Startup Legal Essentials — Foundations That Protect Your Company

Choosing Your Entity Structure

For venture-backed startups, a Delaware C-Corporation is the standard choice. Delaware offers well-established corporate law, a specialized Chancery Court, and predictable legal precedents. Investors expect it — many term sheets require Delaware incorporation. The filing costs are minimal ($89 state fee plus registered agent at $50-300/year).

LLCs work better for bootstrapped businesses, service companies, and real estate ventures. Pass-through taxation avoids double taxation, and operating agreements provide flexibility in profit distribution. However, LLCs cannot issue stock options (only units or profits interests), making them problematic for hiring with equity compensation.

S-Corporations suit small businesses with 1-5 owners who want pass-through taxation with liability protection. The 100-shareholder limit and single-class-of-stock restriction make S-Corps incompatible with venture capital. Many businesses start as LLCs, elect S-Corp taxation for payroll tax savings, then convert to C-Corps when raising institutional funding.

Founder Agreements and Vesting

A cofounder agreement is the most important document most startups never write. It should cover equity splits, vesting schedules, roles and responsibilities, decision-making authority, IP assignment, non-compete terms, and what happens if a founder leaves or is removed.

Standard vesting is 4 years with a 1-year cliff. This means a departing founder who leaves before 12 months gets nothing, then vests 25% at the cliff and 1/48th monthly thereafter. Vesting protects all founders from a cofounder who contributes for 3 months then disappears with 33% of the company.

Discuss the uncomfortable scenarios upfront: what if one founder wants to work part-time? What if you disagree on a major pivot? What if someone gets a job offer they cannot refuse? Documenting these scenarios when relationships are strong prevents lawsuits when relationships are strained.

Intellectual Property Protection

Every employee and contractor must sign an IP assignment agreement before writing a single line of code or creating any content. Without explicit written assignment, creators may retain ownership of work product under copyright law — even if you paid them to create it. This is the number one legal landmine for startups.

File provisional patents ($320 for small entities) for novel technology within 12 months of any public disclosure, use, or sale. Provisionals give you "patent pending" status and 12 months to file the full application while you validate market fit. Not all startups need patents, but all should make a deliberate decision about their patent strategy.

Trademark your company name and logo early. A federal trademark registration ($250-350 per class) prevents others from using confusingly similar names in your industry. Search the USPTO database before choosing your name — rebranding after building brand equity is enormously expensive.

Essential Contracts and Agreements

Terms of Service and Privacy Policy are required from day one if you collect any user data. GDPR, CCPA, and other privacy regulations impose significant penalties for non-compliance. Use reputable templates (Termly, iubenda) as a starting point, then have a lawyer review them for your specific data practices.

Customer contracts for B2B SaaS should cover: subscription terms and renewal, service level agreements (SLAs), data ownership and portability, limitation of liability, indemnification, and termination provisions. Keep liability caps reasonable — unlimited liability is a deal-killer for enterprise customers and an existential risk for startups.

Contractor agreements must clearly establish the independent contractor relationship (not employment), include IP assignment, define deliverables and payment terms, and address confidentiality. Misclassifying employees as contractors triggers back taxes, penalties, and potential lawsuits — the IRS examines the degree of control, not the label you apply.

Equity Compensation and 83(b) Elections

Stock options are the standard equity compensation for startup employees. Incentive Stock Options (ISOs) offer tax advantages for employees but are limited to $100,000 per year in exercisable value. Non-Qualified Stock Options (NSOs) have no limits but are taxed as ordinary income on exercise.

Founders who receive restricted stock must file an 83(b) election with the IRS within 30 days of receiving shares. This election lets you pay taxes on the current (low) value rather than the future (potentially much higher) vested value. Missing this deadline is one of the most expensive mistakes a founder can make — there are no extensions or exceptions.

Regulatory Compliance by Industry

Healthcare startups must comply with HIPAA for patient data, FDA regulations for medical devices or therapeutics, and state-specific telemedicine laws. Fintech companies face SEC, FINRA, and state money transmitter regulations. EdTech handling children's data must comply with COPPA. Identify your regulatory requirements before writing code.

SOC 2 compliance is increasingly required for B2B SaaS companies. Start building toward SOC 2 Type II from the beginning — implementing access controls, audit logging, change management, and incident response procedures. Retrofitting these controls into a mature product is 5-10x more expensive than building them in from the start.

Key Takeaways

• Delaware C-Corp is standard for venture-backed startups; LLCs suit bootstrapped businesses
• 4-year vesting with 1-year cliff protects all founders from early departures
• IP assignment agreements must be signed before any work begins
• File 83(b) elections within 30 days — there are no extensions or exceptions
• Build SOC 2 controls from the start; retrofitting costs 5-10x more
