Underwriting on a closed loop. Live portfolio signal at the desk and at product configuration, in minutes. The chief actuary and the head of underwriting decide. The line underwriter sees the live picture.
Start a SprintCombined ratio is set in selection, months before the loss run lands. Every bound risk and every decline belongs in the appetite calculation by the next quote. Portfolio Lens connects product configuration, the underwriting desk, and the live picture of the book. Updates arrive within minutes. Bound risks feed the appetite. Declined-risk loss runs feed the calibration that issued the decline.
The context
The portfolio gap
The bound book is half the picture. It is a self-confirming sample, made up of risks the carrier said yes to. The appetite question lives in the deals the carrier said no to. Loss runs arrive with most commercial-line submissions. Today they are read once at decline and then discarded.McKinsey · From art to science: The future of underwriting
The pricing fact
Lloyd's priced minus 3.7% in 2025, the first negative move after seven years of strengthening. Reinsurance softening at 1/1/26 ran into double-digit risk-adjusted reductions on non-loss-impacted property catastrophe programs. Moody's had forecast a drop of roughly 15% for those renewals.Lloyd's Full-Year 2025 Results · Moody's Ratings · Guy Carpenter Portfolio discipline is the lever left.
Where speed misses
Faster intake leaves two gaps. One is upstream, in the appetite that triages each submission. The other is downstream, in the bound book that should inform the next quote. Both sit outside the intake step.
MGA channel scale

US MGA premium reached $114.1B in 2024, up 16% year-over-year. Non-affiliated MGAs are now 46.6% of the segment, surpassing affiliated for the first time. Delegated authority is where capacity providers need live appetite enforcement most.

−3.7 %
Lloyd's average pricing moved negative in 2025 after seven years of increases. Expense ratio rose 1.2 points to 35.6%. The pricing tailwind that masked portfolio drift through the hard market is gone.

The bound book tells you what you wrote. The declined submissions tell you what you should have written.
The math
What the lag costs
Between portfolio reviews, exposure drift accumulates. A class that surprised the book last quarter is still bound at quoted terms this quarter. The carrier learns from the loss run; the broker learns from the next quote. A live loop closes the gap.
Where intake stops
Better triage against a stale appetite still misses the concentration tail. Submission speed moves quote-to-bind. Portfolio discipline moves combined ratio. They are different metrics on different time horizons.
Where the loop adds value
Back-pressure on appetite catches the line that would have over-concentrated before it binds. Loss runs from declined submissions calibrate the appetite that did the declining. At most specialty carriers that is three to ten times the bound volume of training data. With rates falling, combined ratio moves on selection.
How the case is made
A back-test makes the case. Your own historical decisions are scored against what the loop would have surfaced. Same data, same point in time. The result is a measured comparison on your own book, favorable or not.
The Blueprint
Portfolio Lens sits above the existing data estate: PAS, underwriting workbench, and reinsurance ledger. The systems of record stay in place. Three layers above them watch the bound book, learn from the full submission flow, and surface the live picture back to the desk, the chief actuary, and the product team. Updates arrive within minutes.
Layer 03 · Surfaces
Line Underwriter
Underwriter Desk
Live appetite at the moment of quote. In-context concentration position. Broker-quality score alongside the submission.
Chief Underwriting Officer · Chief Actuary
Portfolio Cockpit
Live exposure, concentration drift, reserve development across line, geography, broker, and treaty. Comparative back-test artifact. Override log.
Product Team
Product Configuration
Wording, limits, and appetite rules configured per segment against the live picture of the book. Aggregation rules and reinsurance contracts in the same place.
Decisions stay with the desk, the chief actuary, and the product team. Every action carries decision provenance.
Layer 02 · Agents
Agent 01
Portfolio Watch
Continuous monitor on the bound book. Flags exposure drift, concentration breaches, and reserve development per segment.
Agent 02

