An Accelerators For Startups agreement is a legally binding contract between a startup accelerator program and a participating startup company that formally governs every dimension of the program relationship. It defines the funding the accelerator provides — whether cash stipend, SAFE, or convertible note — the equity or instrument the accelerator receives in exchange, the startup's program participation obligations, intellectual property and confidentiality terms, post-program reporting and information rights, and the accelerator's right to participate in future funding rounds. Unlike informal acceptance letters or term sheets, a properly executed accelerator agreement creates enforceable obligations on both sides and eliminates the ambiguity that routinely causes founder-accelerator disputes mid-cohort or at the next financing round.
Without a signed accelerator agreement in place before the cohort begins, both the accelerator and the startup are exposed in ways that materialize quickly. Accelerators that disburse stipends without a written repayment and forfeiture mechanism have no contractual basis to recover funds if a startup withdraws early. Equity that has not been formally documented by a signed instrument is not reflected on the cap table, creating confusion — and sometimes litigation — when the startup raises its seed round and new investors demand a clean cap table. Startups that participate without a written agreement have no protection against accelerators asserting broad IP claims based on verbal program commitments. Post-program, accelerators without information rights clauses receive no financial updates and cannot exercise pro-rata rights before they expire. This template gives accelerator operators a structured, attorney-reviewed starting point that covers all of these gaps — closing in under an hour what would otherwise take weeks of back-and-forth negotiation before each cohort.
| If your situation is… | Use this template |
|---|---|
| Accelerator takes a fixed equity stake at program entry | Accelerators For Startups (Equity Model) |
| Accelerator provides funding via a convertible note instead of equity | Convertible Note Agreement |
| Program offers mentorship only, with no equity or funding | Incubator Participation Agreement |
| Corporate accelerator requires IP licensing rather than assignment | Technology License Agreement |
| Startup receives a SAFE instead of equity or a note | Simple Agreement for Future Equity (SAFE) |
| Post-program follow-on investment with pro-rata rights | Seed Investment Agreement |
| Accelerator and startup establishing a joint venture | Joint Venture Agreement |
Why it matters: The accelerator's modeled ownership percentage is materially understated once option pools, SAFEs, and convertible notes are included in the cap table — creating a discrepancy that founders will dispute at the next funding round.
Fix: Define equity percentage explicitly on a fully diluted basis and attach a pro-forma cap table as an exhibit showing how the accelerator's stake is calculated.
Why it matters: Without measurable program obligations, the accelerator cannot terminate a non-participating startup for cause or withhold a second stipend tranche, leaving the program funding at risk.
Fix: Specify hours per week, required sessions, and milestone checkpoints in the body of the agreement — not in a separate program handbook that can be changed unilaterally.
Why it matters: Accelerators need cap table updates and financial data to exercise pro-rata rights before deadlines and to provide accurate portfolio reporting to their own investors and sponsors.
Fix: Include a 24–36 month information rights clause with specific deliverables (monthly financials, cap table on any new issuance, material event notices) and a delivery timeline for each.
Why it matters: In common-law jurisdictions, a startup already receiving program benefits has given no new consideration for the equity and IP clauses signed later — potentially voiding those provisions.
Fix: Execute all documents before or on the official program start date. If execution is delayed, provide documented additional consideration — an extra stipend payment or program benefit — at the time of late signing.
Why it matters: No credible accelerator requires IP ownership. Including such a clause signals unsophisticated drafting, deters experienced founders, and may void the agreement entirely if it is found to be unconscionable.
Fix: Limit the accelerator's IP rights to a narrow promotional license covering the startup's name, logo, and product description, with an explicit carve-out confirming the startup retains all other IP.
Why it matters: Immediate termination without notice gives a startup grounds to challenge removal as wrongful and seek recovery of equity already issued, creating litigation exposure for the accelerator.
Fix: Require written notice of the deficiency and a 5–10 business day cure window before termination becomes effective for any breach other than fraud or criminal conduct.
