Terms of Service

Agreement

These Terms of Service ("Terms") govern access to kulissa.com and the Kulissa product. By creating an account, signing an order form, or using the Maya demo, you agree to them. If you accept on behalf of a company, you confirm you are authorised to bind that company ("Customer").

The contracting entity is STEALTH, trading as Kulissa, operated by the founding team pending incorporation, reachable at hello@kulissa.com, Paris and Zurich. Entity fields marked STEALTH are replaced when incorporation completes.

A signed Order Form or Data Processing Agreement prevails over these Terms where they conflict on the same subject. The Privacy Policy, DPA, Acceptable Use Policy and AI Transparency notices form part of this agreement by reference.

The service

Kulissa provides AI-assisted voice roleplay and coaching software: scenarios generated from Customer material, live practice sessions with an AI buyer, transcripts, scored debriefs and manager workspaces. Features available to a Customer are those listed in its Order Form and plan.

We may improve the service. Material reductions of an engagement's core capabilities will be announced in advance.

Accounts and access

Customer designates administrators who invite users. Each user must keep credentials confidential. Customer is responsible for activity under its accounts and for ensuring users are authorised (typically employees or contractors).

We may suspend an account that compromises security or violates the Acceptable Use Policy, and will notify Customer unless law forbids it.

AI credits

AI credits are the entitlement unit for billable AI actions (practice sessions, assistant conversations, generated scenarios and similar product actions described in the product). Credits are not money, are not redeemable for cash, and are not transferable between organisations except as we expressly allow for promotional claims. Unused subscription credits expire at the end of the contracted period unless the Order Form says otherwise. Overage is billed only after agreement or under a documented on-demand rate.

Fees and taxes

Fees are set in the Order Form. Unless stated otherwise, fees are in EUR, exclusive of VAT and similar taxes, and payable as stated in the Order Form. Late amounts may accrue interest at the rate permitted by applicable law.

Customer content and ownership

Customer retains all rights in playbooks, documents, audio, transcripts and other material it uploads or generates in its workspace ("Customer Content"). Customer grants us a limited licence to host, process and display Customer Content solely to provide the service.

We do not use Customer Content to train machine-learning models. Providers that process Customer Content for inference are bound by the same commitment under our contracts with them. See AI Transparency and Subprocessors.

On termination we delete or return Customer Content within 30 days of a written request, subject to legal retention duties, as set out in the DPA.

AI outputs and coaching scores

Outputs of the service, including transcripts, scores, feedback and generated scenarios, are tools for training and coaching. They are not employment, credit, insurance or other legal decisions about a person. Customer is responsible for how its managers use them and for any human review required by law or by Customer's own policies.

AI buyers may interrupt, object or produce imperfect dialogue. Customer should not rely on any single output as the sole basis for a personnel decision.

Maya demo and promotional credits

The public Maya experience on kulissa.com and /maya is a demonstration. Visitors may speak with an AI persona and, if they qualify under the rules shown in the product, receive promotional credits redeemable onto a Customer workspace under the campaign terms shown at the time. Promotional credits may expire, are not cash, and may be revoked in case of abuse. Microphone access is optional and under the visitor's control. Demo use is also subject to the Website Terms below and the Privacy Policy.

Acceptable use

Customer and users must follow the Acceptable Use Policy. Material breach may lead to suspension or termination.

Confidentiality

Each party keeps the other's non-public information confidential and uses it only to perform under these Terms, except for information that is public, independently developed, or required to be disclosed by law (with notice where lawful).

Warranties

We warrant that we will provide the service with reasonable skill and care. Except as expressly stated, the service is provided "as is" and we disclaim implied warranties of merchantability, fitness for a particular purpose and non-infringement to the extent permitted by law.

Liability

To the extent permitted by law, neither party is liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue or data, even if advised of the possibility.

Each party's aggregate liability under these Terms in any twelve-month period is limited to the fees paid or payable by Customer to us for the service in that period. The cap does not apply to a party's fraud, wilful misconduct, payment obligations, or infringement of the other party's intellectual property, or to liability that cannot be limited by law.

Indemnity

Customer will defend and indemnify us against third-party claims arising from Customer Content or from Customer's use of the service in violation of these Terms or applicable law, provided we give prompt notice and reasonable cooperation.

We will defend and indemnify Customer against third-party claims that the unmodified service infringes a patent, copyright or trademark, and will, at our option, procure the right to continue, modify the service, or terminate the affected portion with a pro-rata refund. This obligation does not cover claims arising from Customer Content, combinations with non-Kulissa products, or use after we notify Customer to stop.

Term and termination

These Terms start when Customer first uses the service or signs an Order Form and continue for the term in the Order Form. Either party may terminate for material breach not cured within 30 days of notice. We may terminate immediately for Acceptable Use violations that create legal or security risk. Sections that by nature should survive (ownership, confidentiality, liability, indemnity, governing law) survive termination.

Website terms of use

The public website (kulissa.com, excluding authenticated product workspaces) may be used for lawful information, demo and contact purposes. You may not scrape it aggressively, attempt to break security, or reuse our trademarks except as allowed in the press kit. Content on the site is ours or licensed to us. Competitor names on comparison pages belong to their owners and are used for identification.

Governing law and disputes

Until incorporation completes, these Terms are governed by Swiss law, without regard to conflict-of-law rules, and disputes are submitted to the courts of Zurich, Switzerland, subject to mandatory protections that apply to you. After incorporation, the Order Form may name STEALTH and a different exclusive venue. Nothing prevents either party from seeking interim relief in any court of competent jurisdiction.

Changes

We may update these Terms by posting a new version with a new effective date. Material changes for paying Customers will be notified at least 30 days in advance. Continued use after the effective date constitutes acceptance, except where an Order Form freezes a version.

FAQ

How is Kulissa sold?

As a custom enterprise engagement sized to usage and team needs. Fees and entitlements are set in the Order Form. See Pricing. Maya is a public product rehearsal, not a self-serve catalog.

Do you train models on our calls?

No. See AI Transparency.

Are practice scores employment records?

No. They are coaching tools. Customer decides how managers use them and remains responsible for employment decisions.
