Master SAFEs, convertible notes, shareholder agreements, and investor rights to close your funding round efficiently without legal surprises.
Vlad Cazacu
Before raising capital, you need to understand four categories of legal elements: the fundraising instruments you'll use to accept investment (SAFEs, convertible notes, or priced equity rounds), the corporate documents that define your company structure (Articles of Incorporation, Shareholder Agreements), the rights and obligations embedded in any previous fundraising rounds that still bind you today, and the structural decisions around entity type, cap table management, and equity allocation that affect your ability to raise and your attractiveness to investors.
Most founders are dangerously unclear about the legal foundation that informs long-term success. A seed-stage founder who forgot about Rights of First Refusal from their pre-seed round can't execute a term sheet with a new lead investor without first offering those shares to existing investors. A founder using the wrong corporate structure may discover mid-fundraise that institutional investors simply cannot invest in their company type. Understanding your legal foundation isn't optional preparation - it's the difference between closing your round efficiently and watching it collapse due to preventable structural problems.
The good news: legal preparation follows a predictable pattern. Know which fundraising instrument matches your stage, understand what rights you're granting investors, maintain organized records of all agreements, and work with experienced startup counsel at critical junctures. Founders who master these fundamentals move through fundraising with confidence, while those who ignore legal basics waste months untangling problems that proper preparation would have prevented entirely.
A SAFE is neither debt nor equity - it's an agreement giving investors the right to future equity at an approximate valuation instead of an exact one. Y Combinator pioneered SAFEs over a decade ago, and they've become the standard instrument for pre-seed and seed rounds, with roughly 95% of pre-seed raises using them.
SAFEs work through two key mechanisms: a valuation cap (the maximum valuation at which the SAFE converts to equity) and a discount rate (typically 15-20%, giving SAFE holders a discount when converting compared to the price new investors pay). When you raise a priced equity round later, SAFE holders convert their investment into shares at whichever is more favorable - the valuation cap or the discounted price of the new round.
The primary advantage of SAFEs is simplicity. Unlike convertible notes, SAFEs don't appear on your balance sheet, don't accrue interest, and don't have maturity dates creating artificial pressure. They're streamlined documents that let you close investments quickly without extensive negotiation. The timeline for deployment is uncertain at pre-seed and seed stages - you might raise your Series A in 12 months or 36 months, and SAFEs accommodate this uncertainty without penalty.
When to use SAFEs: Pre-seed and seed stages where you cannot reasonably assign an exact valuation and need maximum flexibility. If you're raising smaller checks ($25K-$100K) from angels and early-stage funds, SAFEs are your default instrument.
Convertible notes are debt instruments that accrue interest and convert to equity at a future priced round. Unlike SAFEs, they have maturity dates (typically 18-24 months) and interest rates (typically 5-8%), and they appear on your balance sheet as liabilities until conversion.
The investor-friendly nature of convertible notes makes them more favorable to investors than SAFEs – they have the right to be repaid at maturity if no conversion event occurs. This creates risk for founders: if you don't raise a priced round before maturity and can't repay the note, you face difficult conversations about extensions or face default.
Convertible notes make sense in exactly one scenario: clear bridges between priced rounds. If you're six months from closing your Series A and need $500K to extend runway, a convertible note with a 12-month maturity works because everyone involved has high certainty about the conversion timeline. In all other scenarios, the compounding interest works against you (turning an already-expensive SAFE into an even more expensive one), and the maturity date creates artificial pressure that rarely benefits founders.
When to use convertible notes: Only when you have absolute certainty a trigger event will happen before maturity and both parties view this explicitly as bridge financing, not as a standalone investment round.
Priced equity rounds involve selling preferred stock at a specific price per share, establishing an explicit company valuation. These rounds come with term sheets negotiating specific investor rights, board composition, liquidation preferences, and protective provisions. Priced rounds typically begin at Series A, though some later-stage seed rounds are priced.
The sophistication required for priced rounds is significantly higher than SAFEs. You'll negotiate a term sheet with your lead investor, defining the specific rights of the preferred stock class being created. Your existing investors' Shareholder Agreement will be amended or restated to incorporate the new investor class. The process involves extensive legal documentation and typically costs $25K-$75K in legal fees depending on complexity.
When to use priced rounds: When you have sufficient traction and scale to justify specific valuation (typically $1M+ ARR or equivalent product/market traction), when you're raising $2M+ from institutional investors who require the structure and governance of preferred stock, and when you've exhausted the SAFE/note pathway and need the clarity of explicit equity ownership.
