Terms of Service

Last updated 11 August 2026 · Effective 11 August 2026

These Terms are the agreement between you and Osseus for the Osseus development platform and the Osseus marketplace. Please read them carefully. By creating an account or using either service, you accept them.

1.Who we are

The Osseus platform and the Osseus marketplace are operated by the company trading as Osseus (“Osseus”, “we”, “us” or “our”). You can reach us at hello@osseus.ai.

Platform” means the Osseus development platform at app.osseus.ai that connects a robotics team’s design, engineering and supplier records into one permissioned memory and provides review, change-impact and assistant features. “Marketplace” means the Osseus marketplace at marketplace.osseus.ai where users list, rent and sell robotics hardware. “Services” means both, together with this website. “Workspace” means the account tenancy that holds your organisation’s data. “You” means the person or organisation using the Services.

2.Acceptance & eligibility

By creating an account, accessing a workspace, or listing, buying or renting on the Marketplace, you agree to these Terms. If you use the Services on behalf of an organisation, you confirm you are authorised to bind that organisation, and “you” means that organisation.

The Services are intended for businesses and professional users and are not directed to children. You must be at least 18 years old and able to form a binding contract to use them.

3.Accounts & access

Access to the Platform is granted to identities that an administrator has added to a workspace; signing in never creates access on its own. You may create a Marketplace-only account through self-serve signup. A Marketplace-only account can use the Marketplace but not the engineering Platform; a full workspace account can use both with a single sign-in.

You are responsible for keeping your credentials secure and for activity under your account. Within a workspace, a listing you create on the Marketplace is managed by you; colleagues in the same workspace cannot edit, publish or archive it unless they are a workspace administrator. Tell us promptly at hello@osseus.ai if you suspect unauthorised use.

4.The Osseus platform

The Platform lets you connect engineering systems — for example CAD and PLM, schematics and ECAD, bills of materials, source repositories, issue trackers, chat and documents — so that changes, decisions and supplier feedback stay linked across a design. When you connect a third-party tool you authorise us to access it on your behalf, and only within the scope you grant; you can disconnect it at any time.

We grant you a non-exclusive, non-transferable right to use the Platform for your internal business purposes during your subscription. You must not misuse the Services, including by attempting to break isolation between workspaces, probing or bypassing security controls, scraping at scale, reselling access, reverse-engineering the software, or using the Services to build a competing product.

We may improve, change or discontinue features. We will not make a change that materially reduces the core functionality of a paid plan during a term you have already paid for without offering a pro-rata refund of the unused portion.

5.AI-assisted features

The Platform includes AI-assisted features that summarise, review, answer questions about and suggest actions across your connected records, with citations to their sources. These outputs are assistive, not authoritative. They can be incomplete or wrong, and they are not engineering, legal, safety or professional advice.

You remain responsible for your engineering decisions. A person must review and approve any action Osseus proposes before it takes effect — nothing is written back to a connected tool without that approval. Verify AI output against the cited sources before relying on it.

Simulations and tests run locally on infrastructure you control. Osseus can be deployed on-premises or in your private cloud, keeping designs, requirements and test data within your controlled environment. Where external AI APIs are used, we use Zero Data Retention configurations so submitted data is not stored by the provider or used for model training.

We use third-party model providers to deliver these features. We do not permit your confidential workspace content to be used to train third-party foundation models; it is processed only to produce your result. See our Privacy Policy for details.

6.Subscriptions & billing

Paid Platform plans are billed through our payment processor, Stripe. Plan names, prices, seat counts and billing periods are shown at checkout and in your billing settings, and those figures govern. Unless stated otherwise, subscriptions renew automatically at the end of each billing period.

  • Renewal & cancellation. You may cancel from your billing settings, effective at the end of the current period. Access continues until then.
  • Fees & taxes. Fees are exclusive of taxes; you are responsible for any applicable sales tax, VAT or similar, unless we are required to collect it.
  • Non-payment. If a charge fails and is not cured, we may suspend or downgrade the workspace.
  • Refunds. Except where required by law or expressly stated, fees are non-refundable once a period has begun.

Marketplace subscription or listing fees, if any, are described on the Marketplace and are separate from Platform subscriptions.

7.The Osseus marketplace

The Marketplace is a venue where users list robotics hardware for rent or sale and transact with one another. Osseus is not a party to any transaction between a buyer and a seller. We do not own, inspect, take possession of, or warrant any item listed, and we are not the seller, buyer, manufacturer, importer or lessor. The contract for any rental or sale is between the users involved.

If you sell or rent (seller)

  • You must have the legal right to sell or rent the item and to transfer or grant use of it.
  • Your listing must be accurate and complete: title, description, condition, specifications, price, quantity, lead time, location and any rental terms.
  • You are responsible for the item’s safety, legality and fitness, for honouring the terms you publish, and for any tax, export, customs, warranty or regulatory obligation attaching to the item or the transaction.
  • For rentals, you set the rental window, deposit and any late-return terms, and you must not double-commit dates the calendar shows as taken.

If you buy or rent (buyer)

  • You are responsible for assessing whether an item is suitable, safe and lawful for your intended use before ordering.
  • You must pay agreed amounts, return rented items on time and in the agreed condition, and comply with any export or end-use restriction.

