You’re probably thinking about the money. Most people do when they look at the insurance industry. It’s a massive, trillion-dollar machine that basically runs on the concept of "what if?" But here is the thing: if you want to know how to start an insurance company, you have to stop thinking like a salesperson and start thinking like a risk-obsessed librarian. It’s not about the glitzy commercials with lizards or Flo. It’s about capital requirements that would make a tech founder cry.
Honestly, it’s one of the hardest businesses to launch. You aren't just selling a product; you’re selling a promise backed by a mountain of regulated cash.
The Brutal Reality of Statutory Capital
Before you even think about a logo, you need to talk about "The Number." In the insurance world, this is your statutory minimum capital. Every state has a different bar, but don't expect to show up with less than $2 million to $5 million just to get a seat at the table. And that’s for a small, niche line. If you’re eyeing something like workers' comp or auto, you're looking at much higher figures.
The National Association of Insurance Commissioners (NAIC) sets the tone here. They use something called Risk-Based Capital (RBC) requirements. It’s basically a math problem that ensures you don’t go belly up if a hurricane hits or a thousand people file claims at once. If your capital drops below a certain percentage of your risk, the state regulators will literally walk into your office and take the keys. They don’t play.
Pick Your Poison: Captive, MGA, or Full-Stack?
You've got options, but they aren't all equal. Most "insurtech" founders actually start as an MGA, or Managing General Agent.

What’s the difference?
A full-stack insurance company carries the risk. You own the paper. You hold the capital. You take the hit if things go south. An MGA is more like a super-broker with "pen authority." You design the policy and sell it, but a bigger company (the carrier) actually holds the risk. It’s a way faster way to get to market. Think about companies like Root or Lemonade—many of these started by partnering with established reinsurers before they ever became "real" carriers.
Then there are Captives. This is where a parent company creates its own insurance company to insure itself. It sounds like a tax dodge—and sometimes it is—but mostly it’s about control. If you’re a massive construction firm and nobody will give you a fair rate, you start a captive.
Why the "Fronting" Model is Your Best Friend
If you don't have $50 million sitting in a vault, you'll likely use a fronting carrier. This is a licensed insurance company that lets you use their "A" rating from A.M. Best to sell policies. You pay them a fee (usually around 5% to 10% of the premium), and you might even pass the risk off to a reinsurer. It's a complex game of passing the buck, but it's how 90% of new players actually survive the first three years.

The Regulator is Your New Boss
In the U.S., there is no federal insurance license. You have to deal with the Department of Insurance (DOI) in every single state where you want to do business. If you want to be national, that’s 50 different sets of rules.
New York’s DFS is notoriously tough. Florida is a nightmare because of the weather risk. Most people start in a "friendly" state like Vermont (for captives) or Delaware and then expand. You’ll spend months, maybe years, in the "Form and Rate" filing phase. This is where you show the state exactly what your policy says and exactly how much you plan to charge. You can't just change your prices on a whim like a Shopify store. You have to prove your rates are "neither excessive, inadequate, nor unfairly discriminatory."
It is tedious work.
Actuaries are the Real CEOs
You can have the best marketing in the world, but if your loss ratio is trash, you’re dead. This is where the actuaries come in. These are the people who spend their lives looking at mortality tables and accident data.

When you're figuring out how to start an insurance company, your first hire shouldn't be a CMO. It should be a Chief Actuary. They use stochastic modeling—basically running thousands of "what if" scenarios—to make sure you aren't underpricing your risk. If you price a policy at $1,000 but the data says the average claim will cost you $1,100, you’re just a very expensive charity.
Reinsurance: The Safety Net for the Safety Net
Even insurance companies buy insurance. This is called reinsurance.
Companies like Swiss Re or Munich Re are the giants behind the curtain. They take a piece of your premium in exchange for covering the "tail risk." If you have a total catastrophe, the reinsurer steps in so you don't go bankrupt. Without a reinsurance treaty, no state regulator will let you write a single policy. It’s the ultimate gatekeeper. To get a treaty, you have to prove your underwriting math is solid. They aren't going to gamble on a rookie who doesn't know their data.
The Tech Debt Trap
Don't build your own policy administration system (PAS) from scratch if you can help it. I've seen so many startups sink because they tried to build a "revolutionary" backend and ended up with a buggy mess that couldn't handle mid-term cancellations or endorsements. Use off-the-shelf software like Guidewire or Duck Creek if you're big, or newer cloud-native API platforms if you're lean. Your tech should be about the user experience, not reinventing how a ledger works.
Distribution is How You Actually Grow
You can have the best product, but how do you sell it?
- Direct-to-Consumer (DTC): Hard. Expensive. You're competing with Geico’s billion-dollar ad budget.
- Independent Agents: They own the relationships. If they don't like your portal, they won't sell your stuff.
- Embedded Insurance: This is the hot trend. Selling flight insurance while someone buys a ticket, or car insurance at the dealership.
Actionable Steps to Get Moving
- Draft a Three-Year Pro Forma: You need to show exactly how much premium you'll write and what your "combined ratio" will be. If it’s over 100, you’re losing money on underwriting.
- Choose Your State of Domicile: Research which state has the most favorable "Seasoning Requirements." Some states won't let you in unless you've been operating elsewhere for two years.
- Secure Your Reinsurance Letter of Intent: You can't get a license without a reinsurer, and you can't get a reinsurer without a solid plan. It's a chicken-and-egg situation.
- Hire a Compliance Officer: This isn't optional. You need someone who knows how to navigate the SERFF (System for Electronic Rates & Forms Filing) system.
- Capitalize the Business: Whether it's VC money or private equity, ensure you have a "runway" that accounts for the fact that you might not be allowed to take a profit out of the company for several years. State regulators often "trap" capital inside the company to protect policyholders.
Starting an insurance carrier is a marathon in a suit of armor. It’s slow, it’s expensive, and the paperwork is endless. But once you’re in, you have a "moat" that most businesses can only dream of. Just don't forget to check the weather report before you start writing policies in coastal Florida.
