Closinglock
Closinglock is an Austin, Texas fintech and fraud-prevention company whose platform secures the money movement and identity checks inside a residential real estate closing. Title companies, real estate attorneys, agents, underwriters and their buyers and sellers use it to share wire instructions over an authenticated channel instead of email, verify identity and bank-account ownership before funds move, collect and disburse funds through SecurePay digital payments, retrieve and verify mortgage payoff statements, manage and e-sign closing documents, run two-way text messaging with the parties to a file, and evidence FinCEN and ALTA Best Practices obligations. The company announced SOC 2 Type II certification in August 2023 and raised a $34M Series B led by Sageview Capital in January 2025. Closinglock ships integrations into the major title production systems — SoftPro, RamQuest and ResWare — plus a DocuSign e-signature partnership, but those integrations are built bilaterally with each vendor: as of this profile Closinglock publishes no public developer portal, API reference, or machine-readable contract.
Closinglock is profiled on the APIs.io network. Tagged areas include Real Estate, Title Insurance, Fraud Prevention, Payments, and Identity Verification.
Closinglock’s developer surface includes engineering blog, support, signup flow, and 12 more developer resources.
