Team | untied

The untied team have form – most of us have launched businesses together before. We love working together and we’re passionate about what we do. We’re made up of chartered accountants, tax professionals and Robotic Process Automation specialists with a track record in getting things done and finding novel solutions to thorny problems.

Kevin Sefton

Kevin Sefton

CEO & Co-Founder

A serial entrepreneur with a background as a chartered tax advisor, Kevin has launched several tech businesses, including an internet payments business way before internet payments were much of a thing. He has a knack for finding imaginative solutions to tricky problems. Fellow of the Institute of Chartered Accountants. Loves white boards, taking strolls, baking bread and riding his bike.

Marcus Tettmar

Marcus Tettmar

CTO & Co-Founder

When it comes to tech there’s not much Marcus can’t turn his hand to. He’s not an accountant, but probably knows more about personal taxes than he’d care to admit. He co-founded a dot com business with Kevin back in the early 2000s and launched his own RPA technology with clients including NASA, Microsoft and BBC. These days some call it Full Stack Development. Marcus is more modest, and calls it Slave of All, Master of None.

Richard Mann

Richard Mann

Chair

Cool, calm and collected, nothing ever fazes Richard. A serial entrepreneur, mentor and investor, Richard started his journey back in the 90s doing blue chip mergers and acquisitions and has gone on to launch and grow a number of successful tech companies, including one with Kevin, Marcus and Paul. Fellow of the Institute of Chartered Accountants and a true polymath, he’s just as comfortable coding a neural net in Python as he is negotiating his next business exit!

Paul Basham

Paul Basham

COO

Another Fellow of the Institute of Chartered Accountants, Paul started his career as a blue chip tax accountant and went on to co-found an internet payments business with other members of the team. Since then he’s gone on to several Financial Director roles with experience of HR, Ops and SaaS before joining the team again at untied. He tells it like it is, is a bit of a wine buff and, ignoring everyone’s advice, is currently in the process of setting up a salt water tropical aquarium.

Taxberry

Taxberry

Mascot

Round, red, cheerful and brings joy to taxpayers throughout the UK, Taxberry is here to help you and dedicated to the job. We love Taxberry!

Mickaelle Schwarzberg

Mickaelle Schwarzberg

Projects & Partnerships

Experienced digital projects manager and digital growth specialist, formerly with KPMG. Has worked in France, Germany and the UK. Brings a certain je ne sais quoi – and organisation – to the untied team. Outside of work enjoys performing in a French drama group. Unfortunately – or fortunately – for the rest of us – theatres don’t do subtitles.

Chris Anderson

Chris Anderson

CPO

Oversees everything product related. So at untied that’s basically everything. Could be the first person who’s ever been able to make Kevin and Marcus do regular early morning meetings. Like Marcus he started his career writing COBOL (Google it kids). Unlike Marcus that was as recently as 2005. Yeh we were amazed it still existed too. Loves motorbikes.

Andrea Caporale

Andrea Caporale

Design Advisor

A highly accomplished and experienced user experience designer who is passionate about finding ways to simplify people’s lives. Currently a senior designer at Microsoft, previously an Associate Lecturer at University of the Arts London where he ran user experience design courses. Enjoys traveling almost as much as his dog George enjoys eating cushions.

Richard Haddlesey

Richard Haddlesey

Full Stack Developer

Richie (we already have a Richard in the team) writes code and helps Marcus deliver the product. Richie’s software development career is a little unusual as along the way he has done electrical engineering, studied medieval architecture and digital archaeology and taught IT in schools and training centres. Why not? At weekends he DJs.
