DeclineTrail

1. One-liner

Captures the carrier declinations behind every surplus lines placement, so an audit two years later doesn’t void the policy.

2. Trend signal — why now?

The surplus lines market is booming and the compliance software built for it solves the wrong half of the problem.

The market first. Surplus lines premium hit $46.2 billion in H1 2025, up 13.2% year over year, with 3.7 million premium-bearing items filed with stamping offices through mid-2025, a 12.4% rise. Property risk keeps getting pushed out of the admitted market — wildfire, wind, habitational, contractors — and it lands in E&S. More placements means more diligent searches, and the volume is compounding at double digits.

Now the part nobody tooled for. Every surplus lines placement carries two obligations: file and pay the tax, and prove you tried the admitted market first. The entire compliance software category — InsCipher, Sircon/Vertafore, ReSource Pro — automates the first one. InsCipher’s own page on diligent search describes the regulatory history and then sells you tax compliance, filing, and reporting. Their product does not produce the declination record.

That’s backwards relative to the actual risk. From the industry’s own compliance analysis: late tax filings are the most common violation, but incomplete diligent searches carry the highest risk — a regulator who finds a deficient search can void the surplus lines placement entirely, impose fines, and trigger E&O exposure for the producing broker. A pattern of deficient searches escalates “from individual fines to license suspension proceedings.” Diligent search is called out as “the single most common compliance failure point in surplus lines placements.”

And the rules are a genuine 50-state maze that no spreadsheet survives:

• Most states require at least three declinations. Ohio requires five or more. Florida treats three as a floor, not a ceiling — except residential property over $700,000 replacement cost, where one declination suffices.
• Louisiana, Mississippi, Virginia and Wisconsin dropped the requirement entirely. Illinois exempts commercial risks referred by unaffiliated retail producers.
• New York bars counting declinations from affiliated insurers under common control unless they “operate as distinct and autonomous entities.”
• A new diligent effort must be undertaken on renewal. New York guidance says so explicitly; the California Surplus Lines Association mandates searches “on all new and renewal policies (even if the insured wants to remain with the surplus lines insurer).” Florida requires documentation “on a risk-by-risk basis.”
• Price alone is not a permissible declination reason in many states.
• Only a state can exempt a coverage via its export list — brokers cannot make that call themselves.

Enforcement is not hypothetical. In 2018 the New York Department of Financial Services issued a consent order against a broker who obtained declinations from three authorized insurers once annually and then reused them across placements. That is precisely the shortcut a busy agency takes when there’s no system.

Meanwhile the money already being spent proves the willingness to pay: an agency writing $5M–$25M in premium runs 0.25 FTE plus $8K–$12K in tech, for $35K–$50K a year on surplus lines compliance. An agency with 10 active producers across 8–12 states submits 400–1,200 individual filings annually. The staff exist. The budget exists. The declination half of their job is still done in email folders and PDF attachments.

Provenance:

• Signal 1 (demand): Diligent search identified as “the single most common compliance failure point in surplus lines placements”; deficient search lets regulators void the placement, fine the broker, and trigger E&O; agencies at $5M–$25M premium spend $35K–$50K/yr on surplus lines compliance — https://www.sonant.ai/blog/insurance-agency-surplus-lines-compliance — observed 2026-08-25
• Signal 2 (feasibility): Troutman Pepper Locke deep dive documents the state-by-state ruleset — 3 declinations standard, Ohio 5+, LA/MS/VA/WI eliminated, NY affiliate bar, renewal re-search mandate, Florida risk-by-risk, price-alone impermissible, state-only export lists — a deterministic rule engine over an unstructured evidence problem — https://www.troutman.com/insights/a-deep-dive-into-the-diligent-effort-search-requirement/ — observed 2026-08-25

• Signal 4 (competitive gap): InsCipher’s own diligent-search explainer sells tax compliance, filing and reporting — not declination documentation; the category automates the filing half only — https://www.inscipher.com/blog/diligent-search — observed 2026-08-25
• Signal 5 (enforcement precedent): 2018 NYDFS consent order against a broker who reused three annual declinations instead of searching per risk — https://www.troutman.com/insights/a-deep-dive-into-the-diligent-effort-search-requirement/ — observed 2026-08-25 Category: Underserved niche

3. The opportunity

The surplus lines compliance stack automated the structured, post-placement obligation and ignored the unstructured, pre-placement one.

