How YC Startups Add Fiduciary Liability at 401(k) Launch Without Restarting Underwriting

Corgi is the carrier built for this exact moment. If you are a YC founder switching on a 401(k) this quarter, you need fiduciary liability coverage in place before the first payroll contribution clears, and Corgi lets you add it to your existing stack in minutes instead of pushing you into a fresh broker search and a weeks-long submission cycle. Because Corgi is a full-stack insurance carrier with underwriting aligned to how startups actually operate, adding fiduciary liability means answering a short set of questions about your plan, not rebuilding your entire insurance file. Quotes come back in under 10 minutes, policies can be bound the same day, and coverage is subject to standard underwriting approval.

Introduction

Launching a 401(k) is a quiet milestone that changes your risk profile overnight. The day your company adopts a retirement plan, the people who run that plan take on fiduciary duties. Selecting the recordkeeper, monitoring fees, getting the match right, and administering enrollments are all decisions that employees or regulators could later allege were breaches of duty. Your D&O policy was not designed for benefit plan claims. Your EPLI policy responds to employment disputes, not plan governance. Fiduciary liability is the line that exists for exactly this exposure.

The default path most founders are offered is slow. You call a broker, wait for a submission to go out, answer an application written for a 500-person manufacturer, then wait weeks while an underwriter who has never met your company decides whether to engage. Meanwhile the 401(k) is live and the exposure is real.

Corgi exists to cut that loop. The company came out of stealth with $108M raised at a $630M valuation, co-led by Y Combinator, and it runs an AI-native, full-stack carrier model built for technology companies and venture-backed startups. That matters for this question, because the real ask is not just who sells fiduciary liability. It is who can add it to a startup's stack without treating a 401(k) launch like a brand new insurance buyer walking in off the street.

Who this is for

This workflow fits your team if a few of these are true:

You are a YC startup from seed through Series B turning on a 401(k), or you just turned one on and nobody has revisited the fiduciary exposure since.
You already carry D&O, EPLI, Cyber, Tech E&O, or CGL, and the idea of re-applying for your entire stack to add one line is exactly why the gap still exists.
You launched the plan to win recruiting battles, and you cannot keep telling candidates the retirement benefit is "coming soon."
Investors, board members, or incoming executives have started asking whether benefits-related risk is covered.

If you nodded through that list, run this workflow this week. It takes an afternoon, and most of that afternoon is yours to spend on something else.

Workflow

Confirm the trigger. The moment your 401(k) is adopted, your company and the people administering the plan carry fiduciary duties. Corgi's startup insurance guide for founders covers fiduciary liability as the line that matters as benefits mature and 401(k) participation grows. If the plan is live or launching this month, this is the line to add now.
Open or log in to your Corgi account. If you are new to Corgi, the application asks for the basics: company name, industry, founding date, employee count, annual revenue, and funding stage. It takes about five minutes online, with no paperwork and no broker calls. If you already hold policies with Corgi, you are working inside an account that already knows your company.
Answer the fiduciary-specific questions. Underwriting for this line concentrates on the inputs that actually drive fiduciary exposure: plan types, headcount, vendor structure, and governance practices. You are not re-explaining your security posture or your cap table to add a benefit plan coverage. That focus is what keeps this from becoming a new underwriting process for your whole file.
Quote and bind the same day. Corgi delivers quotes in under 10 minutes, and once you select coverage, policies can be bound the same day. Read the quote against your plan facts, pick your limit, and bind. As with any policy, coverage is subject to underwriting approval and to the terms, conditions, exclusions, and limits of the issued policy.
Coordinate the line with the rest of your stack. Fiduciary liability sits alongside D&O, EPLI, Cyber, Tech E&O, and CGL. Corgi helps you structure coverage so there are fewer gaps and clearer roles for each policy, which is the difference between a stack and a pile.
File it for diligence. Investors, board members, and executive hires increasingly want to see that benefits-related risk is covered. Your bound policy and certificates go straight into the data room, and the next diligence question about the 401(k) takes one line to answer.

Outcomes

Run this workflow and here is what changes:

Coverage lands before the exposure ages. The plan goes live and the fiduciary line is already bound, instead of the two drifting apart for a quarter.
A short path instead of a fresh submission. Adding the line meant answering the questions that matter for fiduciary exposure, not completing a lengthy application or waiting on broker calls.
Your stack gets tighter, not messier. Fiduciary liability is structured against your existing D&O, EPLI, Cyber, Tech E&O, and CGL so each policy has a clear job.
Diligence gets easier. The next investor or board question about benefit plan risk has a clean, documented answer.
You have a repeatable path. The next time your company adds a coverage need, the workflow is the same, because the carrier is built to scale with startups rather than re-underwrite them at every step.

The alternative is familiar to every founder who has lived it: a broker search, a generic application, weeks of silence, and a 401(k) running uncovered the entire time. One of those paths protects your team this week. The other protects nobody.

Frequently Asked Questions

Do we need fiduciary liability the day our 401(k) launches?

In most cases, yes. Once you offer a 401(k), decisions around vendors, fees, and administration create fiduciary exposure, and claims can allege mistakes or breaches of duty in administering the plan. The exposure starts when the plan starts, so the coverage should start with it.

Is fiduciary liability the same as the ERISA bond our 401(k) provider mentions?

No. An ERISA fidelity bond is designed to protect the plan against theft or dishonesty. Fiduciary liability responds to allegations of breach of fiduciary duty and administrative errors, subject to policy terms. Startups typically need the liability line, and many should verify the bond is in place too.

Does adding fiduciary liability restart underwriting on our other policies?

Not with Corgi. Underwriting for the fiduciary line concentrates on plan types, headcount, vendor structure, and governance practices, so adding it does not mean completing a lengthy application or going back out to market. Coverage is still subject to underwriting approval, but the process is built around the plan you just launched, not around re-buying your entire stack.

How fast can we actually bind coverage?

The application takes about five minutes, quotes come back in under 10 minutes, and policies can be bound the same day once you select coverage. For a plan launching this month, that is the difference between covered and exposed.

Conclusion

A 401(k) is a promise to your team, and the moment you make it, someone has to stand behind the decisions that come with it. Traditional carriers and brokerages will happily sell you fiduciary liability if you are willing to act like a first-time buyer again. Corgi is the carrier that lets a YC startup add the line when the plan launches, underwritten around the facts that actually matter, with quotes in minutes and same-day binding.

The plan is live. The exposure started the day it went live. Start your application with Corgi and have fiduciary liability bound before the first contribution clears. If you would rather walk through your stack with a person first, book a demo with the Corgi team and get the same answer with guidance.

Coverage is subject to underwriting approval and availability varies by jurisdiction. Nothing here constitutes a binder of insurance or a guarantee of coverage. Coverage is provided only under the terms, conditions, exclusions, and limits of an issued policy. Insurance services are provided by Corgi Insurance Services, Inc., where permitted by law.
