$4 Billion in Reinsurance Premium, Zero to That in Five Years. That Growth Rate Should Have Been the Red Flag Itself.

This is the first of two conversations on the Vesttoo scandal, recorded the Sunday the story broke — everything discussed is explicitly sourced from public reporting (Meir Orbach at Calcalist, followed by Fiona Robertson and Farhin Lilywala at Insurance Insider), not inside information, and framed throughout as “hearsay” pending an official audit.

The core allegation: Vesttoo, an insurance-linked securities (ILS) marketplace, had posted letters of credit purportedly issued by China Construction Bank that turned out to be fraudulent. An investor attempting to collect on one such LOC through the bank’s New York branch was told the instrument didn’t exist and had never been authorized — a discovery with dramatic implications given that Vesttoo’s entire model depended on these instruments to collateralize the ILS investments flowing through its marketplace. Emilio Figueroa’s estimate at the time: the exposure could run as high as $1-4 billion in reinsurance premium backed by these instruments.

In Episode 102 of InsurTechTalk, Emilio and I worked through the corporate structure underneath Vesttoo’s ILS marketplace, how fronting companies actually function and where their real risk sits, and why a company growing from zero to $4 billion in reinsurance premium in five to six years should have triggered much deeper scrutiny before the fraud was discovered rather than after.

About Emilio Figueroa

Emilio Figueroa is CEO of Indemnity Lab, a strategy-as-a-service firm launched roughly three months before this recording, built around a think tank of 18-19 C-level insurance executives — experts across reinsurance, underwriting, claims, operations, and marketing. Indemnity Lab serves private equity and venture capital firms’ portfolio companies, analyzing their existing strategy (loss ratios, combined ratios, underwriting profitability) and recommending changes, aimed at Series C-and-later VC-backed companies and comparably mature PE portfolio companies. Emilio has spent 33 years in the insurance industry.

Why Indemnity Lab Exists

Emilio’s founding observation, drawn from years mentoring startups and MGAs directly: founders tend to absorb an advisor’s knowledge in the first roughly three years and then, in his words, believe “through osmosis” that they’ve extracted everything useful before moving to the next shiny mentor. Indemnity Lab’s structure addresses that by offering PE and VC firms a standing bench of deeply experienced, 30-plus-year insurance executives — his pitch: 19 senior executives for roughly the annual cost of a single full-time employee — brought in specifically to help fast-moving, technically sophisticated startups (his metaphor: companies that build agile ships but don’t necessarily know how to steer them) navigate the legacy mechanics of insurance economics that determine whether their underwriting is actually profitable.

What Vesttoo Actually Was, Structurally

This is the most useful part of the conversation for understanding why the fraud mattered as much as it did — Emilio walked through the corporate structure in detail, because the complexity itself is central to how the exposure accumulated.

• Vesttoo built an ILS marketplace — a platform connecting investors willing to take on reinsurance risk with reinsurance programs seeking capacity, layered with AI-driven predictive analytics for portfolio performance
• Because Vesttoo itself had no capital reserve to collateralize these investments directly, the model depended on letters of credit issued by banks to stand behind the risk
• To actually take on reinsurance risk, Vesttoo needed a genuine insurance vehicle — since it wasn’t licensed to sell insurance directly, it partnered with Corinthian Group (specifically Corinthian Re, out of Georgia) to create a reinsurance captive structure
• The resulting entity chain, as reported: a Bermuda holding company (issuing notes to ILS investors), an operating agreement with Osprey Re (owned by Corinthian), and Osprey Re Vesttoo IC — a segregated cell captive structure enabling protected/segregated cells for individual programs

Emilio’s framing of why companies build structures this elaborate at all: it’s the standard toolkit for alternative risk transfer — reinsurance captives, segregated cell structures, and fronting arrangements have existed since the 1950s-60s, developed specifically to let non-traditional players participate in hard markets where standard carrier capacity was scarce or overpriced. What Vesttoo built wasn’t conceptually novel — Emilio’s assessment: “creative,” not “innovative” — a scaled-up, more accessible version of the reinsurance sidecar model, aimed at a much broader base of participants than the structure traditionally served.

How Fronting Companies Actually Work, and Where the Risk Sits

Given how central fronting companies are to how insurtech MGAs get to market (a topic Emilio and I connected directly to the broader insurtech MGA boom starting roughly 2014-2015), Emilio broke down the economics precisely.

• Pure fronting (his example: State National) takes a flat fee — typically 3-7% — and carries no credit or underwriting risk itself, simply providing paper and capacity before passing the risk fully through to reinsurers
• Hybrid fronting companies — increasingly common in the insurtech era — actually retain a meaningful slice of risk themselves, commonly a 10-20% quota share position, plus sometimes an excess-of-loss layer above that, meaning they’re carrying genuine credit and underwriting exposure, not just collecting a service fee

Corinthian Re’s role in the Vesttoo structure functioned as the underwriter and portfolio manager — effectively acting as the reinsurer of record on the back end of programs that Vesttoo’s marketplace connected to investor capital.

