Terms & Conditions

This is a courtesy translation. The legally binding version is the German Terms & Conditions (AGB).

1. Scope

These Terms & Conditions apply to all consulting and development services provided by Thorsten Dunker Investment GmbH, Ohmoor 95C, 22455 Hamburg, Germany (“StackEndeavors”) under the StackEndeavors brand. Services are directed exclusively at entrepreneurs within the meaning of § 14 of the German Civil Code (BGB).

2. Services

StackEndeavors provides services in process consulting, custom software development and AI consulting and implementation. The scope follows the respective individual offer or order confirmation. Unless an explicit work result is agreed, StackEndeavors owes the professional performance of the agreed activity, not a particular commercial outcome.

3. Offer and conclusion of contract

Offers are non-binding unless expressly marked as binding. A contract is concluded by an order confirmation in text form or by commencement of the service. A free initial conversation does not create a contract or any obligation to pay.

4. Client cooperation

The client provides the information, access and contact persons required for the performance of the service in good time and completely. Delays caused by insufficient or late cooperation are not attributable to StackEndeavors and may postpone agreed dates accordingly.

5. Fees and payment

Fees follow the respective offer (fixed price or time and materials at the agreed rates), plus applicable statutory VAT. Unless agreed otherwise, services are invoiced monthly; invoices are due within 14 days of receipt without deduction.

6. Rights to work results

Upon full payment of the agreed fee, StackEndeavors grants the client a non-exclusive, perpetual right to use the work results created specifically for the client (in particular custom software) for the contractually intended purpose. Rights to pre-existing know-how, tools, libraries and reusable components remain with StackEndeavors; the client is granted a non-exclusive right of use to the extent of the contractual purpose. Open-source components are subject to their respective licences.

7. Confidentiality

Both parties treat the other party's confidential information as confidential and use it only to perform the contract. This obligation survives the end of the contract.

8. Liability

StackEndeavors is liable without limitation for damage arising from injury to life, body or health and for damage based on intent or gross negligence. For slightly negligent breach of essential contractual obligations, liability is limited to the foreseeable damage typical for the contract. Any further liability is excluded.

9. Term and termination

Service contracts may be terminated by either party with 14 days' notice to the end of the month in text form, unless agreed otherwise. The right to extraordinary termination for good cause remains unaffected. Services already rendered shall be remunerated in any case.

10. Final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. The exclusive place of jurisdiction is the registered seat of StackEndeavors in Hamburg, where the client is a merchant or legal entity under public law. Should individual provisions be invalid, the validity of the remaining provisions remains unaffected.
