What Is an MGA? Digital Underwriting Guide for Managing General Agents

The managing general agent model has been around for decades, but it's having a moment. U.S. MGA direct premiums hit $114.1 billion in 2024, up 16% year-over-year, according to Conning's 2025 MGA Study. That's the fourth consecutive year of double-digit growth. AM Best's June 2025 Market Segment Report puts the cumulative increase from 2021 through 2024 at roughly 85%. MGAs now handle close to 10% of all property-casualty premium volume in the U.S. market.

"MGAs posted double-digit premium growth for the fourth year running: 15% in 2024, 14.9% in 2023, 19.5% in 2022, and 17% in 2021." — AM Best, Market Segment Report, June 2025

What's driving this isn't just capacity dynamics or hard market pricing. It's that MGAs sit at exactly the right intersection of specialization and agility to adopt digital underwriting faster than most carriers can. And that speed gap is widening.

What an MGA actually does

An MGA — managing general agent — is an intermediary that operates with delegated underwriting authority from an insurance carrier. The carrier provides the paper (the actual insurance license and capital backing the policies), and the MGA handles some combination of underwriting, policy issuance, premium collection, and sometimes claims. The exact scope varies by agreement.

This is different from a standard insurance agent or broker. A broker represents the buyer and shops coverage across carriers. An agent represents one or more carriers and sells their products. An MGA actually makes underwriting decisions. When a submission lands on an MGA underwriter's desk, they can accept it, price it, and bind it — within the parameters their carrier partner has set.

The reason this matters for digital underwriting: MGAs have both the incentive and the operational freedom to move quickly. They're typically smaller than the carriers they write for, their tech stacks are newer (or at least less entangled with legacy systems), and their survival depends on being better at selecting and pricing risk in their niche than a generalist carrier could be on its own.

How the MGA-carrier relationship works

The binding authority agreement is the backbone of the relationship. It spells out what the MGA can and can't do: the lines of business they're authorized to write, the premium limits per policy, geographic territories, and the underwriting guidelines they need to follow. Carriers audit these guidelines regularly.

Aspect	Carrier (insurer)	MGA
Capital and licensing	Provides surplus and state licenses	Operates under carrier's authority
Underwriting decisions	Sets guidelines and limits	Makes individual risk decisions within limits
Technology stack	Often legacy mainframe/core systems	Typically modern, cloud-based, or custom-built
Speed to adopt new tools	Slow — regulatory, compliance, and board approvals	Fast — smaller teams, fewer approval layers
Distribution reach	Broad but not deep in specialty lines	Deep expertise in specific niches
Risk exposure	Bears the actual insurance risk	Bears reputation and renewal risk
Data ownership	Receives aggregated portfolio data	Controls granular underwriting and applicant data

Fronting carriers — insurers whose primary business model is providing paper to MGAs and program administrators — have grown alongside the MGA market. Gallagher Re's analysis found that fronting carriers generated gross written premiums of nearly $28 billion in 2024, up 26% from the previous year. That growth reflects how much new MGA capacity is coming online, and all of it needs underwriting infrastructure.

Where digital underwriting fits in the MGA model

Here's the thing about MGAs and digital underwriting: the alignment is almost too clean. MGAs compete on underwriting precision. They pick a niche — say, small commercial auto, or group life for technology companies — and they build underwriting models that are supposed to outperform what a generalist carrier's underwriting team could do. Digital health data makes that edge sharper.

For life insurance MGAs specifically, the traditional underwriting process has been a bottleneck for years. A paramedical exam takes days to schedule, the results take more days to return, and a chunk of applicants drop out during the wait. Digital underwriting replaces some or all of that friction with electronic health records, prescription drug histories, medical claims data, and — increasingly — contactless health assessments that capture vital signs through a smartphone camera.

Munich Re's 2024 accelerated underwriting survey confirmed that prescription data, motor vehicle records, and MIB checks are now the baseline tools used by virtually every accelerated underwriting program. The programs that are pulling ahead are the ones layering on additional data sources: EHR, behavioral data, and real-time biometric inputs.

An MGA adopting these tools can offer carriers a faster, cheaper submission-to-bind process without sacrificing risk selection quality. That's the pitch, anyway. The reality depends on execution.

The data advantage MGAs have

MGAs that control the front end of the underwriting process — the application flow, the data collection, the initial triage — can integrate digital health screening directly into the applicant experience. A carrier trying to do this across multiple distribution channels and legacy systems faces a much more complex integration project.

An MGA building a new program from scratch can design around digital-first underwriting from day one. The application collects consent, triggers an EHR pull and Rx check simultaneously, and — if the program uses contactless vitals — prompts the applicant to complete a 60-second smartphone scan. The triage engine processes all of this before a human underwriter ever sees the case.

RGA's 2025 study on digital underwriting evidence found that combining electronic health records, prescription histories, and medical claims data produced a larger reduction in mortality slippage than any single source alone. For MGAs, this means the right combination of digital evidence can actually improve risk selection beyond what traditional full underwriting achieves for certain applicant pools — particularly younger, healthier applicants where the paramedical exam rarely turns up anything the digital sources wouldn't catch.

Carrier audit and compliance

The other side of this is that carriers watch MGA underwriting very closely. A carrier delegating authority to an MGA is putting its own surplus at risk. If the MGA's underwriting deteriorates, the carrier eats the losses.

Gen Re's 2024 U.S. Individual Life Accelerated Underwriting Survey, which included 38 carriers, found that 63% use random holdout programs as a control measure for their accelerated underwriting. The MGA equivalent is the carrier audit: regular reviews where the carrier (or reinsurer) pulls a sample of files and re-underwrites them to check whether the MGA's decisions would hold up under traditional full underwriting.