The Growth Rate Itself Was the Warning Sign

Emilio’s sharpest structural critique, delivered before any fraud specifics were confirmed: Vesttoo grew from zero to roughly $4 billion in reinsurance premium under management in five to six years — a genuinely extreme growth trajectory for any financial services company, let alone one this structurally complex. His point wasn’t that fast growth is inherently suspicious, but that a company scaling that quickly needs correspondingly rigorous internal controls to ensure “all your ducks are in a row” — and that when a single domino falls in a company built this fast, without adequate compartmentalized controls, other dominoes tend to fall with it rather than being contained.

The Due Diligence Gap

Pushed on what specifically should have caught this earlier, Emilio’s answer centered on a distinction between financial due diligence (which most sophisticated investors do reasonably well — reviewing financials, expense reports, technology provenance) and genuinely deep regulatory and counterparty due diligence — specifically, standing panels where reinsurance partners, carrier partners, and banking relationships are directly and regularly verified face-to-face, not just documented on paper.

His specific critique: a proper financial banking panel — regular direct meetings between a company’s senior leadership and named individuals at its banking partners, specifically to discuss and verify instruments like letters of credit — appears to have been absent. That’s the exact mechanism that would have surfaced the fraudulent LOCs well before an investor discovered the problem by trying and failing to collect on one directly.

What Indemnity Lab Would and Wouldn’t Have Caught

I asked directly whether Indemnity Lab’s own service model would have flagged this kind of risk. Emilio was candid: Indemnity Lab doesn’t currently perform formal due diligence — its engagement model assumes a company has already been vetted to a reasonable degree (hence the Series C+ / established-program focus) and then works on strategic optimization: analyzing reinsurance contracts and structure, claims handling, underwriting filings, competitive positioning, and genuine total addressable market (as opposed to the inflated TAM claims many companies present). He noted, pointedly, that Vesttoo was reportedly mid-Series-D at the time the fraud came to light — exactly the kind of “established” company Indemnity Lab’s model would treat as already vetted, which is itself a useful data point about how far institutional-round status can diverge from genuine operational soundness.

Marketing Genius, Structural Substance: A Tangent Worth Keeping

In a moment of candor about the broader insurtech landscape, Emilio and I discussed Lemonade’s “instant claim payment” marketing and its “synthetic agent” framing — Emilio’s blunt read: brilliant marketing, full stop, but marketing doesn’t change the underlying economics. His example: relabeling what functions as a 16% interest cost as a “synthetication” fee doesn’t change what it actually is; it just makes it more palatable. His genuine frustration, expressed candidly: a company posting a 277% combined ratio “makes me angry, because it makes me look like a fool in this industry” — and his stated motivation for Indemnity Lab’s work is specifically closing that gap between marketing sophistication and underwriting fundamentals.

What Happens Next

Asked to forecast, Emilio’s read (again, explicitly speculative) anticipated the trajectory that later reporting largely confirmed: probable regulatory scrutiny increasing across the ILS space, likely criminal exposure for individuals directly involved if fraud is confirmed, and — his hoped-for outcome despite the damage — a genuine industry learning moment that raises the bar on counterparty due diligence going forward, even while conceding real short-term reputational damage to the ILS category broadly.

On downstream impact to policyholders specifically, Emilio was precise about where liability actually sits: regardless of what happens with reinsurance recovery, the fronting or writing carrier remains ultimately responsible for paying policyholder claims — reinsurance failure doesn’t relieve the primary carrier of that obligation, it just determines whether the carrier can recover anything from the reinsurance side afterward. At the time of recording, no reported instance yet existed of an actual policyholder losing coverage as a direct cascading result — the damage visible so far was contained to deal disruption (he cited one carrier partner forced to pause a pending sale process pending further diligence) rather than confirmed consumer-level loss.

Key Takeaways

• Vesttoo’s ILS marketplace depended on letters of credit it didn’t have the capital to back directly — a structural dependency that made counterparty verification of those instruments existential to the entire model, not a peripheral compliance detail
• The corporate structure (Bermuda holding company, Corinthian Re reinsurance partnership, segregated cell captive) wasn’t conceptually novel — it extended a decades-old alternative risk transfer toolkit to a much broader, faster-scaling base of participants
• Fronting companies range from pure fee-based paper providers (no credit risk) to hybrid structures retaining real quota share and excess-of-loss exposure — understanding which type you’re dealing with materially changes the counterparty risk profile
• A company scaling from zero to $4 billion in premium in five to six years needs correspondingly rigorous, compartmentalized internal controls — rapid growth without them means one failure risks cascading rather than being contained
• Genuine due diligence requires standing counterparty panels — direct, regular verification with banking and reinsurance partners — not just document review; that gap appears to be exactly what let fraudulent LOCs go undetected
• Regardless of reinsurance failure, the fronting or writing carrier remains ultimately liable to policyholders — reinsurance is a recovery mechanism for the carrier, not a substitute for the carrier’s own obligation
• Marketing sophistication and underwriting fundamentals are genuinely distinct, and a company can excel at one while badly failing the other — closing that gap was Emilio’s stated motivation for founding Indemnity Lab
