Our History

JP Jenkins was founded in 1991 — from pioneering OFEX to becoming the UK's second PISCES operator in 2025

1991

JP Jenkins Founded

JP Jenkins was founded and established the original OFEX market in the UK to facilitate trading for private and unquoted companies. Notable companies included Weetabix, Arsenal Football Club, Shepherd Neame and NCP. The market was trading over £1bn per annum and supported 500+ companies until the launch of AIM.

1995

OFEX Officially Launched

When the London Stock Exchange launched the Alternative Investment Market (AIM), many smaller companies were unable to meet the new requirements. John Jenkins created OFEX as a separate market, named "Off Exchange" at the LSE's request, providing a cost-effective platform for smaller companies.

2003

Market Evolution

The OFEX market underwent significant changes during a refinancing. The market would eventually be rebranded as ISDX and later transitioned to become what is now AQUIS. The sole broker arm, JP Jenkins, was sold and became part of a corporate finance firm.

2012

New Beginning

A new entity, J P Jenkins Limited, was incorporated to continue the legacy of providing liquidity solutions for privately held businesses in the UK market.

2022

Vision Renewed

A new team came together with the idea to support growth companies in the UK once again. The capital markets were struggling for smaller cap listed companies with 80+ businesses delisting each year since 2007.

2023

Digital Transformation

The JP Jenkins brand was acquired by InfinitX, a technology company, which enhanced the private markets by offering electronic trading across all UK brokers and CREST settlement. At this time, all trading in the private market was done manually via order collection and matching.

March 2024

European First

JP Jenkins became the first private market in Europe to go live with fully automatic trading, allowing for orders to be matched and executed automatically without manual interference or delays.

November 2025

PISCES Authorisation

JP Jenkins received direct authorisation from the FCA to operate a Private Intermittent Securities Capital Exchange System (PISCES) market, becoming the second operator in the United Kingdom. PISCES offers a stamp duty-exempt and regulated environment for secondary liquidity in private company shares.

Today

Dual Trading Environments

JP Jenkins now offers two trading environments: the traditional Matched Bargain Facility and the Private Market which operates under the PISCES framework. We have supported 80+ companies, thousands of shareholders, and traded well over £100m in recent years.

A Legacy of Innovation

From our founding in 1991 to our PISCES authorisation in 2025, JP Jenkins has consistently been at the forefront of innovation in private securities trading. We've evolved from manual trading to fully electronic systems, always with the goal of providing better liquidity solutions for private companies and their shareholders.