Your Shareholder Agreement is the primary contract with investors, containing the majority of specific rights granted to shareholders. This document governs ongoing relationships between the company and investors, including Rights of First Refusal (existing investors' right to buy shares before new parties), preemptive rights (existing investors' right to maintain ownership percentage in new rounds), co-sale rights, drag-along rights, protective provisions (actions requiring investor consent), and transfer restrictions.
When reviewing Shareholder Agreements – especially from previous rounds – focus on sections titled "Investor Rights," "Transfer Restrictions," "Preemptive Rights," and "Consent Requirements." These clauses remain in effect through subsequent rounds unless explicitly modified, meaning rights granted in your seed round still bind you during Series B.
Amendments modify original Shareholder Agreement terms and may add entirely new rights that didn't exist in the base document. Never review only the original agreement without checking for amendments – you'll have an incomplete understanding of your current obligations. Amendments are typically titled "First Amendment to Shareholder Agreement" or "Amendment No. 2" and should be stored immediately following the base agreement they modify in your data room.
Your Articles define your company's fundamental legal structure, including different classes of stock (common vs. preferred), voting rights, and share characteristics. Articles are filed with your state of incorporation and updated with each equity round as new preferred stock classes are created. These documents must be included in your data room for investor due diligence.
These individual contracts record the specific terms of each investor's purchase – who bought how many shares at what price on what date. While less likely to contain ongoing governance rights compared to Shareholder Agreements, these documents are essential for confirming cap table accuracy and maintaining complete corporate records.
Rights of First Refusal give existing investors the contractual right to purchase shares before new parties can buy them. RFRs typically apply either to founder share transfers (if you personally want to sell shares) or to new shares the company issues in future rounds. Understanding exactly who holds RFRs, how they're triggered, and the timeline for exercising them prevents you from promising shares to new investors that you're legally obligated to offer existing investors first.
The practical implication: if you negotiate a term sheet with a new lead investor for 20% ownership, but your existing investors exercise their RFR, the allocation available to your new lead shrinks. This affects your timeline, negotiating leverage, and potentially whether your preferred lead can participate at their desired level.
Preemptive rights allow existing investors to invest in your current round to maintain their ownership percentage, preventing dilution. If your seed investor owns 15% and has preemptive rights, they can invest enough in your Series A to maintain that 15% ownership rather than being diluted down to 8-10%.
These rights reduce the equity available to new investors. Before negotiating with new investors, understand which existing investors hold preemptive rights and their likely intention to exercise. Some investors always exercise their pro rata, others rarely do –knowing your specific investors' patterns helps you model realistic allocation scenarios.
Protective provisions require existing investor consent (often supermajority vote of a specific share class) before the company can take certain actions. Common protective provisions include raising new financing on specific terms, changing the Articles, issuing new shares of certain types, or making fundamental business changes like acquisitions or dissolutions.
Discovering mid-negotiation that you need prior investor approval for proposed term sheet terms creates delays and potentially forces renegotiations, weakening your position with both new and existing investors. Review protective provisions from all previous rounds before beginning fundraising conversations to understand your constraints upfront.
The overwhelming majority of venture-backed startups are Delaware C Corporations, and for good reason. Delaware offers the most established business law framework, making it attractive to institutional investors. While you can technically raise venture capital as an LLC or in other states, institutional investors strongly prefer Delaware C Corps due to legal precedent, favorable corporate law, and standardized structures they understand.
If you're currently an LLC or incorporated in another state, consider converting to a Delaware C Corp before fundraising. There are three primary conversion methods: statutory conversion in your current state, statutory merger in your current state, or statutory merger in Delaware. Your legal counsel can advise on the most tax-efficient approach for your situation.
Key Delaware C Corp considerations:
When raising $100K+ from multiple angel investors writing $5K-$25K checks each, consider using a Special Purpose Vehicle (SPV). An SPV is an LLC entity where all angels invest together, consolidating their investments under one line on your cap table instead of 10-20 individual entries.
The mechanics: each angel wires funds into the SPV's bank account, and once the SPV closes (all investors have contributed), the SPV entity invests in your company via a single SAFE. As the SPV manager, you retain voting rights while angels receive economic benefits and rights without individual voting power. This dramatically simplifies cap table management and future investor communications.
Cost-effectiveness threshold: SPVs involve setup costs (typically $3K-$8K through platforms like AngelList), so they're only worthwhile when consolidating $100K+ in small checks. Below that threshold, individual SAFEs make more sense despite the cap table complexity.
Key limitation: You can only collect funds once the SPV closes – all angels must wire before you can liquidate the entity and transfer capital to your operating account. This requires more coordination than accepting individual investments as they come in, but the long-term cap table benefits typically outweigh the short-term administrative burden.