In plain language: Identifies the accelerator entity and the startup, states the program name and cohort cycle, and records the agreement effective date.
This Accelerator Program Agreement is entered into as of [DATE] between [ACCELERATOR LEGAL NAME], a [STATE] [ENTITY TYPE] ('Accelerator'), and [STARTUP LEGAL NAME], a [STATE] [ENTITY TYPE] ('Company'). Company is accepted into the [PROGRAM NAME] Cohort [NUMBER], commencing [START DATE] and concluding [END DATE].
Common mistake: Using the startup's trade name rather than its registered legal entity. If the entity name on the agreement differs from the cap table entry, equity issuance can be delayed or legally challenged.
In plain language: States the cash amount provided to the startup, the disbursement schedule, and any conditions precedent to receiving funds — such as signing, background checks, or entity formation.
Accelerator shall provide Company a program stipend of $[AMOUNT] USD, disbursed as follows: $[AMOUNT 1] on [DATE 1] and $[AMOUNT 2] on [DATE 2], contingent on Company's execution of this Agreement and completion of required onboarding steps.
Common mistake: Disbursing the stipend before all conditions precedent are satisfied. If a startup fails to complete entity formation or background checks, recovering unearned funds without a written repayment obligation is difficult.
In plain language: Defines the equity percentage the accelerator receives, the instrument used (common stock, preferred stock, SAFE, or convertible note), and the timeline for issuance.
In consideration of the program benefits provided, Company shall issue to Accelerator [X]% of Company's fully diluted capitalization in the form of [INSTRUMENT], to be issued within [30] days of the Agreement effective date, on terms set out in Schedule A.
Common mistake: Stating equity as a percentage of outstanding shares rather than fully diluted capitalization. Outstanding-only calculations exclude option pools and convertible instruments, so the accelerator ends up with a larger slice than modeled once the cap table is properly diluted.
In plain language: Clarifies that the startup retains ownership of its intellectual property and that the accelerator receives only a limited license to use the startup's name, logo, and description for promotional purposes.
Company retains all right, title, and interest in its Intellectual Property. Company grants Accelerator a non-exclusive, royalty-free license to use Company's name, logo, and product description solely to promote the Program and Accelerator's portfolio.
Common mistake: Including a broad IP assignment clause that transfers startup IP to the accelerator. No legitimate accelerator requires this, and it will deter sophisticated founders and their lawyers — or expose the accelerator to liability if the clause is later challenged.
In plain language: Establishes mutual confidentiality obligations covering the startup's business plans, technology, and financial information shared during the program.
Each party agrees to hold the other's Confidential Information in strict confidence and not to disclose it to any third party without prior written consent, except as required by law. 'Confidential Information' means any non-public technical, financial, or business information disclosed in connection with the Program.
Common mistake: Making confidentiality one-sided in the accelerator's favor only. Startups share sensitive IP and financial data during the program; mutual obligations protect both parties and make the agreement more credible to founders' advisors.
In plain language: Sets out what the startup must do during the program — attendance requirements, mentor sessions, progress check-ins, and milestone targets — and what happens if the startup fails to participate.
Company shall: (a) have at least one founder in residence at [LOCATION] or attending virtual sessions for no fewer than [X] hours per week; (b) complete all designated mentor sessions; and (c) present at Demo Day on [DATE]. Failure to meet participation requirements may result in termination under Section [X].
Common mistake: Leaving participation requirements vague. Without defined attendance and milestone standards, the accelerator has no contractual basis to terminate a non-participating startup or withhold a second funding tranche.
In plain language: Requires the startup to deliver financial statements, cap table updates, and material-event notices to the accelerator on a specified schedule after the program ends.
For [24] months following Demo Day, Company shall deliver to Accelerator: (a) unaudited monthly financials within [15] business days of month-end; (b) a current cap table within [5] business days of any equity issuance; and (c) prompt written notice of any Material Event, including a financing round closing or a change of control.