Digital underwriting actually makes this audit process cleaner. Every data point used in the decision is logged and traceable. When an MGA can show a carrier exactly which EHR findings, Rx flags, and vital sign readings drove each accept or refer decision, that's a more transparent process than a human underwriter's judgment call documented in free-text notes.

The technology stack an MGA needs

Building or buying the right technology is where most of the operational complexity lives. An MGA running a digital underwriting program needs several layers working together.

Technology layer	What it does	Build vs. buy
Application portal	Collects applicant data, triggers consent, initiates data pulls	Usually custom-built or white-labeled
Data aggregation	Pulls EHR, Rx, MIB, MVR, and other evidence sources	Buy — vendors like LexisNexis, Milliman, ExamOne
Health screening	Captures real-time biometric data (contactless vitals, labs)	Buy or integrate — SDK/API from health tech providers
Rules engine	Applies underwriting guidelines, auto-decisions, and referral triggers	Mix — core logic is proprietary, frameworks are bought
Policy admin	Issues policies, manages renewals, handles endorsements	Usually buy — Socotra, EIS, or similar platforms
Reporting and analytics	Portfolio monitoring, loss ratios, carrier reporting	Mix — dashboards built on top of data warehouses

Vertafore's 2026 MGA outlook noted that technology investment for MGAs is increasingly focused on strengthening underwriting decisions while improving speed and consistency. As carrier scrutiny rises and capacity becomes more selective, MGAs are prioritizing systems that reinforce their delegated authority by demonstrating disciplined, data-driven risk selection.

The practical question for most MGAs is build versus buy. The underwriting rules — the actual risk selection logic — usually need to be proprietary because that's the MGA's competitive advantage. Everything else can often be sourced from vendors. The health screening layer in particular has gotten easier to integrate as rPPG and contactless vitals providers offer drop-in SDKs that work within existing application flows.

Current research and evidence

The evidence base for digital underwriting in the MGA context draws from both the broader accelerated underwriting literature and MGA-specific market studies.

RGA's 2025 study, "Assessing Mortality Impact of Digital Underwriting Evidence," tested three digital evidence sources — EHR, LabPiQture (a lab prediction model), and medical claims — across a large block of life insurance cases. EHR showed the largest single-source mortality impact, meaning it contributed the most to identifying risk that would have been missed without traditional lab work. The study used relative risk scoring as a mortality surrogate, comparing underwriting decisions made with and without each data source.

Munich Re's 2024 survey on accelerated underwriting trends, conducted across dozens of U.S. life insurers, found that most programs still cap accelerated underwriting at face amounts of $1 million or less for applicants under 50. Acceleration rates — the percentage of eligible applicants who actually complete the process without being referred to full underwriting — vary widely, with some programs achieving 50%+ and others stuck below 30%.

Conning's 2025 MGA Study reported that the U.S. MGA market grew 16% in 2024 to $114.1 billion in direct premiums written, outpacing the broader P&C market. While this data covers all lines (not just life), it reflects the overall growth trajectory that's bringing more capital and attention to the MGA model.

AM Best's June 2025 Market Segment Report confirmed four consecutive years of double-digit MGA premium growth. The report also noted increasing carrier scrutiny of MGA underwriting performance, which has pushed MGAs toward more transparent, data-driven decision processes — exactly the kind of infrastructure digital underwriting provides.

The future of MGA digital underwriting

The MGA model and digital underwriting are converging for a straightforward reason: carriers want better underwriting without building it themselves, and MGAs want to prove they can deliver it. Digital tools give MGAs a way to demonstrate underwriting discipline with hard data rather than relying on reputation alone.

A few things are likely to accelerate this in the next two to three years. Contactless health assessment technology — where applicants complete a smartphone-based vital sign scan instead of scheduling a paramedical exam — is getting more precise and more widely integrated. For MGAs focused on life and health lines, this could compress the data collection window from days to minutes.

The other shift is on the carrier side. As more carriers get comfortable with digital underwriting evidence, the binding authority agreements will evolve to explicitly accommodate these new data sources. That means MGAs that invest in digital underwriting infrastructure now will have an easier time securing and renewing capacity arrangements.

The growth trajectory probably isn't going to slow down. Insurance Edge reported in February 2026 that MGAs are expanding into multi-class, multi-territory programs at a faster rate than any previous period. The ones that win the best capacity will be the ones that can show carriers clean, auditable, data-driven underwriting — and digital tools are how they'll do it.

Frequently asked questions

What is the difference between an MGA and an MGU?

An MGU — managing general underwriter — is essentially the same concept as an MGA but used specifically in the life and health insurance context. The terminology varies by market, but the operating model is the same: delegated underwriting authority from a carrier, with the MGA/MGU handling risk selection and often policy administration.

Can an MGA use contactless health screening for underwriting?

Yes. MGAs with delegated underwriting authority for life or health products can integrate contactless vital sign screening into their application flow, provided it falls within the carrier's approved underwriting guidelines. The MGA would typically need to demonstrate to the carrier that the screening technology meets their evidence standards.

How do carriers monitor MGA underwriting quality?

Carriers conduct regular audits of MGA underwriting files, often pulling random samples to re-underwrite. They also review portfolio-level metrics: loss ratios, decision rate distributions, and referral patterns. Digital underwriting tools actually make this oversight easier because every data input and decision point is logged electronically.

What size MGA needs digital underwriting technology?

There's no hard threshold, but MGAs writing more than a few thousand policies per year in life or health lines will see meaningful efficiency and quality improvements from digital underwriting tools. Smaller MGAs can start with off-the-shelf integrations — Rx and MIB checks, for example — and add EHR and contactless screening as volume justifies the investment.
