For a full account of his career of twenty-five years in information technology, read the book Entreprenerd: Building a Multi-Million-Dollar Business with Open Source Software.


Wil-Low BV: Wil-Low was founded by Ingeborg Willaert and Bruno Lowagie. With this company, Ingeborg and Bruno provide services as board member, C-level officer, investor, and advisor in different start-ups and scale-ups.

Screensaver BV: In 2021, Ingeborg and Bruno bought the real estate of Sphinx Cinema & Café. The goal is to upgrade the building and to turn it into one of the greatest movie theaters in Flanders.

QLT BV: the main founder of QLT is Jago Lowagie, Bruno's youngest son. Ingeborg and Bruno help their son with a new business model for table tennis events.

iText Group NV: iText Group was originally founded as 1T3XT BVBA (January 2008). The company is based in Ghent (Belgium). The original BVBA (similar to an LLC) was upgraded to an NV (similar to a Corp.) in January 2014. The name was changed from 1T3XT to iText Group. The company became a part of a joint venture with the South-Korean Hancom Group in December 2015. Ownership of the joint-venture changed to private equity players affiliated with Crescendo Equity Partners in 2018.

Bruno also co-founded the following subsidiaries for iText Group:

For those who don't know what iText is about: iText is an open source PDF library available in Java and C#, under either an AGPL or a commercial license. It is a software component (a PDF engine) that can be integrated into a web or other application to create, manipulate and process documents in the PDF format.

Bruno was the original CEO of iText Group until April 2016. He was the CTO from April 2016 until September 2018. He stopped all operational activities at iText on September 23, 2018. He's currently active in Wil-Low BV and Screensaver BV.


When asked for his most important strength as a person, Bruno mentions his ability to reinvent himself.

High school
Bruno majored in Latin and Math, his most favorite subjects in high school. He loved reading books and he loved doing Math. He had his first computer (a TI 99/4A) in 1982, at the age of 12, and by the age of 16, he had developed his own word processor, database system,... in BASIC (on a TRS-80/4P).
Bruno graduated as a civil architectural engineer. He's both an engineer and an architect. He has a degree for designing buildings, not software, yet software development is how he earned a living in the first years of his career.
Pre-entrepreneur career
After college, Bruno did an unpaid internship at a software integrator. He obtained a certificate as "GIS-IT engineer" (GIS being an acronym for Geographical Information Systems). He switched jobs 3 times during the first 2 years of his career, working for different system integrators. In 1998, he became a civil servant at Ghent University. He was the project leader of several IT projects for the student enrollment and administration department. He stayed at Ghent University until 2010.
In 1998, Bruno wrote a first PDF library for Ghent University. While this library worked, it wasn't developer-friendly: a developer had to know the PDF specification inside-out in order to use it. Unhappy with the result, Bruno decided to write a new, better PDF library from scratch. He named this library iText and released a first version as free open source software (LGPL) on February 14, 2000. Soon after the first release, the MPL would be added as an alternative license.
Reputation: Bruno was on Stack Exchange from August 2012 until September 2018, gaining a 72K+ reputation on Stack Overflow and a 4K+ reputation on the Open Source forum:

Because of the many questions posted on the iText mailing-list, Bruno decided to spend a large part of his vacation in 2004 on writing a free online tutorial. This resulted in two book contract offers, one by O'Reilly and one by Manning. He signed with Manning in 2005 and his first book was released in the fall of 2006. Eventually more than 12K copies were sold. A second edition (actually a complete rewrite) was published in 2010. Up until today, more than 10K copies were sold. After this second book, Bruno decided to write free ebooks. The book contract was a catalyst that started the metamorphosis of "Bruno the developer" into "Bruno the Author". In 2019, Bruno started writing fiction stories, resulting in several nominations and awards.

