Legacy software brings more trouble than benefits

An outdated system bogged down by years of ad-hoc changes and quick fixes. Result: increased maintenance costs and inefficiency. Sounds familiar? Then modernizing your legacy application is crucial to reduce technical debt and restore profitability.

It's time-consuming

23% of developers' time is wasted on working on technical debt

Because of legacy applications your development team must invest their time in fixing bugs and patching holes, instead of developing your product and making it better.

It's costly to maintain

70% of IT bugets are consumed by legacy system maintenance

Legacy systems generate costs instead of profits. You can't optimize your revenue and get the maximum return on investment if you have to constantly pay to maintain non-functional software.

It's a blocker for scaling

87% of companies plan a software modernization within a year

Legacy systems block business growth and scaling because they are difficult to develop and modify. That's why handling tech debt is one of the most important strategic goals of leading  companies.

[ Key lessons from industry experts ]

"Modernization needs to be prioritized with a quantifiable value."

Martin Blomgren
Star Stable Entertainment

It's crucial to understand the impact of the change and from that drive the initiatives with as many and small deliveries as possible to minimise both the complexity and the disruptions.

Sam McAfee
Startup Patterns

Modernization needs to be prioritized with a quantifiable value if at all possible. It needs to be a first class item of work, not extra background work, or it will fail. It has to be funded, time-boxed, and put on a product roadmap as a full fledged project or initiative.

David Gebhardt
mobile.de GmbH

I could imagine that for some companies discussions on investments in modernization will not get easier with the current market conditions and more focus will be on creating direct, tangible user impact.

Our previous native app had bugs due to the development we’d done on the website, and Brainhub resolved all of those issues.

The team has been great at achieving our goals; thanks to them, we have a well-performing mobile app.
