Startline Motor Finance saw a 35% rise in the number of dealer groups which include it in their lender panel since the beginning of the year.
The company said that it is currently in the lender panel of more than 50 dealer groups.
Chief executive officer at Startline Motor Finance Paul Burgess said the rise was prompted by the company’s approach, as it often looks closely at "applicants others might reject."
Burgess explained: "As a service-led lender, we tend to be more agile and dynamic than most, with customer service and underwriting teams that have a higher degree of independence than at most large finance businesses.
"This means that we are set up to look closely at applications that others may have had automatically rejected by their online systems."
As part of the increase in business being assessed, Startline said it is also planning to expand its staffing levels over the coming months.
"We need to recruit staff right across the business including senior sales roles in the north of England and elsewhere," Burgess added.
