The specialist packager increased staff numbers by 68% in the past year and launched a new division for development finance loans two months ago.
Brightstar achieved half a billion 15 months ago in July 2014, signalling how the business has expanded since.
Rob Jupp, chief executive of Brightstar said: “Managing £1bn of lending in just four years is a huge achievement and one that everyone in Brightstar should be rightly proud of.
“I would also like to say thank you to all of the brokers and the lenders that we work with and without whom this wouldn’t have been possible.
The loan that took Brightstar over the £1billion mark was a £430,000 bridging loan introduced by Louise Oliver, a broker with Mortgage Advice Bureau, and placed with Precise Mortgages.
Peter Brodnicki, chief executive of Mortgage Advice Bureau, said: “From a standing start Brightstar has made a significant impact on the specialist lending industry.
“By listening to what brokers expect from a specialist distributor they have really started to shake up the standards in the market.
“This first billion will just be the start, I expect Brightstar to continue to go from strength to strength capitalising on the growing market and increasing its market share by delivering an outstanding intermediary service.”
Alan Cleary, managing director at Precise Mortgages, added: “Exceeding £1bn of lending is a significant milestone and I am really pleased it was one of our loans which pushed them over the line.
“Brightstar are a great team and we look forward to helping them pass £2bn of lending in due course.”
