Thompson Taraz is pleased to have supported Longstock Capital on the first close of the new £100m Longstock Office Investment fund. Founded and led by Tristan de Souza and Hugo Denée, Longstock’s UK deals track record has enabled them to successfully reach first close with the backing of investors from both the UK and US.

Reaching this milestone from the commencement of conversations just months ago, particularly in a challenging fundraising landscape, is testament to the confidence investors have in Longstock’s strategy and capabilities. Thompson Taraz shares this confidence.

“I’m delighted to work alongside Tristan and Hugo, and to have collaborated to get the Longstock Capital fund to this first close. They are a further addition to our roster of first-time and emerging managers, and I look forward to our continued collaboration and development of a long and successful partnership.”

Philip Shearer, Chief Commercial Officer at Thompson Taraz.


“We've enjoyed and benefited greatly from Thompson Taraz’s collaboration to date. The team’s entrepreneurial spirit, agility and pragmatism have been extraordinary. We have been particularly impressed by the efforts TT have made to truly understand our business and calibrate the service offering accordingly. We look forward to a long and successful partnership with the TT team and cannot recommend them highly enough.”

Tristan de Souza, Founder at Longstock Capital.
