Catalyst Property Finance has been acquired by The FHL Group, which is a sister company of Foundation Home Loans.
The company will keep its brand and continue to operate separately.
Catalyst said the deal would give it access to a wider funding pool and allow for more product options and better pricing.
Brokers will see new products and more support for their property developer and investor clients.
Chris Fairfax (pictured), CEO of Catalyst Property Finance, said: “Establishing Catalyst as a leading name in specialist finance has been an enormous privilege, and we’re thrilled to be entering the next chapter of this journey with the backing of the group.
“I work alongside a hugely talented and dedicated team who have been instrumental in our success to date.
“Together, from a standing start in 2017 with very limited equity and resources, fueled by a passion to be pioneering and to challenge convention, we have lent over £600m with exceptional book performance and profitability every year.”
Fairfax added: “We share our vision for the future with Pete and the wider group; we speak the same language and share common goals.
“The timing was perfect, they were looking to diversify, and we needed funding to enable us to deliver upon our ambitious plans.
“My team and I are excited for the coming months and years; brokers can expect Catalyst to launch creative finance products that really meet their clients’ needs, we will continue to invest in and streamline our lending processes, and we’ll always ensure they have the dedicated support from our brilliant team they have grown to expect.
“With the groups’ backing, we’re ready to be a Catalyst for positive change in the specialist market.”
Pete Ball, CEO of Foundation Home Loans, said: “I’m really pleased to welcome Chris and the whole Catalyst team to the group.
“This is a great fit, as it allows us to support the property ambitions of a broader range of borrowers.
“Catalyst is already a standout name in bridging and specialist finance, and this move allows us to expand into new areas where they’ve already built a highly impressive reputation.”
Ball added: “There will be no operational or resource changes as a result of the acquisition.
“Our role is to support Catalyst with an enhanced, diversified funding line, and to help it achieve the long term ambitions and growth plans that we, and they, have for the future.”
