Why Jonas Hero Why-Jonas-Hero-400-800

What does Jonas do?

We seek, buy and invest in the most promising software companies in a wide range of verticals throughout the UK and Europe.

However, our process involves so much more than simply acquiring. We coach and evaluate new resources to develop, expand and grow – both as businesses and as people – enabling you to think bigger, evolve faster and continue to be or become industry leaders, while supporting your personal wellbeing and success.

We are truly committed, acquiring companies and welcoming them into our group to nurture them forever, not to rinse and sell-on in a few years. We invest in and build on what was already great, allowing a brand and its employees to truly shine and fulfil their potential.

Our philosophy

Our vision:

To be the desired forever home of niche vertical market software brands and their people.

Our mission:

To grow our unique family of software brands and the people behind them. Delivering value for customers, employees and investors, while having a positive impact on communities.

Take advantage of our backing, leverage and resources

Jonas UK & Europe is an operating group of one of the largest software companies in the world, Constellation Software Inc. (CSI). This means we can provide not only financial backing and security but a huge depth of knowledge and a vital global peer-to-peer support network as well.

Constellation is home to six operating groups, serving over 120,000 customers across 100+ vertical markets in over 100 countries. This gives us the funding, frameworks, credibility and expertise to keep our core promise: we’ll bring your company into Jonas to keep and support it forever. We acquire businesses, we do not sell them.

Where we’ve come from

Our trajectory since 2010 will give a good indicator of where we’re going. From initial acquisitions in the club and construction markets in North America to our current holdings in a huge range of software companies worldwide, our network and growth continues.

The focus is on your autonomy and growth

We buy into a company’s brilliance. Your market knowledge, your software, your people and your vision – and we love what you’ve built so far. That’s why we’ll empower you with the autonomy to keep doing your thing, only with the benefit of the Jonas’ decades-long experience of running software businesses and our People Development Programme.

Your company will still retain its heritage and control over its branding, identity and operations, albeit with the overlay and benefit of a world renowned owner as your financial partner. We’ll share your aspiration to build on it further, together.

Giving back to the world

It’s important that the time and energy going into our business every day contributes towards more than simply driving profits. We want to help ‘pay it forward’ to worthwhile causes that are close to our hearts.

Through the Jonas Software Foundation, we work with a number of charities that align with our vision, actively focusing on sustainability within our organisation and supporting up-and-coming talent with our apprenticeship programme.
