Sonde Data · Last updated 15 July 2026
Please read these terms carefully. These Terms of Use (“Terms”) are a contract between you and Syndicate Room Ltd (“SyndicateRoom”, “we”, “us”). They govern your use of Sonde Data (the “Service”), including our website, free plan, paid subscriptions, exports and any other features we make available. By creating an account, subscribing, or using the Service you confirm that you accept these Terms. The Privacy Notice and the Billing, Refunds & Cancellation page form part of these Terms.
Who we are. Sonde Data is a trading name of Syndicate Room Ltd, a company registered in England and Wales (company number 07697935) with its registered office at Wellington House, East Road, Cambridge, Cambridgeshire, CB1 1BH. SyndicateRoom is authorised and regulated by the Financial Conduct Authority (FRN 613021) for its regulated fund-management activities. The Service is a research and information tool and is not a regulated investment service (see section 8).
Who can use the Service. The Service is designed for professional and business use — in particular by angel investors, fund managers, advisers, founders and other professionals carrying out research on UK companies. You must be at least 18 and, if you use the Service on behalf of an organisation, you must have authority to accept these Terms for it. If you use the Service as a consumer, nothing in these Terms affects your statutory rights, and section 13 applies to you.
The Service is a research tool that draws on information from the UK Companies House register and other public sources to help you research UK companies, the people connected with them, and their ownership and funding history. It includes tools that derive estimates and tags from that information — for example an indicative share value, an estimated MOIC/IRR for a portfolio, and tags suggesting sector, funding stage or founder identity.
Parts of the Service are visible without an account (limited public company pages). Full functionality requires a registered account, and some features require a paid subscription, as described on our pricing page and in section 3.
Current plans, prices and inclusions are shown on our pricing page and at checkout. This section sets out how they work; the Billing, Refunds & Cancellation page has a plain-English summary.
Free plan. The free plan includes a fixed lifetime allowance of company lookups (currently three). Opening a company’s page uses one lookup and unlocks full detail for that company; companies you have unlocked remain viewable for as long as you hold an account. The free plan also includes one watchlist with a limited number of companies. We may change what the free plan includes; the pricing page shows the current allowances.
Pro subscription. The Pro subscription is a monthly plan at the price shown at checkout (currently £39 per month, including VAT). It is billed monthly in advance and renews automatically each month until you cancel. Payment is taken by our payment provider, Stripe, through Stripe-hosted checkout and billing pages; we never see or store your full card details.
No free trial. We do not offer a free trial of Pro. Instead, the Free plan lets you look up 3 companies in full detail at no cost and with no card. If you subscribe to Pro, payment is taken immediately and your subscription starts straight away — see Billing & refunds for the 14-day full-refund promise that applies instead.
Cancelling. You can cancel your Pro subscription at any time using the Cancel subscription button on your account page, or by contacting support@sondedata.com. Cancellation takes effect at the end of your current billing period: you keep Pro access until then, and no further payments are taken. We do not refund the remainder of a billing period already paid, except where section 13 (consumers), section 11 (withdrawal of the Service) or the law requires otherwise.
After downgrade. When a subscription ends, your account moves to the free plan and its limits apply. Watchlist entries above the free limit are retained but you cannot add more, and company lookups you have already used count towards the free allowance.
Failed payments. If a renewal payment fails, Stripe will retry it. We may keep your access active during a short retry period, and may suspend or downgrade your account if payment cannot be collected.
Price changes. We may change subscription prices. We will give you at least 30 days’ notice by email or through the Service before a price change takes effect, and it will apply only from your next renewal after the notice period. If you do not accept the new price, you can cancel before it takes effect.
Source data. The Service contains public sector information licensed under the Open Government Licence v3.0. Source: Companies House. We also use a small amount of publicly available company-level information retrieved via third-party services.
Derived and estimated outputs. Several outputs in the Service are estimates we calculate or tags we apply heuristically. These include, but are not limited to:
No warranty of accuracy. Companies House filings can themselves contain errors and our parsing of them may also contain errors. We do not warrant that the information in the Service is accurate, complete or current, and you should verify anything you intend to rely on against the original filings or other authoritative sources.
