Opportunity
Commercial property underwriters at large carriers are losing millions from mispriced flood and wildfire policies because their risk data is updated only annually and lacks building-level precision. With climate-driven losses surging—wildfire losses exceeded $10B and flood losses $5B in 2023—traditional models have become dangerously outdated. CorePeril delivers daily, per-building risk scores via satellite imagery and IoT streams, enabling underwriters to price accurately and cut loss ratios by 5-10% within 12 months.

Who Pays
Commercial insurance underwriters at large carriers specializing in property, casualty, and specialty lines, particularly those dealing with wildfire and flood exposure.
Painful Problem
A commercial property underwriter at a large carrier cannot access granular, real-time flood or wildfire risk for a specific commercial building because available data sources are either too coarse or updated only annually. This forces reliance on outdated risk models, leading to underpriced policies that generate unexpected loss ratios and erode underwriting profit.
Why Now
Climate change is accelerating wildfire and flood frequency, exposing the inadequacy of annual model updates. In 2023, US wildfire losses exceeded $10B and flood losses $5B. Carriers face pressure from regulators and rating agencies to improve risk selection. The cost and availability of satellite imagery and IoT sensors have dropped, making real-time risk feasible.

What It Does
A SaaS platform that ingests satellite imagery, IoT sensor feeds (e.g., soil moisture, weather stations), and public records to deliver daily-updated flood and wildfire risk scores at the individual building level. Using computer vision and damage assessment models, it flags properties with elevated risk due to recent vegetation changes, construction, or environmental shifts. Underwriters see an interactive map with per-building risk breakdowns, trend alerts, and recommended premium adjustments, integrated into their existing underwriting workflow via API or plugin.
How It Creates Value
Reduce loss ratios by 5–10% on wildfire/flood-exposed books within 12 months by enabling underwriters to price policies based on current, not annual, risk data, eliminating the information asymmetry that leads to underpricing.
Proof In The Product
- One-click property risk snapshot: underwriter pastes an address and sees a real-time risk score with breakdown by peril, trend arrow, and comparable policies.
- Alert dashboard: notifies underwriter when a policy in their portfolio crosses a risk threshold due to environmental changes.
- What-if pricing slider: adjusts premium based on risk score and shows impact on loss ratio over a 10-year horizon using historical claims data.
Why This Domain Fits
'CorePeril' directly communicates the product's focus on the central risk (peril) facing underwriters—wildfire and flood—and positions it as the essential data source for core underwriting decisions. The name is short, memorable, and implies foundational reliability, which resonates with risk-averse insurance buyers.
First Customer Profile
A regional commercial lines carrier (e.g., a super-regional like Auto-Owners or Cincinnati Insurance) with $2B–$10B in premium, a property-heavy book in the West/Southeast, and a recent loss ratio spike from wildfire/flood claims. The champion is the VP of Underwriting or Chief Risk Officer, who already spends $100K+ annually on outdated risk data.
A fundable idea also needs a path to revenue, distribution, and defensibility.
Economic Engine
Subscription fee based on the number of properties in the underwriter's portfolio (e.g., $0.50–$1.00 per property per month) plus a per-policy fee of $5–$10 when a policy is bound using CorePeril data. For a mid-size carrier insuring 500,000 commercial properties, annual ACV could reach $3–$6M. Gross margins >80% due to low marginal cost of data processing.
Why It Wins
Unlike traditional cat models (e.g., RMS, AIR) that update annually and rely on historical averages, CorePeril uses real-time environmental data streams and computer vision to provide a dynamic risk score that changes with conditions. Competitors like HazardHub offer static hazard layers, but lack the real-time ingestion and per-building precision for commercial properties. CorePeril is purpose-built for commercial underwriting, not consumer insurance.
Pricing Assumptions
ACV: $50K–$200K per carrier account based on portfolio size. Per-policy fee adds 10–20% ARPU. Gross margin >80% from cloud compute and data licensing. Expansion path: add hail, wind, and storm surge perils over time, increasing ARPU 3x.