Tax filing is a beautiful software problem: you have a bound policy, a premium number, a state, and a rate table. It’s deterministic, it happens after the fact, and the data is already in the AMS. That’s why InsCipher, Sircon and ReSource Pro all solved it.

Diligent search is an ugly software problem, which is exactly why it’s still open. The evidence lives as:

• Submission emails to five carriers, sitting in a producer’s Outlook
• Two declination replies as PDF attachments, one as a body-text “we’ll pass on this one”
• A carrier portal screenshot nobody saved
• An oral declination from an underwriter at lunch, which several states require you to reduce to writing
• Nothing at all for the other three carriers, because the producer bound it and moved on

Then, eighteen months later, a stamping office pulls the file. The questions are: did you get enough declinations for this state, from unaffiliated carriers, for this specific risk, dated before binding, on this renewal and not recycled from last year, for a reason other than price. The agency’s answer is a shrug and a search of somebody’s inbox.

The incumbents are structurally wrong for this three ways. Wrong data: they ingest policy records from the AMS; the declination evidence never enters the AMS. Wrong moment: they engage after binding, when the search is already deficient or complete and unfixable. Wrong price and onboarding: $8K–$30K a year with 3–10 week implementations aimed at agencies with a dedicated surplus lines administrator — the 5–20 producer shop has no such person and won’t sit through a ten-week rollout.

The 10× move is to sit on the evidence at the moment it’s created. Forward the carrier thread — or connect the mailbox — and the product reads unstructured submission and reply traffic, classifies each carrier response as a declination or not, extracts the date and the stated reason, checks the reason against the state’s impermissible-reason rules, counts unaffiliated declinations against that state’s threshold for that risk, and tells the producer before they bind: “Ohio needs five. You have three. Two of these are Liberty Mutual affiliates and count once. Go get two more.”

That is a pre-binding gate, not a post-hoc report. Nobody sells it.

4. Target market

• Primary customer: The compliance manager, operations lead, or agency principal at US retail and wholesale insurance agencies writing $3M–$40M in surplus lines premium, with 5–20 producers across 4–15 states. Concretely: a Dallas wholesale broker doing habitational and contractors E&S; a Florida retail agency pushed into surplus lines by the coastal property market; a Midwest agency writing trucking and cannabis. They already file taxes through InsCipher or a stamping-office portal.
• Why they buy: Because the failure mode is asymmetric and they know it. Fines run $500–$5,000 for individual diligent-search violations, and pattern violations escalate to license suspension — but the real terror is voiding the placement, which converts a compliance slip into an uninsured client and a direct E&O claim against the producing broker. The industry framing is blunt: incomplete diligent searches “carry the highest risk.” Every principal has heard the NYDFS recycled-declinations story or one like it.
• Rough TAM reasoning: Independent agents placed 62% of all US P&C premium in 2025. The surplus lines market ran $46.2B in H1 2025 premium across 3.7M stamping-office filings. The agencies in the $3M–$40M premium band writing E&S in multiple states number in the low thousands — call it 3,000–6,000 realistically addressable. At $500–$1,500/mo that’s a $50M–$100M addressable line. I need a few hundred of them, not all of them.
• Why now for them: Two things converged. Premium and filing volume are compounding at 12–13% a year, so the per-agency declination workload is growing faster than headcount. And admitted markets keep withdrawing from property lines, dragging agencies that historically wrote 5% surplus lines into writing 25% — they inherit a compliance obligation their processes were never built for.

