Sixfold, a company focused on generative AI for insurance risk analysis, has secured $30 mn in Series B funding to expand its AI-driven underwriting platform.
Brewer Lane led the round, with strategic backing from Guidewire and continued participation from Bessemer Venture Partners and Salesforce Ventures.
The capital will advance development of Sixfold’s AI Underwriter, built around autonomous agents designed to support end-to-end underwriting workflows.
The platform targets speed, consistency, and improved decision quality, shifting underwriters toward portfolio oversight, appetite refinement, and emerging risk evaluation rather than manual intake work.
Founder and CEO Alex Schmelkin said underwriting operations should run on software while strategic judgement remains human-led.
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.

According to Beinsure analysts, carriers pursuing expense ratio compression increasingly focus on submission triage and decision support as leverage points inside P&C operations.
Sixfold plans to expand research and engineering teams to deepen autonomous agent capabilities, integrate broader datasets, and improve portfolio visibility.
The company will also scale commercial operations across North America, Europe, Latin America, and Australia.
The system connects with existing underwriting workbenches and policy administration platforms, allowing deployment without workflow disruption.
Rapid implementation has supported adoption among larger carriers seeking measurable impact without system replacement.
- Guidewire’s Jay Grayson said underwriting remains complex within P&C insurance, and agentic AI applied to decision workflows creates tangible value.
- Jane Tran, Sixfold’s co-founder and COO, said carriers now face pressure to quote faster while maintaining selectivity and underwriting discipline. She argued performance advantages increasingly show up in combined ratio outcomes.
- Brewer Lane founder John Kim cited market due diligence and customer feedback as drivers behind the investment decision, pointing to underwriting expertise as a differentiator.
In 2024, Sixfold, the insurtech empowering underwriters with a generative AI solution for end-to-end risk analysis, has raised $15 mn in Series A funding.
Sixfold, using its innovative patent-pending technology, secured investment led by Salesforce Ventures, with contributions from Scale Venture Partners and previous investors including Bessemer Venture Partners and Crystal Venture Partners.
The investment will support the expansion of Sixfold’s team of AI/ML engineers, enhance product capabilities, and accelerate research and development efforts.
This funding will facilitate Sixfold’s market expansion from North America to the UK and the European Union.
Sixfold reports its AI solutions have processed more than one million submissions across over 40 lines of business, representing $265 bn in gross written premium.
Clients include Zurich North America, Guardian, Generali GC&C, and Skyward Specialty. Skyward Specialty deployed the platform across 11 underwriting teams and reduced quote response times by an average of 35%.
Zurich North America implemented Sixfold for its middle market unit of more than 200 underwriters, saving up to two hours per submission.
We think productivity gains at that scale directly influence underwriting margin and talent retention.
In 2025, Sixfold has launched a new feature called Discrepancy Scan. The tool automates the identification of inconsistencies in life and disability insurance applications by comparing applicant-submitted data with medical records.
It flags mismatches such as undisclosed medications, helping underwriters identify issues that could lead to errors, delays, or fraud.
This release aligns with the broader trend of AI adoption in insurance, where technology is being used to improve risk assessment, reduce manual effort, and limit fraud. Insurance fraud costs the industry several bn dollars annually.
