About Us

We specialize in complex digital transformation for financial services

We are passionate about building more agile, dynamic companies through cloud native technologies.

Our specialists thrive in complex, highly regulated environments. They have intimate understanding of the industry, its app ecosystems and security, risk and compliance requirements. We take pride in working alongside you to tackle your toughest challenges.

The work we do reaches far beyond technology, it requires fundamental changes to the operating model, processes and culture of an organization. That’s why people and relationship-building are at the heart of what we do.

Our Leadership Team

Chris Allison

Managing Director New York

Chris Allison

I’ve been in banking IT for around 30 years, mainly with trading-heavy firms like JPMorgan. Over the last decade, I’ve been a big advocate of cloud and I spend most of my time helping clients modernize their tech operating models. I’m happiest skiing with my kids and I believe I may be Citihub’s reigning ski champ (ignore all claims to the contrary).

Matt Gall

PARTNER London

I have 25 years of experience effecting technology and business change in financial services. I’ve worked across the full technology lifecycle for distributed, trading and desktop technologies, and have front-to-back knowledge of capital markets products. When I’m not staring at a computer screen, I’m on my bike, commuting to/from work, or out and about in the hills around SE England.

I run the North American business and global ops, as well as managing key accounts. I’ve been in the industry over 25 years, mainly working with big banks on challenging enterprise-wide programs.

I joined Citihub in 2012 after 8 years at Reuters, cutting my teeth on various eTrading and market data platforms.