Removal requests from individuals. Individuals named in the Service may ask to be removed (see our Privacy Notice). When we suppress someone’s record, the underlying picture you see may change.
You may use the Service for legitimate professional research — for example, investment screening, due diligence, market mapping and portfolio monitoring.
You must not:
We may apply rate limits and other technical controls to protect the Service, and may block, suspend or terminate access that we reasonably believe breaches this section. You acknowledge that a breach of this section or section 6 could cause us harm that damages alone would not remedy, and that we may seek injunctive or other equitable relief in addition to any other remedy.
Direct marketing and PECR. If you choose to contact any individual you identify through the Service, you are responsible as an independent controller for ensuring that contact complies with UK GDPR, PECR, and any applicable direct-marketing rules. We do not authorise the use of the Service to build marketing lists.
While you have an account in good standing, we grant you a non-exclusive, non-transferable licence to use the information you access through the Service (“Sonde Data”) as follows:
You may:
You may not:
After your account or subscription ends, you may retain exports made in compliance with these Terms for internal record-keeping and within work product you have already created, but the restrictions above continue to apply to them.
Underlying public data. The underlying Companies House data is public sector information available under the Open Government Licence v3.0, and nothing in these Terms restricts your use of public register data that you obtain directly from Companies House. The restrictions in sections 5 and 6 apply to the Service and to our database, derived outputs, estimates, tags, structure and presentation.
The Service is informational and research-support only. Nothing in the Service is, or is intended to be:
Make your own decisions. You must rely on your own due diligence and, where appropriate, take advice from suitably qualified professionals before making any investment decision. Indicative values, MOIC/IRR estimates and tags are research support only, not statements of value or recommendations.
SyndicateRoom’s regulated activities. SyndicateRoom is FCA-authorised for its fund-management activities, which are conducted separately under SyndicateRoom’s regulated terms and disclosures. Your use of the Service does not create any client relationship with SyndicateRoom in respect of those regulated activities.
No Ombudsman or FSCS cover. Because the Service is not a regulated investment service, the Financial Ombudsman Service and the Financial Services Compensation Scheme (FSCS) do not apply to the Service. This does not affect any rights you may have in relation to SyndicateRoom’s separate regulated activities, or your statutory rights as a consumer (see section 13).
Our handling of personal data is described in the Service’s Privacy Notice. By using the Service you confirm you have read it. Where you use information from the Service to process personal data for your own purposes, you do so as an independent controller and are responsible for your own compliance with UK GDPR and PECR.
Nothing in these Terms limits liability that cannot be limited under English law (including liability for death or personal injury caused by negligence, or for fraud), and nothing in these Terms affects a consumer’s statutory rights or remedies.
Subject to that:
If you are a consumer. We are responsible for loss or damage you suffer that is a foreseeable result of our failing to provide the Service with reasonable care and skill, or of our breaking this contract. We are not responsible for loss that was not foreseeable, for loss caused by relying on outputs contrary to section 4’s guidance to verify against original filings, or for business losses. The cap in this section does not apply to you. Nothing in this paragraph limits your rights under the Consumer Rights Act 2015.
Professional users. Because the Service is intended for professional use and its outputs are estimates and heuristics, you accept that exercising your own judgement and verification is part of using it properly.
This section applies if you use the Service as a consumer — that is, wholly or mainly outside your trade, business, craft or profession.
If you use the Service in the course of a business and breach section 5 or 6, you agree to compensate us for losses, damages and costs (including reasonable legal costs) that we reasonably incur as a result of the breach. This section does not apply to consumers.
We may update these Terms from time to time. If a change is material, we will give you at least 30 days’ notice by email or through the Service before it takes effect, and if you do not accept it you can cancel your subscription or close your account before the change applies. Minor changes — for example to reflect new features, legal requirements or security needs — may take effect immediately. Continuing to use the Service after a change takes effect means you accept the updated Terms.