Common mistake: Omitting post-program information rights entirely. Accelerators need ongoing visibility into portfolio company performance to manage their own fund reporting and exercise pro-rata rights before deadlines expire.
In plain language: Grants the accelerator the right to participate in future funding rounds up to its pro-rata share, typically for a defined period after the program ends.
Accelerator shall have the right, but not the obligation, to invest in any future Qualified Financing of Company on the same terms as other investors, in an amount up to Accelerator's pro-rata share based on its then-current fully diluted ownership, for a period of [36] months following the Agreement effective date.
Common mistake: Failing to define a 'Qualified Financing' threshold. Without a minimum round size (e.g., '$500,000 or more'), the pro-rata right can be triggered by small bridge notes, creating administrative burden and potential deal friction.
In plain language: States the conditions under which either party may exit the agreement early, the notice required, and what happens to equity and any unspent stipend funds on early termination.
Accelerator may terminate Company's participation for Cause immediately upon written notice. 'Cause' includes material breach of this Agreement, fraud, or failure to meet participation requirements after [5] business days' written notice to cure. Upon termination for Cause, any undisbursed stipend tranche is forfeited, and Accelerator retains the equity already issued.
Common mistake: No cure period before termination for minor breaches. Immediate termination clauses without a notice-and-cure window expose the accelerator to wrongful-termination claims from startups that had a brief lapse in participation.
In plain language: Specifies which jurisdiction's law governs the agreement and whether disputes are resolved by arbitration, mediation, or litigation.
This Agreement is governed by the laws of the State of [STATE], without regard to conflicts-of-law principles. Any dispute arising out of or relating to this Agreement shall be resolved by binding arbitration administered by [AAA / JAMS] in [CITY, STATE], except that either party may seek injunctive relief in any court of competent jurisdiction.
Common mistake: Choosing a governing law state with no connection to either party's operations. Courts in some jurisdictions will apply local law regardless — particularly in Canada, the UK, and the EU — making a mismatch between stated law and operational reality a litigation risk.
Use the full registered legal name of the accelerator and the startup — not trade names or program brand names. Include the program name, cohort number, and exact start and end dates.
💡 Verify the startup's entity formation documents before execution. An agreement with an unformed or dissolved entity cannot be enforced against the founders personally without separate guarantee language.
Enter the total stipend, the tranche amounts, and the specific disbursement dates or triggering milestones. List every condition precedent to the first tranche — entity formation, background check, signed documents.
💡 Tie the second tranche to a midpoint milestone (e.g., completion of mentor sessions) rather than a fixed date. This gives the accelerator leverage if participation lags.
Choose the instrument — common stock, SAFE, or convertible note — and enter the exact percentage on a fully diluted basis. Attach the instrument as Schedule A with all relevant terms, including any valuation cap or discount rate.
💡 For SAFE or convertible note structures, confirm the valuation cap reflects current market benchmarks for your program's stage and sector to avoid founders rejecting terms as below-market.
Ensure the IP clause grants the accelerator only a promotional license — not an assignment or broad license. Review the confidentiality definition to confirm it covers both parties' sensitive information.
💡 Add a specific carve-out permitting the accelerator to share portfolio company details with its limited partners under a confidentiality obligation — this is standard in fund reporting.
List attendance minimums, required mentor sessions, check-in frequency, and any Demo Day obligations. Include the consequence — typically termination with forfeiture of undisbursed funds — for non-compliance.
💡 Define 'in residence' or 'virtual attendance' precisely. Vague presence requirements are the single most common source of founder-accelerator disputes mid-cohort.
Enter the reporting period (typically 18–36 months post-Demo Day), the reporting cadence, and the qualified financing threshold that triggers pro-rata rights.
💡 Set the qualified financing floor at a round size your portfolio companies realistically reach — $250,000 is too low for most accelerators; $500,000–$1,000,000 is more standard.
