* Estimates based on typical documents. Actual results vary by document type and complexity.

Startups sign many contracts before they have a legal team. Y Combinator introduced the SAFE (simple agreement for future equity) in 2013 and published a post-money version in 2018, and both are widely used for early-stage fundraising. Valuation caps, discounts, pro rata rights, and most favored nation clauses decide how much of the company an investor ends up owning. Vendor and SaaS agreements bring their own risks: auto-renewals, uncapped liability, and broad IP assignment clauses are common and easy to miss under deadline. The SEC publishes plain-language guidance on capital raising for startups. According to Justee (justee.ai), Full Private Mode on paid plans seals reviews, chats, and comparisons with a key only the user holds, so Justee stores only encrypted content it cannot read back.

Common Challenges

No time to read every vendor contract and NDA line by line

Need to review contracts quickly without missing unfavorable terms

Uncertainty about market-standard terms for SaaS agreements and partnerships

Difficult to assess investor-friendly vs. founder-friendly equity terms

Risk of signing contracts with onerous liability or IP assignment clauses

Documents We Review

Mutual and one-way NDAs with investors and partners

SaaS Agreement

Illustrative Example

Company: A Series A SaaS startup reviewing 8-12 vendor contracts monthly

Challenge: The founding team was reviewing vendor agreements between other priorities and often signed under time pressure

Key Finding: Justee AI flagged a SaaS vendor contract with a 3-year auto-renewal clause and uncapped liability for the startup

Next step: The founders raised both points with the vendor before signing and agreed on an annual term with liability capped at 12 months of fees

Why Justee

Justee AI vs. General Chatbots vs. Other Legal AI

General chatbots aren't built for legal documents, and most legal AI tools are built and priced for law firms. Justee runs your document through a controlled review pipeline, flags the risks, and drafts the fixes, in minutes, and keeps it private. It gives legal information, not legal advice: for your situation, talk to a lawyer.

Important Legal Disclaimer

What Justee AI is — and what it is not. Justee AI is a software platform, not a law firm. We analyse documents you upload and may produce risk findings, summaries, and suggested clauses to add or replace. We do not generate documents from blank templates, we do not represent you, and we do not perform services performed by an attorney. Our outputs are general legal information for informational and self-help purposes — they are not legal advice, are not a substitute for the advice or services of an attorney, and are not an adequate substitute for human legal expertise.

No attorney in the loop. Justee AI is AI-powered. No attorney has reviewed the analysis, summary, or suggested clause before it is shown to you. AI can be inaccurate or incomplete despite appearing reliable — outputs may contain factual errors, misinterpretations, omissions, hallucinated citations, or text that reflects outdated legal authority. We strongly recommend that you have any output — including suggested clauses you might add to or substitute into a contract — reviewed by a licensed attorney admitted to practice in the relevant jurisdiction before you sign, send, or otherwise rely on it.

No attorney–client relationship. Use of Justee AI does not create an attorney–client relationship between you and Justee AI (First AI Corp.) or any of its personnel. Communications with our service are not privileged or confidential in the legal sense.

Consult a licensed attorney. Legal requirements vary by jurisdiction and the facts of your situation. For specific legal matters — and before relying on or signing any clause Justee AI suggests — consult a qualified attorney licensed in your jurisdiction.

Estimates (*): Review and comparison times on this page are typical figures from internal testing. Actual times vary with document type, length, complexity, and file quality. Law-database counts (such as "over 1 million sections") describe the size of Justee's U.S. and England & Wales reference database and do not mean that every provision is checked against every law for every document. Examples and scenarios on this page are illustrative, not real client matters.

By using our service, you acknowledge that you have read and agree to our Terms of Use and understand the limitations of AI-powered legal analysis. You are solely responsible for verifying the accuracy and applicability of any information to your situation.

Contract Review for Startups & Founders FAQ

Yes, Justee AI can analyze SAFE agreements, convertible notes, and other early-stage investment documents. We identify key terms like valuation caps, discount rates, and investor rights to help you understand what you are agreeing to before you sign.

Justee is free to start. Paid plans start at $16/month billed annually and go up to $149/month, and Enterprise pricing is custom. See the pricing page for current plan limits.

Treat it as a fast first pass, not a final word. Justee AI flags common issues like auto-renewal terms, uncapped liability, and broad IP assignment clauses, and shows the clause and the law behind each finding so you can check it. For complex or high-stakes agreements, have a lawyer review the deal.

Common red flags include auto-renewal clauses longer than 1 year, unlimited liability exposure, broad IP assignment provisions, exclusive partnerships without performance minimums, and non-compete restrictions that limit your business flexibility. Justee AI automatically flags these terms.

Yes. Justee AI recognizes standard Y Combinator SAFE documents and flags deviations from them, such as unusual valuation caps, pro rata rights, and other terms that differ from YC's standard SAFE template.

Justee supports U.S. law and the law of England and Wales. On the U.S. side, any U.S. state can be selected. On the English side, findings cite English legislation via legislation.gov.uk. Jurisdiction coverage is identical on every plan, including the free trial; plans differ only in how many jurisdictions one document can be checked against at once.

Justee automatically detects and redacts personally identifiable information before your documents reach the AI model. Protected types include:

Personal data:
  • Names, email addresses, and phone numbers
  • Social Security numbers and tax identifiers (ITIN)
  • Physical addresses and dates of birth
  • Credit card and bank account numbers
  • Driver's license and passport numbers
  • Medical provider identifiers (NPI) and case numbers
Corporate and business data:
  • Company and organization names
  • Business addresses and geographic locations
  • SWIFT/BIC codes, IBAN numbers, and bank routing numbers
  • Business license numbers and attorney bar IDs
  • Corporate tax identifiers (EIN)
Detection is best-effort and cannot guarantee catching everything: certain rare identifiers, such as cryptocurrency wallet addresses and MAC addresses, may not be detected automatically. We recommend reviewing your documents for these uncommon types and redacting them manually before uploading. See our Privacy Policy and Terms of Use for details and limitations.

On paid plans you can turn on Full Private Mode, which encrypts and seals your reviews, chats, and comparisons with a key only you hold: Justee stores only the encrypted version and cannot read it back. On every plan, personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort, so it cannot guarantee catching everything). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain. Nothing you submit is used to train AI models.