5. Product sketch (MVP)

• Forward-or-connect capture. Forward a carrier submission thread to a per-agency address, or connect the producer’s mailbox. Every reply gets read and classified: declination, quote, request for more info, or silence.
• Declination extraction. Pulls carrier name, declination date, and the stated reason out of unstructured email bodies, PDF attachments, and portal screenshots — including the “we’ll pass, too much frame construction” that lives in a sentence, not a form.
• State rule engine. Encodes the per-state ruleset: declination counts (3 standard, Ohio 5+, Florida’s residential-property carve-out), the four states with no requirement, affiliate-grouping bars, export-list coverages, and impermissible-reason tests. Deterministic logic, versioned by state and effective date.
• Pre-bind gate. Before binding, a red/amber/green verdict per placement: how many valid unaffiliated declinations you hold, how many that state requires for this risk, and exactly which gap remains.
• Oral declination capture. A 30-second form (or voice note) that turns “Steve at Nationwide passed on the phone” into the contemporaneous written record several states demand, timestamped at creation rather than reconstructed later.
• Renewal re-search alarms. Flags every renewing surplus lines policy that needs a fresh search, because NY and California require one and recycling is the exact behavior that drew the 2018 consent order.
• Audit packet export. One placement, one PDF: the statement of diligent effort with every declination attached, dated, and reason-coded — in the destination state’s expected shape.
• Two-year+ retention archive. Immutable, searchable by insured, producer, carrier, state, and date.

6. AI angle — what’s load-bearing

Remove the AI and this product is a form that nobody fills in — which is precisely the status quo that’s failing.

The load-bearing work is reading unstructured carrier correspondence and deciding what it is. A declination is not a structured event. It arrives as “we’re not able to offer terms on this one,” “outside our appetite for habitational,” “declining — loss history,” or a PDF on carrier letterhead. Distinguishing a true declination from a request for more information, an indication, or a conditional quote is a judgment call over messy natural language, at a volume of hundreds of threads a month. That’s the job.

Second AI-load-bearing piece: mapping the stated reason to the state’s permissibility test. “Premium too high” is impermissible in many states. “Outside appetite for frame construction over three stories” is fine. The reason is written in underwriter shorthand and has to be judged against a legal standard.

The rule engine deliberately is not AI. Declination counts, affiliate grouping, and export lists are public, deterministic, and must be auditable — a regulator will not accept “the model thought three was enough.” The AI reads; the rules decide. That split is the whole architecture and it’s also the trust story.

7. Localization angle (if any)

N/A — this is a US-only play. The product’s entire value is encoding US state-level surplus lines regulation, which has no analog abroad. The “localization” here is interstate: each state is effectively its own jurisdiction with its own declination count, affidavit form, and exemption list. Launch in the highest-volume, strictest states — Florida, New York, Texas, California — and expand state by state. Adding Ohio’s five-declination rule is the same kind of work as adding a new country would be in a European product.

8. Business model — path to $1M–$5M ARR

• Pricing: Tiered by producer seat and state coverage. $399/mo (up to 5 producers, 3 states), $899/mo (up to 15 producers, 10 states), $1,899/mo (unlimited producers, all states, API into the AMS). Anchored well under the $8K–$12K/yr tech spend plus 0.25 FTE an agency in this band already absorbs.
• ACV: ~$9,600 realistic blended average (most customers land on the middle tier).
• Rough math to $1M ARR: 105 agencies × $899/mo × 12 = $1.13M. Roughly 2–3% of the addressable base.
• Rough math to $5M ARR: ~430 agencies at a blended $970/mo, or ~300 agencies plus wholesale-broker enterprise deals at $3–5K/mo. Requires all-50-state rule coverage and at least one AMS integration (Applied Epic or AMS360) to be table stakes.
• Expansion path: More producers, more states, then adjacent evidence obligations the same capture pipeline already sees — carrier appointment documentation, E&O file completeness, and the broader “prove you did the work” file. The mailbox connection is the wedge; everything downstream of it is upsell.