Your cap table is the living record of who owns what percentage of your company. Maintaining an accurate, organized cap table isn't optional – it's fundamental to fundraising, as investors will scrutinize ownership structure during diligence.
409A valuations and option pricing: For early-stage companies without significant revenue or a priced round, your company's fair market value for option issuance purposes is typically set at par value (often $0.00001 per share). This low exercise price benefits early employees who don't pay significant amounts to exercise their options. The SAFE cap doesn't hold weight in calculating FMV during 409A valuations until you raise a priced round or generate meaningful revenue.
Employee Stock Option Plans (ESOPs): Once shares or options are issued under an ESOP, employees can exercise them at the price set at issuance, even if market value increases later. The exercise price isn't specified in the ESOP plan itself but in individual option agreements, locking in the price. Early equity issuance at low valuations significantly benefits employees.
Timing considerations: Issue founder and early employee equity early while valuations are minimal. Delaying equity issuance forces later employees to purchase shares at higher fair market values, reducing the attractiveness of equity compensation.
Certain legal work requires experienced startup counsel, while other tasks can be handled with standard templates and platforms.
Always use legal counsel for:
Templates and platforms work for:
Budget allocation: Expect $25K-$75K in legal fees for a priced equity round, $5K-$15K for LLC-to-C-Corp conversion, and $2K-$5K for pre-fundraise document review. These aren't optional expenses – they're investments in avoiding significantly more expensive problems later.
Ignoring previous round obligations: Founders negotiate new term sheets without reviewing old Shareholder Agreements, discovering too late that protective provisions require existing investor consent for proposed terms. This breaks momentum and signals poor attention to detail.
Poor cap table hygiene: Messy cap tables with unresolved discrepancies, missing documentation, or confusion about who owns what raise massive red flags. Investors view cap table disorganization as a proxy for overall operational sloppiness.
Wrong corporate structure: LLCs and non-Delaware entities limit your investor pool. Waiting until mid-fundraise to address structure wastes time and creates gaps in your timeline when you should be building momentum.
Verbal commitments without documentation: Angel investors verbally commit but never wire funds. Always follow verbal commitments with written confirmation emails specifying amount and timeline.
Misunderstanding SAFEs vs. convertible notes: Founders issue convertible notes without certainty about conversion timing, creating maturity pressure. Or they issue SAFEs with overly generous terms that make subsequent rounds difficult.
Forgetting about SPV timing: Accepting small checks individually when an SPV would have been more efficient, or setting up an SPV then discovering you needed immediate capital access before the SPV could close.
Before raising your next round, allocate 2-4 weeks to review all documents from previous fundraising events. This isn't optional preparation – it's discovering constraints before they become surprises.
What to review: Shareholder Agreements from each previous round, all amendments to those agreements, current Articles of Incorporation, equity purchase agreements, and any side letters with specific investors.
What to look for: Rights of First Refusal (who can buy shares before new investors), protective provisions (what actions require existing investor consent), preemptive rights (who can participate to maintain ownership percentage), and any unusual or non-standard terms.
How to approach it efficiently: Organize a comprehensive data room with documents sorted by round in clearly labeled folders. Use digital search (Ctrl+F) for terms like "Right of First Refusal," "Preemptive," "Consent," and "Protective Provisions" rather than reading every word. Work with your startup lawyer to prepare a summary of flagged provisions and discuss practical implications for your current fundraise.
The goal isn't memorizing every clause – it's understanding which historical commitments constrain your current raise and having that knowledge before negotiating with new investors.
A SAFE is an agreement for future equity with no maturity date, no interest accrual, and no balance sheet impact. A convertible note is debt that accrues interest, has a maturity date requiring repayment if no conversion occurs, and appears on your balance sheet as a liability. SAFEs are founder-friendly instruments for uncertain timelines, while convertible notes work only as clear bridges between priced rounds when conversion timing is certain.
Convert before approaching institutional investors. While angels may invest in LLCs, venture capital funds and institutional investors strongly prefer Delaware C Corps due to legal precedent and standardized structures. Complete the conversion before fundraising begins to avoid gaps in your timeline and signal operational sophistication.
Use an SPV when consolidating $100K+ in checks from multiple angels each investing $5K-$25K. Below $100K total, individual SAFEs make more sense despite cap table complexity because SPV setup costs ($3K-$8K) aren't justified. Above $100K, the long-term cap table benefits and simplified investor communications outweigh setup costs.
You must honor the RFR even if you already negotiated with a new investor. This creates awkward conversations where you must offer shares to existing investors first, potentially reducing allocation available to your new lead. The solution is proactive review of previous agreements before making commitments to new investors, not reactive crisis management.
