4D Capital Partners

What 4D Capital Partners does

4D Capital Partners LLP is a London- and Wetherby-based special situations private equity firm founded in February 2023 by Alex Silk. The firm acquires UK-headquartered distressed and underperforming companies with minimum revenues of £20m, deploying initial equity investments of £1-5m (up to £10m) for majority positions sourced from owner-managers, large corporates and other investors. Its deal scope spans working-capital-constrained growth companies, capital-structure resets, under-invested incumbents and corporate carve-outs.

Unlike traditional mid-market PE, 4D is backed by a single Ultra High Net Worth family office rather than a closed-end fund and does not charge arrangement, monitoring or other GP-level fees. The firm instead bills portfolio companies for the time of its in-house financial and operational experts, payable once the investee generates sufficient cashflow. The four-person partner team (Alex Silk, Daniel Newett, Daniel Hannappel, Dominic Wong) combines investment-banking, restructuring and operational backgrounds from Mutares, Deloitte, Porsche Consulting, Deutsche Bank and Alantra, and is deployed directly into portfolio companies rather than outsourced.

The portfolio comprises four wholly-owned UK businesses: Britten-Norman (aircraft manufacturer, acquired March 2024 out of administration, with hydrogen-variant plans and a January 2026 follow-on round led by 4D), Hepworth Clay (the UK's only vitrified clay pipe manufacturer, carved out from Wavin/Orbia in June 2025), JJ Ormerod plc (kitchen, bedroom and bathroom furniture manufacturer, 1868-founded, ~300 staff, 1.2m sq ft East Lancashire facility, acquired August 2025), and York Handmade Brick (premium handmade bricks for heritage and luxury construction, acquired December 2025). The latter three are being integrated into a building-products group, with the firm publicly reporting £1.9m of annualised EBITDA improvement at Hepworth Clay within the first six months of ownership.
