Kreeger (pictured) said it was “always [his] intention” to leave once the bridging lender had successfully integrated with its parent Enra group, which it joined in 2014 when it was bought by Enra-owned master broker Enterprise Finance.
“Now is the right time to complete this transition, and for me to step down and focus on my wider business interests,” he said.
He added: “I would like to thank all the people at West One for their hard work and contribution to the development of the business over the years.”
Kreeger did not say whether he already had another position lined up but it is understood he has business interests in the property sector.
Enra group chief executive Danny Waters said Kreeger had made an “enormous contribution” to West One from the beginning.
The privately-funded company was founded in 2005, as a provider of short-term bridging finance for residential and commercial properties. Since its integration with Enra, West One’s loan book has grown to about £350m.
Waters said: “With West One well-placed for the future, Duncan now feels that the time is right to focus on other interests. On behalf of the business, I’d like to thank him for all the work he’s done, and we wish him well as he looks towards new business opportunities in other sectors.”
