The 6 contracts that protect your startup from the start
Most startups don't fail because the idea was bad. A significant number run into serious trouble because they skipped the paperwork. A founder who leaves early but keeps 40% of the equity. A contractor who claims ownership of your core technology. A client who walks with your proprietary process and no legal recourse. The right contracts, signed at the right time, make those outcomes much less likely. Here's what you need and why.
1. Founders Agreement
If you're building with co-founders, this is the single most important document you'll ever sign — and it's the one most teams skip because "we trust each other."
A founders agreement (sometimes structured as a restricted stock purchase agreement or a co-founder agreement) covers:
- Equity split — how ownership is divided and on what basis
- Vesting schedule — the standard structure is four years with a one-year cliff, meaning no equity vests in the first year, then 25% vests at the one-year mark, with the remainder vesting monthly over the following 36 months
- IP assignment — all IP created for the startup is owned by the company, not by individual founders
- Roles and decision-making — who holds what title, who has final say on operational vs. strategic decisions
- Departure terms — what happens to unvested shares if a founder leaves voluntarily, is removed for cause, or becomes incapacitated
Why vesting matters so much
Investors call it "dead equity" — ownership held by someone no longer contributing to the company's success. When a founder exits unexpectedly in the critical early stages and takes a significant equity stake with them, it can be devastating. Most professional investors, including venture capitalists and angel investors, require founder vesting as a prerequisite for funding.
The math is unforgiving without it. Imagine three co-founders each receiving 33% of the equity with no vesting. After 6 months, one co-founder gets a job offer and leaves, keeping full 33% ownership while contributing minimal value. The remaining founders have to dilute themselves significantly to hire a replacement, while the departed founder collects dividend payments for years.
The 83(b) election — a deadline you can't miss
Founders receiving unvested equity must file 83(b) elections within 30 days of grant to avoid future tax complications. This allows taxation at grant date rather than vesting dates, which is critical for founders with significant unvested equity. Miss the 30-day window and it cannot be extended — full stop.

2. Non-Disclosure Agreement (NDA)
An NDA helps prevent others from sharing, stealing, or using your innovations without permission. When your startup is in its early stages, you'll discuss sensitive topics — business strategies, funding plans, product development, or customer data — with multiple parties. Having an NDA ensures that the people you talk to about your business can't disclose or use this information for their own gain.
You'll need two flavors:
| NDA Type | When to Use |
|---|---|
| One-Way (Unilateral) | You're disclosing to investors, vendors, or contractors — only one party shares sensitive info |
| Mutual | Both sides are sharing confidential information — partnerships, joint ventures, M&A discussions |
A one-way NDA is the most common type for startups. Many VCs and investors are unlikely to sign either type of NDA, especially early on, because they're not comfortable entering into confidentiality agreements unless discussions progress to a serious point. For early investor conversations, staged disclosure of information — sharing high-level details first — is often more practical than demanding an NDA upfront.
Federal law adds a required notice
The Defend Trade Secrets Act (DTSA) requires employers to include a notice in all employee NDAs and contractor agreements informing employees and contractors that they have immunity from liability for certain trade secret disclosures. If you fail to include this notice, you cannot recover exemplary damages or attorney's fees in a trade secret misappropriation lawsuit under the DTSA.
Use 2–5 years for the term and survival period (the typical industry standard). For trade secrets, specify that protection continues as long as the information remains a trade secret. Oral NDAs are difficult to prove and enforce — always have a written, signed NDA before disclosing confidential information. New to NDAs? Start with our primer on what an NDA is and how it works.

