1. Agreement to Terms

By accessing or using the Service, clicking "I Agree," or otherwise indicating acceptance of these Terms, you agree to be bound by these Terms and our Privacy Policy. If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms, and references to "you" or "Customer" shall refer to that organization. If you do not agree to these Terms, you must not access or use the Service.

You must be at least 18 years of age or the age of legal majority in your jurisdiction to use the Service. By using the Service, you represent that you meet this requirement.

2. Description of Service

GTMStack provides a go-to-market (GTM) operations platform designed to streamline and automate revenue operations workflows. The Service is available in two deployment models:

• Cloud-Hosted: A fully managed, multi-tenant software-as-a-service offering hosted and maintained by GTMStack on our cloud infrastructure.
• Self-Hosted (Enterprise): A licensable version of the platform that Customer may deploy and operate on its own infrastructure or private cloud environment, subject to the additional terms in Section 9.

The Service includes, but is not limited to, the following capabilities:

• SDR Operations: Tools for managing sales development representative workflows, lead routing, sequencing, and outbound campaign orchestration.
• Content Operations: Content creation, management, distribution, and performance tracking across GTM channels.
• Analytics: Dashboards, reporting, attribution modeling, and data visualization for GTM performance metrics.
• AI Automation: Machine learning and artificial intelligence features for workflow automation, lead scoring, content generation, and predictive analytics.

GTMStack reserves the right to modify, enhance, or discontinue features of the Service at any time, provided that material reductions in core functionality during an active subscription term will be communicated with at least thirty (30) days' prior notice.

3. Account Registration & Security

To use the Service, you must create an account by providing accurate, current, and complete registration information. You agree to update your account information promptly to keep it accurate and complete at all times.

You are responsible for:

• Maintaining the confidentiality of your account credentials, including passwords and API keys.
• All activities that occur under your account, whether authorized or unauthorized.
• Notifying GTMStack immediately at legal@gtmstack.app upon becoming aware of any unauthorized access to or use of your account.
• Implementing appropriate access controls when granting team members access to your organization's account, including role-based permissions and multi-factor authentication where available.

GTMStack will not be liable for any loss or damage arising from your failure to safeguard your account credentials. We reserve the right to suspend or disable accounts that we reasonably believe have been compromised.

4. Subscription Plans & Payment

The Service is offered through modular subscription plans that allow you to select and pay for the specific capabilities your organization requires. Pricing details for each module are published on our pricing page and may be updated from time to time.

• Billing Cycles: Subscriptions are available on a monthly or annual billing basis. Annual subscriptions are billed in advance for the full year and may include a discount compared to monthly billing.
• Payment Terms: All fees are due in advance and are non-refundable except as expressly provided in these Terms. Payment must be made via a valid credit card, ACH transfer, or other payment method accepted by GTMStack.

Such offers are subject to their own specific terms, are non-transferable, and apply only for the duration and scope expressly stated at the time of the offer. GTMStack reserves the right to modify or discontinue promotional pricing for new subscribers at any time without affecting existing promotional agreements.
• Price Changes: GTMStack may adjust subscription pricing upon thirty (30) days' written notice. Price changes will take effect at the start of your next billing cycle following the notice period. If you do not agree to a price change, you may cancel your subscription before the new pricing takes effect.

5. Free Tier & Trial

GTMStack may offer a free tier or time-limited trial of the Service, subject to the following terms:

• Limitations: Free tier and trial accounts are subject to usage limitations, including but not limited to restrictions on the number of users, contacts, API calls, data storage, and available features. These limitations are described on the applicable plan page.

• Self-Hosted Data: For self-hosted Enterprise deployments, Customer Data remains exclusively on the customer's own infrastructure.

The following additional terms apply to customers who license the self-hosted Enterprise version of the Service:

• License Grant: Subject to your compliance with these Terms and payment of applicable fees, GTMStack grants you a limited, non-exclusive, non-transferable, non-sublicensable license to install, copy, and operate the self-hosted version of the Service on your own infrastructure solely for your internal business purposes during the subscription term.