Keep marketplace communication and transactions on-platform. Attempting to move a deal off-platform to avoid fees, protections or the record, or sharing off-platform contact details to do so, is not permitted and such messages may be blocked.

8.Marketplace payments & deposits

Marketplace payments are processed by Stripe. By transacting you also agree to Stripe’s applicable terms. We may facilitate the flow of funds, apply a platform fee disclosed at checkout, hold a rental deposit, and release, capture or refund amounts according to the state of an order — but we do so as an operator of the venue and the payment integration, not as a principal to the sale.

  • Deposits. A refundable deposit may be authorised or held for a rental and returned when the item is returned in the agreed condition, less any agreed deductions such as late-return fees or damage.
  • Disputes. Buyers and sellers are responsible for resolving disputes about items, condition, delivery or returns between themselves. We may, at our discretion, provide transaction records or mediate, but we are not obliged to and are not the arbiter of a dispute. Condition evidence uploaded to a listing or order helps resolve disputes.
  • Chargebacks & reversals are governed by Stripe and the relevant card scheme.

9.Prohibited items & conduct

You must not list, sell, rent, buy or transmit through the Services:

  • weapons, munitions, or components designed for them, and any item whose primary purpose is to cause harm;
  • goods or technical data whose export, re-export or transfer is restricted or requires a licence you do not hold, or that would breach sanctions or end-use controls;
  • counterfeit, stolen, recalled, or unsafe goods, or goods you have no right to sell;
  • hazardous materials handled contrary to applicable law;
  • content that is unlawful, infringing, malicious, or that violates another person’s rights.

You must not misrepresent an item or your identity, manipulate reviews, or use the Services to defraud. We may remove a listing, cancel an order, or suspend an account that we reasonably believe breaches this section.

10.Your content & licences

You keep all rights in the data, files, listings and other material you or your connected tools provide (“Your Content”). You grant us a worldwide, non-exclusive licence to host, process, transmit and display Your Content solely to operate and improve the Services for you — for example to index it into your workspace memory, generate cited answers for you, stream a listing photo, or deliver a message to a counterparty.

For Marketplace content you publish (such as a listing and its photos), you grant us and other users the licence needed to display and transact against it while it is published. If you give us feedback about the Services, you allow us to use it without obligation to you.

11.Osseus intellectual property

The Services, including the software, models, interfaces, and the Osseus name and logo, are owned by Osseus and its licensors and are protected by intellectual-property law. These Terms grant you a right to use the Services, not any ownership of them. All rights not expressly granted are reserved.

12.Third-party services

The Services rely on and integrate with third parties — including Stripe (payments), our identity provider (sign-in), AI model providers, cloud hosting, and any engineering tools you connect. Your use of a connected tool remains governed by that tool’s own terms, and we are not responsible for third-party services or for how a counterparty or connected provider behaves.

13.Data protection

Our Privacy Policy explains what personal data we process and why, and forms part of these Terms. Where we process personal data on behalf of a business customer as a processor, a data processing agreement compliant with applicable data-protection law (including the UK GDPR / EU GDPR Article 28 where relevant) is available on request at hello@osseus.ai.

14.Disclaimers

The Services are provided “as is” and “as available”. To the fullest extent permitted by law, we disclaim all warranties, express or implied, including fitness for a particular purpose, merchantability, non-infringement, and any warranty about the accuracy, completeness or reliability of AI output or of any listing, item, user or transaction on the Marketplace. We do not warrant that the Services will be uninterrupted or error-free.

15.Limitation of liability

To the fullest extent permitted by law, neither party is liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill. Our total aggregate liability arising out of or relating to the Services is limited to the greater of (a) the fees you paid us for the Services in the twelve months before the event giving rise to the claim, or (b) US$100.

Nothing in these Terms excludes liability that cannot be excluded by law, such as liability for death or personal injury caused by negligence, or for fraud. Because Osseus is not a party to Marketplace transactions, we are not liable for the items, acts or omissions of buyers or sellers.

16.Indemnity

You will indemnify and hold Osseus harmless from claims, losses and reasonable expenses arising from your breach of these Terms, Your Content, your items or transactions on the Marketplace, or your misuse of the Services, except to the extent caused by us.

17.Suspension & termination

You may stop using the Services at any time and cancel a subscription as described above. We may suspend or terminate access if you breach these Terms, if required by law, or to protect the Services or other users. On termination your right to use the Services ends. We retain and delete data as described in the Privacy Policy; some records are retained where we have a legal basis to do so.

18.Changes to these Terms

We may update these Terms. If a change is material we will give reasonable notice, for example by email or in-product. Changes take effect on the “last updated” date shown above, and continuing to use the Services after that date means you accept them.

19.Governing law & disputes

These Terms are governed by the laws of the State of California, USA, without regard to its conflict-of-laws rules, and the parties submit to the exclusive jurisdiction of the state and federal courts located in California. If you deal with us as a consumer, this does not deprive you of any protection given by mandatory law of your place of residence.

20.General

These Terms, with the Privacy Policy and any order or plan you accept, are the entire agreement between us about the Services. If any provision is held unenforceable, the rest stays in force. Our not enforcing a right is not a waiver of it. You may not assign these Terms without our consent; we may assign them to an affiliate or in connection with a merger or sale. We are not liable for delay or failure caused by events beyond our reasonable control.
