From the very start of the process, to the very end, we help deliver what your business need to grow.

Dr. Benjamin Senior & Team

The founder of Sefol - Dr. Senior - has a First Class Bachelors degree in Computer Science, Masters of Research in Informatics, and PhD in Software Engineering from the British University of Manchester. After half a dozen startups, consultancy for companies ranging in size from single traders to eBay and Daimler, across Europe and North America, and almost twenty years in the trenches of software and business - he still hasn't lost his passion for delivering excellent results. Here are a few recommendations :

Andreas Lüdeke – CTO, TestObject

Great quality and the feature scope we had in mind.

Peter Kiess – Managing Director, GIS GmbH

Dr Senior built an extraordinarily good understanding of our complex software requirements, in a very short space of time. He doesn’t just talk, he proved his competence by delivering solutions very quickly. As well as his academic and practical qualities, he also possesses a very high degree of social and emotional competence, important characteristics for successful Change Management.

Richard Manuel – Managing Director, Perbit GmbH

Sefol’s advice on content and presentation was first class. Everything delivered as promised and on time. These people are a pleasure to work with.

Koen Stevens, BuboBox CEO

…a very strong problem-solver with an analytical mind, who can also put theory into practice. We hired him for Red5 consultancy, but he has a very broad knowledge field. Highly recommended!

Various Daimler Managers, from E4 to E2

“Was kaum jemand für möglich gehalten hat”, “das ist/war eine außergewöhnliche Leistung …. kritisches Thema, extrem enge Zeitleiste”, “ich muss sagen, dass ich echt beeindruckt bin was Sie und Ihr Team in der kurzen Zeit geschafft haben. Echt klasse. Super Arbeit ….. DANKE !!!”

Dr Mark van Harmellen – Managing Director, Hedtek Ltd.

Sefol produced great results on time and in budget. Their regular client communication, responsiveness to changing needs, and technical excellence make them a pleasure to work with. As a result of our experiences with Sefol we have now placed repeat business with them.

Mate Jovic – Managing Director, Matoma GmbH

Dr Senior was asked to speed up the User Interface development process on a difficult project. He inspired the team to implement both the technology and methodology he recommended, resulting in improved speed, quality, and team satisfaction.

Dr. med. Gunther Essinger – Medizinischer Direktor

“PsychePilot” [a Sefol project] ist praxisnah, anwendbar, innovativ und erweitert die bisherigen Möglichkeiten in der Therapie, Rahmen integrierter Versorgungsprojekte. Ein besonderer, auch gesundheitspolitisch wichtiger Aspekt ist die bessere Steuerbarkeit der insgesamt knappen Resourcen im Gesundheitssystem.

Gerhard Weindler, Steinbeis Institut

Kompliment, Kompliment! Hervorragende Arbeit.

The Laviu Team

Ben did a great job constantly motivating us with fun and inspiration. His new perspectives helped us to think out of the box and improve our ideas.

Hugo Honda - Lead Dev

Ben was the inspiring guy who understood not only what I was trying to say, but transformed it into concrete ideas that built our product. A guide for our confusing brainstorm!

Tobias Franke - Intern

I feel like I learnt more in the three months I spent with Sefol, as I did in the last three years of University!
