Team

JUXT has led the research and development of XTDB since the beginning. We are a team unified by strong ideals and our technology-focused mission to improve the software industry, with a huge legacy of open source contributions across the Clojure ecosystem and beyond.

Operations

Jon Pither
CEO
Jon has led projects at Tier-1 Investment Banks, an online newspaper website, a major property portal, and an international public electric bikes scheme. Although he has largely traded Emacs hacking for Zoom meetings in his role as CEO, he is still deeply in touch with XTDB's implementation.
Henry Garner
CTO
Henry is a technologist and author of Clojure for Data Science. He has held CTO roles at RegGenome and Twenty First Group, leading teams applying ML to legal and regulatory data at scale.
Joe Littlejohn
COO
Joe has over 15 years as a principal engineer and leader across music streaming, energy, and developer tooling, with senior roles at Kaluza (OVO), Audiogum, and MixRadio.
Jeremy Taylor
Head of Product
Jeremy became obsessed with databases while working as a solution engineer at IBM. He joined the XTDB team in 2019, prior to the initial public release, and now applies his passion to helping users and customers solve their problems.

Engineering

James Henderson
Head of Engineering
James has spent his career building data-oriented systems in companies large and small, across a variety of domains. Eventually he realised that a lot of the domain complexities he'd faced had 'time' in common, so he came to JUXT to work on a bitemporal database.
Matt Butler
Senior Engineer
During his long career at JUXT Matt has delivered numerous complex projects in multiple sectors, including telecommunications, infosec, and banking. Matt's affinity for hard problems now has him reading database white papers on weekends.
Dan Mason
Engineer
During his time at JUXT, Dan has worked on a number of diverse consulting projects across sectors ranging from Finance to Medtech. He has been a contributor to XTDB since 2019 and is currently working on cloud operations.
