John replaces Paul Aitken, who stepped down as founder and chief executive back in June.
Borro has appointed John Allbrook as executive chairman and chief executive of Borro.
Allbrook was formerly executive chairman of Syscap and has also previously held positions at GE Capital and GoIndustry.
Following a full strategic review Borro has withdrawn from the UK property bridging loan market in order to focus on its core luxury asset finance activities.
Allbrook said: “Borro has carved out a unique space in the financial services market and I am confident about future growth.”