Confirm that termination for material breach includes a 5–10 business day cure period. Verify that the equity retention and stipend forfeiture mechanics on early termination are consistent with the disbursement schedule in the funding clause.
💡 Have both parties initial the termination clause separately to confirm they have read the forfeiture terms — this reduces disputes when a startup is later removed from the program.
Both parties must sign before the program begins. Post-start execution creates consideration problems in common-law jurisdictions and may invalidate key clauses, particularly IP restrictions and equity issuance obligations.
💡 Use a digital signature tool with a timestamp audit trail. Store the fully-executed copy in a secure document vault accessible to both parties.
An accelerators for startups agreement is a legally binding contract between a startup accelerator program and a participating startup that governs the terms of the engagement. It specifies the funding provided, the equity or instrument the accelerator receives in return, the startup's program obligations, IP and confidentiality terms, and post-program rights such as follow-on investment and reporting. It replaces informal program letters of intent with enforceable obligations on both sides.
Most accelerators take between 3% and 10% of a startup's fully diluted capitalization. Top-tier programs such as Y Combinator have historically taken approximately 7% in exchange for a standard funding amount. Corporate and university accelerators sometimes take 0% equity in exchange for fees or licensing arrangements. The percentage should always be stated on a fully diluted basis to avoid cap table disputes at the next financing round.
Accelerators run fixed-duration, cohort-based programs — typically 3 to 6 months — that culminate in a Demo Day pitch to investors. They almost always provide funding in exchange for equity. Incubators provide longer-term support (12–36 months), often with physical office space and mentorship, but typically do not take equity and do not operate on a cohort model. The agreements governing each are structurally different: accelerator agreements focus on equity terms and program obligations, while incubator agreements focus on space use, service terms, and milestone-based continuation.
For well-known programs with standardized terms — such as Y Combinator's SAFE or Techstars' standard docs — a founder can sign with a basic review. For any program using custom agreements, particularly those with unusual IP clauses, broad equity provisions, or corporate accelerators with strategic partnership obligations, engaging a startup attorney for a 1–2 hour review is strongly advisable. The cost is typically $300–$800 and can prevent equity or IP terms that follow the startup for its entire lifecycle.
If the startup is dissolved, the accelerator's equity interest is extinguished with the entity. Most accelerators do not have personal recourse against founders for equity value lost on a failed company. However, if the accelerator provided a convertible note rather than equity, the note becomes a debt obligation of the startup entity — though practically, recovery from a dissolved startup with no assets is rare. The agreement should explicitly state that the accelerator's investment is at-risk capital with no personal guarantee from founders.
Yes, typically by either party. Accelerators can terminate for cause — material breach, fraud, or non-participation — usually after a notice and cure period. Startups can withdraw, though withdrawal typically results in forfeiture of any undisbursed stipend tranches. The equity already issued is generally retained by the accelerator regardless of which party initiates early termination, since it represents consideration already received by the startup. Early termination mechanics should be fully specified in the agreement before signing.
Generally yes, but enforceability depends on the governing law specified and where the parties operate. In the US, accelerator agreements are routinely enforced under standard contract principles. In the EU, certain startup-protective regulations may override contractual terms — particularly around IP and information rights. Cross-border accelerator programs should specify governing law carefully and consider whether local employment-like regulations could recharacterize the startup-accelerator relationship in jurisdictions with strong founder-protection rules.
Demo Day is the pitch event at the end of the accelerator program where startups present to investors, press, and partners. The accelerator agreement should require attendance as a program obligation and grant the accelerator a license to record, stream, and distribute the startup's Demo Day presentation for promotional purposes. Startups should confirm the agreement's IP license covers Demo Day materials specifically and does not inadvertently grant rights to underlying product IP or source code.
A SAFE (Simple Agreement for Future Equity) converts to equity at a future priced round without accruing interest or carrying a maturity date, making it simpler and less administratively burdensome than a convertible note. A convertible note is debt that accrues interest and must be repaid or converted by a maturity date, creating a repayment obligation if the startup does not raise a qualifying round. Most modern accelerators use SAFEs or issue equity directly; convertible notes are more common in angel and bridge financing contexts outside formal accelerator programs.
