.
The newly raised capital will be used to develop what the company describes as its ‘AI Underwriter’, an autonomous system capable of handling end-to-end underwriting tasks. Sixfold plans to expand its research and engineering teams to accelerate product development, while also scaling its commercial operations to meet rising demand across North America, Europe, Latin America and Australia.
In addition to product development, Sixfold is focused on ensuring its technology integrates directly into existing underwriting tools, including workbenches and policy administration systems. This approach allows insurers to deploy the platform quickly without requiring underwriters to change established workflows, a factor that has supported adoption among large carriers.
The company says its AI solutions have already processed more than one million submissions across over 40 lines of business. These deployments support insurers representing a combined $265bn in gross written premium, including Zurich North America, Guardian, Generali GC&C and Skyward Specialty. According to Sixfold, Skyward Specialty has reduced quote response times by an average of 35%, while Zurich North America has reported savings of up to two hours per submission after rolling out the platform to more than 200 underwriters.
Sixfold founder and CEO Alex Schmelkin said, “The underwriting role is being rebuilt from scratch. We’re 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.”
Guidewire vice president of corporate development and new ventures Jay Grayson said, “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.”
Sixfold co-founder and COO Jane Tran said, “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.”
Brewer Lane founder John Kim said, “We did extensive due diligence across the market, talking with customers, prospects, and industry experts. Sixfold’s reputation stood out again and again, specifically around their deep expertise in underwriting. That level of market respect is rare; it speaks to the quality of the product and team they’ve built.”