3. Independent Contractor Agreement
Hiring a freelance developer, designer, or consultant? A contractor agreement isn't optional — it's your primary tool for protecting your IP and avoiding worker misclassification liability.
The IP ownership trap
The biggest misconception is thinking you automatically own what you pay for. While employees' work typically belongs to the company, contractors generally retain ownership of their creations unless ownership is explicitly assigned in writing. Your agreement must include a clear IP assignment clause transferring all work product — code, designs, content, inventions — to the company.
Consider signing an IP assignment agreement with your employees and contractors in addition to an NDA. This way, you'll ensure that all the IP is assigned to your company and avoid issues during any investor due diligence.
Worker misclassification is a real risk
The U.S. Department of Labor's 2024 final rule uses a six-factor, totality-of-the-circumstances test under the FLSA. The factors include control, opportunity for profit or loss, investment, skill/initiative, permanence, and whether the work is integral to the business. Misclassifying a worker as a contractor when they function as an employee can trigger wage, tax, and penalty issues at both the federal and state levels.
A note on non-competes
As of September 2025, the nationwide FTC non-compete ban is officially dead. Following a series of injunctions from federal courts in Texas and Florida, the FTC voluntarily dismissed its appeal, meaning there is no federal rule prohibiting non-compete agreements across the country. Non-compete enforceability now depends almost entirely on your state. As of late 2025, four states maintain a near-total ban on non-compete agreements: California, Minnesota, North Dakota, and Oklahoma. Across the board, confidentiality and non-solicitation clauses are safer and more reliably enforceable than broad non-competes.

4. Master Services Agreement (MSA) + Statement of Work (SOW)
Once you're selling to other businesses — or buying from vendors and agencies — you need a contract structure that scales with the relationship.
A Master Services Agreement establishes the general, overarching legal terms between two parties. Instead of drafting a brand-new contract for each project, individual projects or Statements of Work can be attached later, each with specific deliverables, timelines, and costs. Think of an MSA as the "rules of the road" for the entire relationship.
The MSA sets up the general terms of your relationship — confidentiality, payment terms, liability, and that foundational stuff. The SOW comes in for specific projects. It details the exact work to be done, the deliverables, timelines, and project-specific costs. You'll have one MSA and potentially many SOWs over time.
What each document covers
| Document | Covers |
|---|---|
| MSA | IP ownership, liability caps, indemnification, warranties, confidentiality, governing law, dispute resolution |
| SOW | Specific deliverables, acceptance criteria, timeline, pricing, milestones, payment schedule |
MSAs provide three key advantages: they speed up future contract negotiations by eliminating the need to renegotiate standard terms, they create predictable business frameworks both parties can rely on, and they reduce legal costs for subsequent agreements.
For data-sensitive deals, your MSA should also address compliance with applicable data privacy laws such as GDPR, CCPA, and HIPAA, as well as cybersecurity standards and service-level agreements detailing expected uptime, response times, and remedies for service interruptions.

5. Website Terms of Service
Your Terms of Service (also called Terms of Use) are the rules users agree to when they access your product or website. They protect you from liability and define the scope of your relationship with users.
Terms of Service define the rules of using your platform. They include information on acceptable use, intellectual property rights, limitations of liability, pricing, payment terms, and dispute resolution. The purpose is to set clear expectations for users about your product or services and to protect the business from legal issues.
A solid Terms of Service document should cover:
- License grant — what users can and can't do with your platform
- Prohibited conduct — behaviors that warrant termination
- Intellectual property — who owns what (your IP stays yours; users keep their data)
- Limitation of liability — cap on damages you owe users
- Dispute resolution — arbitration, class action waiver, governing law
- Termination — how and when either party can end the relationship
6. Privacy Policy
In 2025, startups face a complex patchwork of privacy regulations: the EU's GDPR applies to any startup serving EU residents; California's CCPA/CPRA applies to businesses meeting revenue or data processing thresholds; and 20+ US state privacy laws create varying compliance requirements.
The practical reality for US-founded startups is that EU users arrive from day one — through organic search, product directories, and referrals — which means GDPR applies to those users regardless of where your company is incorporated or where your servers are located.
Your privacy policy must accurately describe:
- What personal data you collect (and from whom)
- Why you collect it (the legal basis under GDPR)
- Who you share it with
- How long you retain it
- User rights (access, deletion, correction, opt-out)
- How users can contact you with privacy requests
You must update your privacy policy every 12 months according to the CCPA/CPRA. Make sure to reflect this by updating your privacy policy's effective date even if you don't make any other changes.
Non-compliance with CCPA requirements can result in penalties reaching $7,988 per intentional violation, with additional civil lawsuit exposure under California's private right of action. GDPR fines can reach €20 million or 4% of global annual revenue.
If you work with vendors who process personal data on your behalf — analytics platforms, CRMs, email tools — you'll also need a Data Processing Agreement (DPA). A DPA is required under GDPR Article 28 for any vendor processing personal data on your behalf.

