Mast is solving one of the most important problems in lending: Speed. Our mission is to make lending better, smoother and faster for everyone. We do that by empowering mortgage lenders and leveraging technology to enable them to focus on what they do best – lending.

Mast is building cloud-native mortgage technology infrastructure to help lenders process more mortgage applications in less time . We want to help lenders get to a mortgage decision faster and more efficiently, transforming the buying journey for the borrower.

We're backed by top-tier investors and run by a team with deep fintech, product, and enterprise delivery experience. We're already live with regulated enterprise clients, and we've found strong product–market fit in a market that's overdue for change.

Now we're hiring our first commercial leader to help us scale.

Why Join Mast
You'll help transform how lenders operate, not by layering more tech, but by replacing the core. You'll sell software that's genuinely mission-critical, to clients who are crying out for change.
