A seed round is a startup’s first significant institutional fundraising event—the round at which outside investors provide capital in exchange for equity (or instruments that will convert into equity) to help the company move from idea to traction.
For Illinois startups, the seed round is a critical legal and financial milestone. Done right, it sets up a clean cap table, proper documentation, and the foundation for Series A readiness. Done wrong, it creates cap table messiness, investor disputes, and complications that can derail later fundraising.
What Qualifies as a Seed Round?
The term “seed round” is not a legal term—it’s an industry convention. It generally refers to:
- A company’s first formal raise from outside investors (beyond friends, family, and founders)
- Typically ranging from $250,000 to $3 million (though some seed rounds now reach $5M+)
- Usually structured as SAFE notes, convertible notes, or (increasingly) priced equity rounds with a pre-money valuation
- Investors include angels, angel groups, seed-stage VCs, and accelerators
Common Seed Round Structures
SAFE Notes (Simple Agreement for Future Equity)
The most common seed instrument for early-stage startups. SAFEs convert to equity at a future priced round, typically with a valuation cap and/or discount. No interest accrues, no maturity date. Fast to close, low legal cost. Standard YC SAFE documents are widely accepted in the startup ecosystem.
Convertible Notes
Debt instruments that convert to equity at a priced round. Bear interest (5–8% per year) and have a maturity date (18–24 months). More complex than SAFEs but preferred by some investors and in some industries. Convertible notes are debt on your balance sheet; SAFEs are not.
Priced Equity Round
Less common at seed stage but increasingly used for larger seed rounds ($2M+). Involves setting a pre-money valuation, issuing preferred stock, and executing full Series Seed documentation (term sheet, stock purchase agreement, investors’ rights agreement, voting agreement, right of first refusal agreement). More expensive legally but creates a cleaner cap table.

| Document | Purpose |
|---|---|

Pre-Seed Round Legal Housekeeping
Before closing a seed round, Illinois startups should have in place:
- A properly formed entity (Delaware C-Corp if VC-backed; Illinois LLC with potential conversion for bootstrapped/angel raises)
- Founder IP assignment agreements signed by all founders
- Founder equity properly documented with vesting schedules (and Section 83(b) elections filed if shares are subject to forfeiture)
- A clean cap table showing all outstanding equity and rights
- Basic employment or contractor agreements for anyone working on the product
Valuation Caps: Getting Them Right
For SAFE and convertible note raises, the valuation cap is the most important economic term. It determines how much of your company seed investors will receive when they convert.
A $5M cap means your seed investor converts as if they invested at a $5M valuation. If your Series A prices at $15M, they get 3x as many shares as a Series A investor for the same dollar amount. Setting the cap too low gives away too much equity; too high and angels won’t take the deal.
Typical Illinois seed round caps range from $3M to $8M for pre-revenue or early-traction startups in 2026.
FAQ: Seed Rounds for Illinois Startups
Do I need to be a Delaware C-Corp to raise a seed round?
Not necessarily for angel and seed raises. Some angel investors are comfortable investing in Illinois LLCs. But if you’re targeting institutional seed funds, most prefer or require a Delaware C-Corp structure.
Do I need a lawyer to close a seed round?
Yes. Even a SAFE round involves securities law compliance (Reg D exemption, accredited investor verification, Form D filing) that requires legal guidance. Mistakes in securities offerings can result in rescission rights for investors.
