Working in enterprise tech - an industry that has notoriously struggled to stay on the cutting edge - I never needed much convincing that AI would one day unlock massive opportunity. While we are nowhere close to meaningful adoption of AI, that’s where we’re headed.

The first wave of generative AI has been horizontal with the release of GPT-4, Anthropic, Bard, and others. But the next wave will be vertical, marrying the summarization and reasoning superpowers of the LLMs with specially-trained models and industry expertise.

This is why today, I’m excited to announce the launch of Sixfold, the first generative artificial intelligence trained to solve the hardest problems in the insurance industry.

With $6.5 million in seed backing from Bessemer Venture Partners and Crystal Venture Partners, and leadership with decades of insurance experience, Sixfold is poised to rapidly transform how the insurance industry thinks about and uses AI.

To start, Sixfold Gen AI will focus on one of the most intractable challenges in insurance: the inefficiency of underwriting.

Underwriting is an art form, requiring human-level pattern recognition to capture all of the things that go into understanding a complex risk. For years, insurers have struggled to extract clear rules and standards for assessing risk because there has simply been too much information. Insurance carriers have a “front-door problem”: because of how manual and time-intensive the underwriting process is, insurers can’t provide quotes on all of the opportunities that come their way.

A smart underwriting platform like you’ve never seen before.

Prior attempts at AI in insurance haven’t gained much traction because they took a “black box” approach and thought they knew better than the underwriters. These failed attempts need way too much data and haven’t produced consistent results. Instead, we’ve trained generative AI models to "understand" all of this information and assist humans with the manual assessment. With the Sixfold Assistant, underwriters will be able to quickly evaluate and rate all submissions, thus improving underwriters’ capacity as well as the accuracy and traceability of their decisions.

Today, the Sixfold Assistant is best positioned to eliminate a lot of the “grunt work” that underwriters deal with on a daily basis: tracking down information from third parties, poring through thousands of pages of documents, and making sense of unstructured data. Sixfold will serve as a co-pilot to underwriters, plugging into existing technology so insurers don’t need to overhaul legacy systems in order to take advantage of Sixfold’s capabilities.

We’re thrilled to be launching with our customer BTIS, the commercial insurance provider focused on the construction and building trades industry. Sixfold will be an important tool for BTIS underwriters to improve the speed and accuracy of their underwriting efforts. Sixfold will ultimately make BTIS more competitive by allowing its underwriters to spend less time poring over data and more time issuing policies to its customers.

Sixfold is partnering at launch with BuildZoom, the leading provider of contractor profile data, property building permit data and contractor sourcing services. Sixfold will also expand its partner ecosystem to include consulting and advisory firms, cloud providers, risk and prior loss providers and medical records providers.

Sixfold’s initial focus will be on the commercial property & casualty and life insurance sectors, with plans to expand across the entire insurance industry, going after the over $100 billion spent annually in the US to underwrite insurance.

I’m particularly excited to launch Sixfold because of who I’m doing it with.

Our founding team is made up of former founders and operators, with deep experience in highly-regulated industries, including decades in insurance. Jane Tran is our COO and co-founder. Jane and I spent years working together as founding team members at Unqork, the $2 billion enterprise no-code platform. Our CTO and co-founder Brian Moseley, joins us from American Express where he was Head of Developer Experience.

Let’s rewrite the rules of insurance together!

This announcement was originally posted on LinkedIn

No one became an underwriter because they love writing case notes. But that’s where a huge amount of time goes today. Referral notes, peer review memos, audit documentation, written and rewritten, case after case.

At multiple steps in the process, underwriters need to carefully document the risk story manually.

  • A single case can take an hour, often several hours, to document.
  • Underwriters are doing this work while balancing dozens of other tasks: reviewing new submissions, responding to brokers, preparing quotes, and managing existing accounts.
  • Multiply that across a typical team handling hundreds of submissions each week. The result is thousands of hours spent each year on documentation alone.

And the real costs for insurers go beyond time.

  1. Quotes go out slower to brokers and clients in markets where speed wins deals.
  2. Audit and compliance risks increase when documentation is inconsistent.
  3. When experienced underwriters leave, so does the knowledge of how to capture the right details in the risk stories.

Documentation is needed to make smart underwriting decisions and meet compliance standards. The question is: how do we get it without slowing teams down?

80% Automation, 20% Judgment.

Sixfold’s Narratives feature automates the repetitive parts of this process and standardizes how risk is communicated across the organization. It automatically generates risk narratives that match each insurer’s tone and format, while giving underwriters the flexibility to apply their own judgment where it matters.

[Shirley video explaining the feature]

Sixfold’s Narratives are built to:

  • Align with the insurer’s unique risk appetite
  • Surface key facts and risk insights that matter most
  • Adhere to required documentation standards and formats

On average, underwriters save more than 90 minutes per case with this capability. For a 10-person team handling 200 cases per week, that adds up to over 20,000 hours saved every year, time they can spend underwriting, not writing.

“Think of all the documents you have to create for administrative purposes, maybe it’s a referral summary, maybe an account summary attached to a submission after a decision. Anything that requires you to synthesize the risk overall.

Sixfold is doing 80% of that for you: bringing together all the facts. Then the underwriter just adds the last 20%, the judgment call.”

-   Laurence, Head of Customers and Partnerships

Proven with Zurich’s North America Team

Narratives were developed and validated through the Global Zurich Insurance Innovation Championship.

Over a 6-week sprint with Zurich’s North America Middle Market team, Sixfold:

  • Partnered with 16 underwriters and was used in 80%+ of their live submissions
  • Processed nearly 4,000 pages of submission and web data
  • Achieved 90 minutes time savings per submission on average

Sixfold was mentioned as a key driver in Zurich’s effort on capitalizing on new technology to improve accuracy and efficiency in underwriting process at Zurich’s Investor Day 2024

One Tool = Multiple Use Cases

The summarization and customization capability of this feature supports a variety of steps in the underwriting workflow, from intake through to decision documentation.

Use Case
Current Process
With Narratives
Quoting
Currently, risk factors are pulled together manually to decide if a case should be quoted.
Automatically summarizes key risk drivers upfront, providing a clear snapshot to prioritize cases faster.
Peer Reviews
Peer reviews are slowed by unstructured summaries; reviewers often have to go back to source documents.
Risk factors and case notes are presented clearly and consistently.
Referrals
Referral memos vary between underwriters; approvers often have to sort through inconsistent write-ups to understand the case.
Consistent case summaries make it easier for approvers to see the full risk story and sign off faster.
Decision Documentation
Underwriting rationale is often recorded unevenly; teams spend time cleaning up notes when preparing for audits.
A standardized record of underwriting rationale is created automatically, ready for audit without extra effort.
Business Impact
Faster decisions on which risks to quote.
More consistent risk appetite application and faster reviews.
Faster referral decisions.
Lower compliance risk and faster audit prep.

AI That Actually Gets Used

The Narratives feature is a great starting point for insurers looking to bring AI into underwriting workflows today.

It takes the repetitive parts of the job off underwriters’ hands without requiring them to change how they already work. It simply gives them back more time to focus on the parts of underwriting they enjoy.

“I already have a picture of this risk in 20 seconds instead of formulating it on my own.”[3] [4] [5]

When underwriters experience that impact immediately, with fewer hours spent writing up cases and fewer rounds of revisions, adoption happens easily. AI becomes part of the flow of work because it genuinely makes the day-to-day tasks so much easier.
