Terms and Conditions

Effective date: 15 September 2026

1. Who we are

AssayBase (assaybase.io) is operated by Yurii Lazebnyi, a sole proprietor (FOP) registered in Kyiv, Ukraine, trading as AssayBase. In these Terms, "we", "us" and "AssayBase" refer to Yurii Lazebnyi.

2. Payments and Merchant of Record

All payments are processed by Paddle.com Market Ltd ("Paddle"). Paddle is the Merchant of Record and authorised reseller of our products. This means you buy the product from Paddle, and the product is licensed to you by us under these Terms.

When you pay, you also agree to Paddle's Buyer Terms: https://www.paddle.com/legal/checkout-buyer-terms. Your receipt and the charge on your card statement will show Paddle.

3. What we sell

We sell custom lists of B2B SaaS companies, delivered as a data file. Each list is built to the criteria you specify. The fields included in each row are described on our website.

4. How ordering works

  1. You send us a request describing the companies you want.
  2. We send you a free sample so you can check the structure, fields and quality.
  3. If you want to proceed, we send you the row count and the price.
  4. You pay through Paddle.
  5. We deliver the full list.

By paying, you confirm that you have reviewed the sample and that the full list is to be built to the same criteria and standard.

5. Pricing

Our pricing is published on our website. At the time of writing it is $0.20 per row with a minimum order of $100. Prices are in US dollars and exclude any sales tax or VAT, which Paddle adds at checkout where applicable.

6. Licence to use the data

When you pay, we grant you a non-exclusive, perpetual licence to use the delivered data for your own business purposes. This includes:

  • research and analysis;
  • sales and marketing outreach;
  • sharing the data within your own organisation;
  • using the data to deliver services to your own clients, such as running outreach campaigns on their behalf, and sharing with a client the companies you contacted or targeted for them.

You may not sell, license or otherwise provide the data as a product. In particular, you may not:

  • sell, resell or license the data file, or any substantial part of it, to anyone;
  • include the data in a list, database or dataset that you sell, license or give to others;
  • publish the data or make it publicly available;
  • remove or alter any notice of our ownership.

If you share data with a client as part of a service, your client is bound by the same restrictions, and you are responsible for their compliance.

If you are buying on behalf of a company, the licence is granted to that company, and you confirm that you have authority to accept these Terms for it.

7. Data accuracy and replacement

We guarantee the accuracy of the rows we deliver at the time of delivery. If a row is unusable, we replace it. The definition of an unusable row, the time limit for claims and the claim process are set out in our Refund Policy.

Apart from that guarantee, the data is provided as is. Company data changes over time, and some fields (such as employee counts or funding totals) are estimates. We do not promise that the data will produce any particular business result.

8. Refunds

Our Refund Policy is at assaybase.io/refund. In short: no refunds after delivery, because the product is data and cannot be returned; full refund if we cannot deliver; replacement of unusable rows.

9. Your responsibilities

You are responsible for how you use the data. In particular, you must comply with all laws that apply to your use, including laws on commercial email, telemarketing and data protection in the countries where you and the companies on the list are located.

You must not use the data for any unlawful purpose or in a way that damages the reputation of AssayBase.

10. Intellectual property

The data compilation, its structure, the selection of fields and the methodology used to build it belong to us. Facts about individual companies are not owned by anyone; what we own is the work of collecting, verifying and organising them. Your licence in section 6 is the only right you receive.

11. Limitation of liability

To the extent permitted by law, our total liability to you under these Terms is limited to the amount you paid for the list in question. We are not liable for indirect losses, lost profits, or losses arising from your use of the data.

Nothing in these Terms limits liability that cannot be limited by law.

12. Changes to these Terms

We may update these Terms from time to time. The version in force is the one published on our website on the date you place an order. Changes do not apply to orders already placed.

13. Governing law

These Terms are governed by the laws of England and Wales. Any dispute that we cannot resolve by discussion will be brought before the courts of England and Wales.
