Terms of Service

Last updated: 1 June 2026

1. Acceptance of these terms

These Terms of Service (the “Terms”) form a binding agreement between you, or the organisation you represent (“you” or the “Customer”), and DealBook Ltd, a company registered in England (“DealBook”, “we”, “us” or “our”). They govern your access to and use of the DealBook service made available at dd.sosorry.co.uk (the “Service”).

By creating an account, accessing the Service, or clicking to accept these Terms, you confirm that you have read and agree to be bound by them. If you are entering into these Terms on behalf of an organisation, you warrant that you have authority to bind that organisation, and references to “you” include that organisation. If you do not agree, you must not use the Service.

2. Definitions

• “Customer Documents” means the fund documents, files and other materials you upload to or submit through the Service.
• “Deal Book” means the cited, correctable investment memo produced by the Service from your Customer Documents, including its recommendation.
• “Output” means any Deal Book, extraction, citation, recommendation or other material the Service generates for you.
• “DD” means a single due-diligence run carried out on a set of Customer Documents.
• “Subscription” means a paid plan that grants recurring access to the Service, as described in clause 8.

3. Description of the Service

DealBook is an AI-assisted due-diligence service for private funds. The Service reads the Customer Documents you upload and produces a Deal Book: a structured, cited investment memo that includes a recommendation of Pass, Deep Dive or Invest. Citations are verified against their source passages, and you can correct the Output, which is recorded as an addition without altering the original extraction.

The recommendation and all other Output are advisory and informational only. They are produced to support your own process. The decision whether to invest rests entirely with you and your investment committee. See clause 7 for the full Output disclaimer.

4. Eligibility

The Service is a business-to-business service intended for use by professional and institutional users in the course of their business. It is not intended for, and must not be used by, consumers or anyone under the age of 18. By using the Service you confirm that you are at least 18 years old and are using it for business purposes.

5. Accounts and security

To use the Service you must create an account. Authentication is by email one-time passcode and, optionally, passkeys. You are responsible for keeping your authentication credentials and any device used to access them secure, and for all activity that takes place under your account. You must notify us promptly at dd@sosorry.co.uk if you suspect any unauthorised access to or use of your account. You must provide accurate account information and keep it up to date.

6. Acceptable use

You agree that you will not, and will not permit anyone else to:

• upload, submit or process any Customer Documents or other data unless you have all rights, consents and authority necessary to do so and to have them processed by the Service;
• use the Service for any unlawful purpose, or to upload, store or transmit any content that is illegal, infringing, defamatory, or that you are not entitled to share;
• copy, modify, reverse-engineer, decompile, disassemble or otherwise attempt to derive the source code, models or underlying structure of the Service, except to the extent this restriction is prohibited by law;
• attempt to gain unauthorised access to the Service or its related systems, probe or test its vulnerability, or circumvent any security, rate-limiting or usage controls;
• introduce any virus, malware or other harmful code, or use the Service in a way that could damage, disable, overburden or impair it or interfere with any other user’s use of it;
• resell, sublicense or make the Service available to any third party except as expressly permitted, or use it to build a competing product or service.

We may investigate suspected breaches of this clause and may suspend or terminate access in accordance with clause 13.

7. AI Output — important disclaimer

The Service uses artificial intelligence and large language models to generate Output. By its nature, AI-generated Output may contain errors, omissions or inaccuracies, even where citations have been verified against source passages. We verify that cited passages ground the claims they support, but we do not guarantee the accuracy, completeness or reliability of any Output.

The Output, including any Pass / Deep Dive / Invest recommendation, is provided for information only and is not investment, legal, financial, tax or other professional advice, and does not constitute a personal recommendation or a solicitation to buy, sell or hold any investment. You must independently review and verify all Output before relying on it, and you remain solely responsible for any decision you make. Investment decisions are made by you and your investment committee, not by DealBook.

8. Fees and billing

The Service is offered on the following basis:

• Preview— pay as you go at £20 per individual DD, with no subscription required.
• Solo— £200 per month (or £2,000 per year), including 25 DDs per year.
• Team— coming soon.