fig. 05 · three layers, one closed loop
The data foundation
Most commercial submissions arrive with three to five years of loss runs attached. The bound-book slice is what every analytics tool ships. The full-submission-flow slice (the bound and the declined) is what turns the loop into appetite calibration. The market-wide slice is the augmentation layer that partially closes the counterfactual gap.
Tier 01 · Baseline
Renewal data, in-force exposure, concentration drift, reserve development. The classic portfolio analytics every PAS-based tool ships. Table stakes for what comes next.
Ships in the Sprint baseline.
Tier 02 · Appetite calibration
Loss runs from every submission, both bound and declined. Survivorship-bias correction. Appetite calibration from the risks the carrier passed on. Broker-quality scoring. Pricing benchmarks against a wider market sample. Specialty carriers see three to ten times more submissions than they bind. The appetite signal lives there.
Tuned in Enable. Aggregated, anonymized, and gated by a data-rights pass.
Tier 03 · Augmentation
Industry pools and external benchmarks layered over the carrier's own picture. Emerging-risk detection, cross-carrier trend analysis. Partially closes the counterfactual gap: what happened to the risks the carrier declined.
Expansion track. Realize-phase work, segment-specific.
North Star · The Reimagination
Underwriting today reads the portfolio on a calendar. Actuarial reviews, renewal cycles, post-mortems on loss runs that arrive after the deals were placed. The proposal is one connected loop. In the proposed model the bound book would update appetite the day the trend is detectable. Appetite would update the product the day the carrier decides. The line underwriter would see the change at the next quote.
Accountability stays where it is. The chief actuary sets the rules. The head of underwriting and the line underwriter own every appetite and binding call. Portfolio Lens makes the picture live. Decisions reach the desk before the next cycle.
Key use cases
UC-01
What this looks like for an MGA: the fronting capacity provider needs live appetite enforcement across broker channels. The blueprint would flag an industry concentration drift as the bound book moves. The chief underwriter would see dynamic line-size suggestions before the next tranche of submissions reaches the desk. A target we'd set jointly: zero accumulation surprises at the next quarterly cession review.
UC-02
What this looks like for a carrier: the commercial book shows loss-ratio drift in one sub-segment. The blueprint would surface it the day the trend is detectable, well before the next actuarial review. The head of underwriting would recalibrate appetite by channel and class. Line underwriters would see the change at the next quote. Combined ratio moves on selection.
UC-03
What this looks like for a reinsurer: aggregation drift across cedents and perils on treaty and facultative placement. The blueprint would flag exposure approaching treaty capacity ahead of renewal. The treaty buyer would adjust terms before the renewal cycle closes. The actuary would see the cession picture live, before the post-renewal report.
UC-04
What closing the loop looks like: the chief actuary surfaces a class drift in the bound book. The product team would adjust wording and limits. The line underwriter would see the updated product at the next day's quote. The wait for the next product release goes away.
UC-05
Most carriers pass on the majority of broker submissions. The loss runs that arrive with those declines are read once at decision time and then discarded. The blueprint would retain and analyze them in aggregate. The chief actuary would see where the carrier is mis-pricing, and which broker channels are surfacing the strongest risks. Appetite calibration would run against the full submission flow, declines included.
The bet
The full submission flow is the live input to every next decision. One loop, closed in minutes. The appetite layer, the integration contracts, and the playbook are yours at the end.
The asymmetry
The bound book is the highest-fidelity input to the next decision. Most carriers read it on a calendar cadence. The blueprint reads it live. The results reach the desk, the product team, and the treaty table.
The integration posture
Your PAS, your workbench, and your reinsurance ledger stay in place. The blueprint connects to them through APIs. No replatform required: what you run today keeps running.
The compounding return
Every bound risk and every loss tunes the appetite layer. The class that surprised the book last cycle flags automatically this cycle. Patterns the chief actuary approves become rules. Selection compounds before pricing has to.
The window
Reinsurance softening accelerated at 1/1/26. Lloyd's priced negative for the first time in seven years.Moody's · Lloyd's FY 2025 Carriers that build the closed loop now will start the next hard market from a stronger position.
The risk
What we don't know
How the back-test fits your book shows only once we run it on your data: your appetite curves, broker league tables, historical loss taxonomy, and the concentration shape of your treaties. The Sprint returns a confidence range. Enable turns it into evidence, or shows it doesn't hold.
What we will not do
The chief actuary, the head of underwriting, and the line underwriter keep their roles, and your PAS, workbench, and reinsurance ledger stay in place. Every appetite call and product change stays with your people, under your controls and on your audit trail. Regulatory accountability stays with your team.
What we phase carefully
The full-submission-flow analysis, meaning declined-risk loss runs in aggregate, is what sets Portfolio Lens apart. It is also where data rights and privacy obligations land hardest. Tier 2 ships in Enable, after the legal pass on aggregation and use is on file. Declined-submission analytics stay out of any external collateral until you clear them.
The engagement model
Three phases, starting with the back-test. Sprint runs on your own historical loss runs. The case for the blueprint, on your own book, before any commitment to Enable. Provectus operators then join your underwriting and actuarial teams. We run old and new in parallel for one renewal cycle. We scale only once the comparison favors the closed loop on every metric.
01
Weeks 1–2
Prove the case on your own loss runs.
02
One renewal cycle
Run old and new in parallel. Same book.
03
Cycle over cycle
Scale across lines. Own the loop.
Commitments
Bounded confidence
One line in Enable. One renewal cycle of parallel runs. Head-to-head on combined ratio, loss ratio, hit ratio, and concentration variance. We scale only when the comparison favors the closed loop.
Confidence range, not promise
Sprint returns a measured range on what Enable would deliver. Accuracy ceilings, time-to-signal deltas, exception coverage. The range is based on the data we see on your book. We commit to that range, and only to numbers the data supports.
Designed for the loop
The bound book and the full submission flow feed the appetite layer continuously. Declines are in once data rights clear. Updates arrive within minutes. We design for that contract on day one. Every trigger reproducible. Every replay auditable.
Named trade-off
The blueprint runs above the systems of record. We accept that constraint: it keeps the regulatory audit story clean and the adoption path short. It also means problems that belong inside the PAS or the workbench stay out of scope.
Next Step
If Portfolio Lens fits your book, the next step is a Baseline Assessment: one to two weeks, read-only against your historical loss runs, with no change to the underwriter's workflow. We measure what the closed loop would have surfaced against your actual decisions, then decide together whether to proceed. If the back-test doesn't support a strong business case, we tell you.