9. Go-to-market wedge — first 100 customers

• Stamping office filer lists are public. Florida (FSLSO), Texas (SLTX), California (SLA) and others publish or make obtainable lists of licensed surplus lines brokers and agencies. Pull the Florida and Texas lists, filter to agencies with 5–20 producers, and you have a named target list in the low thousands — not a persona, an actual list of companies with license numbers.
• The audit-bait cold email. Send a one-question email: “If Florida pulled three of your 2025 placements tomorrow, could you produce the dated declinations and the reason codes within 48 hours?” Attach a two-minute Loom showing a real forwarded carrier thread turning into a Statement of Diligent Effort. This question makes the recipient go check, and the checking is the conversion event. Expect 3–5% reply on a well-targeted 2,000-agency send.
• WSIA and state surplus lines association channels. The Wholesale & Specialty Insurance Association and state associations (FSLSO, SLA of California) run conferences, education tracks, and newsletters read exactly by this buyer. Sponsor one regional event, run a session on the 2018 NYDFS recycled-declinations consent order and what it means for renewal searches. This is a compliance audience that shows up for enforcement war stories.
• E&O carriers and agency networks as referrers. The E&O carriers underwriting these agencies have a direct financial interest in diligent-search discipline — a voided placement is their claim. Pitch two or three agency-focused E&O programs on a premium credit or a recommended-vendor slot. One network relationship delivers 20–50 agencies.
• Free state-by-state diligent search reference. Publish the definitive, maintained matrix — declination counts, affidavit requirements, export lists, renewal rules, by state, with effective dates. This is the thing every compliance manager currently reconstructs from a law firm PDF once a year. It ranks, it gets bookmarked, and it makes the rule engine’s credibility visible before anyone pays.

10. Build complexity — justification

Low. The capture layer is a mailbox connection plus document parsing on off-the-shelf models — the classification task (declination vs. quote vs. RFI) is well within current capability and needs no training data beyond a few hundred labeled threads. The rule engine is a versioned state table maintained by hand from public statutes and stamping-office guidance — tedious research, trivial code. No AMS integration is needed for v1; forwarding an email is the onboarding. A technical founder plus a part-time surplus lines compliance advisor ships a credible v1 for three or four launch states in 8–10 weeks. The hard part is domain research, not engineering.

11. Gating checklist

Gate	Pass?	Note
Legal in target market	✅	Recordkeeping software. Does not place insurance, give legal advice, or require any license. Positioned as evidence capture, not compliance certification.
Ethical — no harm / dark patterns	✅	Makes brokers do the search they’re legally required to do, rather than helping them fake it. Actively blocks declination recycling — the behavior NYDFS sanctioned.
Market exists (evidence above)	✅	$46.2B H1 2025 premium, 3.7M filings, agencies already spending $35K–$50K/yr on surplus lines compliance.
1–5 person team can build this	✅	Solo technical founder plus a compliance advisor. 8–10 weeks to v1.
Launchable with <$50K / ₹40L	✅	Inference, mailbox infra, and the domain advisor’s time. Well under $25K to first revenue.

12. Feasibility score

Axis	Weight	Score	Notes
Problem intensity	20	17/20	Deficient search voids the placement and triggers E&O — asymmetric, career-level downside. Felt on every single placement, not annually. Docked 3 because it’s a tail risk: most agencies go years without an audit, which dulls urgency.
Demand evidence	15	12/15	Hard spend ($35K–$50K/yr per agency), growing market (+13.2%), incumbents with real revenue, documented enforcement action. Docked 3 for thin direct customer voice — I found regulatory and vendor analysis, not brokers complaining in public forums. That’s a real gap in the evidence.
Build feasibility	15	13/15	Mailbox + classification + rule table. No novel infra. Docked 2 for the per-state research burden, which is genuine and ongoing.
Distribution clarity	15	12/15	Public stamping-office filer lists give a named target list; WSIA and E&O carriers are real channels. Docked 3 because insurance agencies are slow buyers and the trigger event (an audit) is unpredictable.
Revenue mechanics	15	12/15	Pricing sits comfortably under existing spend; ~105 agencies to $1M. Docked 3 because ACV depends on multi-state expansion that a small agency may not need.
Time to first revenue	10	8/10	8–10 week build, and this is a paid-pilot-friendly buyer. Realistically 3–4 months to first dollar.
Defensibility	10	3/10	Honestly weak. The rule table is public law and copyable; the classification is commodity AI. The only moat is the accumulated evidence archive creating switching cost, and InsCipher or Vertafore could bolt this on in two quarters if they noticed. Speed and focus are the entire defense.
Total	100	77/100

13. Qualitative modifiers

Founder-fit tags

technical-heavy · domain-expertise-required

You need someone who can build a document-classification pipeline and someone who genuinely knows surplus lines regulation. If the founder isn’t the second person, they must recruit a compliance advisor in week one — the state rule table is where this product lives or dies, and getting Ohio’s threshold wrong destroys trust permanently.

