What We Do

Closinglock is the trusted platform for securing and streamlining real estate transactions. Working with title and escrow companies, we protects what truly matters: their clients, their funds, and their hard-earned reputation. Closinglock brings the real estate payments workflow into one secure space to prevent fraud and digitize the process, allowing buyers to pay their earnest money deposit and down payments digitally in a click, and allows title companies to disburse funds back out to the parties who need to be paid. With over $500 billion in transactions already safeguarded, Closinglock is setting the new standard for secure closings.

Why Work With Us

At Closinglock, we believe security isn't just a feature—it's a responsibility. We're driven by the belief that real estate is personal: understanding that behind every transaction is a person, a family, and a future. If you're looking to work with a purpose-driven team that takes immense pride in protecting people, you'll find your home here.