Standard SAFEs to angel investors can use Y Combinator's template documents without customization, making lawyers optional for simple issuances. However, if you're negotiating terms, dealing with unusual investor requests, or uncertain about provisions, spending $1K-$2K for legal review prevents expensive mistakes. Never negotiate priced rounds or complex structures without legal counsel.
Review documents from every equity financing round in your company's history, including your first institutional raise or significant angel round. Even seed round agreements from three years ago contain rights that still bind you today. Convertible notes or SAFEs that converted in previous rounds matter less since conversion typically extinguished those agreements, but review conversion terms to understand what preferred stock resulted.
Protective provisions require existing investor consent (often supermajority vote) before you can take certain actions, including raising new financing on specific terms, changing Articles, or making fundamental business changes. They matter because your new round's proposed terms may trigger protective provisions, requiring you to obtain existing investor approval before closing. Discovering this requirement mid-negotiation delays your fundraise and weakens your position.
Renegotiation is possible but risky and requires existing investor cooperation. Only renegotiate genuinely problematic terms that will significantly impact your current raise – extremely onerous protective provisions, unusual rights that new investors view as red flags, or terms inappropriate for your current maturity. Offer something in exchange rather than simply asking investors to give up rights, and only when absolutely necessary since reopening closed agreements creates uncertainty.
Organize folders by financing round (Seed, Series A, etc.) containing Shareholder Agreements, all amendments, Articles after each round, equity purchase agreements, board consents approving rounds, and cap tables as of each round's close. Include a master folder with current Articles, current cap table, and a lawyer-prepared summary explaining key terms' evolution across rounds. Clear organization signals operational sophistication.
Preemptive rights reduce equity available to new investors if existing investors exercise their rights to maintain ownership percentages. Understanding which investors hold these rights and their likely intention to exercise helps you model realistic allocation scenarios before negotiating with new leads. Some investors always exercise pro rata rights, others rarely do – knowing your specific investors' patterns prevents over-promising to new investors.
Common Stock is issued to founders and employees with standard voting and economic rights. Preferred Stock is issued to investors in priced rounds and includes additional rights like liquidation preferences (getting paid before common stockholders in exits), anti-dilution protection, and board representation rights. Start with only Common Stock; Preferred classes are created when VCs invest and co-negotiate terms with you.
Issue early employee equity immediately while your company's fair market value is minimal (often par value of $0.00001 per share). This creates extremely low exercise prices benefiting employees significantly. Delaying equity issuance forces later employees to purchase shares at higher FMV after you've raised capital or generated revenue, reducing equity compensation attractiveness.
Delaware calculates franchise tax based on either authorized share count or gross assets, whichever results in lower tax. With minimal assets (under $50K), you'll pay roughly $400 annually regardless of share count. As your balance sheet grows, the calculation matters more. Most startups authorize 10 million shares initially and pay minimum tax until later stages when assets increase.
Contact your legal counsel from that round (law firms maintain client files for years), reach out to investors from those rounds for their copies, check email archives, and look through your corporate secretary's records. If documents are truly lost, your lawyer may need to reconstruct terms based on standard forms from that timeframe, but this is suboptimal. Missing documents create serious diligence problems – in worst cases, existing investors may need to re-execute lost agreements.
Update your cap table immediately after every equity transaction: SAFE issuances, option grants, option exercises, and equity rounds. Use cap table management software (Carta, Pulley, AngelList) rather than spreadsheets to prevent errors and maintain audit trails. Investors will scrutinize cap table accuracy during diligence – discrepancies raise red flags about operational competence.
Legal preparation isn't bureaucratic box-checking – it's the foundation that determines whether you can efficiently close your round or spend months untangling preventable problems. Founders who master fundraising instruments, understand their previous commitments, maintain organized corporate records, and work with experienced counsel at critical junctures move through fundraising with confidence and credibility.
The pattern is consistent: sophisticated founders proactively review their legal foundation, organize comprehensive data rooms, understand exactly which rights they've granted and which obligations they've assumed, and approach new investors from a position of clarity rather than uncertainty. These founders close rounds faster, negotiate from stronger positions, and avoid the momentum-killing surprises that derail less-prepared competitors.
Your legal structure is permanent in ways your pitch deck isn't. A poorly negotiated Shareholder Agreement or forgotten protective provision affects not just your current round but every subsequent financing event in your company's life. The time invested in understanding legal fundamentals compounds across every future fundraising conversation, every new investor relationship, and ultimately, your success in building a fundable, scalable company. Start with clarity, maintain organization, and treat legal infrastructure with the same importance you give product development and customer acquisition – because without proper legal foundation, neither product nor customers matter to institutional investors who won't bet on structurally flawed companies.