A convertible note is a standalone debt instrument that converts to equity at a future financing round. An accelerator agreement is a comprehensive program contract that may include a convertible note as one component alongside program obligations, IP terms, and participation requirements. Use a convertible note alone for bridge financing; use an accelerator agreement when formalizing the full program relationship.
A seed investment agreement governs a direct equity investment with no program or participation obligations attached. An accelerator agreement ties the equity grant to program attendance, mentor sessions, Demo Day, and ongoing reporting obligations. If a funder is simply writing a check with no programmatic expectations, a seed investment agreement is the right document.
A joint venture agreement creates a new shared entity or ongoing commercial collaboration between two parties with aligned interests. An accelerator agreement is a one-directional support arrangement — the accelerator provides resources and funding; the startup participates and issues equity. A joint venture is appropriate when the accelerator and startup are co-developing a product or sharing revenue, not merely running a program.
A technology license agreement grants one party the right to use another's IP under specified conditions. In an accelerator context, a license agreement is appropriate when a corporate accelerator wants access to the startup's technology as part of the program rather than equity. An accelerator agreement with a built-in IP license clause is more appropriate when the program relationship involves both funding and limited promotional IP access.
Software IP ownership and open-source license compliance are critical; the agreement must confirm the startup retains all source code and proprietary algorithms with no accelerator license beyond promotional use.
Patent ownership, university technology transfer obligations, and regulatory milestone definitions require bespoke IP and milestone language that standard accelerator templates must be adapted to include.
Regulatory licensing status, data privacy obligations, and restrictions on sharing customer data with accelerator sponsors must be addressed explicitly in the confidentiality and information rights clauses.
Physical prototype ownership, manufacturing partnership introductions made by the accelerator, and export control compliance on dual-use technologies require additional representations and warranties not present in software-focused templates.
Brand license terms for accelerator co-marketing, retail partnership introductions, and supply chain introductions made during the program may create post-program obligations that should be addressed in the agreement.
Equity-for-funding models may be inappropriate for nonprofit entities; impact accelerators typically use grant agreements or revenue-share arrangements that require a structurally different agreement.
Accelerator agreements in the US are governed by standard contract law in the state of incorporation, with Delaware being most common for startup entities. SAFE instruments are widely accepted and largely unregulated at the federal level, though SEC exemptions (Regulation D, Rule 506(b) or 506(c)) must be confirmed before issuing any equity or convertible instrument. California-based accelerators should note that broad IP assignment clauses are limited by Labor Code §2870, which protects employee and contractor inventions developed without company resources.
Canadian accelerators should use an equity or SAFE structure consistent with provincial securities law exemptions — the 'accredited investor' or 'offering memorandum' exemptions are most common. Quebec-based programs must provide French-language versions of material documents under the Charter of the French Language. IP assignment clauses are generally enforceable, but courts have narrowed overbroad assignments that purport to cover inventions with no nexus to the company's business.
UK accelerator agreements typically use EIS- or SEIS-eligible structures to allow investors and accelerators to claim tax relief on qualifying investments. Equity issuance must comply with Companies Act 2006 share allotment requirements, and the accelerator's equity stake must be properly registered at Companies House. Post-Brexit, UK-based programs operating with EU startups should specify governing law carefully, as EU consumer and data protection rules may override UK contractual terms for EU-resident founders.
EU accelerator programs must comply with GDPR when collecting and processing startup founder data, including financial information and cap table details shared during the program. Equity instruments used by EU-based accelerators must comply with member-state securities regulations, which vary significantly — French PEA-eligible instruments differ from German GmbH share transfer requirements. Accelerators operating across multiple EU member states should obtain country-specific legal confirmation before executing agreements with startups incorporated in jurisdictions outside their home country.
