AI-assisted mechanics lien filing and enforcement for unpaid contractors
Lienhound helps contractors, subs and suppliers file and enforce mechanics liens. AI assesses the claim for free, partner law firms send demands and file suits, and filing is a flat fee. It operates in all 50 states.
Lienhound is a web service for construction businesses that have done the work and are still waiting on payment. It focuses on mechanics liens, covering both the filing stage and the later, more neglected stage of enforcement. The central argument on its site is that a recorded lien is only paperwork until someone acts on it, and that deadlines (90 days to enforce in California, six months in Arizona) quietly kill many valid claims. The workflow has four steps. A claimant uploads the contract, invoices and any existing lien, which the site says takes about ten minutes. AI then reviews the claim for deadlines, required paperwork, the property involved and the owner's likely ability to pay, and returns a plain assessment at no charge. If the claim is worth pursuing, an independent law firm sends a formal attorney demand to the relevant parties. When that does not resolve things, a foreclosure suit is filed. The site states that most cases settle at the demand stage. For new liens, Lienhound uses AI to check the details that commonly cause a filing to be thrown out, such as timing and county, and an attorney reviews the document before it is recorded. Filing is a flat fee quoted in advance. Enforcement pricing is shown after the free assessment, and the company says qualifying claims can be paid out of the recovery. Lienhound is explicitly not a law firm: it handles research and document preparation, while licensed firms in each state do the legal work. Service is offered in all 50 states. The intended users are subcontractors, suppliers and equipment rental companies, particularly those stiffed by a general contractor or owner. Compared with hourly construction attorneys, who often decline smaller claims, it positions itself as a lower-cost route by automating review and drafting. It sits between do-it-yourself lien forms and a full retained law firm.
Lien filing is a flat fee quoted before commitment. Enforcement pricing is shown up front after a free assessment, with no hourly billing or open-ended retainers. Payment can come out of the recovery on qualifying claims. No figures are published.
