Bill Martin has a message for the InsurTech startup ecosystem: legacy carriers aren’t behind the curve. They are the curve.
In a recent episode of the Dig-In Podcast, Martin—president and CEO of Plymouth Rock Home Assurance, a Northeast insurer writing more than $2.3 billion in premiums—laid out a detailed case for why traditional carriers hold structural innovation advantages that most startups simply cannot replicate.
The timing matters. The InsurTech sector is entering what many analysts call a maturation phase. CB Insights reported that InsurTech M&A exits reached a three-year high of 74 deals in 2025, even as deal counts shifted toward fewer, larger rounds concentrated in AI-first solutions. The narrative is changing from disruption to integration—and Martin’s argument explains why.
The Structural Advantage Legacy Carriers Won’t Admit
Martin’s central thesis is deceptively simple: legacy carriers can deploy one team to solve one customer problem without rebuilding payroll, legal, compliance, or shared services from scratch. Startups, by contrast, burn capital and management attention on infrastructure that has nothing to do with product delivery.
This isn’t abstract. Plymouth Rock recently partnered with NWN to integrate voice analytics and generative AI into its contact center operations—a targeted deployment that layers onto existing infrastructure rather than requiring a ground-up build. That’s the modular approach Martin champions: build systems where individual components can be swapped without destabilizing the whole.
Martin invoked Frederick Brooks’ classic “The Mythical Man-Month” to illustrate the point. A developer at a large carrier managing interconnected systems across multiple states and product lines is doing fundamentally more complex work than a startup engineer building for a single product in a single state. Comparing their productivity apples-to-apples is, as Martin put it, “mythical.”
Where InsurTech Startups Keep Stumbling
Martin didn’t mince words on startup economics. His critique centers on three structural weaknesses that funding rounds tend to mask:
- Growth by underpricing: “Just about anybody can grow rapidly by losing money in this business. We reward a lot of companies that are underpriced.” This echoes the broader sector correction—many InsurTech full-stack carriers celebrated scale metrics while hemorrhaging cash on combined ratios above 120%.
- The agent pivot: Martin noted one prominent InsurTech that publicly declared the death of agents—then quietly adopted an agency model within five years. This pattern of publicly rejecting, then privately adopting, incumbent distribution strategies suggests the disruption thesis was always more marketing than reality.
- Profit margin stacking: Assembling 50 vendor solutions means layering 50 profit margins into the cost structure. “You can’t add together 50 vendor profit margins and come up with a profitable company,” Martin argued. This math explains why the unbundled InsurTech model faces a ceiling that vertically integrated carriers don’t.
The Commoditization Trap—And Who’s Falling Into It
Perhaps Martin’s most counterintuitive argument: large carriers are actually commoditizing themselves by buying off-the-shelf platforms that deliver identical customer experiences across competitors. When company A and company B run the same policy administration system, what differentiates them in the customer’s eyes? Nothing but price.
Martin’s answer is differentiated data strategy. Plymouth Rock, for example, negotiates for raw data sets and pre-rates its market before point of sale—rather than relying on transactional vendor scores that every competitor can buy. The approach is more expensive upfront but creates a pricing advantage competitors can’t copy by swiping a credit card with the same vendor.
This connects to a broader industry reality. According to a recent analysis, with up to 95% of AI pilots failing to scale, the carriers that extract value from technology aren’t the ones buying the shiniest tools—they’re the ones integrating selectively and building proprietary advantages.
The AI Opportunity Martin Actually Believes In
Martin is bullish on AI, but with a very specific framing. He compared AI to the California Gold Rush: the fortunes weren’t made by the miners but by the companies selling shovels, running banks, and building railroads. AI, in Martin’s view, is connective tissue—the infrastructure layer that enables mass customization across use cases.
He drew a sharp distinction between true AI and what he considers mislabeled capabilities. Machine learning, he argued, is “not artificial at all”—it’s structured, it’s been deployed for over 15 years, and calling it AI inflates expectations. The real breakthrough is in processing unstructured data at scale: consolidating inconsistent inspection formats across loan, real estate, insurance, and construction sources into a unified intelligence layer.
That said, Martin issued a warning that few industry leaders will publicly acknowledge: the insurance industry’s expense ratios haven’t materially improved despite 30 years of automation investment. The IT spend has simply replaced other costs. If AI follows the same pattern—expensive to deploy with savings that never reach the customer—the industry will be exactly where it started, just with newer hardware.
What This Means for the Market
For InsurTech founders: Martin’s analysis doesn’t dismiss startups—it reframes the winning strategy. InsurTechs that position for strategic acquisition rather than market displacement are playing the game correctly. Build something a legacy carrier would pay to own rather than something that tries to replace them.
For investors: The shift from disruption to integration is accelerating. CB Insights data showing InsurTech M&A exits at a three-year high in 2025 validates the thesis. Due diligence should focus less on “can this replace an incumbent?” and more on “will an incumbent pay to absorb this?”
For legacy carriers: The structural advantage is real, but only if it’s directed at customer-facing differentiation. Martin’s sharpest insight is that carriers keep pointing technology inward—optimizing operations—instead of outward at the customer experience. The winners in the next phase will be incumbents who use their structural advantages to deliver something customers will pay a premium for.
The Bottom Line
The InsurTech disruption narrative always assumed incumbents were standing still. They weren’t. They were processing complexity that startups didn’t yet understand—and now the market data is catching up to that reality. The question isn’t whether legacy carriers can innovate. It’s whether they’ll innovate for themselves or for their customers.
That distinction, as Martin suggests, is the only one that matters.
