Sixfold Raises $30 Million in Series B Funding Led by Brewer Lane

Sixfold just closed a $30M Series B, and the quiet part is the loudest. Insurance underwriting has spent decades swimming through PDFs, emails, half structured data, and institutional memory held together by caffeine and experience. Sixfold decided that if the work is already being done 6 different ways, maybe the answer is to fold it into one intelligent system that actually understands risk instead of just counting it.

This raise was led by Brewer Lane, with Guidewire stepping in as a strategic investor, and continued conviction from Bessemer Venture Partners and Salesforce Ventures. Capital like this does not show up for science projects. It shows up when the market has kicked the tires, checked the math, and realized the product does not blink when reality gets messy.

Alex Schmelkin, CEO, has been around insurance long enough to know where the bodies are buried and which processes never aged well. Jane Tran, COO, brings operational clarity sharpened by years inside global financial institutions where precision is survival, not a buzzword. Brian Moseley, CTO, has spent decades building platforms that developers actually trust, including scaling developer experience at American Express for 10,000+ engineers. That combination matters because underwriting is not theory. It is pressure, volume, accountability, and consequence.

Sixfold’s AI underwriter is already live across global carriers representing $265B in gross written premium, processing 1M+ submissions across 40+ lines of business. Adoption sits at 89% because underwriters do not have time for tools that require belief. They need tools that work inside existing workflows, respect underwriting judgment, and return time without stealing control.

Customers like Zurich North America, Skyward Specialty, AXIS Capital, Guardian, Generali GC&C, and BTIS are not experimenting. They are scaling. Implementations measured in weeks, not quarters. Hours saved per submission that compound into strategic focus instead of operational drag. That is the difference between automation theater and applied intelligence.

There is a reason this company is called Sixfold. Underwriting is about pattern recognition, context, and consequence, multiplied across portfolios. Fold the data, the rules, the judgment, the documentation, the compliance, and the decision into a system that can explain itself, and suddenly risk moves faster without getting sloppy.

This round fuels deeper autonomous underwriting, expanded research and engineering, and global growth across North America, Europe, Latin America, and Australia. The bigger signal is not the money. It is that insurers are trusting software to think with them, not instead of them, and Sixfold is earning that trust one decision at a time.
