Terms of Service

Effective date: January 6, 2026 Last updated: January 6, 2026

1. Introduction and scope

These Terms of Service ("Terms") govern your access to and use of kastling.co and all sprint-based professional service engagements offered by Kastling ("Kastling," "we," "us," or "our"), a sole proprietorship based in Karachi, Pakistan.

By visiting kastling.co, submitting a project brief, or engaging Kastling for a service sprint, you agree to these Terms in full. If you do not agree, do not use our website or services.

These Terms cover Kastling Services: sprint-based, fixed-price professional service engagements for founders and operators.

Each Kastling in-house app (Verdikt, Capsule, Lanes, Triage) publishes its own Terms of Service on its own product website, which controls for app licensing, subscriptions, and payments.

2. Definitions

"Kastling," "we," "us," "our" means Kastling, a sole proprietorship based in Karachi, Pakistan.

"Services" means sprint-based professional service engagements as described below.

"Client" means any individual or entity that engages Kastling for Services.

"Deliverable" means any tangible or digital output produced by Kastling as part of a Services engagement.

"Sprint" means a fixed-scope, fixed-price, fixed-timeline Services engagement.

"You" means the Client.

3. Nature of services

Kastling offers professional service engagements across four pillars: AI Strategy, AI Engineering, AI Brand & Launch, and AI Operations. This spans AI product strategy and roadmaps, AI MVP and feature development, AI agents and workflow automation, brand identity and positioning, websites and launch assets, and ongoing AI operations.

All Services are structured as Sprints with a defined scope, fixed price, and agreed timeline. Kastling does not offer hourly retainers, open-ended consulting arrangements, or billable-hour relationships. Every engagement is outcome-based: a specific deliverable, on a specific date, for a specific price.

4. Engagement process

All Services engagements are initiated by the Client submitting a written project brief via kastling.co. Engagements are formalized through the following steps:

(a) Kastling reviews the brief and confirms fit within one business day where a potential engagement exists.

(b) A thirty-minute scope call defines the Sprint, the deliverables, and the definition of done.

(c) Kastling issues a written sprint proposal setting out scope, timeline, deliverables, and fixed price within forty-eight hours of the scope call.

(d) Client acceptance of the sprint proposal constitutes a binding agreement between the Client and Kastling. These Terms are incorporated by reference into every sprint proposal. Where a sprint proposal conflicts with these Terms, the sprint proposal governs.

5. Payment terms

Pricing is fixed at proposal. Payment terms, schedule, and accepted payment methods are specified in the sprint proposal. Payments for Services are transacted directly with Kastling.

Kastling does not issue invoices denominated in time. All pricing is scope-based and agreed before work begins.

6. Scope changes

Minor changes that fall within the agreed scope are absorbed by Kastling at no additional charge. Material changes to scope are documented in a written change order agreed by both parties before additional work begins, with a revised fixed price. Kastling does not issue unilateral change orders or surprise invoices.

7. Deliverables and intellectual property

Upon receipt of full payment for a completed Sprint, Kastling assigns to the Client all rights, title, and interest in the specific Deliverables produced for that Client under that Sprint, subject to the following:

(a) Kastling retains ownership of all pre-existing materials, tools, frameworks, methodologies, processes, and proprietary systems that Kastling incorporates into Deliverables. Kastling grants the Client a non-exclusive, perpetual, royalty-free license to use such materials as incorporated in the Deliverable.

(b) Kastling may reference completed engagements in its own portfolio, case studies, or marketing materials, unless the Client requests in writing that the engagement remain confidential.

8. Confidentiality

Kastling treats all Client-provided business information, product details, strategic materials, and non-public data shared in connection with a Sprint as confidential. Kastling will not disclose such information to third parties except:

(a) to vetted specialist collaborators engaged to execute the Sprint, who are bound by equivalent confidentiality obligations; or

(b) as required by applicable law or court order.

The Client agrees, on equivalent terms, to treat as confidential any of Kastling's proprietary methodologies, frameworks, internal processes, pricing structures, sprint proposals, and other non-public information shared in connection with a Sprint. These obligations are mutual and survive the completion or termination of any Sprint engagement.

9. Quality commitment and risk reversal

Kastling commits to delivering each first Sprint Deliverable in accordance with the scope agreed in the written sprint proposal and within the agreed timeline.

If the first Deliverable materially fails to meet the agreed scope, the Client may, within fourteen (14) calendar days of delivery, elect one of the following remedies:

(a) Full refund. A full refund of the Sprint fee paid.

(b) Sprint credit. A credit equal to the full Sprint fee applied to a follow-on Sprint.

The Client exercises this election by contacting Kastling at hello@kastling.co with a written description of how the Deliverable fails to meet the agreed scope.

This guarantee applies to the first Deliverable only. It does not apply where:

The Client materially changed scope after Sprint work began.
The project brief was materially incomplete, inaccurate, or misleading.
Failure results from the Client's own delay, non-response, or non-cooperation.
The Client's dissatisfaction relates to a stylistic or creative preference outside the agreed scope definition.

This commitment does not limit any other remedies available to the Client under applicable law.

10. Acceptable use

You agree not to use kastling.co or any Deliverable:

(a) for any unlawful purpose or in a manner that violates applicable law or regulation;

(b) to infringe, misappropriate, or violate the intellectual property rights of any third party;

(d) to attempt to gain unauthorized access to Kastling's systems, infrastructure, or any third-party system;

(e) to engage in any activity that disrupts, interferes with, or imposes an unreasonable burden on Kastling's operations or systems; or

(f) to misrepresent your identity or affiliation in connection with any Kastling service.

11. Kastling's intellectual property

14. Indemnity

You agree to indemnify, defend, and hold Kastling harmless from any claims, liabilities, losses, damages, and expenses (including reasonable legal fees) arising out of or related to: (a) your breach of these Terms; (b) your misuse of any Kastling service or deliverable; or (c) your violation of any third-party rights.

This indemnity does not apply where you act as a consumer (within the meaning of applicable consumer protection law) to the extent that such consumer protection law prohibits or limits indemnification by consumers.

15. Third-party services

16. Force majeure

Kastling is not liable for any delay or failure to perform its obligations where such delay or failure results from circumstances beyond Kastling's reasonable control, including natural disasters, acts of government, internet or infrastructure failures, or civil unrest. Kastling will notify you promptly and resume performance as soon as reasonably practicable.

18. Severability

If any provision of these Terms is found to be invalid, unlawful, or unenforceable under applicable law, that provision will be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible. The remaining provisions continue in full force.

19. Entire agreement

These Terms, together with any applicable sprint proposal, constitute the entire agreement between you and Kastling with respect to their subject matter and supersede all prior discussions, representations, or agreements.
