Coastal States Bank
Coastal States Bank runs two businesses on one balance sheet: the #1 deposit franchise in Beaufort County (plus Savannah and Atlanta) and a set of national specialty lending lines (Marine & RV, SBA / Government Guaranteed, Senior Housing, Mortgage Banker Finance). It just listed its holding company, CoastalSouth Bancshares, on the NYSE (COSO). Yet not one loan product has a self-serve digital front door. Account opening is online (openlocal.coastalstatesbank.com), but marine borrowers are told to call a support line, and mortgage, home equity, and commercial all end at 'contact a banker.' The Fiserv digital-banking stack for existing customers is already in place; what is missing is a single, branded, verify-as-you-go intake for the lending side.
The borrower journey today
How a prospective borrower actually moves through Coastal States’s digital properties right now, line by line.
What we’d change
A national specialty lender with no online apply
Marine, RV, SBA, and senior-housing lending are pitched to customers across the country, but a prospect who finds the site at 9pm has nowhere to apply. The marine page routes to a phone line and email built for servicing existing loans. For a national channel, that is the single biggest leak: out-of-market demand arrives digital-first and leaves the same way.
Account opening is online; lending is not
Coastal States already proved it can open a deposit account online (openlocal.coastalstatesbank.com). The harder-dollar products, where verification actually matters, have no equivalent. The capability gap is not technical willingness; it is that lending intake never got the same digital front door deposits did.
You already run the platform to fix this
Coastal States is on Fiserv for digital banking (the login portal resolves to Fiserv's shared platform). A white-label intake that verifies the borrower and syncs the application into the Fiserv core is an incremental addition to a stack the bank already runs, not a rip-and-replace. The gap is intake and verification, not infrastructure.
Specialty files are the slowest, and they are all manual
Marine, SBA, and senior-housing files carry the heaviest verification loads in banking: collateral and vessel ownership, business financials, guarantor and beneficial-owner identity. Today all of that is collected after a phone call, the slow way, through document requests and follow-ups. With a fresh NYSE listing, every recovered verification hour lands on the efficiency ratio public investors now watch.
What it could look like
Below is a live, interactive white-label demo in Coastal States’s own branding: one front door, every product, with identity, income, and property verified automatically. Try it, or open it full-screen.
Today vs. with RAVEN
| Today | With RAVEN white-label | |
|---|---|---|
| Products you can start online | None (0 of 6) | Every product, one front door |
| National specialty demand | 'Call our support team' | Captured, verified, and queued 24/7 |
| Borrower effort | Phone call + document chase | Name, email, and a secure connect |
| Identity / income / collateral | Collected manually after the fact | Verified automatically in ~90 seconds |
| Rate visibility | None until a banker follows up | Optional instant estimate from your rate card |
| Into the core system | Re-keyed by staff | Synced to Fiserv automatically |
What your loan officer receives
The instant a borrower finishes that flow, a fully verified application lands in the RAVEN dashboard and syncs to Fiserv. No rekeying, no document chase, full audit trail.

What automated verification is worth at Coastal States
Coastal States runs two businesses: the #1 deposit franchise in Beaufort County, and a national specialty lender in marine, senior housing, and SBA. The specialty side lives on verification: vessel ownership, business financials, guarantor identity. The local side sits in one of the fastest-growing retiree markets in America. Both sides have a verification number attached. All figures below are estimates built from public data (FDIC, HMDA, CRA filings). See the methodology.
