Sixfold Secures $30M Series B Funding to Scale Autonomous AI for Insurance Underwriting

Sixfold, a pioneering AI-driven insurtech specializing in underwriting automation, has successfully raised $30 million in a Series B funding round to accelerate the global deployment of its autonomous AI solutions for the insurance industry.

The round was led by Brewer Lane Ventures, with strategic investment from Guidewire Software and continued participation from Bessemer Venture Partners and Salesforce Ventures — reaffirming strong investor confidence in the company’s technology and growth trajectory.

Transforming Underwriting Through Autonomous AI

Over the past three years, Sixfold has demonstrated that autonomous AI can operate effectively in real underwriting environments, enabling insurers to dramatically enhance decision speed and quality while reducing manual workload.

Underwriters at several global insurance carriers — including Zurich Insurance, Skyward Specialty Insurance, Generali Global Corporate & Commercial, and Mosaic Insurance — now incorporate Sixfold into daily workflows. These customers have reported:

• Faster and more consistent quoting,
• Smarter, appetite-aligned risk selection, and
• More satisfied underwriting teams due to reduced administrative burden.

According to Sixfold’s team, users benefit from AI insights that run seamlessly alongside existing workbenches and systems, meaning no disruption to established processes while achieving measurable business outcomes.

Strategic Expansion & Future Vision

With the new capital infusion, Sixfold plans to scale its research and engineering teams to further enhance its AI Underwriter platform, expand commercial operations, and deepen global adoption across North America, Europe, Latin America, and Australasia.

CEO Alex Schmelkin highlighted that the company views underwriting not just as a process to automate but as a strategic function to elevate, allowing human professionals to focus on portfolio performance, risk strategy, and business growth while AI handles repetitive and data-intensive tasks.

Industry Impact

The funding comes at a time when the insurance sector is aggressively pursuing digital transformation, and underwriters face pressure to deliver faster decisions without compromising risk quality. Sixfold’s autonomous AI positions carriers to tap into competitive advantages, including improved throughput, decision consistency, and workforce productivity.
