Terms of Service

01Acceptance of terms

These Terms of Service (“Terms”) govern your use of the Stack18 website and any services you order from Stack18 (“Stack18,” “we,” “us,” or “our”), together the “Services”. By using the Services you agree to these Terms. If you act for an organization, you confirm you can bind it. Where a signed order form or statement of work (“Order”) conflicts with these Terms, the Order controls for that engagement.

02Description of services

Stack18 offers:

• Agentic SDLC platform — an AI-native software lifecycle platform. The self-serve version is not yet generally available; separate terms will apply at launch.
• Pre-built Solutions — Commerce OS, Business OS, Customer OS, Supply Chain OS, FinOps OS and AI Enterprise OS, which we deploy, configure and customize for you.
• Technology Services — strategy, product engineering, AI transformation, modernization and growth technology.
• Enterprise Transformation Pod — a dedicated team combining the platform, solutions and services.
• Stack18 Ventures — our venture studio, which co-builds companies with founders and partners. Nothing on our website is an offer of securities or investment advice.

03Quotes, ordering and pricing

Prices shown on our website, including module “starting from” prices and estimated totals, are indicative, in Indian rupees, for one-time setup and configuration, and exclude GST and other applicable taxes. They are not an offer. A binding engagement exists only when both parties sign an Order describing scope, modules, deliverables, timeline and fees.

Where a module includes or depends on other modules, the Order records what is included. Custom work outside the selected modules is priced separately.

04Deployment on your infrastructure

Solutions and Enterprise deliverables are deployed on servers, cloud accounts or environments that you own or control. You are responsible for:

• Providing access, environments and cooperation we reasonably need.
• Infrastructure, hosting and third-party service costs and licences unless the Order says otherwise.
• Backups, monitoring and operations unless we agree to provide them as managed services.
• Your own users’ use of the deployed systems and your compliance obligations for them.

05Intellectual property

Customer ownership. Subject to payment of the fees due, you own the source code, configurations, designs, documentation and other deliverables created specifically for you under an Order (“Deliverables”), and all intellectual property rights in them. You also retain ownership of your data, content and pre-existing materials.

Stack18 materials. Stack18 retains ownership of the Agentic SDLC platform, internal tools, frameworks, templates, pre-existing code and know-how, and general skills and knowledge gained in delivering the Services (“Stack18 Materials”). Where Stack18 Materials are embedded in a Deliverable, we grant you a perpetual, worldwide, non-exclusive, royalty-free licence to use them as part of that Deliverable.

Third-party and open-source components stay under their own licences, which we identify to you. To the extent permitted by law, ownership extends to output produced with AI assistance as part of a Deliverable, and you are responsible for reviewing and approving it.

06Your data

You remain the owner and controller of the data in your environment. We use it only to deliver the Services and as our Privacy Policy and any data processing agreement describe. We do not use your source code or business data to train AI models without your written permission.

07Acceptable use

You must not use the Services to break the law, infringe others’ rights, distribute malware, attempt unauthorized access, or interfere with the Services or others’ use of them.

08Fees and payment

Fees, payment schedule and any late-payment charges are set out in the Order. Unless the Order says otherwise, fees are in Indian rupees, exclusive of GST and other taxes, which you pay in addition. Disputed amounts must be raised in good faith within a reasonable time of the invoice.

09Approvals and human oversight

Our delivery uses AI to execute work with human approval at defined gates, such as requirements, architecture and release. You are responsible for timely approvals and for reviewing critical outputs. Work proceeds on the basis of the approvals you give.

10Confidentiality

Each party will protect the other’s non-public information, use it only for the Services, and disclose it only to those who need it and are bound by similar duties, or as required by law. This continues after the engagement ends.

11Warranties and disclaimers

We will perform services with reasonable skill and care. Except as stated in an Order, the Services are provided “as is”. AI-generated output can contain errors, and we do not guarantee specific business results or uninterrupted operation. Estimates on our website are non-binding.

12Limitation of liability

To the extent permitted by law, neither party is liable for indirect, incidental or consequential loss, or loss of profit, revenue or data. Each party’s total liability under an Order is limited to the fees paid or payable under that Order in the twelve months before the claim. Nothing limits liability that cannot be limited by law.

13Term and termination

An Order runs for the term it states. Either party may terminate for material breach not cured within a reasonable period after written notice. On termination you keep the Deliverables you have paid for, and we will hand over the related code, documentation and access, and remove our access to your environment.

14Governing law and disputes

These Terms are governed by the laws of India. The parties will first try to resolve disputes in good faith. Failing that, the courts of competent jurisdiction in India have exclusive jurisdiction, unless an Order provides for arbitration.

15General provisions

These Terms and any Order are the entire agreement on their subject. If a provision is unenforceable, the rest remains in force. Delay in enforcing a right is not a waiver. You may not assign these Terms without our written consent. We may update these Terms; material changes are shown by the “Last updated” date and do not alter a signed Order.