Where the time goes today
Roughly 942 files a year need borrower verification at Coastal States: identity, income, employment, assets, and property, collected today through document requests and follow-up calls.[3]
That is 0 staff hours a year in the expected case, recovered as origination capacity rather than headcount reduction.[1]
Value by lending line
Different files carry different verification loads. Commercial files (beneficial ownership, guarantors, business financials) take the longest; consumer files the least. Expected-case annual labor value:[1][2]
The full math
| Line | Conservative | Expected | Optimistic |
|---|---|---|---|
| Staff time savings[1][2] | $169K | $303K | $479K |
| Pull-through revenue (0-2 added closings)[4] | $0K | $1K | $2K |
| Total estimated annual value | $169K | $304K | $481K |
The growth side: new residents, captured digitally
Roughly 2,500 new households move into Coastal States's footprint every year, and about 30% of movers open an account with a new bank. They shop with their phones. A white-label, fintech-grade intake flow (the same 5-minute experience above) turns that migration into a lead channel the bank owns instead of renting.[6]
| Annual | Conservative | Expected | Optimistic |
|---|---|---|---|
| Digital leads captured | 38 | 100 | 225 |
| Funded loans from those leads | 5 | 30 | 113 |
| Value (loan profit + avoided lead spend) | $6K | $54K | $258K |
This is new revenue, not savings, so it is shown separately and excluded from the headline number above.
Beyond the dollar math
Specialty files are the slowest files
Marine, senior housing, and SBA lending carry the heaviest verification loads in banking: collateral ownership, business financials, beneficial ownership, guarantors. These are the highest hours-per-file categories in this model.
The migration wave is unbanked on arrival
Roughly 2,500 households move into the Beaufort-Jasper footprint each year, and about 30% of movers pick a new bank. With 42 HMDA originations in 2024, nearly all of that lending relationship flow currently lands elsewhere.
Growth mode raises the cost of slow
A new Charleston team, a fresh NYSE listing, and an efficiency ratio eight points off its best mean every recovered verification hour lands directly on the metric public investors watch.

We also published an independent analysis of Coastal States's performance and market:
Read: The Boat Bank of Beaufort CountyMethodology & footnotes
Hours saved per file. Published verification-automation case studies (Blend Labs, 2025) report 15-16+ staff hours saved per mortgage file across loan officers, processors, underwriters, and compliance. We model mortgages at 6-14 hours, commercial files (which add beneficial ownership, guarantor identity, and business financials) at 8-16 hours, and simpler consumer or HELOC files at 2-6 hours. The expected case sits well below published benchmarks on purpose.
Loaded staff cost. The $38-48/hour range blends Bureau of Labor Statistics OEWS rates for South Carolina loan officers (~$30/hr), processors (~$28/hr), underwriters (~$55/hr), and compliance staff (~$50/hr), including benefits. Most verification labor falls on processors and loan officers, which is why the blend sits closer to the lower rates.
Verification volume. Mortgage counts come from HMDA Modified LAR filings via FFIEC, which report actual originations. Commercial, HELOC, and consumer volumes are estimates derived from FDIC call report loan mix and branch footprint; they are not reported figures and could vary materially. The 60-day pilot exists to replace these estimates with the bank’s own measured numbers.
Pull-through improvement. The MBA reports roughly 68% industry-wide mortgage application abandonment. We model a 1-5 percentage-point improvement applied to originations (not the larger application pool, which would produce a roughly 3x bigger figure), at the MBA-reported $785 average profit per closed loan. Published case studies report 10-15 point gains; our optimistic case is one-half to one-third of that.
What this is not. These figures are directional estimates built from public data and industry benchmarks. They are not a quote, a guarantee, or an analysis of the bank’s internal workflows, and recovered hours are modeled as redeployed origination capacity rather than headcount reduction. Banks already running highly automated verification will see less; banks running fully manual document collection will see more.
New-resident lead generation. TD Bank research reports roughly 30% of consumers open an account with a new bank after moving (and movers 55+ switch at a higher rate than millennials), while 91% of consumers say digital capability matters in choosing where to bank (MX, 2025) and more than half of online banking applications are abandoned mid-flow (The Financial Brand; Innovatrics). We model a bank with a white-label, fintech-grade intake flow capturing 1.5-9% of new-to-market households as started applications, converting 12-50% of those to funded loans (expected case: ~55% completion times the MBA-reported ~55% depository pull-through). Value per funded loan combines the $785 MBA average profit with $500-1,500 of avoided lead-acquisition spend, the going rate per funded loan from purchased shared and exclusive lead channels. New-household counts are derived from Census county population estimates and are not bank-reported figures. This line is shown separately and is not included in the headline savings number.