Market Size
The global commercial insurance market is ~$1.2T (2025). Large carriers account for ~67% of premiums. A conservative estimate: 10,000 commercial property underwriters in the US alone, each responsible for $50M–$200M in premium. If CorePeril captures 20% of them at $5K/underwriter/year, that's $10M ARR from the US. Expanding to flood and wildfire specialty lines globally, TAM exceeds $500M. (Source: imarcgroup.com market size estimate)
Market Wedge
Start with commercial properties in the Wildland-Urban Interface (WUI) and FEMA-designated flood zones, where mispricing is most acute and underwriters are actively seeking better data. Target 10–20 carriers with large California, Florida, and Colorado books. These underwriters already budget for cat model subscriptions ($50K–$200K/year) and are motivated by recent wildfire losses (2017–2024).
Buyer & Sales Motion
Economic buyer: VP of Underwriting or Chief Risk Officer. Champion: Senior Property Underwriter frustrated with manual data gathering. Procurement hurdles include cybersecurity review and integration with legacy systems (Guidewire, Duck Creek). Sales cycle: 6–9 months. Pilot: free 30-day trial on a 1,000-property subset with a clear loss-ratio improvement metric. Proof-of-concept with 3–5 early adopters before scaling.
Competition
Direct: HazardHub, Guidewire Hazard Risk, RMS, AIR. These offer static, annual-update models. CorePeril wins on timeliness and granularity. Indirect: in-house analytics teams building spreadsheets. CorePeril replaces manual effort. Risk: incumbents may add real-time features, but their legacy architecture makes rapid iteration hard.
Distribution
Direct sales team of 3–5 former underwriters who speak the language. Partner with managing general agents (MGAs) who bundle CorePeril with their binding authority. Also, integrate with insurance platform ecosystems like Guidewire Marketplace and Verisk's underwriting tools. Use sponsored content in trade publications (e.g., Insurance Journal) and attend the PCI (Property Casualty Insurers) annual conference.
Moat
1) Proprietary data ingestion and computer vision models trained on commercial building characteristics (not residential), requiring specialized labeled data. 2) Network effect: every policy bound using CorePeril generates a claims feedback loop that refines risk models for all users. 3) Integration stickiness: once embedded in underwriting workflows via API, switching costs are high.
90-Day MVP
90-day MVP: a web app that shows a heatmap of wildfire/flood risk for commercial properties in California using publicly available satellite data and weather feeds. Allow underwriters to search by address and see a risk score (1–100) with three factors: vegetation proximity, slope, and historical fire patterns. Integrate with a single carrier's legacy system via CSV upload. No real-time updates yet—train a model on historical data and update weekly.
Finally, the diligence layer shows what still needs to be proven before this becomes more than a promising concept.
Validation Plan
- Interview 20 commercial property underwriters from 10 carriers to validate pain points and willingness to pay $5K+/year.
- Run a pilot with 2 carriers: provide free risk scores for 500 properties each, measure time saved and number of pricing adjustments made.
- Track conversion from free pilot to paid subscription; target 30% conversion within 3 months.
- Publish a whitepaper on 'Real-Time Wildfire Risk and Underwriting Profit' to generate inbound leads.
Key Risks
- Integration challenges with legacy systems: mitigate by offering simple CSV/API integration first, then building deep connectors for Guidewire and Duck Creek.
- Data accuracy: mitigate by using multiple data sources and ground-truth validation via partnerships with local fire departments.
- Carrier inertia to change workflows: mitigate by demonstrating clear ROI in pilot, targeting carriers already reeling from loss ratio spikes.
Fundability Verdict
Venture-scale opportunity with clear path to $10M+ ARR. Hardest assumption: that carriers will trust and integrate a new real-time data source into core underwriting. Must prove accuracy and ROI in a pilot before scaling. If successful, defensibility through data network effects and integration stickiness makes this a potential acquisition target by Guidewire, Verisk, or a reinsurance broker.