GTMStack reserves the right to withhold support for deployments running versions that are more than two (2) major versions behind the current release.
• Infrastructure Responsibility: You are solely responsible for provisioning, maintaining, and securing the infrastructure on which the self-hosted software operates, including but not limited to servers, networking, operating systems, databases, backups, disaster recovery, and compliance with applicable security standards.

• Rate Limits: API usage is subject to rate limits that vary by subscription plan. Rate limits are published in our API documentation and may be updated from time to time. Exceeding rate limits may result in temporary throttling or blocking of API requests.
• Fair Use: API access is provided for legitimate integration and automation purposes. You shall not use the API in any manner that places an unreasonable or disproportionate load on our infrastructure, degrades the experience for other users, or is inconsistent with the intended purpose of the API.
• API Key Security: API keys are confidential credentials. You are responsible for securing your API keys and must not embed them in client-side code, public repositories, or any other publicly accessible locations. You must rotate API keys immediately if you suspect they have been compromised. GTMStack reserves the right to revoke API keys that have been publicly exposed or are associated with abusive behavior.
• API Changes: GTMStack will use commercially reasonable efforts to maintain backward compatibility for API endpoints. Deprecated endpoints will be supported for at least six (6) months after deprecation notice. Breaking changes will be communicated at least ninety (90) days in advance where feasible.

12. Limitation of Liability

Liability Cap: To the maximum extent permitted by applicable law, the total aggregate liability of GTMStack arising out of or relating to these Terms or the Service, whether in contract, tort (including negligence), strict liability, or any other legal or equitable theory, shall not exceed the total fees actually paid by you to GTMStack during the twelve (12) months immediately preceding the event giving rise to the claim.

Exclusion of Indirect Damages: To the maximum extent permitted by applicable law, in no event shall GTMStack be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including but not limited to damages for loss of profits, revenue, goodwill, data, business opportunities, or anticipated savings, regardless of whether GTMStack was advised of the possibility of such damages and regardless of the cause of action or the theory of liability.

15. Termination

• Termination by Either Party: Either party may terminate these Terms and the associated subscription by providing thirty (30) days' prior written notice to the other party. For annual subscriptions, termination initiated by the customer mid-term does not entitle the customer to a prorated refund of prepaid fees unless otherwise specified herein.
• Termination for Breach: Either party may terminate these Terms immediately upon written notice if the other party materially breaches these Terms and fails to cure such breach within fifteen (15) days of receiving written notice specifying the breach. GTMStack may terminate or suspend your access immediately without notice in cases involving violations of the Acceptable Use Policy, threats to the security or integrity of the Service, or illegal activity.
• Data Export: Upon termination or expiration of your subscription, you will have a period of thirty (30) days to export your Customer Data from the Service. GTMStack will provide reasonable assistance with data export upon request. After the thirty (30) day export period, GTMStack may delete all Customer Data associated with your account in accordance with our data retention policies.
• Refund Policy: If GTMStack terminates your account for reasons other than your breach, you will receive a prorated refund of any prepaid fees for the unused portion of the subscription term. If you terminate your account or if GTMStack terminates for your breach, no refund will be issued for prepaid fees. Monthly subscriptions terminated by the customer will remain active through the end of the current billing period.
• Survival: Sections 7 (Intellectual Property), 8 (Customer Data & Privacy), 12 (Limitation of Liability), 13 (Indemnification), 14 (Warranty Disclaimer), 16 (Export Controls), 17 (Governing Law & Dispute Resolution), and 21 (Entire Agreement) shall survive any termination or expiration of these Terms.

16. Export Controls

The Service and any related technical data, software, or technology may be subject to United States export control laws and regulations, including the Export Administration Regulations (EAR) administered by the U.S. Department of Commerce, and economic sanctions programs administered by the U.S. Treasury Department's Office of Foreign Assets Control (OFAC).

You represent and warrant that: (a) you are not located in, organized under the laws of, or a resident of any country or territory that is subject to comprehensive U.S. sanctions (currently Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions of Ukraine); (b) you are not identified on any U.S. government restricted party list, including the Specially Designated Nationals and Blocked Persons List or the Entity List; and (c) you will not use, export, re-export, or transfer the Service in violation of any applicable export control laws or sanctions regulations. You agree to comply with all applicable export control and sanctions laws in your use of the Service.

