Keyzy, a web platform that makes rent‑to‑buy a working, scalable model

Keyzy is a UK‑based proptech company focused on making home ownership more accessible. Their rent‑to‑buy model is aimed at people who can afford to rent a home but struggle to qualify for a traditional mortgage or save enough for a deposit. Keyzy helps these customers move into a home while working towards purchasing it. 

The problem we solved 

The underlying problem was the gap between being able to afford a home in terms of monthly payments and being able to actually get a mortgage and buy it. High property prices, deposit requirements and mortgage eligibility rules leave many potential first‑time buyers outside the traditional home‑buying system. Without an alternative model, these people could remain renters for much longer despite being financially capable of owning a home. 

What we built

Keyzy was the original web‑based product and business platform. The main areas we worked on included the customer‑facing website, the main product/application flow, the broker portal and the admin/back‑office interface. We were responsible for the UI and frontend implementation of these parts, working alongside Keyzy’s in‑house developers. The main frontend stack was Next.js, React, TypeScript, Tailwind CSS and Redux. The product evolved over time around the company’s rent‑to‑buy proposition, supporting customers through the process of finding a property, renting it and eventually working towards ownership. The project was continuously developed as the business and its requirements evolved. 

What was harder than expected 

The main challenge was the complexity of the business domain. Buying a home involves many financial, legal and operational factors, so the product requirements could evolve as the business model developed. Understanding the business logic and translating it into a reliable digital experience was more challenging than building a straightforward property or rental platform. 

Outcome & what’s next 

The Keyzy platform continued to evolve and led to the development of Klink, a separate mobile product designed to help potential homeowners prepare financially for buying a property. Keyzy itself is still operating.
