Landbay has exceeded 5,520% growth in revenue between 2016 to 2020.
In addition, the firm has lent £600m within the same timeframe.
According to Landbay, they are now ranked number six on the Deloitte UK Fast 50 and the top ranked mortgage lender.
The ranking is based on revenue growth over the past four years and recognises the 50 fastest-growing technology companies in the UK.
Furthermore, Landbay agreed a funding deal with an asset manager.
As part of the deal, the asset manager intends to fund in excess of £300m per year of Landbay originated mortgages.
Julian Cork, chief operating officer of Landbay, said: “The huge growth we’ve achieved is a testament to how hard our team has worked over the past four years and the excellent intermediaries we work with.
“We set out to become the leading customer services company designing better ways to buy-to-let and this recognition from Deloitte shows we are well on the way to achieving this.
“The key to our success is our scalable, technology enabled and service-focused lending platform.
“We designed process and systems that means we can do things faster and more efficiently and crucially, provide a better experience for intermediaries and their clients.”
