LienDeadline Information

LienDeadline is an independent software company founded in 2025 by Peter Hallander and Mathias Åsberg. We build deadline calculation and document tooling for construction credit, finance and legal teams across the United States. The product covers mechanics lien and preliminary notice deadlines for all 50 states plus the District of Columbia, and is available both as a web application and as a REST API. The underlying state rule set is reviewed on a quarterly cycle so customers are not calculating against stale statutes. We are a small engineering team, not a law firm.