Key assumptions to validate (3–5)

1. Assumption: Agencies in the $3M–$40M premium band genuinely cannot produce a complete declination file on demand today. How to test: Ask 25 compliance managers the audit-bait question directly — “could you produce dated declinations plus reason codes for three 2025 placements within 48 hours?” Count how many say yes without hedging.
2. Assumption: Declination classification from real carrier email traffic is accurate enough to be trusted at a pre-bind gate. How to test: Get 300 real carrier threads from two friendly agencies under NDA, label them by hand, and measure precision on the declination class. Below 95% precision the pre-bind gate is worse than useless — it creates false confidence.
3. Assumption: Agencies will connect a producer mailbox to a third-party tool. How to test: Put the mailbox permission ask in the first 15 sales conversations and count objections. If it’s a blocker, forward-only becomes the primary flow and onboarding friction rises materially.
4. Assumption: Willingness to pay $899/mo for the diligent-search half when they already pay for the tax half. How to test: Price-test at $399 / $899 / $1,899 across the first 30 conversations; check whether budget authority sits with the same person who owns the InsCipher relationship.

Risk flags

1. Incumbent absorption: InsCipher, Sircon or ReSource Pro already own the customer relationship, the AMS integration, and the compliance budget. If any of them ships diligent-search capture, the wedge closes fast. This is the top risk and the reason defensibility scored 3.
2. Liability positioning: If the product is perceived as certifying compliance rather than capturing evidence, a failed audit becomes the vendor’s problem. Contract language and product copy must be disciplined from day one — “your evidence, organized” not “you’re compliant.”
3. Regulatory drift toward irrelevance: The long-run trend, per InsCipher’s own framing, has been to lessen the diligent search burden — four states have eliminated it outright. If that accelerates, the addressable problem shrinks underneath the product.
4. Thin direct customer voice: I could not find brokers complaining about this in public forums, only regulatory and vendor analysis. Either the pain is quiet and internal, or it’s less acute than the compliance literature implies. This is the single biggest reason confidence is Medium and not High.

14. Structured verdict

Score:                  77/100
Verdict:                GO
Confidence:             Medium
Best-fit builder:       Technical founder who can ship a document-classification
                        pipeline, paired with a surplus lines compliance advisor
                        (former stamping office or agency compliance manager)
Time to revenue:        3–4 months (8–10 week build + paid pilots)
Capital to launch:      $20–25K
Top 3 assumptions to validate first:
  1. 25 compliance managers answer the 48-hour audit question — count the honest "no"s
  2. Declination classification hits ≥95% precision on 300 hand-labeled real carrier threads
  3. Price test $399/$899/$1,899 across 30 conversations; confirm budget authority
Kill criteria:
  - Abandon if >60% of 25 compliance managers say they could produce a complete
    dated declination file within 48 hours today
  - Abandon if declination classification precision stays below 95% after two
    iterations on real carrier email traffic
  - Abandon if InsCipher, Vertafore/Sircon or ReSource Pro ships diligent-search
    evidence capture before v1 launch
  - Abandon if fewer than 3 of the first 30 targeted agencies will pay for a
    paid pilot at $399/mo or above

15. Next step — 1-week validation sprint

• Day 1–2: Build the target list. Pull the Florida (FSLSO) and Texas (SLTX) licensed surplus lines broker lists, filter to agencies with 5–20 producers, and assemble 200 named contacts. In parallel, hand-build the state rule table for exactly four states — Florida, New York, Texas, Ohio — from statute and stamping-office guidance. Ohio is in the set deliberately because its five-declination rule is the sharpest demo.
• Day 3–4: Send the audit-bait email to 200 agencies and book calls. On every call, ask the single falsifiable question first, before pitching anything: “Could you produce the dated declinations and reason codes for three 2025 placements within 48 hours?” Record yes/no/hedge verbatim. Separately, ask two friendly agencies for 300 real carrier threads under NDA.
• Day 5: Hand-label the 300 threads and run a classification pass to measure declination precision. Then decide.

Go / no-go: Proceed only if both are true — (a) at least 15 of 25 compliance managers cannot confidently answer the 48-hour question with an unhedged yes, and (b) declination classification precision on the 300 real threads is ≥95%. Fail either and this is a nice observation about regulation, not a business. The first test is falsifiable in a week and it’s the one that matters: if brokers can already produce the file, there is no product here.
