South Atlantic Bank
South Atlantic Bank is a well-run $1.98B community bank serving the Carolina coast from Myrtle Beach to Hilton Head, and every loan product on its site except mortgage ends with a contact form or a phone call. Mortgage now links each loan officer's application on a third-party ICE portal (sab.mymortgage-online.com), off the bank's domain. Personal loans, auto, HELOC, and all business lending categories have no online apply button at all. The bank runs Jack Henry's Banno platform for digital banking (confirmed by the OAuth flow at my.southatlantic.bank) and has a branded goMobile app, so the digital infrastructure exists. What's missing is a borrower intake layer: a new customer who finds South Atlantic Bank at 9 PM, wants a HELOC on a coastal vacation home or a commercial expansion loan, has no path forward until business hours.
South Atlantic Bank's 12 offices span the South Carolina coast: Horry County (Myrtle Beach, North Myrtle Beach, Murrells Inlet), Georgetown County, the Charleston area (Charleston, Mount Pleasant, Summerville) and the Lowcountry (Bluffton, Hilton Head Island, Beaufort). Horry County grew 17.8% from 2020 to 2024 (Census Bureau), driven by in-migration. The bank serves a borrower base that skews toward retirees relocating from northern states, tourism-driven commercial borrowers, second-home buyers, and resort-area construction developers. The combination of high in-migration rates, active vacation home and CRE construction, and a relatively affluent transplant demographic creates strong ongoing demand for mortgage, HELOC, and commercial real estate financing.

What we’d upgrade
Only mortgage has a digital intake path, and it is off-brand
Personal, auto, HELOC, and the full commercial portfolio require a phone call or branch visit to begin. Mortgage is the exception: each loan officer's application now opens on a third-party ICE portal on a separate domain. The bank serves a coastal market where a large share of borrowers are purchasing vacation properties, relocating from out-of-state, or running seasonal businesses. All of these buyers apply outside normal hours and compare multiple lenders at once. Outside mortgage, South Atlantic Bank is invisible at the moment of highest intent.
The Jack Henry stack is already in place; the intake layer is missing
The bank runs Jack Henry's Banno digital banking platform (confirmed by the OAuth flow at api.banno.com behind my.southatlantic.bank) and ships a goMobile app with modern features. The core infrastructure is not the constraint. What's missing is a verify-as-you-go borrower intake that connects the marketing site to the back-office workflow without a manual handoff. A RAVEN-built front door syncs directly into the Jack Henry core the bank already operates.
Vacation and coastal purchase demand has nowhere to land after hours
South Atlantic Bank's footprint runs from Myrtle Beach to Hilton Head — markets where a meaningful share of mortgage and HELOC demand comes from out-of-state buyers shopping on weekends, comparing coastal property options late at night, or making decisions during vacation travel. A 'call 843.839.0100' prompt is not a conversion path for that borrower. Every weekend evening is a quiet revenue leak.
Commercial intake relies entirely on relationship manager availability
The business lending page lists SBA loans, CRE, construction financing, working capital, and equipment loans — a competitive product set for a coastal SMB market. The only intake path is calling the main line. A verified digital intake for business borrowers — entity data, owner identity, and preliminary financials collected at first touch — would hand the relationship manager a workable file instead of a blank lead and shorten the pipeline by several days per deal.

Where the time goes today
Roughly 1,352 files a year need borrower verification at South Atlantic: 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]

Why this matters for South Atlantic
A $1.5B Loan Book Growing 8-10% a Year Needs Verification That Keeps Pace
South Atlantic Bank grew gross loans 10.0% in 2025 and 7.6% in the year to June 2026, to $1.54B, with real estate loans now about $1.4B across residential, construction, and commercial categories. That growth is being processed by 175 FTEs across 12 offices, a ratio that leaves little slack for manual document chasing. HMDA mortgage originations rose from 225 to 252 in 2025 ($113.5M to $148.4M), meaning the bank is writing more loans without visible investment in automated verification to handle the throughput. RAVEN replaces the income-stub shuffle and borrower follow-up that eat underwriter hours at precisely the loan volume where friction compounds: when every basis point of efficiency ratio matters and you are trying to close more files without adding headcount. At South Atlantic's current growth trajectory, the cost of not automating borrower verification is measured in delayed closings, missed rate locks, and loan officers spending afternoons on file cleanup instead of production.
Horry County's In-Migration Wave Is a New-Borrower Acquisition Machine
Horry County grew 17.8% from 2020 to 2024, driven by in-migration: retirees, remote workers, and second-home buyers choosing the Grand Strand over Florida. These borrowers do not have existing banking relationships in South Carolina and are actively shopping for mortgages, HELOCs, and auto loans. South Atlantic Bank is competing for these borrowers against national lenders who offer fully digital applications with instant income verification. RAVEN lets a community bank match the digital experience of Rocket Mortgage or Better.com at application intake, verifying identity, income, employment, and assets in minutes rather than days, which is exactly the differentiation a $1.9B bank needs to win a transaction borrower who has no loyalty anchor. The bank's 3.8% annual county growth rate means roughly 7,500 net new households per year enter the footprint as potential first-time customers, and the bank that closes fastest captures the relationship.
Construction and CRE Concentration Demands Faster Commercial Borrower Underwriting
South Atlantic Bank carries $266M in construction and land development loans (up 40% in a year) and $592M in nonfarm nonresidential CRE, together about 56% of its loan book. These borrowers are developers, resort operators, and commercial real estate investors who expect transactional speed and view document-collection delays as a relationship risk. Commercial loan officers who manually request two years of business tax returns, bank statements, and entity documents from a developer building a condominium project on the Grand Strand are leaving the door open for a more responsive competitor. RAVEN's commercial income and asset verification closes that gap by letting the bank issue a faster term sheet backed by verified financials, not a pending checklist. For a bank growing C&I and CRE in a hot coastal construction market, verification speed is a competitive differentiator that shows up directly in relationship retention and pipeline close rates.

Bank Tech Stack TrackerMethodology & 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 included in the headline total.
