How to select a business structure without regret.

When is the best time to register your idea as a company?

From day one, the best companies optimize for three things: shipping speed, creative iteration, and decision velocity. I've said before that speed is a startup's biggest strength — but the biggest constraint for early-stage startups is also speed.

From a seed investor's perspective, the fastest teams are designed for leverage, not headcount. Lean startups are on the rise, but lean didn't start with AI. AI now just pushed it to the extreme: teams are smaller, roles are broader, and people move across functions without asking permission. Thus, expanding the scope of liability for all stakeholders — making structure relevant from day one.

“The best time to register your startup is right before you spend money, sign contracts, or raise capital. But how you incorporate can have a huge implications for your startup.”

Why This Matters: Startups are very different from normal businesses. Unlike a traditional business, to ensure that your startup is set up for success, you need a great idea, a product, a team, and you need to execute. Execution can happen across the four vectors of idea, product, team, and execution. But as you execute (build the waitlist, develop the product, identify partners, etc.,) there are several proactive steps that you can take in advance of receiving your first term sheet.

Let’s talk business structures.

Why you need a C-Corp

There are a few different entity types that you can set up when you incorporate. Each type has its pros and cons, depending on what kind of company you’re building. The two options startup founders tend to consider most often arelimited liability companies (LLC), andC corps. But even with just those two options, it can be daunting to understand which route to go.

Choosing an LLC doesn’t put you on a different path. It creates a structural debt you will pay later — with interest, or under deal pressure, and at the exact moment you can least afford the distraction.

For startups, entity-selection depends on exactly one question: do you ever intend to raise institutional capital?

If your answer is yes — read on. If genuinely never, there’s a section for you too.

Why VCs don’t invest in LLCs

This isn’t preference or habit. It’s mechanics.

Preferred stock doesn’t exist in an LLC.Stocks are paper representations of a company’s value. They are equitable instruments that can serves as a financial security and represents partial ownership in a corporation. The entire venture model runs on preferred stock — a class of shares carrying liquidation preferences, anti-dilution protections, and board rights. That’s what a VC buys.

LLCs don’t have stock, they have membership interests. If an LLC fails or gets sold, a holder of preferred stock gets their money back first, before common stockholders see a dime. Every standard term sheet, from YC’s SAFE to the NVCA Series A documents, assumes a corporation. Papering venture terms onto an LLC operating agreement is possible in theory but expensive, slow, and deal-repellent in practice.

LLC income poisons VC investors’ own funds.VC funds raise from limited partners — university endowments, pension funds, foundations. These LPs are tax-exempt, and pass-through income from an LLC can generate Unrelated Business Taxable Income (UBTI): taxable income flowing to entities whose entire structure depends on not having taxable income. A fund that invests in your LLC creates a tax problem for its own investors. So it won’t. Your startup that is structured as an LLC is filtered out before evaluation.

Employee equity breaks.When a startup wants to hire a great engineer, they usually can't pay top salary yet, so they sweeten the deal with equity — a promise of ownership in the company, with the hopeful expectation that the startup will become valuable later. A C-Corps handles this natively. The company sets aside a chunk of ownership called an option pool, and gives new hires stock options — the right to buy shares later at a fixed (usually cheap) price.

Stocks: What They Are, Main Types, and How They Differ From Bonds

A stock, also known as a share, is a tradable claim to fractional ownership of the corporation that issued it.

If you want to raise venture capital, you basically need to be a corporation with preferred stock — trying to do it through an LLC is swimming upstream against the entire industry's plumbing.

“I’ll just convert later”

You’re not being realistic. Here’s what “later” actually costs.

Converting an LLC to a C-Corp is a taxable event in many configurations — meaning the IRS may treat the conversion as a sale, and founders can owe real tax on paper gains before they’ve seen a dollar of liquidity. Beyond tax, showing up to a venture negotiation in an LLC tells the investor you didn’t plan to be here.

Three founders, one decision tree

The bootstrapper who might raise someday.You’re funding this from revenue for now, but venture is the plan if it works. Form the C-Corp on day one. The pass-through benefit you’re giving up is small at pre-revenue scale; the conversion you’re avoiding is not. An LLC here is a false economy.

The cash-flow founder who will never raise.Agency, consultancy, high-margin SaaS you intend to own outright and pay yourself from — the LLC (possibly with an S-Corp election) is legitimately the right tool. Pass-through works in your favor and nobody needs preferred stock. One honesty check before you commit: if there is any version of this where you sell to a buyer who wants a corporation, or take growth capital, the door you’re closing is expensive to reopen.

The lean AI founder.You need the C-Corp more than anyone. Large option pools to compete for engineering talent — native to C-Corps, awkward in LLCs. Clean IP assignment into a single corporate owner — the first thing AI diligence checks, and the thing training-data and model-IP questions make existential. A real corporate veil between you personally and the liability surface of a shipping AI product. And a governance framework needs an entity to attach to; investors now diligence AI governance at pre-seed, and “we’re an LLC, we’ll formalize later” reads as a company that hasn’t started being a company

What to do this week

If you’re venture-track, here’s a quick playbook for you:

1. Form the Delaware C-Corp. 
2. Issue founder stock and file your 83(b) within 30 days. 
3. Sign IP assignments and a founders’ agreement. 
4. Incase you missed last issue, check it out to know your archetype

A personal note

Dear Founder,

I've watched the same mistakes kill startups over and over after working with hundreds of founders across different business models.

Choosing your co-founder, and choosing your business structure are one of the first most strategic decision you will make.

Beyond your product, and your team — the business structure you choose is the vehicle investors have to trust enough to buy a seat in. A Delaware C-Corp is the vehicle they already trust. An LLC, for a venture-track founder, is a promise to rebuild structure mid-journey.

Pick once. Pick right. Navigation, not paperwork.

Thanks for reading! 🙏🏻
Please share with someone who would get value from this.
