Bespoke Software Development

Developing bespoke software to cater to the tactical and strategic needs of clients

Many, if not all, financial services firms struggle with some outdated technology solutions. Solutions which, over the course of their lifetime, increase in complexity due to architectural entropy and tactical change. The result is a sluggish, brittle, difficult-to-change legacy platform which becomes increasingly expensive to operate and maintain. Off-the-shelf vendor solutions can be a good solution for well defined, homogeneous use cases, however, not every use case has an off-the-shelf solution that is fit for purpose, cost efficient and has the flexibility to scale up organically. For specialised use cases, a custom-built solution may be the smart option to help firms tackle unique scenarios and allow progressive improvement toward a long-term objective. GreySpark’s team of specialist developers can help you develop bespoke software that can be scaled up as you grow your firm.

Our Value

While most technology owners understand the issues that the software they are responsible for poses, they often battle to secure buy-in and convince business stakeholders of the need for change. Frequently, GreySpark observes that either existing resources are not sufficient in terms of the time they have available, or their collective skillset comes up short for the task at hand.

The perceived cost to replace or upgrade legacy technology is difficult to qualify and estimate and the benefits are often difficult to articulate. All of which means that making the case for change problematic in today’s budget-constrained environment. Large-scale initiatives are often thought of as ‘too big to tackle’ by budget holders and implementers alike and, consequently, value-adding initiatives to automate and modernise IT platforms can be abandoned.

GreySpark works with clients to define and scope in-house software development projects, providing expertise and recommendations for technology stacks and software development practices. We can help you develop a minimum viable product (MVP) that suits the immediate needs of the business you service. All developed source code will be owned by you which allows you to further develop the software, operate and support it yourself.
