Fees and Payments
Fees for all services are as stated in the relevant proposal, product description or engagement agreement. All fees are quoted exclusive of VAT (BTW) unless otherwise stated. VAT will be applied at the applicable Dutch rate where required by law.
Exponential Leadership issues invoices by email or via our booking and payment system. For coaching products, events and standard packages, payment is due as specified at the time of booking — typically in advance of the session.
For organisational engagements, invoicing schedules are agreed in the engagement agreement. Payment is due within 14 days of the invoice date unless otherwise agreed in writing.
Exponential Leadership reserves the right to suspend services where payment remains outstanding beyond the agreed period. Late payments may be subject to statutory interest in accordance with Dutch law (Wet handelsrente).
Expenses
Where in-person facilitation or delivery requires travel, accommodation or other reasonable expenses, these are billed at cost unless otherwise agreed in the engagement agreement. Expenses are invoiced separately and on presentation of receipts where requested.
Confidentiality
Confidentiality is a foundational principle of the Exponential Leadership coaching practice — not a contractual formality.
What Exponential keeps confidential
Everything discussed in a coaching, facilitation or advisory session is treated as strictly confidential. We will not disclose the content of any coaching conversation, assessment result or personal disclosure to any third party without your explicit written consent — including, where relevant, to the organisation that commissioned your coaching.
The limited exceptions to this are:
- Where you have explicitly requested or consented to a specific disclosure
- Where we are required to disclose information by law or by a court order
- Where there is a reasonable belief of a serious risk of harm to you or to another person — in which case we will, wherever possible, discuss this with you before taking any action
- For the purposes of professional supervision, where your information will be anonymised
Assessment results
Where an assessment (Hogan or Leadership Circle) is commissioned by an organisation rather than by you personally, the scope of any reporting to the commissioning organisation is agreed with you in advance and confirmed in writing before the assessment is administered. No assessment data is shared beyond the agreed scope.
What you keep confidential
Where you receive confidential information about Exponential Leadership's methodologies, materials, program design or pricing in the course of an engagement, you agree to treat this information as confidential and not to share it with third parties without our written consent.
Intellectual Property
All content on the Exponential Leadership website (including, by extension, our booking sites for coaching and events) — including text, design, program descriptions, frameworks, methodologies and materials — is the intellectual property of Exponential Leadership unless otherwise stated. You may not reproduce, distribute, adapt or use any part of this content for commercial purposes without our prior written consent.
Materials created specifically for you as part of a coaching or development engagement — such as a written development plan, session notes or bespoke program design — are provided for your personal or organisational use. They may not be reproduced commercially or shared with third parties in a way that competes with Exponential Leadership's services.
Third-party tools and frameworks used within Exponential Leadership's services — including the Leadership Circle 360° and Hogan assessments — remain the intellectual property of their respective owners and are used under licence. Nothing in these Terms grants you any rights in those tools beyond what is provided as part of your engagement.
Website Use and Availability
You may use the Exponential Leadership website for its intended purpose — learning about our services, booking sessions and contacting us. You agree not to use the website in any way that is unlawful, harmful or disruptive, including but not limited to:
- Attempting to gain unauthorised access to any part of the website or its underlying systems
- Transmitting any unsolicited commercial communications or malicious code
- Scraping, harvesting or otherwise extracting data from the website for commercial use
- Using the website in a way that infringes the rights of any third party
We reserve the right to suspend or restrict access to the website at any time and without notice where we believe these Terms are being breached.
Links to third-party websites
Our website may contain links to third-party websites. These links are provided for your convenience only. Exponential Leadership has no control over the content or privacy practices of those websites and accepts no responsibility for them. The inclusion of a link does not imply our endorsement of the linked website.
Website availability
We aim to keep the website available and accurate but cannot guarantee uninterrupted access. We reserve the right to modify, suspend or withdraw the website or any part of it at any time without notice.
Limitation of liability
Exponential Leadership's services are designed to support your professional development and organisational effectiveness. The outcomes of coaching, leadership development and facilitation depend on many factors, including your engagement with the process, the context of your organisation and circumstances beyond our control. We cannot guarantee specific outcomes.
To the fullest extent permitted by applicable law, Exponential Leadership's total liability to you arising out of or in connection with our services or these Terms — whether in contract, tort (including negligence), breach of statutory duty or otherwise — is limited to the total fees paid by you for the specific service giving rise to the claim in the 12 months preceding the claim.
Exponential Leadership shall not be liable for any indirect, consequential, special or incidental loss or damage, loss of profit, loss of business, loss of data or loss of reputation, arising out of or in connection with our services, even if we have been advised of the possibility of such loss.
Nothing in these Terms limits or excludes our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any liability that cannot be excluded or limited by Dutch law. Your statutory rights as a consumer are not affected.
Data Protection and Privacy
Exponential Leadership takes the protection of your personal data seriously. Our Privacy Policy sets out in full how we collect, use, store and protect your personal data and your rights in relation to it under the GDPR. The Privacy Policy is available on our website and is incorporated into these Terms by reference.
By using our services, you confirm that you have read and understood our Privacy Policy. If you have any questions about how we handle your personal data, please contact us at info@exponentialleadership.net
Professional Standards and Ethics
Exponential Leadership operates in accordance with the professional ethics codes of the International Coaching Federation (ICF), the European Mentoring and Coaching Council (EMCC) and the Association for Coaching (UK). These codes govern our conduct in coaching relationships, including our obligations with respect to confidentiality, competence, conflict of interest and the welfare of clients.
If you have a concern about the conduct of an Exponential Leadership coaching engagement, we ask that you raise it with us directly in the first instance at info@exponentialleadership.net Where a concern relates to a potential breach of professional ethics, you also have the right to raise it with the relevant professional body.

Your continued use of our website or services after the publication of updated Terms constitutes your acceptance of those updates. If you do not agree with the updated Terms, please contact us to discuss or cease using our services.
Governing Law and Disputes
These Terms are governed by and construed in accordance with the laws of the Netherlands. Any dispute arising out of or in connection with these Terms or our services that cannot be resolved by good-faith discussion between the parties shall be subject to the exclusive jurisdiction of the competent courts of the Netherlands.
Before initiating any formal dispute process, we ask that you contact us directly. Most concerns can be resolved quickly and without the need for formal proceedings.