Contracts to add as you grow
As your team, revenue, and customer base expand, you'll also want:
- Separation Agreement — protects both sides when an employee or co-founder parts ways; covers IP, confidentiality, non-disparagement, and final compensation
- Services Agreement — a lighter-weight alternative to the full MSA/SOW structure for single-project client engagements
Common mistakes to avoid
- Skipping vesting because you trust your co-founder. Vesting isn't about distrust — it's about fairness and investor readiness. Apply it to everyone, including equal splits.
- Paying a contractor before the agreement is signed. Work started before a contract is executed may not be covered by your IP assignment clause.
- Using a generic NDA template without the DTSA immunity notice. Without this language, you lose the right to recover enhanced damages in a trade secret lawsuit.
- Launching with a copy-pasted privacy policy. A policy that doesn't reflect your actual data practices is worse than no policy — it's evidence of misrepresentation if you're ever investigated.
- Treating non-competes as a reliable safety net. Given state-by-state variation and ongoing FTC scrutiny, non-solicitation and confidentiality clauses are more defensible in most jurisdictions.
- Waiting until fundraising to get organized. Investors will surface all of these gaps during due diligence. Fixing messy equity tables and missing IP assignments mid-raise is expensive and stressful.

Frequently Asked Questions
When should a startup get its contracts in place?▾
Ideally, before you share any sensitive information, hire anyone, or sign a client deal. The founders agreement should be signed at or immediately after incorporation. NDAs go out before any confidential disclosure. Contractor agreements are signed before work begins. Waiting until 'we have revenue' is one of the costliest mistakes founders make.
Do investors really require a founders agreement with vesting?▾
Yes, virtually every serious investor — angels and VCs alike — will check for vesting schedules, IP assignment to the company, and a clear equity table during due diligence. Missing these protections is a common reason funding rounds stall or fall apart at the last minute.
Can I use a non-compete clause in my contractor or employee agreements?▾
It depends heavily on your state. As of September 2025, the FTC's nationwide non-compete ban was formally abandoned after federal courts blocked it, so enforceability is now entirely a matter of state law. California, Minnesota, North Dakota, and Oklahoma ban employee non-competes outright. In most other states, non-competes must be narrowly tailored in scope and duration to be enforceable. Confidentiality and non-solicitation clauses are generally safer and more widely enforceable alternatives.
Does my startup need a privacy policy even if we're small?▾
Almost certainly yes. The GDPR applies to any startup that handles data of EU residents regardless of company size or location. California's CCPA can apply once you hit certain data-volume thresholds. Beyond legal requirements, investors, enterprise customers, and app stores all expect a real privacy policy to be in place. Getting it right early is far cheaper than fixing a compliance gap during a due-diligence review.
What's the difference between an MSA and a services agreement?▾
A services agreement (or simple client contract) covers a single engagement end-to-end. A Master Services Agreement (MSA) sets the overarching legal terms for an ongoing relationship, then individual Statements of Work (SOWs) layer on the project-specific details — scope, deliverables, timeline, and price. The MSA-plus-SOW structure saves time and reduces friction when you work with the same clients or vendors repeatedly.
What happens if a contractor builds our core product without an IP assignment clause?▾
Without a written IP assignment, contractors generally retain ownership of what they create — even if you paid for it in full. Under U.S. copyright law, the 'work-for-hire' rule that automatically transfers ownership to employers does NOT apply to independent contractors the same way it does to employees. A signed contractor agreement with an explicit IP assignment clause is the only reliable way to ensure your company owns its own product.
