Case Study: Next Door Lending achieves rapid scale and frictionless onboarding with Supabase

How Next Door Lending leveraged Supabase to become a top 10 mortgage broker

Next Door Lending, a national mortgage broker operating in 25 states, needed a secure, scalable way to manage sensitive lending data while keeping borrower onboarding fast and frictionless. As the company grew, it also wanted an infrastructure foundation that could support future AI and predictive matching products. To meet these needs, Next Door Lending turned to Supabase for database, authentication, and storage capabilities.

With Supabase, Next Door Lending built a centralized backend for multiple branch websites, using Supabase auth, row-level security, and APIs to manage borrower signups, loan data, and custom onboarding flows. The platform helped the team move faster, launch new features, and support a dynamic website with a reported 0.5-second load time. As a result, Next Door Lending scaled into one of the nation’s top 10 mortgage brokers and expanded its business into “NDL as a service” offerings through Neighbourhood Tech, all on Supabase.
