- Month 6: You're driving our culture programme forward, our management capabilities have noticeably improved, and your frameworks are helping teams work more effectively together. People challenges are being resolved efficiently and constructively
- Month 12: You've helped embed sustainable culture change, our engagement scores reflect real improvement, and we have the capabilities, metrics, and ways of working to thrive as we grow
- You'll be helping us navigate a thoughtful transition from startup to professional services excellence. Some days will require balancing competing priorities as we invest in our people while delivering exceptional client work

Our take
QuantSpark helps governments and businesses to strategically apply data science through the development of complex decision-making software. Primarily, its work involves analysing large datasets and systems in order to understand customer behaviour and help clients make informed decisions for strategic planning in sales and marketing.
In recent years, big data has become central to the operation of businesses large and small, and this has led to great demand for data scientists fluent in sophisticated modelling and analysis. QuantSpark seeks to go a step further, providing a service which combines data science with commercial insight- effectively providing both services through one transaction. By doing this, QuantSpark hopes to offer clients a more meaningful insight into their data than a standard consultancy could.
Already, the company has an impressive client list, including the UK Government, the Australian Government and Bain Capital. QuantSpark's tools and solutions are developed to become embedded in its clients' operations, ensuring a long-lasting relationship between them, and meaning that, as QuantSpark continues to expand its client base, its model should allow it to see continued success in the future.