17. Governing Law & Dispute Resolution

Governing Law: These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of laws principles.

Arbitration: Any dispute, controversy, or claim arising out of or relating to these Terms or the Service, including its formation, interpretation, breach, or termination, shall be resolved by binding arbitration administered by the American Arbitration Association ("AAA") in accordance with its Commercial Arbitration Rules. The arbitration shall be conducted by a single arbitrator in Wilmington, Delaware. The language of the arbitration shall be English. The arbitrator's award shall be final and binding, and judgment upon the award may be entered in any court of competent jurisdiction.

Injunctive Relief: Notwithstanding the foregoing, either party may seek temporary or preliminary injunctive relief or other equitable remedies in any court of competent jurisdiction to prevent irreparable harm, including but not limited to the unauthorized use or disclosure of proprietary information or trade secrets, without first submitting the matter to arbitration and without posting a bond or other security.

Class Action Waiver: You agree that any arbitration or proceeding shall be conducted only on an individual basis and not in a class, consolidated, or representative action. If for any reason a claim proceeds in court rather than in arbitration, both parties waive the right to a jury trial.

18. Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations under these Terms (other than payment obligations) to the extent that such failure or delay results from circumstances beyond the party's reasonable control, including but not limited to: acts of God, natural disasters, epidemics or pandemics, war, terrorism, riots, civil unrest, government actions or orders, labor disputes or strikes, fire, flood, earthquake, power outages, telecommunications failures, cyberattacks or distributed denial-of-service attacks on infrastructure beyond the affected party's control, or failures of third-party hosting or cloud service providers.

The affected party shall provide prompt written notice to the other party of the Force Majeure event and shall use commercially reasonable efforts to mitigate the impact and resume performance as soon as practicable. If a Force Majeure event continues for more than sixty (60) consecutive days, either party may terminate the affected portion of these Terms upon written notice without liability.

19. Modifications to Terms

GTMStack reserves the right to modify these Terms at any time. For material changes, GTMStack will provide at least thirty (30) days' prior notice through one or more of the following methods: email notification to the address associated with your account, a prominent notice on the Service, or a notification within the Service's administrative dashboard.

Material changes include, but are not limited to, changes that affect your rights or obligations, modifications to the limitation of liability or indemnification provisions, changes to the dispute resolution mechanism, or significant changes to how Customer Data is handled.

Your continued use of the Service after the effective date of any modifications constitutes your acceptance of the modified Terms. If you do not agree to the modified Terms, you must discontinue your use of the Service before the changes take effect. Non-material changes, such as typographical corrections or clarifications that do not alter the substance of the Terms, may be made without prior notice.

20. Severability & Waiver

Severability: If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction or arbitrator, such provision shall be modified to the minimum extent necessary to make it valid, legal, and enforceable while preserving its original intent. If modification is not possible, the provision shall be severed from these Terms. The invalidity, illegality, or unenforceability of any provision shall not affect the validity, legality, or enforceability of any other provision, and the remaining provisions shall continue in full force and effect.

Waiver: The failure of either party to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. No waiver shall be effective unless made in writing and signed by the waiving party. A waiver of any right or provision on one occasion shall not be deemed a waiver of such right or provision on any subsequent occasion.

21. Entire Agreement

These Terms, together with the Privacy Policy, any Data Processing Agreement executed between the parties, any Order Form or Statement of Work referencing these Terms, and any other documents expressly incorporated by reference herein, constitute the entire agreement between you and GTMStack with respect to the subject matter hereof and supersede all prior and contemporaneous understandings, agreements, representations, and warranties, both written and oral, regarding such subject matter.

In the event of a conflict between these Terms and any Order Form or Statement of Work, the Order Form or Statement of Work shall control solely with respect to the specific subject matter of that document. No terms or conditions contained in any purchase order, invoice, or other business document submitted by you shall modify or supplement these Terms, and any such terms or conditions are hereby rejected.