Software IP specialist
The "iText in Action" book turned out to be a great marketing instrument. Suddenly, everyone started using iText. However, this brought about a different type of questions: who owns the IP of iText? iText was offered under the MPL/LGPL and nobody was paying for using iText. Who was responsible for the source code? To answer this question, the Eclipse Foundation suggested that Actuate (a company that is now owned by OpenText) and Ghent University (Bruno's employer at that time) would make a Research Agreement with a complete IP overview as deliverable. This project took the larger part of 2007.
Startup Legal and IP from Bruno Lowagie
At first, working with lawyers wasn't easy for Bruno, but nowadays, maintaining and guarding the IP of the source code has become a second nature. Bruno also gained experience registering trademarks and writing patents. The developer/author reinvented himself as a specialist in software IP and related legal matters.
2008 was an annus horribilis for Bruno and his family. In January, Ingeborg and Bruno founded their first company, but in February, their eldest son (born in 1996) was diagnosed with Cancer. That year, they spent more time in hospital than at a desk.
A Hippopotamus for Christmas from Bruno Lowagie
In 2009, Bruno was faced with a dilemma: either go for the security of a permanent job at the University, or take the leap forward and become a full-time entrepreneur. Or why not try combining both? Bruno switched to working half-time at Ghent University and with the help of Andrew Binstock, a second company was founded: ISC in California. New versions of iText were no longer released under the MPL/LGPL, but under the AGPL. The company started without employees on payroll, but as the business grew, Bruno decided to leave Ghent University. In 2010, he and Ingeborg worked full-time on iText. The first employees on payroll were hired in 2011, when ISB was founded. Today, new employees are being hired every quarter. In 2014, iText opened an office in Singapore, resulting in a first Asian subsidiary in 2015. Reinventing the engineer, developer, and author into being an entrepreneur and a CEO responsible for employees in different continents (having a company that never sleeps) was the most challenging metamorphosis. One of Bruno's favorite quotes featured on Deloitte's Calendar in 2014: Good engineers build great technology; great engineers also create a sustainable business model.

The iText companies were bootstrapped without any loans from the bank, without any funds from a business angel, without any venture capital. Nevertheless, iText was able to grow fast, which resulted in a series of awards such as Deloitte's Fast 50, European and American Business Awards, and so on (see the Awards and nominations page). It hasn't always been that way. These awards are the results of a process of trial and error, learning things the hard way.
Four failures and one hit from Bruno Lowagie
Whatever you do, it's always important to do it in the context of a community. Open source is about sharing, but so is doing business. Nothing is more awarding than sharing your experience with young entrepreneurs who are thinking about starting their own company. That's why Bruno is a speaker at many startup events, such as the Tech Startup Day, Startup Weekend, the Devoxx Startup track,...
Another way to contribute to society is by participating in the creation of new standards. Bruno has been a member of the ISO committees responsible for the PDF standards (ISO-32000, ISO-19005, ISO-14289,...) for many years. This is a two-way process: he uses his experience in the industry to ensure that the standards meet a specific business need (as opposed to being purely academic), and he evangelizes the standards so that they are introduced and used in the business.

Together with his wife, Bruno is a Limited Partner in Smartfin (Capital I and Capital II), a (former) co-investor in a tech company with Volta Ventures and an angel investor in different startups. He also advises companies on how to become investor-ready.
Film Buff and Avid Reader
When asked for his hobbies, Bruno's answer is very predictable: movies and books! For more than 20 years now, Bruno is a Friend of the International Film Festival Ghent, which means that, during the IFFG, you can find him in a movie theater every single day. He's also a regular at the SXSW Film Festival in Austin, Texas. Recently, Bruno also started investing in film. As for books: he reads everything, ficton as well as non-fiction.

When asked for his most important weakness, Bruno admits that he's easily bored. That may sound surprising, knowing that he has been working on PDF for about 20 years, but looking at his track record, you discover that iText has given him the opportunity to reinvent himself many times, which is exactly what makes him tick. He is constantly questioning things: What if everything suddenly changes? What if there's another crisis like the one in 2008? What if competition gets fiercer? Bruno's answer is clear: "I'll simply have to reinvent myself once more; I'll adapt."