Usage beyond a plan’s included allowance is billed at £2 per additional DD. All payments are processed by our payment provider, Stripe. Prices are stated exclusive of VAT and any other applicable taxes, which will be added where required and are your responsibility. Fees for pay-as-you-go DDs are charged at the point of use; subscription fees are charged in advance for the relevant billing period.

9. Subscription term, cancellation and refunds

Monthly Subscriptions are billed month to month and may be cancelled at any time; the cancellation takes effect at the end of the current billing month and you retain access until then. Annual Subscriptions are paid in advance and are non-refundable, but may be paused. Pay-as-you-go Preview DDs are charged at £20 each and, once a DD has been run, are non-refundable.

Except as set out above or as required by law, fees are non-refundable and there are no refunds or credits for partial periods or unused DDs.

10. Customer data and intellectual property

As between you and us, you retain all ownership of, and all intellectual property rights in, your Customer Documents and the Output generated from them. You grant DealBook a limited, non-exclusive licence to host, store, process and otherwise use the Customer Documents solely to provide, maintain and support the Service for you and to generate the Output, and to comply with our legal obligations.

We do not use your Customer Documents to train third-party models. Customer data is held within EU data-residency regions. We retain all rights in the Service itself, including its software, models, design and underlying technology, which are not transferred to you under these Terms.

11. Warranties and disclaimer

We will provide the Service with reasonable skill and care. Except as expressly stated in these Terms, and to the fullest extent permitted by law, the Service and all Output are provided “as is” and “as available”, and we disclaim all other warranties, conditions and representations, whether express or implied, including any implied warranties of merchantability, satisfactory quality, fitness for a particular purpose and non-infringement. We do not warrant that the Service will be uninterrupted or error-free, or that any Output will be accurate or complete.

12. Limitation of liability

Nothing in these Terms limits or excludes either party’s liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be limited or excluded.

Subject to the paragraph above, and to the fullest extent permitted by law:

• we will not be liable for any indirect, special or consequential loss, or for any loss of profits, revenue, business, goodwill, anticipated savings, or loss or corruption of data, however arising, whether in contract, tort (including negligence) or otherwise; and
• our total aggregate liability arising out of or in connection with these Terms and the Service will not exceed the total fees paid by you to us in the twelve (12) months immediately before the event giving rise to the claim.

You acknowledge that the Output is advisory only and that you are responsible for verifying it before relying on it; we are not liable for any loss arising from your reliance on Output that you have not independently verified.

13. Indemnity

You will indemnify and hold us harmless against all losses, damages, liabilities, costs and expenses (including reasonable legal fees) arising out of or in connection with your breach of these Terms, your misuse of the Service, or any claim that your Customer Documents, or our processing of them as permitted under these Terms, infringe the rights of a third party or breach any applicable law.

14. Confidentiality

Each party may receive confidential information of the other in connection with the Service. Each party will keep the other’s confidential information confidential, use it only to perform its obligations or exercise its rights under these Terms, and not disclose it except to those of its personnel and advisers who need to know it and who are bound by equivalent obligations. This clause does not apply to information that is or becomes public other than through a breach, or that a party is required to disclose by law.

15. Suspension and termination

You may stop using the Service and close your account at any time, subject to clause 9. We may suspend or terminate your access to the Service, in whole or in part, if you breach these Terms (including the acceptable use clause), if we are required to do so by law, or if continued provision poses a security or legal risk. Where practicable we will give notice before suspending. On termination, your right to use the Service ends. Any clauses that by their nature should survive termination — including those on fees accrued, intellectual property, disclaimers, limitation of liability, indemnity and confidentiality — will survive.

16. Changes to these terms or the Service

We may update these Terms or the Service from time to time, for example to reflect changes in the law, in our features, or in how the Service operates. Where a change is material, we will give you reasonable notice. Your continued use of the Service after a change takes effect constitutes acceptance of the updated Terms. The “Last updated” date above shows when these Terms were last revised.

17. Governing law and jurisdiction

These Terms, and any dispute or claim arising out of or in connection with them or their subject matter (including non-contractual disputes or claims), are governed by and construed in accordance with the law of England & Wales. The courts of England will have exclusive jurisdiction to settle any such dispute or claim.
