Startup bylaws: what they are and how they work

October 11, 2026

Bylaws are your corporation’s internal rulebook for how decisions get made: how many directors there are, how the board and stockholders meet and vote, which officers the company has, and how directors and officers are protected. The incorporator adopts them right after formation. They aren’t filed with the state, the board can usually amend them, and for an early-stage startup they’re largely standard.

Key takeaways

Bylaws cover procedure, not mission. A public benefit corporation’s purpose goes in its certificate of incorporation, not its bylaws.
Bylaws are private and stay in your minute book.
The board can amend them if the charter allows it, and almost every startup charter does.
Follow them. Actions taken in violation of the bylaws can be challenged as invalid.

Charter, bylaws and stockholder agreements: what’s the difference?

Three documents set how a Delaware startup is governed, each inside the limits of Delaware’s corporation statute:

The certificate of incorporation (charter) is filed with the state. It sets the company’s name, authorized shares, the rights of each class of stock and any public benefit purpose. See Certificate of Incorporation.
The bylaws are internal and set the procedures. They must be consistent with the statute and the charter.
Stockholder agreements, such as a voting agreement after a priced round, can add rules on board seats and approvals. Since 2024, Delaware expressly allows these agreements to limit what the board can do without certain stockholders’ consent.

What’s in a standard set of startup bylaws?

Section	What a typical startup version says
Offices	The registered office is set in the certificate of incorporation. The board can open other offices where the company is qualified to do business.
Stockholders	When and how stockholders meet (including remotely), notice, quorum and voting. Stockholders can act by written consent instead of meeting.
Board of directors	The board or the stockholders set the number of directors by resolution, unless the charter fixes it. A majority of directors in office is a quorum. The board can act by unanimous written consent and meet by phone or video.
Committees	The board can create committees. Most startups have none before a Series A.
Officers	A president and a secretary are required. The board can also appoint a CEO, CFO, treasurer and others, and one person can hold more than one office.
Indemnification	The company protects directors and officers from claims to the fullest extent Delaware law allows and advances their legal fees.
Records and stock	The company keeps a stock ledger and minutes, and shares can be uncertificated.
Amendment	Who can change the bylaws and how.

Are bylaws filed with the state?

No. The incorporator adopts them in the action of incorporator, and they stay in the company’s minute book. That’s why they can be changed without a filing. See Action of Incorporator.

Who can amend the bylaws?

Under Delaware law, stockholders can always amend the bylaws, and the board can too if the charter gives it that power, which almost every startup charter does. In practice the board makes the changes by written consent. After a priced round, preferred investors usually must also approve bylaw amendments that affect their rights. See What Do Stockholders Need to Approve?

What happens if we don’t follow them?

An action taken without following the bylaws, such as a board decision made without proper notice or quorum, can be challenged as invalid. Missteps usually surface in due diligence before a financing or a sale, and many can be fixed by having the board or stockholders ratify the action afterward. It’s easier to follow the procedure the first time: use written consents and keep them in the minute book.

Are bylaws from Clerky or Stripe Atlas fine?

Generally yes, for an early-stage company. Platform bylaws are standard Delaware forms. Have a lawyer review them alongside the rest of your formation documents before your first priced round, since investors may ask for changes.

Are bylaws different for a public benefit corporation?

Barely. A public benefit corporation’s specific public benefit belongs in its certificate of incorporation, and its reporting duty comes from the statute. Some benefit corporations add a board committee that oversees the mission, which is a bylaw provision. See Public Benefit Corporation.
