Founded in 2020, our mission is to empower mortgage lenders and leverage technology to enable them to focus on what they do best, lending. An oligopoly of technology suppliers provide a handful of systems that are outdated, get infrequent updates and are painful to customise. Lenders are frustrated and ready for change.

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

We are building self-service products where lenders own all the controls and levers so that they can offer the best service possible. We strongly believe that solving and addressing the hard problems at the roots is the only way to transform an industry.

We are a venture-backed team of finance experts and engineers and have a deep culture of engineering excellence. We believe in people first and pride ourselves on having set the foundations for an excellent internal culture of radical honesty, transparency and innovation. At Mast, we strive hard to create a fast-paced, supportive and fun working environment to enable the team to build the best products in the industry.

Mast hires team members of excellent calibre in every role. While a lot will be asked of you, you will benefit greatly from working in a world-class team, with colleagues who excel. We believe collaboration is the key to success, no matter how many hats we have to wear.

Our Values

We are a principles-first company
No matter the circumstances, our principles are our north star. They guide us to become the best we can be and help us make decisions today to get us one step closer to our mission.


Customers or employees, and people always come first. People build technology to serve people. We are at the service of people, always.


Always do what is right and what is best for everyone.

Candid Feedback

Giving and receiving feedback well is one of the most important traits of learning. At Mast, anyone can voice their opinion, criticise ideas and call us out when we don't do things well, with the aim of assisting.

We are all humans, we are all flawed and none of us knows everything – and that should never be a limiting factor. It's okay to make mistakes, as long as you are happy to ask for help and want to learn. We succeed as a team.


We invest heavily in infrastructure, design and great service. Trust and reputation is a pillar of our identity.

Honesty and transparency
We provide a safe and open environment. We rely on truthful and transparent communication to ensure that the best ideas win.

Pursuit of excellence
Everything we do, we do well or we don’t do at all. Even the things that we don’t see at the surface. Excellence is in the process and in the details. The rest will take care of itself.
