Terms of service

These Terms of Service are an agreement between you and Narrowpath Systems, the maker of Cairn (cairncim.com). They apply whenever you create an account, start a trial, or use the product in any way. If you are agreeing on behalf of a firm — and most of our users are — you confirm you have the authority to bind that firm, and "you" then means both you and the firm. If you do not agree to these terms, do not use Cairn. Your use is also covered by our Privacy policy and Security practices, which are part of this agreement by reference.

Cairn is a professional tool for business brokers, M&A advisors, and the firms they work in. You must be at least 18 and using the product for legitimate business purposes — preparing valuations, add-back reviews, quality-of-earnings work, and confidential memoranda for businesses you are engaged to advise on. You are responsible for everything done under your account and for keeping your sign-in credentials secure. Accounts and organizations are managed through our authentication provider; you must give accurate information and keep it current. Don't share a single login across people who should have their own seats, and tell us promptly if you believe an account has been compromised.

Cairn is sold as a monthly subscription in three tiers: Solo ($119/month, 1 seat, 15 active deals), Firm ($289/month, 5 seats included — expandable to 10 with paid seat add-ons, 50 active deals), and Brokerage ($649/month, 10 seats included plus paid additional seats, unlimited active deals). Current prices, seat counts, and deal limits are shown in the product and in your billing settings, and those displayed figures govern if they ever differ from the numbers here.

Every plan starts with a 14-day free trial. Nothing is charged on the day you start. When the trial ends, the plan you selected begins and your payment method is charged for the first period, then on a recurring monthly basis until you cancel. Payments are processed by our payment provider, Stripe; we don't store full card numbers ourselves.

You can change plans or cancel at any time from billing settings. When you change tiers, the difference is prorated. When you cancel, you keep access through the end of the period you've already paid for, and you are not charged again — we don't bill in arrears for a partial month after cancellation. Subscription fees are otherwise non-refundable except where required by law. If a payment fails, we may suspend access until it's resolved; your data is not deleted simply because a payment lapses (see Termination).

Use Cairn for its intended purpose and within the law. Specifically, do not: upload data you don't have the right to process, or financials belonging to a business you are not authorized to advise on; attempt to access another organization's data, probe or bypass the tenant-isolation boundary, or otherwise break the security controls described in our Security practices; reverse-engineer, scrape, or resell the service; upload malware or content designed to disrupt the system; exceed or evade the seat and active-deal limits of your plan through automation or account-sharing; or use Cairn to produce anything fraudulent, misleading, or unlawful. We may suspend access to protect the service, other customers, or the people whose financials are in it.

The most important thing you put into Cairn is other people's money — sellers' real tax returns, P&Ls, bank statements, and the figures we extract from them. We treat that as the whole job, not a footnote.

Your data is yours. We act as a processor of it on your behalf; we do not sell it, and we do not use your customer data to train AI models. Uploaded documents are encrypted at rest, and your organization's records are isolated from every other organization at the database layer — a request from another firm receives "not found," never your data. Within your firm, you control whether deals are visible to all members or kept private to the owner and the people explicitly shared in.

Document content is sent to our extraction provider (Anthropic) over an encrypted connection solely to read and structure your documents for you; the current list of subprocessors is shown live in Settings → Security. CIMs scrub the seller's real business name behind a blind name by default. And your data is yours to remove: deleting a deal removes its documents, extractions, worksheets, and add-back reviews, and the underlying file content is erased from storage. Full detail lives in our Privacy policy and Security practices, which form part of these terms.

Cairn — the software, models, designs, and underlying systems — belongs to Narrowpath Systems, and nothing here transfers ownership of it to you. We grant you a limited, non-exclusive, non-transferable right to use Cairn while your subscription is active and in good standing.

The inputs you upload and the outputs Cairn generates for you — your valuations, worksheets, and memoranda — are yours. You keep all rights in your customer data and in the documents you produce, and you are free to use them however your engagements require. You grant us only the limited license needed to host, process, and display that data so the product can do its work for you. If you send us feedback or suggestions, we may use them to improve Cairn without obligation to you.

This part matters, so it's plain: Cairn is software that helps you do your work faster and trace it to its source. It is not your judgment, and it is not a substitute for it.

Everything Cairn produces is a draft for your review. The product suggests add-backs with the evidence behind them; you confirm every one, and nothing reaches a buyer unconfirmed. Cairn does not provide financial, legal, tax, accounting, valuation, or investment advice, and using it does not create an advisory relationship between you and Narrowpath Systems. Extraction and computation can be wrong — documents are messy and figures can be misread — so you, the broker, are responsible for verifying every number, figure, and statement before you rely on it or send it to a client, buyer, or counterparty. The valuations and memoranda you create are your professional work product, issued under your name and your firm's, and you are solely responsible for their accuracy and for any decisions made on them.

Cairn is provided "as is" and "as available." To the fullest extent the law allows, we disclaim all warranties — express or implied — including merchantability, fitness for a particular purpose, non-infringement, and any warranty that the service will be uninterrupted, error-free, or that any output will be accurate or complete. We work hard on reliability and on the controls described in our Security practices, but we do not warrant that the service will meet every requirement or that defects will always be fixed. You use the outputs at your own professional discretion, having verified them.

To the fullest extent permitted by law, Narrowpath Systems will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any lost profits, lost business, lost goodwill, or lost or inaccurate data — even if we've been advised such damages were possible. This includes any loss arising from a valuation, add-back, or memorandum prepared with Cairn, or from any reliance on the product's output.

Our total liability for any claim relating to Cairn is limited to the amount you actually paid us for the service in the 12 months before the event giving rise to the claim. Some jurisdictions don't allow certain limitations, so parts of this may not apply to you; where that's the case, our liability is limited to the smallest amount the law permits.

You agree to defend, indemnify, and hold harmless Narrowpath Systems and its people from any claims, losses, and reasonable costs (including legal fees) arising out of: your use of Cairn; the data you upload and your right to process it; the valuations, memoranda, or other work product you create and distribute; your breach of these terms or of any law; or any dispute between you and a client, seller, buyer, or other third party. Because the financials you handle belong to others, this includes claims relating to your authority to process that data and to the accuracy of what you issue.

You can stop using Cairn and cancel your subscription at any time from billing settings; access continues through the end of your paid period. We may suspend or terminate your access if you breach these terms, fail to pay, or use the product in a way that threatens the service or other customers — we'll give reasonable notice where we can.

When your subscription ends, your data is not deleted on the spot. We keep it for a reasonable window so you can resume or export, and you can delete a deal and everything in it at any time before or during that window. After the window, or on your request, we remove your data as described in our Privacy policy. The sections that by their nature should survive — confidentiality, intellectual property, disclaimers, limitation of liability, indemnification, and governing law — continue after termination.

These terms are governed by the laws of the State of New York, without regard to its conflict-of-laws rules. You and Narrowpath Systems agree that any dispute arising out of or relating to Cairn or these terms will be resolved in the state or federal courts located in Nassau County, New York, and you consent to their jurisdiction. Before filing anything, please email us — most issues are faster to resolve directly than through a court.

We may update these terms as the product and the law evolve. When we make a material change, we'll update the effective date at the top and, where appropriate, let you know in the product or by email. Changes take effect when posted. If you keep using Cairn after an update, you accept the revised terms; if you don't agree, you can cancel and stop using the service. We won't change the terms retroactively to take away rights you've already earned for a period you've paid for.
