Terms & Conditions

Last updated 28 October 2026

1. Who these terms are between

Prospex is operated by Sidorenko Consulting, Semion Sidorenko, Chemin du Frêne 7, 1004 Lausanne, Switzerland ("we", "us"). These terms govern your use of the Prospex service at prospex.ch. You accept them by creating an account.

Prospex is offered to businesses and professionals for use in their professional activity. It is not a consumer service, and consumer-protection rules that depend on the customer being a consumer do not apply.

2. Accounts

An account is personal to one named individual. Do not share credentials or let others use your account. Give us a working email address and keep it current — it is how we reach you about the service and about billing. You are responsible for what happens under your account, and you must tell us promptly at hello@prospex.ch if you think it has been compromised.

3. Subscription and price

You can use Prospex free of charge within the free allowance, or subscribe to one of the paid plans below. Each allowance is a number of distinct companies per calendar month.

  • Free: no charge, up to 20 companies per calendar month and 1 built list;
  • Starter: CHF 49 or €49 per month, up to 250 companies per calendar month and 3 built lists;
  • Pro: CHF 99 or €99 per month, up to 1,000 companies per calendar month and 10 built lists;
  • Business: CHF 499 or €499 per month, up to 10,000 companies per calendar month and no limit on built lists;
  • Enterprise: price and allowance agreed with us in writing.

Every paid plan includes every feature of the service, with three exceptions: a custom CRM integration at no additional cost comes with Pro and Business, and tech stack detection and custom signals come with Enterprise. Otherwise the plans differ only in their allowance and in how many built lists you can keep at once. Imported lists do not count. You choose the plan and the billing currency when you subscribe. The subscription is rolling monthly and renews automatically at the end of each paid period until you cancel.

What counts against the allowance. A company counts when you open its full profile, export it, read it through a feed, the API or an AI assistant, or send it to a CRM. It counts once per calendar month, however often and through however many of these you use it again that month. Seeing companies in lists, search results and other tables does not count against the allowance; browsing has its own limit, which protects the service from automated collection. The month resets on the 1st, Swiss time, and an unused allowance does not carry over.

To protect the service, an account can also take only a limited number of new companies in one day; write to us if your work needs more. Past a limit, the remaining companies are held back until it resets.

Changing plan. You can change plan from your account, through the customer portal of our payment provider. An upgrade applies at once: the larger allowance is available straight away and you pay the difference, prorated, for the rest of the current period. A downgrade applies at your next renewal.

You may cancel at any time. Cancellation takes effect at the end of the period you have already paid for; you keep access until then. We do not refund part-months or unused time.

Prices are available in Swiss francs and euros and exclude any taxes that may apply. Payment is processed by Stripe; we never see or store your card details. If a payment fails we may suspend access until it is settled, and may end the subscription if it stays unpaid.

We may change a plan's price or allowance with at least 30 days' notice by email. A change takes effect at your next renewal, and you can cancel before then if you do not want it.

4. Acceptable use

You agree not to:

  • resell, republish, sublicense or otherwise redistribute the data Prospex provides, in whole or in part, whether or not for payment;
  • export the service's contents in bulk, or scrape, crawl or automate access to it beyond the features we provide;
  • share your access with people outside your organisation, or use one account to serve several users;
  • use the data for unlawful direct marketing, or in any way that breaches the rules on unsolicited commercial communication;
  • attempt to circumvent access controls, rate limits or security measures.

Outreach compliance is yours. When you contact a company or an individual you found through Prospex, you act as the controller of that contact. You are responsible for complying with the FADP, the GDPR where it applies, and Swiss unfair-competition law — including giving the required information notice, honouring objections and opt-outs, and respecting the rules on cold contact in each recipient's jurisdiction.

5. What the data covers

Prospex derives its signals from publicly available sources and processes them with automated methods, including large language models. The result is provided "as is". It may be incomplete, delayed, out of date, mistakenly attributed, or simply wrong.

We give no warranty that any signal is accurate, current or fit for a particular purpose. You must not use Prospex as the sole basis for a business decision, and you should verify anything that matters against the original source, which we link wherever we can.

6. Availability

We make reasonable efforts to keep Prospex available, but we offer no service level and no uptime guarantee. The service may be interrupted for maintenance, for upgrades, or by problems at our providers. We may change or discontinue features; if we remove something significant, we will tell subscribers by email.

7. Liability

Our total liability to you, on any basis, is limited to the fees you paid in the twelve months before the event giving rise to the claim. We are not liable for indirect or consequential loss, lost profit, lost business, lost data or missed opportunity.

This limitation does not apply to liability for intent or gross negligence, or to any liability that cannot be excluded under Swiss law (art. 100 of the Swiss Code of Obligations).

8. Intellectual property

The Prospex platform, its software, its interface and the signals it derives remain ours. Your subscription is a non-exclusive, non-transferable right to use the service while it is paid for; it transfers no ownership.

What you put in stays yours: your description of what you sell, your saved searches, your feedback and your notes. You grant us the right to use it to operate and improve the service. We do not disclose your inputs to other customers.

9. Termination

You can cancel at any time, with effect at the end of the paid period. We may suspend or terminate an account that breaches these terms, that does not pay, or that is being used in a way that harms the service or other users; where the breach can be fixed, we will normally ask first. On termination your access ends and section 7, section 8 and section 11 survive.

10. Changes to these terms

We may update these terms. We will give subscribers at least 30 days' notice by email of any material change, and it takes effect at the next renewal. Continuing to use Prospex after that means you accept the new version. If a provision turns out to be invalid, the rest stays in force and the invalid part is replaced by the valid provision closest to its intent.

11. Governing law and jurisdiction

These terms are governed by Swiss law, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. The exclusive place of jurisdiction is Lausanne, Switzerland.
